Research on Joint Surveying Method Based on BeiDou Positioning and LiDAR Technology
With the development of surveying technology in China,the application of joint surveying technologies based on BeiDou po-sitioning and LiDAR in surveying and mapping projects has become commonplace.The different data processing methods of joint sur-veying methods result in large differences in measurement accuracy.In this paper,by using the factor graph model,a maximum poste-riori estimation factor graph algorithm is established,and the accuracy of the algorithm is analyzed by simulation experiments.Then,by combining with convolutional neural network technology,a surveying system fault detection method is proposed,and the detection efficiency and accuracy of the detection system are analyzed by simulation experiments.
