| Abstract: | In construction of hydroelectric project, small range DTM data are often needed for topographic surveying, mapping, excavated form detection, earthwork calculation and so on. Aimed at overcoming the shortage of DTM data collection working mode, this paper deals with the measurement and alteration of ordinary digital camera, the twin photos orientation of ordinary digital image and the method of DTM data collecting automatically. Based on that, DTM data collection system is developed, which makes the rapid collection possible, and has been proved very useful in practice. |
