Method and device for automatically recognizing objects based on artificial intelligence deep learning

Abstract

The invention discloses a method and device for automatically identifying objects based on artificial intelligence deep learning. The method mainly includes: collecting X-ray images of items to be identified by X-ray machines arranged in different directions in the item identification area; The obtained X-ray images from all directions are simultaneously input into the preset deep learning model to extract the multi-dimensional data corresponding to the items to be identified in the X-ray image; the multi-dimensional data are fused to generate data features corresponding to the multi-dimensional data; by Classification features and location features are respectively extracted from the data features; the confidence value of the classification feature is calculated, and the combination of the classification feature and the corresponding location feature with a confidence value greater than the preset minimum value is output as the recognition result. It uses cross-imaging and preset deep learning models to synthesize multi-dimensional collected images into a composite image, which greatly improves the recognition rate of contraband, avoids missed detection, and realizes fully automated security inspections.

AI Technical Summary

Problems solved by technology

However, in this technical solution, although the deep learning model is used to realize the automatic detection and identification of contraband, but in this solution, the X-ray machine is only set at one angle, but in view of the different angles of the items placed, There is no difference in the images obtained at the same angle for different items. For example, for a knife, if it is placed on a plane, the image taken from above will look like a knife, and when the same knife is placed vertically, The image captured above is a straight line, which is basically the same as a stick, so using the technical solution disclosed in the above patent still has the risk of detection and recognition errors, and the accuracy rate is not high
