Two Methods of Improving the Focus Survey Precision Based on CCD Camera

摘要：

　　The principium of measuring focus of aerial camera and the location of the actual image plane with CCD camera are introduced,and the methods to improve survey precision are described.The image is received by area CCD camera.The accuracy of orientation of the imaging central line is improved by means of fit the curve method or by center of gravity method.Therefore,the distance between imaging central lines is refinedly calculated.The experimented turn out that the two methods on measuring focus of aerial camera have high precision,and the survey errors are in accordance with the theoretical ones(0.12%).The two methods on deterministic result of the location of the actual image plane are identical,with their precision reaching 100%.
