Method of reducing computational demand for image tracking

Abstract

A method of reducing computational demand for image tracking includes first receiving a plurality of images of a load hoisted with hanging wire in a preset transitional space, setting at least one monitoring point each at the load and the hanging wire, respectively, providing a tracking frame at the outer periphery of each monitoring point, allowing each tracking frame to track on its corresponding monitoring point that each monitoring point is kept on a relative location within each corresponding tracking frame, and producing the same displacement as that of the monitoring point, and lastly computing the displacement of each tracking frame thus obtaining the displacement of each monitoring point in correspondence to the tracking frame to calculate various displacement of the hanging wire and the load, respectively. With this image tracking method, the processing quantity of whole image data is effectively decreased and computational demand of equipments is reduced.
