| Abstract: | With the wider application of biometric identification technology, the demand for safety and reliability of access control system becomes higher and higher in market. The realization method of an access control system based on real-time embedded operating system DSP/BIOS and face recognition is put forward, its overall design as well as TMS320DM642-based hardware and software design is introduced. Using camera to acquire face images, DSP to complete the extraction and recognition of facial features, serial port to communicate with outside, the system achieves the target of low cost, high speed and reliability. |
