Based On Dsp-finger Visual Feature Recognition And Positioning System Software Design

This paper designs a set of DSP/BIOS real-time software system based the DM642 Digital signal processor platform to achieve the identification and location of the finger. The real-time software contains two main parts, which are scheduling programmer and bottom-driver. The scheduling programmer of the tasks is designed based on the task management module of DSP/BIOS. And the bottom-driver is designed with the CSL based on the input-output module of DSP/BIOS. I achieve the optimization of the fingers identification and location algorithm which based on the fingers color with some methods. In the laboratory environment the system was tested with the real-time analysis tools of DSP/BIOS. Test results show that the system stability and meet the real-time requirements.
