基于计算机视觉的目标方位测量方法
Target Azimuth Measuring Method Based on Computer Vision
摘要
Abstract
Aiming at key point of obvious marker,an azimuth measuring method for targets based on computer vision system is investigated.According to the principle of projection imaging,the mapping relationship between the 3D position and the 2D image of the target is derived,and the target azimuth measuring mathematical model is established based on monocular vision system.Lens distortion has been taken into account during the implement of Zhang’s calibration method. Harris corner detector is brought to find the most characteristic corners on 2D image,and the sub-pixel orientation method is applied to the positioning of target feature points.The experimental results show that the method can effectively extract the target feature points and get its pixel coordinates,acquiring a relatively accurate target azimuth,which has good application value.关键词
