Method for generating 3d skeleton using joint-based calibration acquired from multi-view camera

Abstract

Proposed is a three-dimensional skeleton generation method using calibration based on a joint acquired from a multiview camera, capable of extracting a partial skeleton of each viewpoint from a distributed RGB-D camera, calculating a camera parameter by using a joint of each partial skeleton as a feature point, and integrating each partial skeleton into a three-dimensional skeleton based on the parameter. The three-dimensional skeleton generation method includes: (a) acquiring a multiview color-depth video; (b) generating a three-dimensional skeleton of each viewpoint from a color-depth video of each viewpoint, and generating a joint of the skeleton of each viewpoint as a feature point; (c) performing extrinsic calibration for optimizing an extrinsic parameter by using the joint of the skeleton of each viewpoint; and (d) aligning and integrating the three-dimensional skeleton of each viewpoint by using the extrinsic parameter.
