Application of Superresolution Technology in Non-contact Measurement on Edge Detection of Precise Parts

摘要：

The precision of traditional methods of edge detection of precise Parts with linear CCD only reach μm because of the size of CCD cells. A sup-pixel edge detection method of CCD based on least square method and derivative operator method is proposed to improve the measurement precision. The Image Gradient obtained using derivative operator method. Point A with the max Gradient is then regarded as the point of the edge, and then the pixels nearby edge are interpolated linearly. For example, a high-speed data acquisition system is designed using high accuracy linear CCD TCD1501D and high speed A/D converter TLC5510.Experimental results show that the resolution μ of the system design is 0.02pixel and the measurement precision is improved by one order of magnitude over traditional methods of edge detection.
