動作擷取可被用來做電腦動畫與虛擬實境的設計,並應用在影片、娛樂、遊戲、訓練、醫學開刀與教育,因此最近各種的動作擷取方法的研究,被廣泛的提出與討論。本計畫提出一全新設計的動作擷取系統,該系統使用一線性超寬頻( UWB )陣列天線作發射,另一單根天線作接收。陣列天線最外兩根天線是用來做快速初始位置的粗略佮計,一旦位置估計確定即進入行動追蹤階段。整組線性陣列天線被用來產生發射UWB信號的波束合成波,並聚焦到欲追蹤之點o波束被電子式的操控去追蹤與分辨移動部位的變化。其中我們提出的一種空時信號處理的方法,並推導設計其數學與運算模式,此架構可使用Sy s t em View 與Matlab Simulink 軟體去模擬其有效性與性能, 將於未來討言侖o
Motion capture research has been addressed widely recently due to it can be applied to computer animation and virtual reality design for various purposes such as filming, entertainment, training, medical surgery and education. In this paper we deal with the computational feasibility study of a newly designed motion capture system using a linear UWB impulse phase array. The system consists of a linear transmit phase array antenna and a single receive antenna. The strategy is to first use the outer two antennas of the array for the initial fast coarse location estimate then follows by motion tracking using entire array. While in the locationing process, the outer two antennas simply act as two omni antennas. No beamforming strategy is used. Once the coarse location has been estimated the system enters into the motion tracking phase, and an active transmit space-time beamforming by the entire phase array antenna is used. The beam is electronically steered to the desired spots (directions and ranges) by the previous location estimate from the system. This is then served as the next estimate set up and operates recursively before it converges. We propose only the a space-time processing methodology for implementing the particular transmit beamforming. The designed system can be simulated by the System View and Matlab Simulink easily to test the availability and performance and will be addressed later .
