Paper Abstract

Range image acquisition can be made in many different ways. In this paper we use an active triangulation method where a sheet-of-light illuminates the scene. The sensor-level signal processing task addressed here is to extract the light impact position in each sensor row. We use a thresholding algorithm implemented on the smart sensor MAPP2200 to extract the range data from the sensor data. The range images can be output with very high frame rates (up to and above video rate). The programmability of the sensor makes it possible to generate range images with arbitrary range resolution or image size. Reducing the image size or resolution gives us higher range image frequency. We also present an error correction scheme not found in any other smart sensor implementation.
