This method locates the angle difference of the tool by adding an angle detector to the capture tool

compares the difference between the last tool position and the target position through a sub-linear algorithm

gives position correction information

and enters the position correction through Unity (Microsoft HoloLens). The information and guidance information are superimposed on the frontal three-dimensional image collected by the 3D camera

and displayed by the mixed reality display terminal

which can significantly improve the success rate of target recognition.
