Topography and color study of an object using fringe projection and colorimetry techniques

Abstract

Besides the topography of an object, color and texture are important parameters to study in some fields. In food industries, variations in color and volume of a piece of fruit are important in order to determine its condition. Using the fringe projection technique, the topography of an object is evaluated through time; hence the change of volume. Using colorimetric techniques, optical devices can be profiled and calibrated. The change of topography and color are measured every 3 days during two months in order to make comparisons with the previous measurements of volume and color. Thus, the condition of food or a piece of fruit can be evaluated as it evolves through time.
