POSE DETERMINATION METHOD AND APPARATUS, AND ELECTRONIC DEVICE AND STORAGE MEDIUM

A pose determination method and apparatus, and an electronic device and a storage medium, which belong to the field of simultaneous localization and mapping. The method is executed by an electronic device, and comprises: determining a first two-dimensional plane point in a first video frame, wherein the first two-dimensional plane point is within a display area of a target horizontal plane (201), and the target horizontal plane is the imaging content of a horizontal plane in the real world in the first video frame; acquiring first attitude information of a camera when the first video frame is collected (202); determining, in a camera coordinate system of the camera, a first coordinate of a first three-dimensional space point corresponding to the first two-dimensional plane point in the real world (203), wherein the first three-dimensional space point is the origin of a world coordinate system; and according to the first attitude information and the first coordinate, determining a pose of the camera corresponding to the first video frame in the world coordinate system (204).
