| description | The invention provides a method for accurately measuring the distance between a crane jib and electrified equipment. The method comprises the following steps: periodically obtaining the longitude and latitude of the head end of the crane jib during the hoisting operation of a crane; converting the longitude and latitude of the head end of the crane jib at each period moment into corresponding three-dimensional position coordinate values, and correcting the three-dimensional position coordinate values of the head end of the crane jib at each period moment based on a preset three-dimensional position error correction model; and obtaining the three-dimensional position coordinate value of the electrified equipment, and respectively calculating the three-dimensional position coordinate correction value of the head end of the crane suspension arm at each period moment to obtain the distance between the head end of the crane suspension arm and the electrified equipment at each period moment. The invention further p |
