摘要

摘要: 介绍了航空成像系统的特殊工作环境及应用需求对检调焦技术的要求，讨论了当前3种主要检调焦方法：程序标定法，光学自准直法及图像对比度法，总结并比较了3种方法的检调焦精度、检调焦时间等性能指标。最后着重讨论了基于光场成像理论与光学系统离焦深度之间的关系，对基于光场成像原理的快速检调焦技术进行了深入的分析、讨论，并对该技术在航空成像系统的应用前景进行了展望分析。

Abstract: The requirements of auto-focusing technique for the aerial remote sensing system are introduced considering the unique operating conditions and the applications, and three major auto-focusing techniques, namely programming focusing technique, auto-collimation focusing technique and the image contrast focusing technique, are analysed. Furthermore, the performance indexes such as focusing precision, focusing timing consumption as well as application limitation of these three techniques are discussed. Finally, we focus on the relationship between the light field theory and the auto-focusing technique, and its further application prospect in the aerial camera system is also analyzed.
