Automatic calibration method for hole position parameters of crane boom pin, computing equipment and crane

The invention provides an automatic calibration method for hole position parameters of a crane boom pin, computing equipment and a crane. The automatic calibration method for the hole position parameters of the crane boom pin comprises the steps of when the boom pin is inserted into a hole position of a telescopic boom of the crane, controlling the telescopic boom to stretch out or retract through an oil cylinder; and according to the operation state of the oil cylinder, determining the maximum position value and the minimum position value of the hole position, wherein the operation state comprises at least one of the change conditions of the length value of the oil cylinder or the pressure value of the oil cylinder and the movement stopping time of the oil cylinder. The automatic calibration method for the hole position parameters of the crane boom pin, the computing equipment and the crane have the beneficial effect that the hole position parameters of the telescopic boom of the crane can be accurately and
