| Abstract: | A UAV infrared line scanner image acquisition system with storage capacity expanded in ping-pong mode based on SD card was proposed and implemented which satisfied the requirements of infrared line scanner on UAV for large-capacity real-time image data storage.The system makes use of FPGA’s advantage in parallel processing to design a ping-pong SD card storage mode based on BUS control, which can not only greatly improve the storage rate, but also expand the storage capacity according to actual demand; It also makes use of DSP’s advantage in logic operation to design, implement the FAT32 file system and transplant the Embedded File System on SD card successfully.The image playback and analysis software was compiled based on graphical language Labview, and the results shows that the image acquisition can be effectively applied in infrared line scanner, meeting the need of the practical application. |
