Abstract: The objective of this research is to point out the deficiency of the modeling from a single image and give suggestion for the improvement. In the domain of cultural heritage visualization, single image modeling is mainly used to recover the scene shown in the historical photographs. In this paper, some common ambiguities in the area of the historical architectural environments are highlighted. In most approaches user is the one to introduce and choose constraints, and therefore he must have control over the ambiguity problems. We propose suggestions about how to adjust the single-image-based modeling in order to minimize chance for irregular 3D shapes to emerge due to ambiguity. Simple examples are used to illustrate how ambiguity of a single image can affect the models veridicality, which are the common mistakes that inexperienced user can make and how and when they can be corrected.
