PHOTOGRAMMETRIC SYSTEM AND TECHNIQUES FOR 3D ACQUISITION
摘要
A photogrammetric system and techniques applicable to photogrammetric systems in general are provided. The system provides the choice between the various types of light projection on the object to be measured and methods for retrieving 3D points on the object using a pattern projection method, a coded light method, and/or a method using intrinsic features of the object or a combination of such methods. A first technique provides camera position approximation using known distances between features. A second technique provides image processing parameters that take into account the local distance and orientation of the object to measured. A third technique provides the 3D correction of the position of the center of a sphere when imaging a spherical object.
