IMAGING-DIRECTION TILT DETECTION METHOD, IMAGING-DIRECTION TILT DETECTION PROGRAM, AND IMAGING-DIRECTION TILT DETECTION DEVICE

摘要

PROBLEM TO BE SOLVED: To detect the tilt of an imaging direction on the basis of image data acquired by an imaging device.SOLUTION: An image processing device 100 comprises an acquisition unit 151, an extraction unit 152, and a detector 153. The acquisition unit 151 acquires image data of each frame number from a drive recorder etc. The extraction unit 152 extracts plural straight lines from the image data on the basis of drive recorder information 141. The detector 153 detects the tilt of the imaging direction of a camera in response to the angles formed with the extracted lines.
