For a long time, this goal is realized with the assistance of reasonably distributing GCPs (ground control points).
长期以来，这一目标是借助合理分布的地面控制点来间接实现的。
With IMU/DGPS system, it can process bundle adjustment successfully with less GCPs or even without GCPs with a GPS base station located in a certain scope.
由于配备IMU/DGPS系统，在一定的基站范围内可以在无控制或少量控制点的情况下进行空三平差，极大地减轻了摄影测量外业控制工作量，缩短了生产周期，提高了作业效率。
Collinearity Equation Model. Besides, the neural network can eliminate the influence of GCPs with gross error, and hence can better improve the efficiency.
网络模型能够自动抑制含较大误差控制点对模型纠正精度的影响，在实际应用中可以提高几何纠正效率。
To the problems of dynamic programming stereo matching algorithm modified by ground control points (GCPs), a pyramid two-level dynamic programming stereo matching algorithm is proposed.
针对控制点修正的动态规划立体匹配算法存在控制点求取时间长、实时性差的问题，提出一种金字塔双层动态规划立体匹配算法。
