JP7315909B2 - Computer system for visualizing soundness of crosswalk markings - Google Patents

Description

The present invention relates to a computer system that visualizes the soundness of crosswalk markings on a map by color.

On roads, road markings such as white lines indicating crosswalks and various character symbols, and marking lines indicating driving lanes and the like are drawn with coating films such as fusible paints and paints.
Among them, for road markings such as pedestrian crossings on the road surface, there is a method of judging the deterioration of the road markings by photographing the road markings and using computer software from the coordinate information and the image of the road markings. It is conventionally known (see Patent Document 1, for example).

Japanese Unexamined Patent Application Publication No. 2017-20303

Road markings need to be maintained in good condition at all times, as traffic regulations will be ineffective if they are not properly installed and managed along with road signs.
In particular, road markings on pedestrian crossings must be updated as soon as possible if they are worn out, etc., so as not to endanger pedestrians crossing the road.
However, there is a situation in which administrators such as the government and construction contractors have to manage a huge number of stocks. In addition, since the state of wear and tear greatly depends on the road environment such as traffic volume, the administrator will comprehensively look at the state of wear and tear on crosswalks within the jurisdiction, and then prioritize and judge whether to renew the pedestrian crossings. is extremely important.
It would be extremely convenient if the wear and tear of crosswalks, etc., could be graded and displayed on a map as a guideline for administrators to select crosswalks with high priority for updating. .
The present invention provides a computer system that analyzes the wear rate of pedestrian crossings using dedicated software, ranks the pedestrian crossings according to their soundness, and displays the ranks of the soundness of pedestrian crossing markings on the computer screen. Main purpose.
In addition, the present invention analyzes the wear rate of crosswalks with dedicated software, and assigns colors such as red, yellow, and blue to the marking marks of crosswalks on a map of the jurisdiction area according to the soundness of the crosswalks. , to provide a computer system that ranks the soundness of pedestrian crossings and displays them on a computer screen.

This system consists of a smartphone 4 installed with application software 2 for photographing pedestrian crossings, and an application for visualizing the soundness of pedestrian crossing markings. A computer 8 on which software 6 is installed, and the computer 8 is connected to the Internet 10 .
FIG. 3 shows the configuration of the application software 2. As shown in FIG. The application software 2 receives an operation signal from the user and inputs it to the information processing section 12, and an input/output interface section 14 for exchanging signals with the Internet 10. A photographing unit 16 that photographs a crosswalk, displays it on the screen of the smartphone 4, and creates image data from the displayed image; It is composed of an automatic direction recording unit 18 and a data recording unit 20 for adding data such as the jurisdictional name/inscription, control number, and other memos to the image data.

To shoot with the smartphone 4, as shown in FIG. 6, the pedestrian crossing sign 30 and the notice mark (see FIG. 5B) are displayed on the screen 27 of the smartphone 4, and the green dot marker 29 on the screen 27 is clicked. As a result, the latitude and longitude of the clicked position on the screen 27 is added to the image as data.
FIG. 4 shows the configuration of the application software 6. As shown in FIG. The application software 6 receives a personal computer operation signal from a user, a signal from the Internet 10 and an external electronic device, inputs them to the information processing section 22, and inputs/outputs the internal data of the computer 8 to an external device. The four corners of the interface unit 24, the crosswalk marking diagnostic target identifying unit 26, and the crosswalk marking image 30 (see FIG. 7) displayed on the computer screen 28 are designated by a pointing device such as a mouse or touch panel, and the screen 28 is displayed. a crosswalk marking wear rate calculation unit 32 for calculating the wear rate of the crosswalk marking image 30 displayed on the screen 28 when the calculation button is pressed; a data storage unit 34 for storing data on the wear rate; A crosswalk marking installation location display portion 36, a crosswalk type list display portion 38, a wear rate list display portion 40, a list display portion 42 of the number of stripes of crosswalk markings, and a wear rate rank colored map display portion 44. , a quantity display section 46 for each wear rate, a crosswalk marking soundness ranking display section 48 that ranks and displays the crosswalk markings based on the wear rate of the crosswalk markings, and a crosswalk marking diagnosis data display section 50. consists of

The wear rate of the pedestrian crossing sign is the percentage of the white line portion of the pedestrian crossing that shows the paved portion of the road, and is expressed as a percentage.
In the above-described configuration, when the green dot marker 29 on the screen 27 of the smartphone 4 is clicked, the image information of the pedestrian crossing and the warning mark taken with the smartphone 4, the latitude/longitude/azimuth (shooting direction), the jurisdiction, etc. are displayed on the computer. 8 is stored in the data storage unit 34 .
