To solve the problems of horizontal directional drilling trajectory deviation correction,an automatic correction algorithm was put forward.After constructing the control system and feasible trajectory monitoring method,necessary input information was got.Rectification model was simplified to point to point model,using the method of curve?straight?curve.Through deeply analyzing the model,a solution was put forward,which solves the geometric information,key point coordinates and arbitrary point coordinates.The algorithm was simulated in software and verified.The results show that the proposed algorithm is practical and can be referred in other systems having the similar requirements.
