摘要
利用高帧频 CCD图象传感和高速 DSP(TMS3 2 0 C40 ) ,设计出先进的动态图象高速采集和 RS- 4 2 2 A数据传输系统 ,将光学图象转化为便于计算机处理的数字化图象。以高速 DSP及快速存储器为核心设计并实现高速图象的数字缓冲接口系统 ,与 PC主机构成双机系统 ,并采用 DMA数据通信方式 ,以提高数据的传输速度 ,使采集系统主机能正确接收和处理图象数字信号。
High frame rate CCD (Charge Coupled Devices) and high speed DSP(TMS320C40) used as the sensor of image, a advanced system of high speed image sampling and high speed data transfer with RS-422A have been designed. With this testing system, the optical image can be converted into digital image for the convenience of computer processing. With the high speed DSP (TMS320C40) and memories as the core of the testing system, the interface of high rate data buffer between computer and the CCD camera has been implemented. Meanwhile the double CPU system of the communication with DMA technology is made of the DSP chip and host computer.
