Title:
METHOD FOR IMAGING CALIBRATION FOR DUAL-LENS CAMERA, APPARATUS, AND DUAL-LENS CAMERA
Document Type and Number:
WIPO Patent Application WO/2021/037288
Kind Code:
A3
Abstract:
A method for imaging calibration for a dual-lens camera, an apparatus, and a dual-lens camera. The method comprises: obtaining a thermal imaging image containing a first calibration frame image and a visible light image containing a second calibration frame image, said first calibration frame image and second calibration frame image respectively being images of a same calibration frame captured by a thermal imaging camera and a visible light camera; obtaining a first position information of the first calibration frame image in the thermal imaging image and a second position information of the second calibration frame in the visible light image; according to the first position information and the second position information, generating calibration parameters; according to the calibration parameters, adjusting the position of the thermal imaging image in the visible light image, said thermal imaging image being synthesized into the visible light image. The present invention effectively enables precise calibration before products leave the factories and solves the problems of inability of fusing or seamlessly splicing imaging due to physical displacement or deformation after long periods of usage.
