SYSTEM FOR DETECTING OBJECT AND METHOD FOR DETECTING OBJECT

A system acquires an image captured from a moving body moving on a track, and detects the track in the image. The system determines the width of the track at a reference ordinate value selected on the image, and determines the size of a region of interest in the image on the basis of the width of th...

Zusammenfassung:A system acquires an image captured from a moving body moving on a track, and detects the track in the image. The system determines the width of the track at a reference ordinate value selected on the image, and determines the size of a region of interest in the image on the basis of the width of the track and a coefficient. The system determines a positional coordinate of the region of interest in the image on the basis of the selected ordinate value and the detected track. The system executes a target-object detection process on the region of interest at the determined positional coordinate.
