Problems solved by technology
[0004] However, in the process of voxelization, different targets cannot be effectively distinguished, which will lead to poor accuracy of the detected multiple human center points. At the same time, since the above voxelization is carried out for the entire space , which will consume a lot of computation

The invention provides a three-dimensional point detection method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining a target image obtained by photographing a plurality of target objects at a plurality of visual angles, and determining the three-dimensional coordinate information of a candidate three-dimensional point of each target object in the plurality of target objects based on the obtained target image; for each target object, executing the following steps: determining a candidate three-dimensional space corresponding to the target object based on three-dimensional coordinate information of candidate three-dimensional points of the target object; and determining three-dimensional coordinate information of a target three-dimensional point of the target object based on the candidate three-dimensional space corresponding to the target object and the target image. The points of the multiple target objects can be accurately detected, and the detection efficiency can be remarkably improved.
Description
technical field [0001] The present disclosure relates to the technical field of artificial intelligence, and in particular, to a method, an apparatus, an electronic device, and a storage medium for three-dimensional point detection. Background technique [0002] Three-dimensional (Three-Dimensional, 3D) human pose estimation refers to estimating the pose of a human target from images, videos or point clouds, and is often used in various industrial fields such as human body reconstruction, human-computer interaction, behavior recognition, and game modeling. In practical application scenarios, there is often a need for multi-person pose estimation. Among them, human center point detection can be used as a pre-task for multi-person pose estimation. [0003] The related art provides a human body center point detection scheme, which performs multi-view feature extraction based on 3D space voxelization, and detects the human body center point through a convolutional neural networ...
