Abstract
A control device using image tracking technology for controlling overhead crane system is disclosed, in which a plurality of image capturers are used to monitor a operating space and a position of the hoisted load, a respective image of two of which are used to establish a 3D coordinate data, so that an image processor calculates parameters including a hoisted load position (P), a swing angle (θ) and a cable length (l) by referring to the images received, and generates a feedback signal to a crane controller. The crane controller issues a drive signal according to the feedback signal to drive the overhead crane system.
