| Abstract: | To the dim and small target detection and recognition of the coordinate measurement system,some methods were presented to increase the system acquirement rate.Based on the images and target characteristics,by improving the quality of background image,distinguishing target imaging characteristics and setting time window,recognition and intersection data was got.A higher acquirement rate of the system was obtained by counter-computing these data to increase the ability of the dim and small target detection an... |
