摘要
论文在研究平面标靶合作标识的精确识别算法和图形空间向量变换模型基础上,建立了空间姿态测量算法模型与软件流程,并提出了一种新的拓扑定位方法,并以模拟汽车四轮定位视觉测量为例进行验证,结果表明该方法具有较好的抗遮挡能力,较宽的测量范围和较高的测量精度,为采用平面靶标组建的机器视觉测量系统提供了一种可行的方法。
On the basis of studying the accurately identification algorithm of planar target and transformation model of the space vector,the imaging target models and spatial attitude measurement models are established.Then,a new topological positioning method is put forward.Finally,the four-wheel location measurement is given as an example.The results demonstrate that the method has better anti-interference and higher measurement precision,which provides a feasible method for a machine vision measurement system by using the plane target.
