Abstract
This paper describes a new method for fast 3D measurement based on active triangulation. In this approach the scene is inspected by a typical CCD camera and illuminated with a single structured light consisting of a multiple circular formed pattern. Data acquisition with video frame rate is guaranteed by the use of special picture preprocessing hardware and the reading of off-line computable table entries that represent 3D information. Based on a high-accuracy camera model and subpixel resolution this new method performs 3D measurement with an average accuracy of 2*10-4 relative to depth of field. Therefore this method is suitable for real-time industrial applications.
