摘要
双目立体视觉测距系统由于计算量大、受限于硬件水平等原因,通常无法做到实时测距,为解决这一问题,对双目立体视觉的关键技术进行研究与分析后,采用预标定方法,通过选取一种快速的立体匹配算法,对其各参数进行优化,并以动态视差搜索的方式,结合目标跟踪算法,实现了对目标的实时跟踪与测量。经实验验证,该系统成本低、可行性高,能实时对目标进行跟踪与测量,并在一定范围内具有较高的精度,且有一定的应用价值。
Real-time distance measurement is often unavailable in a stereo vision measurement system because of large amount of calculation and hardware limitation. In this paper, the key technologies of binocular stereo vision are introduced. The method of pre-calibration is used along with a fast stereo matching algorithm and optimized parameters to achieve the target real time tracking and measurement by the dynamic disparity search combined with the target tracking algorithm. Experiments indicate the low cost system has high feasibility and achieves real-time track- ing and measurement of object with precision in a certain range.
