摘要
立体视觉是被动式测距的一种重要方法,而立体匹配则是整个体视算法中最重要也是最困难的部分。计算复杂度高,算法的实时性难以保证是立体匹配算法中的一个突出问题。针对基于高性能DSP的立体匹配实时性问题展开研究,提出了一种基于TMS320C64x的实时立体视觉算法。实验结果表明,提出的算法能够充分利用C64xDSP的架构特性,具有实时性高(大于每秒30帧),结果准确的优点。
Stereo vision is one of the most important methods to measure the distance passively. This paper presents a real-time stereo matching algorithm based on TMS320C64x DSP processor. Optimization is executed in two stages: first, good mapping between the stereo matching algorithm and DSP architecture is achieved by the well designed algorithm; then special turning according to the functional unit is performed. Experimental results show that the proposed method is effective, which can achieve more than 30 freme/s for a 384×288 stereo pair.
