摘要

摘要:设计了一种新的图像注入系统来实现PC机仿真图像到红外处理系统的直接传输。首先,该系统利用USB2.0接收PC机对外场实测数据仿真得到的BMP格式文件,用FPGA控制由两个SDRAM组成的缓冲模块进行图像缓存,然后通过Camera Link接口传送出去。系统数据缓存采用乒乓操作,避免了数据处理时无法持续接收而丢失有效数据的现象。测试时用图像采集卡进行图像采集并显示。结果表明,该系统具有速度快、实时性好、稳定性高等特点,可替代光电跟瞄设备进行仿真训练及设备的动态检验。

Abstract:A new image injection system was presented to realize the direct transmission of PC simulated images. Firstly, the system received a BMP file obtained by simulation for the measured data of the external field using PC though USB2.0. Then, a FPGA was used to control the buffer module consisting of two SDRAMs for the image cache, and the image was sent to the image acquisition card by Camera Link. Finally, the image was acquired by the image acquisition card and displayed on a monitor. The ping-pong operation was adopted for data cache to avoid the condition that the data couldn't be received continuously and valid data may be lost. Experiments show that the image injection system has advantages in well real time, vividly and high-speed features, and provides reliable data for optical equipment scanning and manipulator training.
