Document Type and Number:
WIPO Patent Application WO/2020/134847
Kind Code:
A1
Abstract:
Disclosed are a foreign object detection method, a security check apparatus, and a device having a storage function. The method comprises: acquiring a millimeter wave signal reflected by a subject being checked; inputting the reflected millimeter wave signal to a three-dimensional foreign object identification network, and acquiring an identification result of the three-dimensional foreign object identification network, thus detecting whether the subject being checked is carrying a foreign object, where the three-dimensional foreign object identification network is a pretrained three-dimensional convolutional neural network. By such means, the present application implements quick and accurate foreign object detection.
