高精度角度自动测量系统采用自准直平行光管将被测角度转换为焦平面上两十字叉丝的相对位移，经ＣＣＤ摄像机和图像采集卡对叉丝图像采集后进入计算机进行识别和处理，并根据图像的特点采用两次拟合的算法得到高精度的角度值。高精度角度自动测量系统具有测量精度高、自动化程度高、稳定性好、适应性强、可同时进行二维角度测量等特点。系统角度测量分辨率达０－０１″，测量精度为０－１″
High-precision automatic angle measurement system uses self-collimating parallel light pipe to convert the measured angle to the relative displacement of the two cross wires on the focal plane. The CCD camera and the image acquisition card collect the cross-hatch image and then enter the computer to identify and process. According to the characteristics of the image, the algorithm of twice fitting is used to obtain the high-precision angle value. High-precision automatic angle measurement system with high accuracy, high degree of automation, good stability, adaptability, can be two-dimensional angle measurement and so on. System angle measurement resolution of 0-01 “, measurement accuracy of 0-1”
