Abstract
The present application relates to a method, a device, and a non-transitory computer-readable medium for simultaneously positioning and mapping. The method for simultaneous positioning and mapping includes: obtaining a large field of view image through a large field of view camera; obtaining an undistortion image corresponding to the large field of view image based on a multi-virtual pinhole camera model; and determining the pose of the large field of view camera based on the undistortion image and creating a map. The multiple virtual pinhole camera model includes at least two virtual pinhole cameras with different orientations, and a camera center of the at least two virtual pinhole cameras with different orientations coincides with a camera center of the large field of view camera.
