Abstract
Automatic measuring of image information recorded on high-speed 35 mm photography film is realized by a measuring system with adoption of 2D Charge Coupled Device (CCD) array as an image sensor and in connection with optics, precision mechanics, electronics, image processing and computer technology. The pixel numbers of CCD image sensor are 1300 X 1000, the pixel size is 6.8 micrometers X 6.8 micrometers and the pixel resolution is 19 micrometers . The system also has semiautomatic reading mode. The automatic and semiautomatic mode can be interchanged. The measuring accuracy of 2D coordinates is within 15 micrometers and the measuring speed is 2 f/s approximately equals 3 f/s.
