評価装置、調査システム、評価方法及びプログラム
Document Type and Number:
Japanese Patent JP7115263
Kind Code:
B2
Abstract:
To solve the problem that a route to be measured has a start point and an end point decided for each of a plurality of measurement sections and road surface indications such as white lines are manually drawn with a spray etc., so as to specify the start points and end points, but since a road surface to be measured is long in distance, prior work for road surface property investigation requires great man-hours and burdens when road surface indications such as white lines are manually drawn.SOLUTION: An evaluation device 8 relates pairs of frame data on respective road surface images acquired at the same time T1 with measurement position data, and specifies a pair of frame data related to a measurement point Pm3 associated with measurement position data closest to an actual position Pfs associated with actual position data. The evaluation device 8 can use the specified pair of frame data to determine each evaluation section of a structure such as a road.SELECTED DRAWING: Figure 9
