ABNORMAL IMAGE DETECTION DEVICE, IMAGE PROCESSING SYSTEM HAVING ABNORMAL IMAGE DETECTION DEVICE, AND VEHICLE INCORPORATING IMAGE PROCESSING SYSTEM

摘要

An abnormal image detection device includes a reliability determination part that determines whether or not each pixel of a parallax image has a low reliability. The reliability determination part has an edge intensity determination section. For each respective pixel of original images, the edge intensity determination section determines whether or not the respective pixel is smaller than or equal to a threshold value, and if the respective pixel is smaller than or equal to the threshold value, the reliability determination part determines that a corresponding one of the pixels in the parallax image, which corresponds to the respective pixel, is a pixel having the low reliability. A computation part computes a total number of pixels of the parallax image that each has the low reliability. An abnormality determination part that when the total number of pixels exceeds a predetermined value, determines that the parallax image is abnormal.
