IMAGING DEVICE FOR AUTONOMOUSLY MOVABLE BODY, CALIBRATION METHOD THEREFOR, AND CALIBRATION PROGRAM THEREFORE

摘要

PROBLEM TO BE SOLVED: To provide an imaging device for an autonomously movable body which performs autonomous calibration for the imaging device. SOLUTION: The imaging device is installed on the autonomously movable body which comprises: an image-taking section for taking images of the surrounding environment; and an object detecting section for detecting circumferential objects and obstacles by processing the obtained images. The imaging device comprises: an image processing section to perform color detection of the images taken by the image-taking section; a white calibration plate for the image-taking section to perform color correction; and a calibration plate control section for moving the calibration plate into a field of view of the image-taking section. Color correction is performed using the calibration plate when it is determined that the images taken by the image-taking section do not provide color information sufficient to perform color detection.
