Driver Drowsiness Detector
The logiDROWSINE is a computer vision IP core that detects driver drowsiness and distraction based on facial movements monitored through a camera placed in a vehicle cabin. The IP core monitors movements of driver's eyes, gaze, eyebrows, lips and head, and continuously tracks nine facial behavioral features that indicate the drowsiness: PERCLOS, microsleep, yawn and others. Based on the behavioral features tracked during the driving, the implemented classifiers recognize seven levels of drowsiness that can be used as driver alerts or inputs in other ADAS applications.
The logiDROWSINE is carefully partitioned between hardware and software to assure high performance and optimal utilization of the Xilinx Zynq-7000 AP SoC. The complete driver drowsiness SoC design, which consists of the logiDROWSINE, logiFDT and other IP cores, fits into the smallest Xilinx Zynq SoC and use only a single CPU core. It is prepackaged for the Xilinx Vivado Design Suite and IP deliverables include the software driver, documentation and technical support.
