INFRASTRUCTURE DIAGNOSTIC DEVICE, INFRASTRUCTURE DIAGNOSTIC METHOD, AND RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/176198
Kind Code:
A1
Abstract:
The present invention manages a state of a road infrastructure with segments that conform to the current road. A segment generating unit 2 generates road segments by dividing the movement paths of moving bodies, collected from the moving bodies that move along a road, into a mesh obtained by dividing the ground surface into predetermined sizes. A state assessing unit 3 assesses the states of the road segments on the basis of sensor information of the road segments collected from the moving bodies, and outputs the states of the road segments.
