Description

The present invention relates to a method, program, device, and three-dimensional object for producing a three-dimensional object that represents changes in scent over time.

Conventionally, products that emit scents such as perfumes are made by mixing multiple fragrances. Among the plurality of fragrances, fragrances are emitted in order from the most volatile to the least volatile, so the fragrance of perfumes and the like changes over time. This change in fragrance is also called scent development, and the changing scent is also called top note, middle note, and last note in the order of time.

Regarding changes in scent, Patent Document 1 discloses that a first video showing changes over time in the appearance of an object and a second video showing changes over time in the amount or ratio of aroma components corresponding to the object in a graph format are arranged in chronological order. It is disclosed that a display that is reproduced in association with each other is outputted (paragraph [0014] of Patent Document 1).

Patent No. 6532847

However, for example, the change in the scent that a person, such as a perfumer, feels when actually smelling the scent is not necessarily linked to the change in the amount or ratio of the aroma components described in Patent Document 1.

Therefore, one embodiment of the present invention aims to present two differences in changes in fragrance over time.

One aspect of the present invention is to obtain a time series of a first index of the scent that a person feels when smelling the scent, and a time series of a second index of the scent that is measured by a measuring device; The method includes the step of generating three-dimensional shape information of a three-dimensional object representing a change over time in the first index and the second index based on each of the acquired time series.

According to one embodiment of the present invention, it is possible to present the difference between two changes in fragrance over time.

Although this specification mainly describes the scent of perfume, the present invention also applies to any scent emitted by any object (for example, the scent emitted by a product, the scent emitted by animals and plants, the scent in a space or place, etc.) ) can be applied.

Furthermore, the term "fragrance" as used herein may be anything that wafts through the air and stimulates the sense of smell, and includes not only pleasant odors such as perfumes but also odors that cause discomfort such as malodors.

<Overall configuration>
FIG. 1 is an overall configuration diagram according to an embodiment of the present invention. As shown in FIG. 1, the generation device 10 can send and receive data to and from the first index input terminal 20 and the second index input terminal 30 via any network or storage medium. Further, the second index input terminal 30 can acquire data measured by the measuring device 40 via any network or storage medium. Each will be explained below.

The first index input terminal 20 is a terminal into which a first index of fragrance is input. The first indicator of scent is the indicator of the scent that a person feels when smelling a scent. For example, the first indicator of scent is the intensity and quality of the scent that a person feels when smelling a scent. The first index input terminal 20 stores a time series of indexes of the scent that a person feels when smelling a scent, which are input to the first index input terminal 20 (for example, input by a person such as a perfumer). The data is passed to the generation device 10 via a network or storage medium. The first index input terminal 20 may be any terminal such as a personal computer.

The second index input terminal 30 is a terminal into which a second index of fragrance is input. The second scent index is a scent index measured by the measuring device 40. For example, the second index of fragrance is the component and the amount of the component contained in the scent, which is measured by the measuring device 40. The second index input terminal 30 transmits time-series data of the fragrance index measured by the measurement device 40, which is input to the second index input terminal 30 (for example, acquired from the measurement device 40), through a network or storage. It is passed to the generation device 10 via a medium. The second index input terminal 30 may be any terminal such as a personal computer.

The measuring device 40 is a device that measures the second index of fragrance. The measuring device 40 can measure components and amounts of components contained in a fragrance. For example, measurement device 40 is a proton transfer reaction mass spectrometer (PTR-MS). Note that the measurement device 40 is not limited to PTR-MS, but may be any measurement device such as DART-MS, gas chromatography, or a sensor.

Here, PTR-MS will be explained. PTR-MS is an online chemical ionization mass spectrometer that utilizes a proton transfer reaction caused by hydronium ion H ₃ O ⁺ . In one embodiment of the present invention, by using PTR-MS, it becomes possible to qualitatively and quantitatively quantify the vaporization of fragrance into the air for each fragrance component in real time, as well as changes over time. .

