Abstract: A smart line scan camera based on high-speed CMOS sensor is designed. The FPGA is used for front-end pretreatment to transform the LVDSs of the sensor, the DSP is for image process and communication, and the EMIFA interface is for keeping communication with the DSP. The whole software architecture is designed based on SYS/BIOS operating system of TI, including DMA controlling of DSP, Ping-Pang cache, image process and communication.Compared with traditional cameras, the smart line scan camera has many advantages of modular structure, lower cost, more powerful functions and more convenient to use and maintain, and has a wide application space.
Key words: high-speed CMOS sensor; DSP; FPGA; smart line scan camera
