One way is to combine aerial photos with ground photos. Photos from “Region A” (shown in Figure 69) were combined with 80 aerial photos from the UAV dataset. CMPMVS was used for the implementation. The result shows that combining ground photos with aerial photos will not increase detailed information dramatically. Figure 81 gives a comparison between a model from ground photos and a model which is generated from a combination of ground photos and aerial photos. The result is very clear: in CMPMVS workflow, by using a combination of ground photos and aerial photos will not increase the level of detail on specific regions. The reason was described in section 4.1. CMPMVS surface reconstruction process is similar to the process in PhotoScan, the program needs a local coordinate system as a platform, and on this platform meshes will be created.
