飞机调姿测量点的激光跟踪仪可视化定位

Laser Tracker Visual Positioning of Posture Measuring Point

飞机部件装配过程中调姿测量点的可视化定位是实现飞机自动化装配的重要部分。可视化定位系统是由高清摄像头和激光跟踪仪两部分组成。本设计基于OpenCV软件对摄像头采集的视频流进行图像处理,在摄像头视野中自动搜寻目标靶点位置信息,对目标点进行交互式选定。再经过图像处理过程提取出激光光斑,得到光斑像素坐标,由激光跟踪仪进行激光的跟踪控制,采用逐次逼近算法将激光点跟踪到目标点。

Visual positioning of posture measuring point is important for plane automatic assembly in the assembly process of aircraft parts. The visual positioning system is made of high definition camera and laser tracking device. Here, a target visual positioning system is designed based on open computer vision （OpenCV）, which can image processing with video streaming collected by camera. The system searches target automatically in the vision field of camera and selects the target interactively and manually. And then a laser tracker controls the offset of the laser, and makes the laser point track to the target by the successive approximation algorithm.