The generation device 10 generates a three-dimensional object representing a change over time in the first index and the second index based on the time series of the first index of scent and the time series of the second index of scent. Generate shape information. The generation device 10 consists of one or more computers. Furthermore, the generation device 10 can acquire data from the first index input terminal 20 and the second index input terminal 30 via any network or storage medium. The generation device 10 will be described in detail later with reference to FIG. 2.

Although the first index input terminal 20 and the second index input terminal 30 are described as separate devices in FIG. 1, they may be implemented as one device. Furthermore, the generation device 10 may have at least part of the functions of the first index input terminal 20 and the second index input terminal 30.

<Functional block>
FIG. 2 is a functional block diagram of the generation device 10 according to an embodiment of the present invention. As shown in FIG. 2, the generation device 10 includes an acquisition section 101 and a generation section 102. Furthermore, the generation device 10 functions as an acquisition unit 101 and a generation unit 102 by executing a program.

The acquisition unit 101 acquires a time series of a first fragrance index and a time series of a second aroma index. Hereinafter, the first index and the second index will be explained separately.

<First indicator>
The acquisition unit 101 acquires time-series data of the first fragrance index from the first index input terminal 20 via any network or storage medium. As mentioned above, the first indicator of scent is the indicator of the scent that a person feels when smelling the scent. The first indicator of scent can be any index that a person can feel when smelling the scent, such as the strength of the scent, the quality of the scent, or the mood felt when smelling the scent. It's fine. That is, the first index of scent indicates the actual feeling of scent (that is, what is felt when smelling the scent) as evaluated by a person. Moreover, one index may be used as the first index of fragrance, or a plurality of indexes may be used in combination.

For example, the first indicator of scent is the intensity and quality of the scent that a person feels when smelling a scent. The time series of scent intensity and the time series of scent quality will be described below with reference to FIGS. 3 and 4.

<<Strength of scent>>
FIG. 3 is an example of a time series of scent intensity according to an embodiment of the present invention. Fragrance intensity indicates the strength of the scent. For example, scent intensity can be evaluated using the following 6-level odor intensity scale.
5: Strong odor 4: Strong odor 3: Easily detectable odor 2: Weak odor that allows you to know what kind of odor it is (cognitive threshold)
1: Smell that can barely be detected (detection threshold)
0: Odorless

As shown in FIG. 3, a person such as a perfumer, etc., at a predetermined time (in the example of FIG. After 360 minutes), the strength of the scent (for example, which of the six levels listed above) is evaluated.

＜＜Fragrance quality＞＞
FIG. 4 is an example of a time series of fragrance quality according to an embodiment of the present invention. Fragrance quality indicates the type of scent. For example, the scent quality is the type of scent such as musky, amber, woody, floral, fruity, green, citrus, etc. perfume.

As shown in FIG. 4, a person such as a perfumer, at a predetermined time (in the example of FIG. After 360 minutes), the types of fragrances and the proportion of each type of fragrance to the total (that is, which types of fragrances are strong and which types are weak) are evaluated.

Note that in order to prevent the sense of smell from acclimatizing, a person such as a perfumer may refrain from smelling scents except at predetermined times.

<Second indicator>
The acquisition unit 101 acquires time-series data of the second fragrance index from the second index input terminal 30 via any network or storage medium. As mentioned above, the second aroma index is the aroma index measured by the measuring device. Note that the second index of fragrance may be any index as long as it can be measured by the measuring device. That is, the second index of fragrance indicates the actual state of the fragrance (that is, the behavior of the fragrance components) evaluated by the measuring device. Further, as the second indicator of fragrance, one indicator may be used, or a plurality of indicators may be used in combination.

For example, a second indicator of scent is one or more components and the amount of each component contained in the scent as measured by a measurement device (eg, PTR-MS). Hereinafter, with reference to FIG. 5, the time series of components and amounts of components contained in fragrance will be described.

