Abstract
A system for measurement of three-dimensional motion of an object is provided. The system includes a light projection means adapted for projecting, for distinct time intervals, light of at least two different colors with a cross-sectional pattern of fringe lines onto a surface of the object and also includes image acquisition means for capturing an image of the object during an exposure time, wherein the distinct time intervals are within the duration of the exposure time. The system further includes image processing means adapted for processing the image to obtain a different depth map for each color based on a projected pattern of fringe lines on the object as viewed from the position of the image acquisition means, to determine corresponding points on the depth maps of each color, and to determine a three-dimensional motion characteristic of the object based on the positions of corresponding points on the depth maps.
