Abstract

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.
