| Abstract: | Aiming at the problem of real-time image data acquisition in vehicle-mounted UAV(Unmanned Aerial Vehicle) remote sensing system, the image acquisition module was designed and implemented based on embedded platform. The hardware system took ARM(Advanced RISC Machines)microprocessor as control core based on embedded Linux. The overall design architecture and realization of hardware were introduced in detail. The video dynamic display based on V4L2 (Video for Linux 2)and the realization of image acquisition were presented after the completion of camera driver transplantation. Monitoring terminal of image dataacquisition was designed using Qt/Embedded tools and based on LCD ( Liquid Crystal Display) and achieved the function of shooting control and parameter setting.The results of both software and hardware debugging and experiments indicate that the system can accurately control the imaging device and can also storage the image data into memory devices,realized friendly human-computer interaction and achieved the desired effect. |
