Title:
IMAGING DISTANCE MEASUREMENT SENSOR, METHOD, AND SYSTEM, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/088913
Kind Code:
A1
Abstract:
The present application is applicable to the technical field of time of flight, and provides an imaging distance measurement sensor, method, and system, and a storage medium. The imaging distance measurement sensor comprises a plurality of pixels arranged in an array form; each pixel comprises at least four sub pixels arranged in an array form; each sub pixel comprises a single-photon photosensitive unit and an optical filter covering the single-photon photosensitive unit; and the at least four sub pixels comprise an infrared sub pixel, a red sub pixel, a green sub pixel, and a blue sub pixel, so that one imaging distance measurement sensor can have the function of simultaneously obtaining depth information and RGB information. A depth image obtained on the basis of the depth information and an RGB image obtained on the basis of the RGB information have no viewing angle difference, and alignment is not needed when image fusion is performed on the depth image and the RGB image, and thus, an operation resource and time can be effectively reduced.
