High-resolution, high-speed three-dimensional shape measurement using projector defocusing
Yuanzheng Gong Song Zhang Iowa State University Department of Mechanical Engineering Ames, Iowa 50011 E-mail: [email protected] Abstract. We present a high-resolution, high-speed three-dimensional (3-D) shape measurement technique that can reach the speed limit of a digital fringe projection system without significantly increasing the system cost. Instead of generating sinusoidal fringe patterns...
متن کاملGenerating sinusoidal fringe by defocusing: potentials for unprecedentedly high-speed 3-D shape measurement using a DLP projector
This paper presents a technique that reaches 3-D shape measurement speed beyond the digital-light-processing (DLP) projector’s projection speed. For this technique, a “solid-state” binary structured pattern is generated with each micromirror pixel always being at one status (ON or OFF). By this means, any time segment of projection can represent the whole signal, thus the exposure time can be s...
متن کاملFlexible 3D shape measurement using projector defocusing: extended measurement range.
A recently proposed flexible 3D shape measurement technique using a defocused projector [Opt. Lett. 34, 3080 (2009)] shows great potential because of its elimination of projector's gamma calibration. However, it cannot handle step-height surfaces. I present here a technique to extend its measurement range to an arbitrary shape by integrating a binary coding method. A computational framework is ...
متن کاملA high speed programmable focal-plane SIMD vision chip
A high speed analog VLSI image acquisition and low-level image processing system is presented. The architecture of the chip is based on a dynamically reconfigurable SIMD processor array. The chip features a massively parallel architecture enabling the computation of programmable mask-based image processing in each pixel. Each pixel include a photodiode, an amplifier, two storage capacitors, and...
متن کاملFlexible 3-D shape measurement using projector defocusing.
We present a 3-D shape-measurement technique using a defocused projector. The ideal sinusoidal fringe patterns are generated by defocusing binary structured patterns, and the phase shift is realized by shifting the binary patterns spatially. Because this technique does not require calibration of the gamma of the projector, it is easy to implement and thus is promising for developing flexible 3-...
