Abstract: An accuracy comparison research was conducted between the incremental structure from motion in computer vision and the POS-aided bundle adjustment in photogrammetry. Firstly, the basic principle and workflow of SFM were introduced, and the similarities and differences between the two methods were analyzed theoretically. Then the positioning accuracy was compared, using the unmanned helicopter and manned aircraft aerial survey data in the Songshan remote sensing calibration field. Experimental results show that without POS data, the incremental structure from motion method can achieve equivalent accuracy to the POS-aided bundle adjustment. Both methods can meet the requirement of 1:500 and 1:1000 mapping. Finally, suggestion was proposed for aerial data post-processing according to different operational requirements.

Key words: incremental structure from motion, bundle adjustment, accuracy, comparison
