POSITIONING METHOD, POSITIONING APPARATUS, METHOD OF GENERATING VISUAL MAP, AND APPARATUS THEREOF

Japanese Patent JP2023021469

A

To provide a positioning method, a positioning apparatus, a method of generating a visual map, and an apparatus thereof.SOLUTION: A positioning method includes acquiring a parking space number corresponding to a parking space image, acquiring a three-dimensional coordinate and a three-dimensional attitude of the parking space number in a global coordinate system based on the parking space number and a visual map generated based on the parking space number, acquiring a first transformation matrix from a camera coordinate system to a parking space number coordinate system to construct the parking space number coordinate system based on the parking space number, and determining the three-dimensional coordinate and the three-dimensional attitude of the camera in the global coordinate system based on the first transformation matrix and the three-dimensional coordinate and the three-dimensional attitude of the parking space number.SELECTED DRAWING: Figure 1
