| 英文摘要 | In order to solve the problem of automatic focus plane detection in aerial remote camera, a new method of automatic focus plane detection for aerial remote camera used Visibility based on SFV technique was proposed. Firstly, in the process of focusing, spatial filtering characteristic of spatial slits was simulated by doing interval sample with linear CCD image, the best focus position was found by searching maxim Visibility value of SFV signal, through used relationship between SFV signal and the Visibility value. Secondly, spatial filtering velocimetry and relationship of Visibility and defocusing error was introduced, and experiment setup was designed. Lastly, for the typical image motion velocity between 5 mm/s to 53.2 mm/s, 20 times focal plane detection tests were taken, and the experiment results show that the focusing accuracy was higher than 46.25m, which was within the tolerant defocus (76.8m) and satisfies requirement of aerial remote camera. 2019, Editorial Board of Journal of Infrared and Laser Engineering.
