The invention provides a method for obtaining the position of a crane jib. The method comprises the steps that an XYZ three-dimensional rectangular coordinate system is constructed in a simulation mode; periodically receiving first and second data measured by the first and second distance measuring sensors; according to the first data, obtaining a first distance of the first distance measuring sensor in the axial direction of the crane jib in each period moment and taking the first distance as the operation length of the crane jib; according to the second data, the first height of the second distance measuring sensor in the vertical direction in each period moment is obtained, and the second height of the first distance measuring sensor in the vertical direction in each period moment is obtained by combining the preset distance and the first distance and serves as the operation height of the crane jib; and on the basis of the XYZ three-dimensional rectangular coordinate system, X-axis and Y-axis coordinate values of vertical projection of the second distance measuring sensor are positioned, and the included angle between the vertical projection point and the X positive axis at each period moment is obtained and serves as the operation rotation angle of the crane jib. According to the invention, the length, height and angle of the crane jib during the hoisting construction of the crane can be accurately judged.
