Title:
POINT CLOUD GENERATION METHOD AND DEVICE, AND IMAGE DEPTH INFORMATION DETERMINATION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/205209
Kind Code:
A1
Abstract:
A three-dimensional point cloud generation method and device, and an image depth information determination method and device. In the process of acquiring a target image by a rolling shutter image acquisition device, a motion state parameter of the rolling shutter image acquisition device is acquired at the same time, and is associated with a target image for storage. When a three-dimensional point cloud is generated on the basis of the target image, pose information of each row of image data acquired by the rolling shutter image acquisition device can be solved by using the motion state parameter as an initial value or a constraint, such that the calculated amount of the aerial triangulation process is greatly reduced, the determined pose information is also more accurate, and the generated three-dimensional point cloud precision is also higher.
