【Abstract】： In order to improve the accuracy of the solution of the encryption point coordinates in photogrammetry， a set of procedures for analyzing the nonlinear correction number of network level difference in aerial triangulation of the air triangular measurement area of the air triangular method is written. Using the mathematical model of the nonlinear correction coefficient calculation and nonlinear correction number calculation of the air belt method in aerial triangulation in photogrammetry， the corresponding program is compiled， and the nonlinear correction coefficient and nonlinear correction number of the encryption points are calculated respectively， so as to calculate the ground coordinate data of each encryption point. In view of the research content， considering the need for programming to refine and modify the flat difference model， the program designed the overall framework， on the basis of this algorithm， the program was prepared， the programming was debugged and optimized， and finally the programming was used to calculate the example. Through the analysis of the calculation results， the programme can complete the calculation requirements of the air triangulation air belt method area network balance.
