针对用于目标定位的复眼雏形？簇眼,提出一种标定多通道成像畸变的方案。该方法根据目标定位和多通道同时标定的数学模型,首先,通过引入分光器,调整目标平面水平移动轴和目标平面的垂直性以及目标平面和簇眼平面之间的平行性;然后,使用消逝点、目标共像点的方法求得初始点和初始距离后,得到目标平面上每一点的空间三维坐标;最后,求出目标阵列与对应通道的入射角度,提取出对应的目标像点重心后,建立各通道入射角度和像点重心之间的对应关系。实验结果显示此方案能满足簇眼成像非线性标定的要求,初步标定后的系统目标角度分辨率可达0.02°,距离定位精度可以控制在3%以内。

英文摘要：

Aiming for the cluster eyes,as the rudiment of compound eye,the scheme for calibrating multichannel imaging distortion was presented for target positioning.According to the mathematical models of positioning target and multichannel calibration,by the optical splitter,the verticality between horizontal movement axle of target plane and target plane and the parallelity between target plane and cluster eyes plane were adjusted firstly.After the methods of vanishing points and the common imaging point of different points on the Y-axis were used to obtain initial point and distance,three-dimensional coordinate of every point located on the target plane could be obtained.Finally,after getting the angle between every target and corresponding channels and its imaging center,the corresponding relation between angle of each channel and the imaging center was established.The experimental results show that the scheme can meet the requirement for nonlinear calibration of cluster eyes,and the calibrated angle resolution initially could reach 0.02° and the distance precision for target positioning could be controlled within less than 3%.
