Title:
METHOD FOR IMPROVING UNEVEN LIGHT INTENSITY OF STRIPES, CAMERA, STORAGE MEDIUM, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/083274
Kind Code:
A1
Abstract:
The present application provides a method for improving uneven light intensity of stripes, a camera, a storage medium, and a program. The method comprises: forming grating stripes on a projection surface by using a structured light depth camera; taking a plurality of calibration points on a straight line which is perpendicular to the grating stripes, wherein the number of the calibration points is greater than the number of the grating stripes; and adjusting the rotation angle speed of a galvanometer of the structured light depth camera in a segmented manner according to a grayscale value of each calibration point. The accuracy of a subsequent image recognition result is improved.
