Title:
IMAGE PROCESSING DEVICE AND STEREO CAMERA DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2021/049250
Kind Code:
A1
Abstract:
Provided are an image processing device capable of reducing an error in parallax calculation in a stereo matching process, and a stereo camera device using the same. The present invention is provided with: geometric correction units (geometric correction (right) unit 26 and geometric correction (left) unit 25) which correct distortion of images taken by a plurality of rolling shutter-type image sensors 220 and 210; a parallax calculation unit 30 which calculates parallax by using the corrected image corrected by the geometric correction unit; and an exposure time difference adjusting unit 60 which, on the basis of a difference between a geometric correction amount (geometric correction table right 28) used for distortion correction of a reference image (right image) taken by the pixel sensor 220 and a geometric correction amount (geometric correction table left 27) used for distortion correction of another image (left image) taken by the pixel sensor 210, and vehicle information regarding the position or movement of the vehicle, adjusts the geometric correction position of at least one image (left image).
