FLUOROSCOPIC INSPECTION METHOD, DEVICE AND STORAGE MEDIUM FOR AUTOMATIC CLASSIFICATION AND RECOGNITION OF CARGOES

摘要

The present disclosure relates to a fluoroscopic inspection system for automatic classification and recognition of cargoes. The system includes: an image data acquiring unit, configured to perform scanning and imaging for a container by using an X-ray scanning device to acquire a scanned image; an image segmenting unit, configured to segment the scanned image into small regions each having similar gray scales and texture features; a feature extracting unit, configured to extract features of the small regions; a training unit, configured to generate a classifier according to annotated images; and a classification and recognition unit, configured to recognize the small regions by using the classifier according to the extracted features, to obtain a probability of each small region pertaining to a certain category of cargoes, and merge small regions to obtain large regions each representing a category.

1. A fluoroscopic inspection method for automatic classification and recognition of cargoes, comprising:
performing scanning and imaging for a container by using an X-ray scanning device to acquire a scanned image; segmenting the scanned image into small regions each having similar gray scales and texture features; extracting features of the small regions; generating a classifier according to annotated images, and/or storing or updating an existing classifier; and recognizing the small regions by using the classifier according to the extracted features, to obtain a probability of each small region pertaining to a certain category of cargoes, and merging small regions to obtain large regions each representing a category.
