CSEM Demos Miniature Vision Sensor System for Real Time Analysis and Response at SAE World Congress.Low-Cost ViSe Impervious to Rapidly Changing Light Conditions, Enabling Broad Application Base DETROIT -- The Swiss Center for Electronics and Microtechnology Microtechnology is technology with features near one micrometre (one millionth of a metre, or 10-6 metre, or 1μm). In the 1960s, scientists learned that by arraying large numbers of microscopic transistors on a single chip, microelectronic circuits could be (CSEM CSEM Centre Sismologique Euro-Méditerranéen (France) CSEM Centre Suisse d'Electronique et de Microtechnique (Switzerland) CSEM Case Studies in Environmental Medicine (ATSDR) ), a leading electronics R&D center, today announced it will demonstrate a miniature vision sensor system for multiple automotive applications at the SAE World Congress (Booth #848). The company will offer a test drive in Detroit to qualified customers. The cost-effective system, called ViSe, enables monitoring and recognition of video data in real time, in changing light conditions. It allows original equipment manufacturers (OEMs) to develop application-specific image recognition and response systems for lane departure warning systems A lane departure warning system (LDW) is a mechanism designed to warn a driver when the vehicle begins to move out of its lane (unless a turn signal is on in that direction) on freeways and arterial roads. (LDWS LDWS Lane Departure Warning System ), rear view monitoring, object detection, parking assistance and seat occupancy. The ViSe LDWS application has been tested on Michigan roads in adverse conditions with outstanding results for a wide range of roads. The system can be customized to fit any existing car security requirements. Faster Processing for Real-Time Analysis The conventional approach to processing image information involves acquiring an image with a CCD CCD in full charge-coupled device Semiconductor device in which the individual semiconductor components are connected so that the electrical charge at the output of one device provides the input to the next device. or CMOS camera A digital still or video camera that uses a CMOS-based image sensor chip rather than a CCD to record the picture. The CMOS image sensors enable the integration of all required camera circuits onto the same chip, making them well suited for tiny cameras such as in PDAs and cellphones. , converting the intensity distribution to a digital representation, and processing it by means of a digital processing Digital processing is the process of altering digital data in any form. The most common situations where digital processing is involved are computer graphics and digital audio processing. device. This approach poses considerable problems in automotive markets where vision tasks must be executed in real-time and at a low system cost, in environments with uncontrolled levels of lighting. The ViSe camera is composed of a vision sensor and a digital signal processing See DSP. Digital Signal Processing - (DSP) Computer manipulation of analog signals (commonly sound or image) which have been converted to digital form (sampled). chip (DSP (1) (Digital Signal Processor) A special-purpose CPU used for digital signal processing applications (see definition #2 below). It provides ultra-fast instruction sequences, such as shift and add, and multiply and add, which are commonly used in math-intensive ) that can run identification algorithms. The system speeds throughput of visual data by enabling the vision sensor chip itself to extract key contrast features needed for interpretation -- prior to sending it for to the DSP for recognition processing. "The automotive market requires fast, reliable and affordable vision technology that can be applied for multiple driver safety uses," said Dr. Christian Enz, vice president of the Microelectronics Group at CSEM. "With its real time operation, its ability to deal with changing light conditions, and its cost effective components, this technology can easily be deployed beyond just the luxury car market to make all vehicles safer." Insensitivity to light conditions Whereas other vision sensing systems can be susceptible to rapidly changing light conditions - for example, when a car emerges from a tunnel into glaring light - the ViSe contrast extraction approach eliminates sensitivity to this light environment change, ensuring greater safety and security. Availability and pricing A ViSe evaluation kit is available now and the technology can be licensed for transfer. The system is aimed at OEMs who will adapt it for specific applications. CSEM will add specific algorithms for dedicated applications upon request. Technology licensing fees depend on application-specific criteria.
