为了提高无人机拍摄速率的控制精度,提出基于5G技术的无人机拍摄速率自动校准方法。识别无人机拍摄下的视觉信息,采用视频帧差补偿控制方法进行无人机拍摄的图像像素特征分集和误差补偿设计,提取无人机拍摄图像的灰度像素特征分量,通过关联规则特征参数融合的方法,分析无人机拍摄图像的帧跟踪识别模型,控制无人机拍摄的图像信息传输;根据5G通信的信道差异性特征量进行负载均衡调度,建立无人机拍摄的速率参数估计模型;采用最大似然估计和无人机航拍运动视频跟踪补偿控制的方法,实现无人机拍摄速率自动校准。仿真结果表明,采用该方法进行无人机拍摄速率自动校准的精度较高,提高了无人机拍摄的自动校准水平。
In order to improve the control accuracy of UAV shooting rate,an automatic calibration method of UAV shooting rate based on 5G technology is proposed.The visual information captured by UAV is identified.The pixel feature diversity and error compensation of UAV captured image are designed by using video frame difference compensation control method.The gray pixel feature components of UAV captured image are extracted.The frame tracking recognition model of UAV captured image is constructed by fusing the feature parameters of association rules,so as to control the transmission of image information captured by UAV According to the channel difference characteristics of 5G communication,load balancing scheduling is carried out to establish the rate parameter estimation model of UAV shooting;the maximum likelihood estimation and tracking compensation control method of UAV aerial photography motion video are adopted to realize the automatic calibration of UAV shooting rate.The simulation results show that the accuracy of automatic calibration of UAV shooting rate is high,and the automatic calibration level of UAV shooting is improved.
