Abstract:To meet the needs of the intersection accuracy and images automatic matching, and based on the fact that angle of view of current aerial digital camera is small in flight direction, the paper discusses the necessity and significance of photogrammetry based on high overlap images and Multi- Baseline. The method of normal case photography and convergent photography based on Multi - Baseline with non - metric camera is discussed emphatically, and the characteristic of the data processing by this method is also introduced. In particular, through the experiments with different no- metric cameras on Tail Water Slop of Three Gorges Underground Power Station, it is proved that convergent photography based on Multi- Baseline has acquired the very approving accuracy that is difficult to be acquired by conventional no- metric camera.
