Speed Camera Control

Standard Components Used in this Example

To make traffic management safer and to achieve a smoother, quieter and calmer traffic flow, computer-controlled multi camera systems are used for speed and red light offenses. Day and night, the cameras automatically photograph vehicles driving through red lights and exceeding a pre-set threshold speed, often monitoring several lanes in parallel. At the start and the end of a road section (with lengths between 500 m and 100 km), a digital image is taken. The intelligent system automatically compares these images by using the details of the vehicle, achieving an extremely high matching percentage. The speed of the vehicle is calculated by using time measurement. Offense images captured can be downloaded to a computer or back office. Captured images are securely encrypted to ensure that they are tamperproof.

One application is based on a Computer-On-Module concept with a PowerPC MPC 8245 on a standard COM and all interfaces routed to a custom carrier board. The overall solution is very compact in order to fit inside the small camera housing and it is qualified for -40 to +85°C operation temperature according to the climatic conditions of an outside installation. The additional functionality is implemented by means of IP cores in the FPGA which is located on the COM. This functionality comprises standard IP cores like additional COMs, IDE, interrupt controller, or a separate watchdog for system reset. It also comprises very application-specific IP cores like the camera interface and a highly-optimized compression algorithm which does the complete frame grabbing and encryption in the FPGA without loading the processor.

Another application is based on a 19" 3U CompactPCI system with a COTS single-board computer based on Intel Core technology. A CompactPCI side-card extends the state-of-the-art PC interfaces of the CPU board by two more Gigabit Ethernet interfaces on rugged Lemosa connectors and provides a slot for a 100 GB+ SATA hard disk for camera data storage. A second SATA hard disk can be connected via rear I/O from the CPU card. The system provides up to 15 slots that can be filled with other functions as required by the application, e.g., GPS and other wireless connections.
