A new and innovative approach for 3D vision systems is presented. The systems can be used not only for the acquisition of 3D distance images, but also for the acquisition of the corresponding 2D gray-scale images. Silicon imagers which are based on so-called photonic mixer devices are the key components. Photonic mixer devices (PMD) represent a new kind of active pixel sensors (APS), fabricated in CMOS technology. With a PMD camera an entire 3D-scene can be monitored. Therefore, PMD technology offers high potential for automotive applications with respect to both active and passive safety. Conti Temic is developing an occupant detection system as a first application of a PMD camera. Further applications, such as traffic environment perception, can benefit from the new opportunities of 3D-vision and are already being considered.
