Human upper body posture recognition and upper limbs motion parameters estimation
Junyang Huang, Shih-Chung Hsu, Chung‐Lin Huang · 2013
We propose a real-time human motion capturing system to estimate the upper body motion parameters consisting of the positions of upper limb joints based on the depth images captured by using Kinect. The system consists of the action type classifier and the body part classifiers. For each action type, we have a body part classifier which segment the depth map into 16 different body parts of which the centroids can be linked to represent the human body skeleton. Finally, we exploit the temporal relationship between of each body part to correct the occlusion problem and determine the occluded depth information of the occluded body parts. In the experiments, we show that by using Kinect our system can estimate upper limb motion parameters of a human object in real-time effectively.
