Three-Dimensional Shape and Color Texture Acquisition Technique with a Single Monochrome Camera

Color image acquisition using a monochrome camera and standard fluorescence filter cubes.

Single-camera, three-dimensional particle tracking velocimetry.

This paper introduces single-camera, three-dimensional particle tracking velocimetry (SC3D-PTV), an image-based, single-camera technique for measuring 3-component, volumetric velocity fields in environments with limited optical access, in particular, optically accessible internal combustion engines. The optical components used for SC3D-PTV are similar to those used for two-camera stereoscopic-µ...

Colorization for Monochrome Image with Texture

Colorization is a computerized process of adding color to a monochrome image. The authors have developed colorization algorithms which propagate colors from seeded color pixels. Since those algorithms are constructed based on a region growing approach, failure colorization occurs at the place where a luminance changes intensely such as edge and texture. Although we developed, in the previous wo...

An Improved Flexible Camera Calibration Technique for Rock Three Dimensional Shape Measurement System

With these advantages such as no phase shift error, measured fast, portable, high accuracy, the three-dimensional measurement system which is based on the heterodyne principle and digital grating phase-shift technology has been widely used in rock three-dimensional shape measurement. The precision of camera calibration determines the measurement accuracy of the system. In this paper, the Zhang ...

Multispectral integral imaging acquisition and processing using a monochrome camera and a liquid crystal tunable filter.

This paper presents an acquisition system and a procedure to capture 3D scenes in different spectral bands. The acquisition system is formed by a monochrome camera, and a Liquid Crystal Tunable Filter (LCTF) that allows to acquire images at different spectral bands in the [480, 680]nm wavelength interval. The Synthetic Aperture Integral Imaging acquisition technique is used to obtain the elemen...
