Problems solved by technology

[0005] However, due to differences in viewing angles, operating experience, etc., the operator may choose the wrong vibration signal threshold, resulting in wrong inspection results
For example, if a large car is mistakenly selected as a small car, it is easy to cause someone to be misjudged as no one, resulting in false positives; and if a small car is mistakenly selected as a large car, it is easy to cause no one to be misjudged as someone, resulting in false positives

Embodiment 1

[0048] figure 1It is a schematic structural diagram of the device for inspecting people hidden in vehicles according to Embodiment 1 of the present invention. Such as figure 1 As shown, the equipment can mainly include:

[0049] A microseismic inspection device 11 for obtaining vibration signals of the inspected vehicle when the inspected vehicle is parked in the inspection area;

[0050] Under-vehicle image acquisition device 13, which is used to acquire the under-vehicle image of the inspected vehicle; and

[0051] A vibration signal threshold determination device 15, which determines the vibration signal threshold of the inspected vehicle based on the vehicle bottom image acquired by the vehicle bottom image acquisition device 13, and transmits the determined vibration signal threshold data to the microseismic An inspection device 11, so that the microseismic inspection device 11 can judge whether there is a person hiding in the inspected vehicle by comparing the vibra...

Embodiment 2

[0055] figure 2 It is a schematic structural diagram of the device for inspecting people hidden in vehicles according to Embodiment 2 of the present invention. figure 2 Winning mark and figure 1 The same components have the same functions, and detailed descriptions of these components are omitted for brevity.

[0056] Such as figure 2 shown, with figure 1 The main difference between the shown equipment for checking people hiding in vehicles is that the under-vehicle image acquisition device 13 of the equipment may include:

[0057] Under-vehicle scanner 21, for obtaining described under-vehicle image; Preferably, under-vehicle scanner 21 can be the line array CCD type camera that two front and rear intervals are installed, and two under-vehicle scanners work with the same timing, It is used to obtain two underbody images of the inspected vehicle that are simultaneously collected at different positions at the front and rear.

[0058] Such as image 3 As shown, it is ...

Embodiment 3

[0067] Figure 4 and Figure 5 It is a flow chart of the method for checking the hidden people in the vehicle according to the third embodiment of the present invention, as Figure 4 and Figure 5 As shown, the method can mainly include:

[0068] Step 101, obtaining the bottom image of the vehicle under inspection;

[0069] Step 102, based on the under-vehicle image, determine the vibration signal threshold of the inspected vehicle;

[0070] Step 103. Obtain the vibration signal of the inspected vehicle when the inspected vehicle is parked in the inspection area;

[0071] Step 104 , comparing the vibration signal with the corresponding determined vibration signal threshold, and judging whether there is a person hiding in the vehicle under inspection.

[0072] In a possible implementation manner, step 101 may specifically include: acquiring two under-vehicle images of the inspected vehicle that are simultaneously acquired at different front and rear positions.

[0073] In...

Abstract

The invention relates to equipment and a method for inspecting personnel hidden in a vehicle, wherein the equipment comprises a micro-vibration inspection device which is used for acquiring a vibration signal of an inspected vehicle on condition that the inspected vehicle is parked in an inspection area; a vehicle bottom image acquiring device which is used for acquiring the vehicle bottom image of the inspected vehicle; and a vibration signal threshold determining device which determines a vibration signal threshold of the inspected vehicle based on the vehicle bottom image that is acquired by the vehicle bottom image acquiring device and transmits data of the determined vibration signal threshold to the micro-vibration inspection device so that the micro-vibration inspection device can determine whether personnel are hidden in the vehicle through comparing the vibration signal with the determined vibration signal threshold. The equipment and the method sufficiently utilize information such as the vehicle bottom image for performing vibration signal threshold identification on the inspected vehicle and furthermore does not require artificial intervention. The equipment and the method have advantages of more accurate and quicker identification result in determining whether personnel hide in the vehicle, effective inspection speed improvement and more convenient use.

Description

technical field [0001] The invention relates to the field of security inspection, in particular to an inspection device and method for inspecting whether a person is hidden in a vehicle. Background technique [0002] It is one of the contents of safety inspection to check whether there are people hiding in the vehicle, and microseismic inspection technology is generally used at present. The principle of the microseismic inspection technology is that if someone is hidden in the vehicle, the vibration signal generated by the blood flow brought by the human heartbeat can be transmitted through the human body and the vehicle structure. Since the background vibration signal generated when the vehicle is unmanned and the vibration signal generated when the vehicle is occupied have different power levels within a certain frequency range, the vibration sensor attached to the vehicle body or compartment is used to receive the vibration signal of the vehicle , and then compare the me...
