An Improved Automotive Multiple Target Tracking System Design

Multiple Target Tracking (MTT) algorithms are widely used in various military and civilian applications but its use in automotive safety has little been investigated. In MTT algorithms, implemented in embedded systems, it is important to use the minimum required resources to allow the entire DAS system to be integrated on the same chip (data acquisition, MTT and alarm restitution). This allows the reduction of the System on Chip (SoC) complexity and cost. This paper presents an efficient Driver Assistance System (DAS) based on MTT application. To do so, we first identified the performance bottlenecks in the application. In this application, a set of optimizations were applied to reduce the MTT algorithm’s complexity. Tuning in conjunction the hardware and the software yielded to optimize the final system and to meet the functional requirements. The result is a complete embedded MTT application running on an embedded system that fits in a contemporary medium sized FPGA device.
