METHOD FOR EXTRACTING SHAPE FEATURES, METHOD AND DEVICE FOR SECURITY INSPECTION

摘要

Disclosed are a method for extracting shape features, a method and device for security inspection. A three-dimensional structure of an object is acquired by utilizing a CT (S42). Symmetric metric values of multiple depth projection images are acquired (S45). The shape features of the object are extracted (S46). Whether or not the object is an explosive is detected on the basis of the shape features and material features of the object. Accuracy is increased.
