Two-frequency phase-shifting phase unwrap** and Gray-coded-based phase unwrap**
are two typical temporal phase unwrap** methods to recover discontinuous or spatially …

We present a structured lighting system for creating high-resolution stereo datasets of static
indoor scenes with highly accurate ground-truth disparities. The system includes novel …

Vision-based three-dimensional (3D) shape measurement techniques have been widely
applied over the past decades in numerous applications due to their characteristics of high …

Time of flight cameras produce real-time range maps at a relatively low cost using
continuous wave amplitude modulation and demodulation. However, they are geared to …

Dimensional measurements play a central role in enabling advanced manufacturing
technologies, enhancing the quality of products and increasing productivity. This role …

In correlation-based time-of-flight (C-ToF) imaging systems, light sources with temporally
varying intensities illuminate the scene. Due to global illumination, the temporally varying …

The aim of this study is to gain basic information about matte coating thickness in the area of
3D optical digitization. Thickness measurement was performed for two matting materials; …

We propose to recover spectral details from RGB images of known spectral quantization by
modeling natural spectra under Gaussian Processes and combining them with the RGB …

Structured light 3D scanning systems are fundamentally constrained by limited sensor
bandwidth and light source power, hindering their performance in real-world applications …

Continuous-wave Time-of-flight (TOF) range imaging has become a commercially viable
technology with many applications in computer vision and graphics. However, the depth …
