VisualSFM generated models separately in the process, although the process stopped, all finished point clouds can be found in the computation folder. The AscTec Falcon 8 collects photos with a resolution of 6000*4000. In CMVS reconstruction, an exponential relation exists between time and the resolution of the photos (proved in Figure 34: CMVS time costing for images with different resolutions). Therefore when the dataset was computed with its original resolution, the processing time is extremely long. After 5404.083 minutes, VisualSFM had stopped. When the resolution of the photos was reduced to 3000*2000, the processing time had dropped down to 24.7 minutes.
