Abstract For the incomplete surveying data caused by various factors, traditional adjustment can not be achieved. It is harmful to the accuracy of the surveying, even leads to abandoned observation data. Through EM algorithm, we can take the potential information which is helpful to improve the accuracy of data processing effectively. EM processing algorithm for incomplete surveying data is proved. The results show that the surveying accuracy is improved by using the EM algorithm to process the incomplete data. The results are extremely similar to the adjustment results with complete data and significantly better than the results without adjustment.
Key words ：
