%X In the close range photogrammetry , the quality of the generated digital surface model is controlled by some course parameters . This paper discuss these parameters from technique method , band choice and fusion , image correlation parameter , analysis their influence to the quality of output DEM , and present the experienced way of the choice of these parameters. Using two different technique: Block or Stereo, the number of correlation points is near, but the quality of the result is different , the result of Stereo is better. There are many bands can be used, but only one is needed in the image correlation. To the different color band , Red and Green seem to have good result, the Red band is better. The fusion band , such as intensity band or the first principle band , can increase the correlation points. At the image correlation course, the correlation template size is sensible to In some range, increasing the template size can increase the number of correlation point. The larger template range , the larger number of correlation points. But at the same time, the error area appears seriously. To resolve this problem, using rejection factor, maximum parallax and skip factor can get a better result image.
