| Abstract: | The focus of High-speed Measurement TV is how to carry out focusing effectively and quickly.An automatic focusing system based on digital image processing is proposed.The sum of edge points of an image is used as the criterion function of whether the image is focused.The hill-climbing automatic focusing principle with adaptive searching step size is also given.The experiments are carried out with system and the results and the focused images are given. |
