Abstract

The present invention relates to a tension monitoring system comprising: —at least one camera for acquiring at least one image of at least one pattern located on an object of interest, wherein the pattern comprises a plurality of points and where each point is arranged on the object in such as way as to follow the movement of the object; —a computational device; wherein the computational device is arranged to analyze the acquired image for detecting the position of each pattern point using an image analysis algorithm arranged to determine the geometrical center of a point using a contrast detection method, determining the distance between at least two pattern portions, and calculating the tension induced in the object using a reference value of distance between the two pattern portions when the object is mechanically relaxed.
