Detection method, device and system

Abstract

The embodiment of the invention provides a detection method, device and system. The detection method comprises the following steps: acquiring at least two pieces of first position information before particles pass through a to-be-detected object and at least two pieces of second position information after the particles pass through the to-be-detected object, the to-be-detected object being a metal product; reconstructing a first track before the particle passes through the to-be-detected object based on the at least two pieces of first position information; reconstructing a second track after the particle passes through the to-be-detected object based on the at least two pieces of second position information; processing the first track and the second track to obtain feature information of the to-be-detected object; and determining a detection result of the to-be-detected object according to the feature information and preset feature information of the target type object. According to the detection method provided by the embodiment of the invention, the accuracy of a detection result can be improved.
