Abstract
It is difficult to measure three dimension profile and positions of a moving object by using only one group of grating projection fringes because the absolute position of the object couldn't be determined. We introduce two reference-tracking fringes into the conventional fringe pattern projection system, from which we determine the moving direction and absolute coordinate of the moving object. The 3D profile of the object is determined from the distorted fringes, and the absolute coordinate of that is determined from the angle of the reference-tracking fringes. This method enables us to track a moving object, and measure it with a large measurement range.
