【摘要】 焦面上的成像质量分析是红外导引头测试的重要内容。图像处理是自动聚焦前必需完成的重要工作,而调焦函数的选取是自动聚焦的关键技术。本文介绍了光斑图像处理的方法及常用聚焦算法的原理。聚焦的控制流程采用传统的登山随动自动搜索法,由于VISUAL C++的实时性不够理想,本试验结合实际编制合理可靠的算法,提高聚焦速度且能达到较高的精度和重复性,获得了理想的效果。更多还原

【Abstract】 The analysis of the image quality on focus plate is very important in infrared seeker measurement. As for auto-focusing system, image manipulation is critical preparation, and choosing focusing function is the core technology. How to process image and the widely-used principle of various focus arithmetic is discussed. Traditional climbing real-time searching is improved in practical application because Visual C++ is not good enough in controlling. In this way, higher speed, precision and repetition are accomplished.更多还原
