Abstract: A high-precision map construction method, apparatus, and electronic device are provided. The method can include: displaying a first color image corresponding to a first track point; according to a first color sub-image and a depth image corresponding to the first track point, obtaining point cloud data corresponding to the first sub-color image, wherein the first sub-color image is a sub-image corresponding to an element to be added in the first color image, and the element to be added is an element to be added in a high-precision map for display; extracting a bounding box corresponding to the point cloud data; and generating a newly-added three-dimensional element according to the bounding box in the high-precision map.

Abstract: The present disclosure provides a method for generating a bounding box and an apparatus for generating a bounding box, a device and a storage medium, which relate to the field of artificial intelligence, and in particular, to the technical fields of computer vision, cloud computing, intelligent search, Internet of Vehicles, and intelligent cockpits. The specific implementation solution is as follows: acquiring a depth map to be processed and depth information corresponding to the depth map; capturing a selection action by a user for a target object on the depth map; then, based on the selection action, determining, in the depth information, boundary point cloud information of the target object; and finally, based on the boundary point cloud information, generating a bounding box of the target object.
