3D Camera

Vialux developed a 3D camera for the acquisition of full-field 3D surface data with speed and resolution comparable to CCD cameras. The sensing principle of the zSnapper is based upon full-field triangulation. Speeding up the projection of sequences of light patterns is achieved by the use of the DMD Discovery digital micromirror device of Texas Instruments. Vialux supports this MEMS device with its own electronics that enables for 3D frame rates of 25Hz for the VGA resolution and 40Hz for the ½VGA resolution, respectively. Each VGA 3D frame represents 300,000 independent measurements of x, y, z coordinates on the object surface. The short recording time enables not only hand-held operation or fast in-line applications but also the recording of living objects. Multiple z-Snapper cameras can be combined for recording 3D scenes, for example in computer vision.
