Title:
POSITIONING INITIALIZATION METHOD AND APPARATUS, AND COMPUTER-READABLE STORAGE MEDIUM AND COMPUTER PROGRAM PRODUCT
Document Type and Number:
WIPO Patent Application WO/2023/087681
Kind Code:
A1
Abstract:
Disclosed in the present disclosure are a positioning initialization method and apparatus, and a computer-readable storage medium and a computer program product. The positioning initialization method comprises: acquiring a priori information of state variables of a positioning device in a static state; determining initial values of the state variables on the basis of the a priori information of the state variables, wherein the state variables are used for performing positioning, and comprise a visual state variable and an inertial state variable; updating the state variables during the running of a positioning process; and when determining that the updated state variables satisfy convergence, determining that positioning initialization is complete. By means of the solution, an initialization process can have relatively high stability.
