Recently, due to the instability of the international situation, car bombings against major buildings and people have occurred frequently, and rapidly developing technologies and equipment have been leaked.

Accordingly, vehicle underbody inspection devices, which are devices that search the underside of a vehicle when entering or exiting public parking facilities provided at major institutions, large shopping malls, event halls, and sports facilities, are being proposed.

Searching through an under-vehicle search scope, which is one of these under-vehicle inspection devices, cannot provide an accurate search due to blind spots, and the management personnel must carry the vehicle in person to stop the entering vehicle and then conduct a search one by one. In large facilities with a large influx of people, it takes a lot of time to search under the vehicle, causing inconvenience to users.

To solve this problem, a vehicle underbody inspection device captures image information by filming the underside of the vehicle through a camera, then reads the acquired undervehicle image information to detect bombs, drugs, contraband, etc. attached to the underside of the vehicle (patent document) 1) was proposed.

Therefore, if the overall length of the vehicle is a short vehicle such as a passenger car, the entire underbody area of the vehicle can be photographed. In the case of long vehicles such as , there is a problem in that the entire lower area of the vehicle cannot be photographed.

This is explained in detail using drawings as follows.

Figure 4 is a diagram showing different lower heights depending on the overall width and overall length of the vehicle. Typically, vehicles are passenger cars (C1) with a short overall length or overall width, and SUVs with overall length or overall width generally longer than passenger cars (C1). (C2) and overall length and width are generally longer than passenger cars (C1) or SUVs (C2), so they can be classified as large vehicles (C3), including buses and specially equipped vehicles.

The bottom height according to the overall length and width of the vehicle is generally lower than that of a passenger car (C1) (LH1), and that of a large vehicle (C3) is lower than that of a passenger car (C2). It is higher than the lower height (LH1) of (C1) and the lower height (LH2) of SUV (C2).

Such differences are subdivided by model of each vehicle and stored and managed in the information storage unit 510.
