Realization of the Imaging-Auto-Focus on the APRC Using Splicing-CCD

摘要：

It is difficult to deal with the auto-focus of aerial push-broom remote sensing camera (APRC) based on image processing. First of all, this paper recommended the Splicing structure of CCD in the APRC Based on this, auto-focus method which is made use of the overlapping area of CCD mosaic structure was proposed, combined with the characteristic of the imaging mode. After analyzing of experiments about all kinds of focus-examine functions based on image processing, the gradient square function has been chosen. The experimental results show that the proposed autofocus method for the APRC is proved to be feasible and realtime.
