Abstract

The invention provides a target detection method and device, electronic equipment and a storage medium, and the method comprises the steps: carrying out the feature extraction of a to-be-detected image, and obtaining a feature map of the to-be-detected image; based on the feature map, generating a depth map corresponding to a projection area where a target object in the to-be-detected image is projected to the ground; and determining three-dimensional detection information of the target object based on the depth map and the feature map. According to the invention, the projection area is associated with the target object to a certain extent, so that the depth map corresponding to the local ground can pertinently guide the feature map of the target object on the local ground to carry out three-dimensional detection, and the detection precision is improved.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular, to a target detection method, device, electronic equipment, and storage medium. Background technique [0002] Compared with two-dimensional (2D, 2-Dimension) target detection tasks, three-dimensional (3D, 3-Dimension) target detection tasks are more difficult and more complex, and often need to detect the 3D geometric information and Semantic information mainly includes the length, width, height, center point and orientation angle information of the target. Among them, the 3D target detection of monocular images is widely used in various fields (such as the field of unmanned driving) due to its economical and practical characteristics. [0003] However, 3D object detection techniques based on monocular images mainly rely on some external subtasks, which are responsible for performing tasks such as 2D object detection, depth map estimation, etc. Since the sub...
