摘要:

自动调焦技术是一种可提升测量精度的方法。文中介绍了基于图像处理的自动调焦方式在机载光电成像设备中的应用。提出了Mix算子和Bevel算子两种调焦评价算子方式。应用局部全局搜索法、交变长爬山搜索法以及综合搜索法3种调焦控制策略。通过实验表明,采用图像处理自动调焦方式能满足机载光电成像设备调焦精确性要求。

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
