基于单目视觉的距离测量研究

针对目前单目视觉中依靠图像标定及其在双目视觉中立体匹配方法的不足,提出了利用单目视觉测量物体与镜头之间距离的测距方法。首先利用步进电机控制镜头移动来引起图像放大倍数的变化,然后根据图像的放大倍数和镜头移动的距离来计算镜头与物体之间的距离,距离计算的准确性已通过测量试验得到验证。

Study on Distance Measurement Based on Monocular Vision Technique

To solve the defects of depending on image demarcation existed in current monocular vision and in the tridimensional match of the binocular vision, an approach of using monocular vision to measure the distance between an object and the lens is put forward in the paper. In this approach, a stepping motor is firstly used to control lens movement for causing the change of scale ratio of an image, then, the distance between the lens and the object is calculated according to the scale ratio and the moving distance of the lens. Forever, the exactness of the calculated distance is verified through measurements.
