| 摘 要： | 对基于光电准直和针孔成像原理的姿态角测量系统,提出一种虚拟扩展成像面技术,对图像传感器成像面进行复用,虚拟扩大系统的测量视场.基于反射不对称的针孔光阑设计,实现一种光斑模式识别方法,对光斑质心和正反射模式进行识别,并进行虚拟成像面坐标扩展.通过计算机仿真,对识别结果进行了分析验证,表明这种方法对各种光斑模式都能准确识别,成倍扩大了测量视场.

| Abstract: | Virtual extension imaging was proposed to apply to large field of view(FOV) attitude angle measurement based on photoelectric collimation and pinhole imaging theory.The FOV was virtually enlarged through multi-imaging.Based on the designed anisomerous pinhole diaphragm,an identify method for spot pattern was proposed to judge whether the spot was reflected or not,and to map the spot coordinate to expanded imaging surface.The identify result was analyzed and verified via the computer simulation.The results s... |
