TRAFFIC SITUATION ANALYZER, TRAFFIC SITUATION ANALYZING METHOD, AND TRAFFIC SITUATION ANALYSIS PROGRAM

摘要

PROBLEM TO BE SOLVED: To accurately estimate, on the basis of an image input from an imaging apparatus that images a predetermined area on a road, behavior of an object relating to a traffic situation in the predetermined area and moving on the road.SOLUTION: An intersection analyzer 1 comprises: a background difference calculating section 21 that calculates a background difference image BDt, which is a difference between an input image It that receives input from a camera 5 for imaging an intersection, and a background image BGt-1 relating to background information of the intersection; an object detecting section 3 that calculates identification information and movement vector of at least one object M[k] relating to a traffic situation at the intersection and moving on the road of the intersection, from the background difference image BDt calculated by the background difference calculating section 21; and a behavior interpretation section 4 that estimates the behavior A[k] of an object M[k] having identification information of the intersection, on the basis of the identification information and movement vector information of the object M[k] detected by the object detecting section 3.SELECTED DRAWING: Figure 1
