On the Eualuation and Analysis of Image Quality of Rmall Rcale Negatives with Forward Motion Compensation

In working out flight planning ot small scale serial photographs for the revision topogprahic maps at the scale of 1:50000,it is quite important to Consider with one is a main facter effecting on the quality of small scale aerial photographs and its measuring performance,either image forward motion or film characteristics.In view of this proklem,the test of image quality analysis and the comparsion of measuring pfrformance were carried out using two kinds of film with different resolution and three photograph scale among them the Forward Motion Compensation Camera has been used for the film of high resolution.Based on the enalysis of experiments it has bee shown that,the main factor effecting on the quality of photograph at scalas of 1:50000 and 1:80000 is the macro-characterisfic of film,and the effects of FMC on image quality could be omited.
