OBJECT DETECTION METHOD AND APPARATUS, AND NETWORK DEVICE AND STORAGE MEDIUM

Disclosed are an object detection method and apparatus, and a network device and a storage medium. In the embodiments of the present application, a foreground point can be detected from a point cloud of a scene; a candidate object area corresponding to the foreground point is constructed on the basis of the foreground point and a predetermined size to obtain initial positioning information of the candidate object area; feature extraction is carried out on all points in the point cloud on the basis of a point cloud network to obtain a feature set corresponding to the point cloud; area feature information of the candidate object area is constructed on the basis of the feature set; the type and positioning information of the candidate object area are predicted on the basis of an area prediction network and the area feature information to obtain the predicted type and the predicted positioning information of the candidate object area; and the candidate object area is optimized on the basis of the initial positioning information of the candidate object area and the predicted type and the predicted positioning information of the candidate object area to obtain a target object detection area and positioning information of the target object detection area. The solution can improve the accuracy of object detection.
