MAP CONSTRUCTION METHOD, APPARATUS, DEVICE AND STORAGE MEDIUM

Embodiments of the present invention disclose a map construction method, apparatus, device, and storage medium. The method includes the following steps: acquiring sensor data collected by a preset sensor; establishing a pose constraint relationship of a movable object and a semantic constraint relationship of a semantic object according to the sensor data; performing a joint optimization solution according to the pose constraint relationship and the semantic constraint relationship to determine a semantic result of the semantic object and a pose result of the movable object; and constructing a semantic map and a point cloud map according to the semantic result and the pose result. By adopting the above technical solution, the semantic map and the point cloud map can be obtained quickly and accurately, thereby obtaining a more accurate high-definition map.
