摘要
The present disclosure relates to a method and device for detecting concealed dangerous objects in microwave images. The method includes: obtaining at least two adjacent microwave images of body detection results; obtaining a body-area image from each of the microwave images; obtaining dangerous-object areas from each body-area image, and performing an edge extraction on each of the dangerous-object areas to obtain a first edge image of each of the microwave images; performing a dangerous-object edge detection on each body-area image to obtain a second edge image of each of the microwave images; performing a first edge fitting operation on the first edge image and the second edge image to obtain dangerous-object edges of each of the microwave images; performing a registration operation and a second edge fitting operation on the dangerous-object edges of each of the microwave images to obtain a rough dangerous-object contour; performing a regional-binarization operation on the rough dangerous-object contour to obtain a first dangerous-object area; and filtering the first dangerous-object area to obtain a second dangerous-object area. The present disclosure has high detection accuracy and calculation efficiency.
