摘要: 根据立体测绘相机的数据传输要求,需要将多个图像数据源产生的异步图像数据传输和存储到计算机上,研究和实现了一种实用的完整解决方案。采用FPGA对多个图像数据进行组合,在FPGA内部进行一级缓存,将异步的图像数据源,变换成同步数据,经过独立的FIFO芯片对图像数据进行缓存,方便总线繁忙时对图像进行缓存;然后通过专用的PCI接口芯片,将图像数据传输到PCI总线上;使用DriverWorks进行驱动程序的设计,将数据存入内存中,通过应用程序显示及存储于硬盘中。Abstract: According to request of data transfer in three-dimensional mapping camera, a new solution that will be more useful is investigated and developed. The image data in Multi-channe are combined with FPGA, the data is first cashed in FPGA in order to transfer the Asynchronous data into synchronous data. Then it will again be cached in FIFO. After these processes the data will be transferred to computer bus with PCI9054. With the design of driver and application, the image data can be showed and stored.
