| Abstract: | 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. |
