A Method for 3D Scene Description and Segmentation in an Object Record
ChenTingbiao · 中国邮电高校学报：英文版 · 1996
In this paper a novel data-and rule-driven system for 3D scene description and segmentation in an unknown environment is presented.This system generates hierachies of features that correspond to structural elements such as boundaries and shape classes of individual object as well as relationships between objects.It is implemented as an added high-level component to an existing low-level binocular vision system^[1].Based on a pair of matched stereo images produced by that system,3D segmentation is first performed to group object boundary data into several edge-sets,each of which is believed to belong to a particular object.The gross features of each object are extracted and stored in an object record.The final structural description of the scene is accomplished with information in the object record,a set of rules and a rule implementor.The system is designed to handle partially occluded objects of different shapes and sizes on the 2D images.Experimental results have shown its success in computing both object and structural level descriptions of common man-made objects.
