Abstract: In order to overcome the problem of high detection absolute error rate and complexity of detection time in traditional methods, this paper proposes a method of colour difference detection based on local enhancement. The projection value of the colour area block of the outer packaging is determined. The threshold segmentation method is used to detect the colour difference of the outer packaging of the product. The difference pixels are extracted by local enhancement method to detect the colour difference of the outer packaging. The results show that the average accuracy of the method is 98.6%, the time of colour difference detection is only 6S, and the absolute error rate of colour difference detection is 0.26%. This method can effectively reduce the complexity of detection time, reduce the absolute error rate of detection, and improve the correct identification rate of colour difference of outer packaging.
