摘要：
Based on the needs for the development of the miniaturization and mobility for gaze tracking technology, this paper presents a design proposal about embedded pupil location system. By using processor DM3730 as the core of the hardware platform, we have realized dual-core communication between the ARM and the DSP. This design can make full use of the hardware resources and improve the execution speed of the algorithm. The software graphical interfaces use the methods of interprocess communication. Through calling the executable file generated by ellipse fitting algorithm based on the least-square principle, the accurate location of the pupil can be realized. Experiments show that the system achieved a rate of 25 frames per second for the human eye pupil location, which is a good result and lays the foundation for the implementation of the embedded gaze tracking system.
