Anti-shielding hand key node tracking method

Abstract

The invention discloses an anti-shielding hand key node tracking method. The method comprises: a panoramic camera is constructed and calibrated, a large number of hand attitude image samples are obtained, the image samples are inputted into a convolutional neural network for image pooling convolutional processing, so that the convolutional neural network is trained and is iteratively optimized; and a common camera captures real-time image information of shielded hand key nodes, real-time image identification is carried out on the trained convolutional neural network after iterative optimization, and dotted line images of hand key nodes and hand skeleton are outputted. According to the invention, the shielded images are captured in real time by the common camera and the shielded hand key nodes are identified and tracked by using the convolutional neural network after iterative optimization. Therefore, a defect that the shielded hand key nodes can not be identified and tracked in the prior art is overcome; and thus the shielded hand key nodes can be identified and tracked in a shielded state.