<<Ingredients and amounts of ingredients contained in the fragrance>>
FIG. 5 is an example of actual measured values of PTR-MS according to an embodiment of the present invention. As shown in FIG. 5, PTR-MS measures the components contained in a fragrance and the amount of each component.

Generate shape information. The generation unit 102 creates a graph of the first index and a graph of the second index, and generates three-dimensional shape information based on the graph of the first index and the graph of the second index. Hereinafter, generation of three-dimensional shape information will be explained in detail with reference to FIGS. 6 to 10.

<Creating a graph of the first indicator>
The generation unit 102 creates a stacked area graph as shown in FIG. 6 based on the strength of the scent (for example, the graph in FIG. 3) and the quality of the scent (for example, the graph in FIG. 4).

Specifically, at each point in time, the generation unit 102 calculates the strength of each type of scent by multiplying the "strength of the scent" by the "ratio of each quality (that is, each type) to the total scent." calculate. Further, the generation unit 102 displays the time series of the intensity of each type of scent as an area, and creates a stacked area graph by stacking the areas of the intensity of each type of scent. Note that the generation unit 102 displays the strength of each type of scent in different colors, patterns, etc. so that they can be easily distinguished.

FIG. 6 is an example of a time series (stacked area graph) in which scent strength and scent quality are multiplied according to an embodiment of the present invention. As shown in FIG. 6, changes over time in the scent intensity of each quality (that is, each type) are shown.

Note that the generation unit 102 may be configured to create a bar graph as shown in FIG. 7 instead of an area graph such as the stacked area graph in FIG. 6.

<Creating a graph of the second indicator>
The generation unit 102 performs smoothing on the actual measured values of each component measured by a measuring device (for example, PTR-MS). Specifically, the generation unit 102 creates an approximate curve of the actual measured values of each component measured by a measuring device (for example, PTR-MS).

FIG. 8 is a diagram for explaining smoothing of actual measured values of PTR-MS according to an embodiment of the present invention. For example, on the left side of FIG. 8, an approximate curve of the measured PTR-MS values of "MUSCENONE", which is a musk-like component contained in a fragrance, is shown. Further, on the right side of FIG. 8, an approximate curve of the measured PTR-MS values of "LIMONENE", which is a citrus-like component contained in the fragrance, is shown.

The generation unit 102 stacks up the approximate curves of each component that have been smoothed as described with reference to FIG. 8 to create a stacked area graph as shown in FIG. 9 . Note that the generation unit 102 can also be configured to create a stacked area graph by stacking up the measured values of each component that have not been smoothed.

Specifically, the generation unit 102 displays the time series of the amounts of each component contained in the fragrance as a surface, and stacks the surfaces of the amounts of each component to create a stacked area graph. Note that the generation unit 102 displays the amounts of each component in different colors, patterns, etc. so that they can be easily distinguished.

FIG. 9 is an example of an approximate curve (stacked area graph) based on actual measured values of PTR-MS according to an embodiment of the present invention. As shown in FIG. 9, changes in the amount of each component over time are shown.

Here, in the stacked area graph, the first aroma index side (that is, the strength of each type of scent) and the second aroma index side (that is, the amount of each component contained in the scent) This section explains the correspondence between The generation unit 102 can display the intensity of a certain type of fragrance and the amount of a component corresponding to that type (for example, emitting that type of fragrance) in the same color, pattern, etc. can.

<Generation of 3D shape information>
FIG. 10 is an example of three-dimensional shape information according to an embodiment of the present invention. The generation unit 102 generates three-dimensional shape information as shown in FIG. 10 based on the stacked graph of the first scent index and the stacked graph of the second scent index.

