【摘要】 地平式光电成像跟踪测量设备进行目标观测时,由于物像空间旋转而产生像旋,使目标提取和测量出错。为消除像旋,先建立了以球面三角和坐标变换为基础的像旋模型,对像旋模型中各个变量的关系进行了分析,并简介了目前几种常用的消像旋的方法,提出一种采用CCD相机旋转消像旋的设计思路,详细地描述了消像旋指标、单元结构和控制流程的设计过程,并在某光测设备上实现应用。厂内检测数据和在外场运行试验结果证明,采用CCD相机旋转消像旋的设计达到设计指标,满足设计要求,保证了光电跟踪测量设备对目标的准确提取和稳定跟踪。更多还原

【Abstract】 The imaging rotation problem occurred because of the rotation between the object and the imaging space when altitude-azimuth opto-electronic imaging tracking and measuring device observed a target.It made the target extraction and measuring failure.So an imaging rotation model was structured based on the theory of spherical trigonometry and coordinates transformation,the relationship between variables of this model was analyzed,several methods of eliminating image rotation were listed,and a design of CCD camera rotation was adopted to eliminate image rotation.The performance index,structure and control process of this unit were described specifically.This design has been applied on an opto-electronic imaging tracking and measuring device.The factory test and outfield trial results proves that the design of eliminating image rotation with CCD camera rotation satisfies the demand of project,and it ensures that the tracking and measuring device can extract and track targets truly and stably.更多还原
