Two Dimensional Phase Unwrapping Theory Algorithms And Software

This paper analyzes the phase error for a 3-D shape measurement system that utilizes our recently proposed projector defocusing
technique. In this technique, by defocusing binary structured patterns, seemingly sinusoidal ones can be generated,
and 3-D shape measurement can be performed by fringe analysis. However, there are still significant errors if the object
is not within a certain depth range where the defocused fringe patterns still have binary structures. In this research, we
experimentally studied a large depth range of defocused fringe patterns, from close to be binary to to be sinusoidal, and its
associated phase errors are analyzed. We established a mathematical phase error function in terms of the wrapped phase
and the depth z. Finally, the mathematical function is calibrated and is used to compensate for the phase error at arbitrary
depth ranges within the calibration volume. Experiment will be presented to demonstrate the success of this proposed
technique.

Error analysis for 3D shape measurement with projector defocusing

We give the topology changing of the silhouette in 3D space while others study the projections in an image. Silhouettes play a crucial role in visualization, graphics and vision. This work focuses on the global behaviors of silhouettes, especially their topological evolutions, such as splitting, merging, appearing and disappearing. The dynamics of silhouettes are governed by the topology, the curvature of the surface, and the view point. In this paper, we work on a more theoretical level to give enumerative properties of the silhouette including: the integration of signed geodesic curvature along a silhouette is equal to the view cone angle; in elliptic regions, no silhouette can be contained in another one; in hyperbolic regions, if a silhouette is homotopic to a point, then it has at least 4 cusps; finally, critical events can only happen when the view point is on the aspect surfaces (ruled surface of the asymptotic lines of parabolic points with surface itself). We also introduce a method to visualize the evolution of silhouettes, especially all the critical events where the topologies of the silhouettes change. The results have broad applications in computer vision for recognition, graphics for rendering and visualization.

Topology evolutions of silhouettes

Zero phase line is extremely important for precision measurement especially for calibrations since zero phase line is usually used as reference point for 3D reconstruction. However, the existing dithering technique often has difficult to maintain this phase line when the projector is at different defocusing amounts. In this paper, we will propose a dithered optimization method that will overcome this difficulty. Mathematical proof as well as simulation data will be presented to verify the success of the proposed method.

Zero-phase locking for phase-shifted dithering techniques

This paper intends to thoroughly evaluate the influences of different phase-shifting algorithms, and optimization directions, and initial patterns. For fair comparisons, we used the same number of iterations for optimization and the same size of optimization patches. The variables are optimization domain (i.e., phase and intensity domain), the step number of the phase-shifting algorithm (i.e.. three and four step), the initial pattern (i.e., Bayer dithered and error diffusion dithered pattern), and the optimization direction (i.e., top to bottom, bottom to top, left to right, and right to left). Our ultimate goal is to generate the best possible quality binary pattern after optimization and hopefully provides guidelines on optimization strategies. Our simulation results suggest that an exhaustive optimization is necessary in order to produce the best quality pattern.

Optimizing binary dithering patterns to improve phase quality

We developed a novel method based on geometry to reconstruct a dynamic face solely by using the conventional structured light system, which does not need extra images, hardware components, or objects. In our method, the bridge of the nose is considered the feature region because its shape remains almost constant when a human is moving or making expressions. This three-dimensional (3D) face reconstruction method consists of the following steps: (1) spatially unwrap the phase and obtain the texture image for each frame; (2) locate the nose area for each frame with a feature detection algorithm; (3) determine the fringe order in the first frame with the cues given by traditional methods and acquire the recovered result of the feature region; (4) locate the feature region for each possible fringe order in one frame by finding the pixel nearest to the camera along the depth direction in the nose area; (5) register each 3D shape of the feature region with it in the former frame by the Iterative Closest Point (ICP) algorithm; (6) determine the fringe order by the minimal Hausdorff distance between two registered 3D shapes and then construct the face with the entire absolute phase map. Experimental results indicate that our proposed approach is capable of real-time reconstruction of a dynamic face and only three phase-shifted fringes are required per frame.
