Finally, a general GCP error is defined to revise error propagation model and this alteration made the model suitable for more general condition.

为将模型推广至更一般的情况，定义了表观控制点误差对误差传播模型进行修正。

Using the improved error backward propagation, the model is trained with stylebook data and validated its effect by other stylebook data.
