CRANE CONTROL METHOD, SYSTEM AND CRANE BASED ON IMAGE PROCESSING

摘要

A crane control method, a system and a crane based on image processing are disclosed. The control method comprises: in the double lifting mechanism of a crane, obtaining the image respectively that can reflect the winding state of the ropes wound on the drum of the lifting mechanism; decoding the image obtained and binaryating the image respectively so as to generate two data matrix; comparing the two data matrix so as to judge whether the hook crossbeam inclines; and adjusting the rotating speed of the motor so that the hook crossbeam tends to level when the hook crossbeam inclines. Said technical solution can judge whether the hook crossbeam inclines by processing the image, and adjust the motor rotating speed in case of the tilt so that the hook crossbeam tends to level, thus can avoid the problems caused by the tilt of the hook crossbeam.
