Theodolite measurement error factors,presents a weighted factor in nonplanar intersection method.First of all,will personally set up different measurement theodolite simulation,then the existence of different surface error control design problem using the weighted factors,introduction of the human factor as a measurement error model parameters implicit in the model,using optimization method for solving the constraint equations,solve for theodolite model parameters,thus theoretically eliminating the error caused by human factors,to improve the measurement accuracy of the model,and finally to establish a spatial object model and simulated,are the coordinates of the optimized trajectory measurement,The simulation result indicated the error is smaller than the junction to meet the error,obtains the data real response flight track,enhances to is measured the goal the pointing accuracy.
