Title:
POSITION ADJUSTMENT METHOD AND APPARATUS, AND DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/001960
Kind Code:
A1
Abstract:
The present disclosure relates to a position adjustment method and apparatus, and a device and a storage medium. The method comprises: acquiring all scanning frames, which are collected by means of a camera, at the current position, in a target scanner; calculating a global error of all the scanning frames at the current position on the basis of a feature point pair in adjacent scanning frames and a gravity center point pair in each scanning frame, wherein the gravity center point pair comprises the real gravity center of each scanning frame and a theoretical gravity center, which is acquired by means of an inertial measurement unit in the target scanner; and if the global error does not meet a preset optimization condition, adjusting the current position of the camera until a global error corresponding to the adjusted current position meets the preset optimization condition, so as to obtain the adjusted current position of the camera. Therefore, during the process of adjusting the position of the camera, the global error is calculated by taking feature information of adjacent scanning frames and the gravity center of each scanning frame into consideration, and the position of the camera is adjusted on the basis of the global error, such that the position adjustment precision of the camera can be ensured.
