给出了一种能够高速同步采集多路黑白视频信号，采集的精度为８位，采样率为１４．７６８ＭＨｚ．此系统设计以现场可编程门阵ＦＰＧＡ为核心元件，将系统的采样控制逻辑与压缩存储逻辑集成在一块ＦＰＧＡ芯片上，与采用单片机或通用器件实现相比，具有速度快、可靠性高、结构简单、体积小等优点，而且设计周期短、灵活性大，我们已经将其应用在高速高精度的三维净空测量中． A high-speed simultaneous acquisition of multiple black-and-white video signals is given. The accuracy of the acquisition is 8 bits and the sampling rate is 14.768 MHz. This system is designed with field programmable gate array (FPGA) as the core component. The system’s sampling control logic and compression storage logic are integrated in one FPGA chip. Compared with using single chip microcomputer or general-purpose device, this system has the advantages of fast speed, high reliability, Simple, small size and other advantages, and the design cycle is short, flexible, we have applied it in high-speed high-precision three-dimensional headroom measurement.
