Title:
INSPECTION METHOD AND INSPECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/188653
Kind Code:
A1
Abstract:
Disclosed are an inspection device and an inspection method. The method comprises: carrying out X-ray scanning on a container to be inspected so as to obtain a transmission image, then using a convolutional neural network to generate, from the transmission image, a first vector describing the local transmission image, and using a recurrent neural network to generate a word vector, from a text description of cargoes in the container, to serve as a second vector; integrating the first vector and the second vector so as to obtain a third vector expressing the transmission image and the text description; and determining, based on the third vector, the category of the cargoes in the container. According to the embodiments of the present disclosure, the general category of target cargoes can be preliminary determined, thereby facilitating an image determiner in making a further determination.
