应用嵌入式技术、无线传输技术和图像处理技术,设计目标搜索飞行器,为防灾救灾提供技术服务。系统包括手持终端和飞行器,采用ARM11架构的S3C6410微处理器,移植Linux操作系统。飞行器携带摄像头采集图像并压缩,通过wifi传输到手持终端,在本地的TFT液晶屏显示;同时手持终端向飞行器发送控制命令,飞行器根据命令控制自身的运动和摄像头的转动。实验结果表明,采集的图像清晰、命令执行及时可靠,能够较好地完成目标探测、搜索等任务。
Application of embedded technology, wireless transmission technology and image processing technology, the design of the target search for aircraft, disaster relief to provide technical services. The system includes hand-held terminals and aircraft, S3C6410 microprocessor with ARM11 architecture, and Linux operating system porting. The aircraft carries the camera to collect the image and compress it, transmit it to the handheld terminal through the wifi, and display it on the local TFT LCD screen; meanwhile, the handheld terminal sends control commands to the aircraft, and the aircraft controls its own motion and camera rotation according to commands. The experimental results show that the acquired image is clear, the command execution is timely and reliable, and the task of target detection and search can be completed well.
