Printing Detecting Algorithm Basing on Maximum Degree of Recognition

Hu Zhang, Feng Guo


In modern packaging, printing industry, due to effects of the properties of the strip itself and the ambient light, strip background color and the color of the printing line, the low contrast boundaries of the strip on both sides and so on, the traditional digital qualitative detection and control to the correction system does not meet the comprehensive requirements. This paper aims to study the detection of a continuous line, discontinuous line and color dividing line on the strip, and because of low contrast between background color and dividing line, we proposed an innovative solution and implementation. This article discusses a new algorithm basing on maximum degree of recognition and optimal light source search algorithm, and we simulated this in MATLAB, finally, we completed the physical testing of the overall system.
