3D Human Body Recognition And Reconstruction Based On Kinect

The applications related to 3d human body models have been used in all areas now, so the ways we get 3d human body information and the methods we reconstruct 3d human models are worthy of in-depth study. This article first tells the significance and current situation of 3d human models reconstruction research, then describes all kinds of methods and principles to achieve human body 3d reconstruction in detail. The core work of this paper is that the Kinect device is used for 3d human body information acquisition, and the point cloud library is combined to realize 3d human body reconstruction.For 3d human body reconstruction process based on the device, the first step is using two devices simultaneously to collect the 3d data of the upper and lower body of a human separately. After comparing various ways of using the device for human body information acquisition, we finally determined using Processing programming for 3d human body information acquisition which can obtain a complete 3d human body data and does not need too much complicated process.The next step is to transfer the human body 3d information into point cloud data that can be taken in point cloud library for processing. As the biggest open source platform, Point Cloud Library provides multiple implementation approaches of point cloud processing method. In this article, through a preprocessing stage, such as removing background, choose the reference model, coordinate transformation and so on, the point cloud data can be operated further. Then we fused the point cloud data of upper body and lower body and registered the fused point cloud to minimize error, which can be used for point cloud down-sampling. The best sampling model will be registered from reference model as the target model, through constant adjustment shape coefficient of the reference human body model to complete the 3d human body reconstruction. The results demonstrate that this experiment is feasible in design and methodology. And the advantages of this method just as low-cost, high-speed, and convenience are especially suitable for 3d games and comics.
