The embodiment of the invention discloses an object detection method and device, electronic equipment and a storage medium. According to the embodiment of the invention, the method comprises the following steps of acquiring a point cloud of a scene wherein the point cloud comprises position information of points; mapping the point cloud to a three-dimensional voxel representation to obtain characteristic information of the three-dimensional voxel; carrying out convolution operation on the feature information of the three-dimensional voxels to obtain a convolution feature set; obtaining a candidate object area and initial positioning information of the candidate object area based on the convolutional feature set; selecting a target point located in the candidate object area from the point cloud; and based on the position information of the target point and the target convolution feature information, adjusting the initial positioning information of the candidate object area to obtain thepositioning information of the adjusted object area, the target convolution feature information being convolution feature information corresponding to the position of the target point in the convolution feature set. According to the scheme, the object detection accuracy can be improved.
Description
technical field [0001] The present invention relates to the field of image technology, in particular to an object detection method, device, electronic equipment and storage medium. Background technique [0002] Object detection refers to determining the position, category, etc. of objects in a certain scene. At present, object detection technology has been widely used in various scenarios, such as autonomous driving, drones and other scenarios. [0003] The current object detection schemes all collect scene images, extract features from the scene images, and then determine the location and category in the scene based on the extracted features. However, currently practiced target object detection schemes have problems such as low object detection accuracy, especially in 3D object detection scenarios. Contents of the invention [0004] Embodiments of the present invention provide an object detection method, device, electronic equipment, and storage medium, which can improv...
