Abstract:

Auto-focus technology is a way to enhance the measurement accuracy.The article describes the application of automatic focusing method based on image processing in airborne electro-optical imaging device.The two focusing evaluation operators of Mix and Bevel are proposed.Three focus control strategies are employed,namely the local global search method,AC variable-length climbing search method and a combination of the two.Experiments show that the auto-focus image processing meets the requirements of the focusing accuracy of airborne electro-optical imaging devices.

Key words: Image processing;automatic focusing;airborne electro-optical imaging
