Surface Profile Measurement of Specular Objects by Grating Projection Method. (2nd Report). Measurement of Ellipsoidal Mirror.

A one-shot-projection method for measurement of specular surfaces.

In this paper, a method is proposed to measure the shapes of specular surfaces with one-shot-projection of structured laser patterns. By intercepting the reflection of the reflected laser pattern twice with two diffusive planes, the closed form solution is achieved for each reflected ray. The points on the specular surface are reconstructed by computing the intersections of the incident rays an...

3D Profile Measurement by Color Pattern Projection and System Calibration

In this paper, we present a new color structured lighting for 3D profile measurement by projecting a pattern of color stripes. The advantage of using color pattern is that it simplifies the difficult matching problem of using a multiple-line stripe pattern. The problem of finding the correct color stripe correspondence between light source and images is solved by accurately calibrating the syst...

A New Profile Measurement Method for Thin Film Surface

In order to measure the surface profile of the thin films in wide area with high accuracy, the research on the new measurement method was conducted and many patents on measurement method and system were researched. Based on the physical properties of soft thin film, the method of using white interferometer and ball cantilevers for measuring the surface profile of thin film is proposed. Then, th...
