IMAGING-DIRECTION NORMALITY DETERMINATION METHOD, IMAGING DEVICE ATTACHMENT STATE EVALUATION PROGRAM, AND IMAGING DEVICE ATTACHMENT STATE EVALUATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a determination method, an evaluation program, and an imaging device attachment state evaluation device capable of evaluating the normality of the imaging direction of an imaging device.SOLUTION: An image processing device 100 comprises an acquisition unit 151, a calculation unit 152, and an evaluation unit 153. The acquisition unit 151 acquires image data of each frame number from a drive recorder etc. On the basis of image data of each frame number registered in drive recorder information 141, the calculation unit 152 generates an average difference image obtained by averaging the difference images of adjacent frame numbers. The evaluation unit 153 calculates the horizontal projection value of the average difference image and evaluate the attachment state of a camera, on the basis of the distribution of the horizontal projection value.
