Abstract:
For surface reconstruction using motion, objects are placed on a rotating disc in front of a single camera. For camera calibration the method by Tsai was implemented, extended (calculation of distorted from undisturbed coordinates) and optimized (e.g. with respect to the number of calibration planes and points in each plane) (1). The way the calibration results can be used for this special case of surface reconstruction of objects on a rotating disc is described. Motion vectors calculated from point correspondences are used as input for this calculation of 3-D point positions. In two theorems, new reconstruction formulae are given. Experimentally, accurate depth values could be obtained for sparse object surface points. It is suggested to combine these exact values with ßurface drafts” calculated by approaches based on reflectance properties. © 1995 Academic Press. All rights reserved.
