Image Stitching Algorithm of Digital Camera with Single Field Lens and Multiple Area CCD

According to the geometric imaging principle of new type area mapping camera constructed by multi CCD in single field-of-view,the basic method of image geometric processing is proposed for surveying and mapping application.Based on the nature of combined area camera,the digital image error is proposed,which includes the errors of focal length,principle point coordinate and optical distort etc,and the error of the size of area CCD and the camera assembly are considered,and the camera self-calibration is done by bundle adjustment,the effect of the quality on surveying and mapping can be deceased.The method is tested by aerial photogrammtry in Hanzhong field,and the effectiveness of the proposed method is validated by the test result.
