A HOIST-POSITIONING METHOD AND INTELLIGENT VISION HOISTING SYSTEM

摘要

A hoist-positioning method and intelligent vision hoisting system in which the video cameras (C1, C2) are mounted on each side of the crane boom respectively, the cooperation marks (P1, P2) are attached to the hook and the object to be hoisted respectively. The hoist-positioning method includes: firstly catching the cooperation mark attached to the sling of the object to be hoisted by the camera (C) mounted on the top of the crane tower, determining the orientation of the object to be hoisted, and controlling the rotation of the boom so as to cause the cooperation mark of the sling into visual field of the two cameras (C1, C2), using the two cameras mounted on the boom to form image of the hook and object simultaneously, and obtaining three-dimensional spatial coordinates of the hook and object; and then according to the three-dimensional spatial coordinates of the hook and object, calculating the parameter and sending it into the controller, after positioning the hook of the tower crane, automatically hoisting the object. The invention has a high-digitalized system and can meet the need of the high reliability and intellectualized by using the video camera measurement technology in the hoisting controlling, it thus lowers the labor strength of the operator greatly and improves the working efficiency.
