The invention relates to the technical field of arm type engineering machinery, in particular to an anti-collision method and an anti-collision device for high-altitude operation equipment. A first millimeter-wave radar and a second millimeter-wave radar are arranged at the starting point of an arm support and are diagonally arranged relative to the cross section of the arm support; the detection view fields of the first millimeter-wave radar and the second millimeter-wave radar are mutually orthogonal and cover the boom, the anti-collision method comprises the steps that position coordinate data of an obstacle detected by the first millimeter-wave radar and the second millimeter-wave radar are acquired, and the position coordinate data comprise multiple pieces of coordinate data detected at multiple sampling moments; fitting the plurality of coordinate data to obtain a fitting equation of the obstacle under the arm support coordinate system; determining the movement direction of the arm support; determining coordinates of the obstacle on a coordinate axis corresponding to the movement direction according to the fitting equation; and executing an anti-collision strategy according to the coordinate of the coordinate axis. According to the anti-collision method, the risk that the millimeter-wave radar misses detection of obstacles is reduced, and the collision probability of the cantilever crane is reduced.
