Three-dimensional positioning precision control method

The invention relates to the technical field of hoisting positioning, in particular to a three-dimensional positioning precision control method which comprises the following steps: acquiring three-dimensional online data of hoisting equipment; wherein the three-dimensional online data comprises an X-axis real-time position, a Y-axis real-time position and a Z-axis real-time position; based on the three-dimensional online data, a stable value of the hoisting equipment in the hoisting process is determined; judging and generating a signal whether the lifting hook is stable based on the real-time stable value of the lifting hook; wherein the lifting hook stabilization signal comprises a lifting hook stabilization signal and a lifting hook instability signal; when the lifting hook instability signal is obtained, a lifting hook alignment deviation value and a lifting hook alignment reserved value are obtained, analysis and judgment are conducted, and an influence signal is obtained; according to the method, the de
