Hardware defect classification recognition method based on depth convolution neural network

Abstract

The invention discloses a hardware defect classification recognition method based on a depth convolution neural network, and the method comprises the steps: building a network: constructing the depth convolution neural network; training the network: classifying collected images into two classes: a training set and a test set, wherein the training set comprises 70% of the collected images, and the test set comprises 30% of the collected images; recognizing defects: inputting a hardware image in the test set into the trained sample, inspecting the output result, contrasting a recognition result and the label of the image, and carrying out the statistics of the correct recognition rate and wrong recognition rate. The method employs the depth convolution neural network, saves a complex image processing algorithm, achieves the extraction of more abstract features of defects through the adding of a network depth, is stronger in distinguishability between different defect classes, and is higher in recognition rate.

Problems solved by technology

It can be seen that the above-mentioned traditional defect recognition algorithm is very dependent on the accuracy of defect region segmentation, and needs to manually select and extract defect features

However, for the image of hardware products in this paper, due to the serious noise interference, the accurate segmentation of defects requires a complex image processing process, and the amount of calculation is very large
