| Abstract: | A high-speed embedded image processing system based on digital signal processor (DSP) was developed. The system captured and processed black and white images in high speed; and the max speed reaches 5 frames (one frame has 1024*1500 pixels) per second. The hardware of the system is mainly composed of three parts: a linear CCD sensor, a piece of DSP (TMS320DM642) and the corresponding processing circuit. The hardware design and drive-management of the image processing system are illustrated and the operating principles of CCD sensor and TMS320DM642 are introduced. The algorithm structure and flow chart are also given. |
