Algorithms for Constructing 3-D Point Clouds Using Multiple Digital Fringe Projection Patterns
This paper describes algorithms for generating 3-D point clouds from a set of digital images obtained from projecting phase-shifted sinusoidal fringe patterns onto object. In this paper, a mathematical model is introduced for describing the geometric relationship between the fringe patterns being projected, the image captured and the shape of the object being measured. This model allows conside...

متن کاملModel and Algorithms for Point Cloud Construction Using Digital Projection Patterns
This paper describes a computational framework for constructing point clouds using digital projection patterns. The basic principle behind the approach is to project known patterns on the object using a digital projector. A digital camera is then used to take images of the object with the known projection patterns imposed on it. Due to the presence of 3-D faces of the object, the projection pat...
متن کاملAlgorithms for Generating Adaptive Projection Patterns for 3-D Shape Measurement
Point cloud construction using digital fringe projection (PCCDFP) is a non-contact technique for acquiring dense point clouds to represent the 3-D shapes of objects. Most existing PCCDFP systems use projection patterns consisting of straight fringes with fixed fringe pitches. In certain situations, such patterns do not give the best results. In our earlier work, we have shown that for surfaces ...
