AUTOMATED EXTRACTION OF FEATURES FROM CAD MODELS FOR 3D OBJECT RECOGNITION
Object recognition CAD Modeling Feature extraction
2015/1/7
In this paper we report on our work on a CAD model-based object recognition system for industrial parts. We present a novel approach which uses information derived from the CAD model in the early proc...
CONSTRAINTS IN CAD MODELS FOR REVERSE ENGINEERING USING PHOTOGRAMMETRY
CAD Modeling Photogrammetry Reconstruction
2015/1/6
The paper discusses the use of geometric constraints in a CAD model-based photogrammetric system. The CAD models are represented by CSG (Constructive Solid Geometry) models. The geometric primitives t...
RECONSTRUCTION OF CONSISTENT 3D CAD MODELS FROM POINT CLOUD DATA USING A PRIORI CAD MODELS
Industrial Plants Modeling Point Cloud CAD Model Reverse Engineering Bayesian Reconstruction
2014/6/5
We address the reconstruction of 3D CAD models from point cloud data acquired in industrial environments, using a pre-existing 3D model as an initial estimate of the scene to be processed. Indeed, thi...
