摘　　要：针对露天矿地面能见度监测成本高的难题,提出了一种基于云边协同的能见度监测方法。以卡车定位信息与移动车载摄像头获取的图像为原始数据,根据暗通道先验理论计算图像的透射率信息,进而计算出卡车所处位置的能见度信息,并上传至服务器端;在此基础上,假设露天矿地面能见度变化在空间上遵循平稳随机过程特性,以所有卡车计算的能见度信息对整个露天矿进行克里金估值,最终获得露天矿地面能见度的时空分布情况。在新疆疆纳露天矿开展的试验发现:准确率方面,该方法的平均绝对误差百分比为9.2%,具有较高的精度;实时性方面,监测结果能够动态跟踪露天矿地面能见度实际变化情况;监测方法具备对露天矿地面能见度进行时空动态监测的能力。A cloud edge collaborative visibility monitoring method is proposed to address the high cost of surface visibility monitoring in open-pit mines.Using the positioning information of the truck and the images obtained from the mobile onboard camera as raw data,the transmittance information of the images is calculated based on the dark channel prior theory,and the visibility information of the truck's location is then calculated and uploaded to the server.On this basis,assuming that the visibility changes on the surface of the open-pit mine follow the characteristics of a stationary stochastic process in space,the entire open-pit mine is estimated using kriging based on the visibility information calculated by all trucks,and the spatiotemporal distribution of the open-pit mine surface visibility is finally obtained.The experiment conducted in Xinjiang jiangna Open-pit Mine finds that in terms of accuracy,the average absolute error percentage of this method is 9.2%,indicating high precision;in terms of real-time performance,the monitoring results can dynamically track the actual changes in surface visibility of open-pit mines.The monitoring method has the ability to dynamically monitor the spatiotemporal visibility of open-pit mines.
