Multi-view Multi-person 3D Human Pose Estimation Based on Center-point Attention

Multi-view multi-person 3D human pose estimation is widely used in various computer vision tasks.Current spatial voxel-based methods are difficult to achieve real-time computing on edge computing devices due to huge resource consumption.However,the regression method has limited generalization ability due to the lack of geometric constraints.In a new environment,it cannot be directly applied and needs to collect data for fine-tuning.By combining the spatial voxel method and the regression-based pose estimation method,we propose a multi-view multi-person 3D human pose estimation model based on center point attention regression.The model roughly estimates the position of the human body center through a small-scale voxel network,and constructs the initial pose based on it.Then the regression prediction is carried out within the range of the human body center point to obtain more accurate human pose.In this study,by combining the spatial key point positions,the regression prediction of the model is more accurate,and the average accuracy is improved by 1.16% on large scales.At the same time,the model is very easy to train,and the accuracy is improved by up to 12% in small sample fine-tuning.This allows regression-based models to greatly expand the generalization performance and versatility of such models in new scenarios by rapidly deploying them with small amounts of training data.
