Abstract
Provided are a method and a system for controlling operation of a crane, and a crane. The method includes: scanning dynamically, by a 3D imaging device, a plurality of objects within an operating range of the crane to obtain 3D spatial information of each of the plurality of objects, wherein the plurality of objects includes the crane and an obstacle, the 3D spatial information includes 3D spatial coordinates; determining a distance from the obstacle to a preset position of the crane based on the 3D spatial coordinates of the crane and the obstacle; judging whether the distance from the obstacle to the preset position is less than a preset distance corresponding to the preset position; and performing an alarm if the distance from the obstacle to the preset position is less than the preset distance corresponding to the preset position.
