The rapid growing of somatosensory interaction technique is becoming a new and strong momentum for the development of computer graphics applications. The final reconstructed mesh model demonstrates good fidelity against the person with personalized details of hairstyle, face, and salient cloth wrinkles. The missing gaps between the front and back scans are filled using quadratic Bézier curve. Since all these partial scans can be captured in a moment, the discrepancy between them caused by body movement is neglectable, saving the effort of non-rigid alignment. After denoising, all partial scans are rigidly aligned together using a novel supersymmetric third-order graph matching algorithm. To alleviate the view angle limit, the two Kinects are driven by their automatic motors to capture three scans covering the upper, middle and lower part of the person from front and back respectively, resulting in three partial scans for each Kinect. This fast capture is achieved by using two calibrated Kinects to capture the front and back side of the person simultaneously. The key feature of the system is that the capturing process can be finished in a moment, or quantitatively 3 s, which is short enough for the person being captured to hold a static pose stably and comfortably. We present a system for fast capture of personalized 3D avatar using two Kinects.
