无人机地质图像传输设计与实现
|
摘要
为解决区域小范围地质测绘难以有效传输的问题,文中提出一种基于无人机的地质图像传输方法,设计并实现了系统的各个硬件节点和模块软件.以ZigBee无线网络作为数据链路,将无人机采集的图像传输至地面接收系统,通过图像分包、合并和停止等待协议等确保了图像在传输过程中的数据正确性.在复杂地形山区进行了实验测试,测试结果表明:在图像数据小于1 024kbyte的情况下通过分包合包,可实现无人机和地面端计算机间图像文件的正确传输.
With the maturity of UAV technology,especially the cost of the four rotor unmanned aerial vehicle(UAV)is decreasing,and will be a trend in the future.At the same time,ZigBee has the characteristics of low cost,low speed and short transmission distance,it can be used to achieve the transmission of image files between UAV and ground computer system.This paper design the hardware nodes and software program modules,using wireless network as the data link,the UAV send the data to the ground computer,image in the transmission process through subcontracting,merger and stop to wait protocol to ensure the correctness of data transmission.Through experimental test,the correct transmission of image files between UAV and ground end computer can be realized when the image data is less than 1 024 kbyte and get a perfect effect.
