We use Kinect to scan and obtain the 3D human body data first. Depth data transformation algorithm converts 2D depth data to the global coordinate system. ICP registration algorithm achieves infrared camera gesture tracking to obtain the states of infrared camera. TSDF algorithm integrates the converted vertex set into the pre-divided voxel lattice. Projection mapping algorithm is used for visualization of the reconstruct results. Using Kinect and auxiliary equipment tripod, we can quickly and easily achieve the results of human body 3D reconstruction and output the model with 3D print. This research realizes the whole process of human body 3D reconstruction including scanning, processing, reconstruction, and 3D model output.
