  • 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.
