Researches on the reconstruction of solid objects from multiple views are turning their attention to the ambiguities of constructed objects and restoration from views with abbreviations. We develop a new method which accepts inconsistent views and estimates solid objects with curved surfaces. The sources of inconsistencies are missing segments, extra segments and improper designations of visible lines or hidden lines. The reconstruction process of solid objects uses a hybrid method: a B-Reps method which makes polyhedron from straight segments in views and a CSG method which makes curved surfaces from arc segments in views. We have already proposed our method which identifies inconsistencies in views with straight segments and gives estimated solid objects. In this paper, we investigate the restoration of CSG primitives with curved surfaces, classify the inconsistencies found during the reconstruction process of primitives and present a way to estimate solid objects.
