中文摘要:
      视觉导航已经成为微型飞行器的主要导航方式之一,为了给视觉导航技术的研究提供验证平台,设计了一种数字图像实时采集传输方案,以IEEE 1394b高速光总线作为传输协议,以FPGA为控制核心生成图像传感器时序控制逻辑、FIFO缓存模块以及1394b协议链路层IP核。图像数据经FIFO缓存后打包成1394b格式的数据包,经过电光转换后通过光纤发送给插有1394b采集卡的计算机,利用Visual C++对接收到的数据进行处理,实现了图像的显示和存储功能。测试结果表明,系统的平均传输速率为123.264 Mb/s,能够满足系统的实时性要求。
英文摘要:
      Vision navigation has become one of the main navigation methods of micro air vehicles. In order to provide a platform for the research of visual navigation technology, a digital image real time acquisition and transmission scheme is designed. The IEEE 1394b bus is used as the transmission protocol. FPGA, as the control core, generates the timing control logic of the image sensor, FIFO buffer module and 1394b protocol link layer IP core. The image data is packaged into the 1394b format after the FIFO buffer, and then transmitted to the computer with a 1394b acquisition board through the optical fiber after signal conversation. The C++ Visual is used to process the received data, and the display and memory functions of the images are realized. Test results show that the average transmission rate of the system is 123.264 Mb/s, which could meet real time requirements.
