Document Type and Number:
WIPO Patent Application WO/2023/024903
Kind Code:
A1
Abstract:
The present invention relates to a method for accurately positioning a navigation target point, comprising: selecting a navigation reference object at a fixed position, acquiring the positions of both the navigation reference object and a navigation target point in a navigation coordinate system, and calculating the position of the navigation target point relative to the navigation reference object, thereby obtaining the position of the navigation target point in a navigation reference object coordinate system. In the present invention, as long as the navigation reference object does not move, the navigation reference object coordinate system does not change throughout a navigation process, and a position parameter of the navigation target point in the navigation reference object coordinate system will not be disturbed by the navigation coordinate system.
