摘要
CCD的分辨率是影响新型光电自准直仪测量精度的关键因素,而边缘检测法是CCD位移测量的主要方 法。对数字图像处理中直线拟合边缘检测法进行了详细介绍,并将其应用于高精度一维光电自准直仪的研制。
The resolution of CCD is the key factor that impacts the measurement precision of new-type photoelectric autocollimator. Edge detection is the main method for CCD displacement measurement. The edge detection method with straight line fitting in digital image processing has been introduced in detail in this paper, and it has been applied into the development of high precision one-dimension photoelectric autocollimator.