For example, the generation unit 102 sets the axis indicating time as the x-axis, the axis indicating the first index of scent (that is, the intensity of each type of scent) as the y-axis, and the second index of scent (that is, Three-dimensional shape information (that is, x-axis coordinates, y-axis coordinates, and z-axis coordinates) is generated, with the z-axis representing the amount of each component contained in the fragrance. Note that the generation unit 102 can interpolate (or interpolate) values of coordinates other than the plane where the x-axis and the y-axis intersect and the plane where the x-axis and the z-axis intersect.

The generation unit 102 outputs three-dimensional shape information. For example, the generation unit 102 can cause a 3D printer to output a three-dimensional object based on the generated three-dimensional shape information. Note that the generation unit 102 can also be configured to display 3DCG (three-dimensional computer graphics) of a three-dimensional object on a display device such as a display.

<Processing method>
FIG. 11 is a flowchart of generation processing according to an embodiment of the present invention.

In step 11 (S11), the acquisition unit 101 acquires time-series data of the first fragrance index from the first index input terminal 20. As mentioned above, the first indicator of scent is the indicator of the scent that a person feels when smelling the scent.

In step 12 (S12), the acquisition unit 101 acquires time-series data of the second fragrance index from the second index input terminal 30. As mentioned above, the second aroma index is the aroma index measured by the measuring device.

Note that the order of S11 and S12 may be reversed.

In step 13 (S13), the generation unit 102 generates the first index and the second index based on the time series of the first index of scent and the time series of the second index of scent acquired in S11 and S12. Three-dimensional shape information of a three-dimensional object representing changes over time with respect to the index is generated.

Specifically, at each point in time, the generation unit 102 calculates the strength of each type of scent by multiplying the "strength of the scent" by the "ratio of each quality (that is, each type) to the total scent." calculate. Further, the generation unit 102 displays the time series of the intensity of each type of scent as an area, and creates a stacked area graph by stacking the areas of the intensity of each type of scent.

Next, the generation unit 102 displays the time series of the amounts of each component contained in the fragrance as a surface, and stacks the surfaces of the amounts of each component to create a stacked surface graph. Note that the order of creating the stacked graph of the first index and the stacked graph of the second index may be reversed.

Next, the generation unit 102 generates three-dimensional shape information based on the stacked area graph of the first scent index and the stacked area graph of the second scent index.

In step 14 (S14), the generation unit 102 outputs the three-dimensional shape information generated in S13. For example, the generation unit 102 can cause a 3D printer to output a three-dimensional object based on the three-dimensional shape information generated in S13. Note that the generation unit 102 can also be configured to display 3DCG (three-dimensional computer graphics) of a three-dimensional object on a display device such as a display.

<Effect>
Thus, in one embodiment of the present invention, a subjective indicator of scent (i.e., a first indicator of the scent that a person perceives when smelling) and an objective indicator of scent (i.e., a measured Changes in scent can be visualized by digitizing the two indicators (second index of scent measured by the device) and creating a three-dimensional object that represents changes in scent over time. Therefore, it is possible to see and touch the real image of changes in fragrance, which cannot be seen with the naked eye, while simultaneously comparing them from two viewpoints: a subjective index and an objective index.

It is possible to generate three-dimensional shape information of a three-dimensional object that represents changes over time in the index and the index of the scent that the same person feels when smelling a different scent. Therefore, it is possible to compare how different scents are perceived.

<In the case of objective indicators and objective indicators>
For example, the generation device 10 generates a scent index when one measuring device measures a certain scent and another measuring device based on a time series of scent indices when different measuring devices measure the same scent. It is possible to generate a three-dimensional shape of a three-dimensional object that represents the change over time of the scent index when the same scent is measured. Therefore, it is possible to compare the results of measurements made by different measuring instruments.

For example, the generation device 10 generates a scent index when a certain measuring device measures a certain scent based on a time series of scent indices when the same measuring device measures different scents, and a scent index when the same measuring device measures a certain scent. When the device measures another scent, it is possible to generate an index of the scent and three-dimensional shape information of the three-dimensional object representing changes over time.
