A ruled curve-line conversion detection method was put forward to realize rapid dimension detection of plate parts.Firstly,according to the image characteristics of concentric arcs of plate parts and fixed measuring positions,the fast detection algorithm based on the curveline conversion was designed.Secondly,the ruled detection method was designed,including the measurement path,edge detection parameters,curve-line conversion parameters,calculation rules and so on.Practical applications indicate that rapid dimension detection can be realized with the proposed ruled detection algorithm,and also it is applicable for the measurment of other mechanical parts.
