Title:
STEREO CAMERA
Document Type and Number:
WIPO Patent Application WO/2019/058729
Kind Code:
A1
Abstract:
Provided is a stereo camera that is capable of reducing the distance error created by entrance pupil center movement between different principal ray angles of incidence. In the present invention, imaging system unit 100a images a standard image of an object. Imaging system unit 100b images a reference image of the object. A geometric correction information storage unit 114 stores geometric correction information for the standard image and reference image, which each have error depending on the differences between the positions of the object in the standard image and reference image if the entrance pupil center indicating the point of intersection between the principal ray and optical axis moves according to the angle of incidence and the positions of the object in the standard image and reference image if it is assumed that the entrance pupil center does not move according to the angle of incidence. The geometric correction unit 119 geometrically corrects the standard image and reference image using the geometric correction information.
