Disclosed is a method for intelligently recognizing articles in a vehicle, comprising an intelligent monitoring unit, an intelligent image collection unit, a power source module, a communication gateway, an Internet of Things, a wireless gateway and a server cluster. An input end of the intelligent image collection unit is connected to one output end of the power source module, and the other output end of the power source module is connected to an input end of the intelligent monitoring unit. The intelligent image collection unit and the intelligent monitoring unit are both in bidirectional signal connection with the server cluster via the wireless gateway, and the intelligent monitoring unit is in bidirectional signal connection with the Internet of Things via the communication gateway. In the method for intelligently recognizing articles in a vehicle, by means of light correlation devices mounted within security inspection devices at two ends on the ground, when a vehicle drives into light correlation for several seconds, it can be detected, by means of the light correlation, whether prohibited articles are present in the vehicle. This method realizes high efficiency, can avoid a jamming phenomenon at a highway junction caused by manual detection, and satisfies the security inspection requirements of working personnel.
