An output is generated if the fastener installed in the opening has the out of tolerance gap.

A method and a system for fast inspecting a vehicle based on a length measuring device, including: when a subject vehicle enters an inspection region, measuring a first length and a second length of the subject vehicle; determining whether the first length and the second length is respectively larger than or equal to a preset second length threshold; if so, determining whether a gap portion of the subject vehicle between a first portion and a second portion of the subject vehicle appears in a beam emitting region formed by a beam of radiation rays emitted by the system for fast inspecting a vehicle; and when the gap portion appears in the beam emitting region, emitting a beam of radiation rays of a first radiation dose to the subject vehicle according to the gap portion, wherein the subject vehicle moves with respect to the system for fast inspecting a vehicle.

A portable x-ray backscattering imaging system for creating a backscatter image representing an object is disclosed. The portable x-ray backscattering imaging system may include a drum, a radioactive source, a plurality of backscatter detectors, and a portable exterior shield. The drum may be rotatable about an axis of rotation at a rotational speed. The radioactive source may be connected to the drum and configured to generate x-rays. The plurality of backscatter detectors may be configured to detect backscattering radiation created as the x-rays generated by the radioactive source scatter back from the object. The portable exterior shield may enclose the drum. The exterior shield may be constructed of a material that substantially blocks the x-rays and defines a window that allows for the x-rays to pass through.

There is described a handheld inspection device for inspecting an infrastructure having a structure wall at least partially supported into material such as soil. The handheld inspection device generally has a portable frame; a high energy photon source mounted to said portable frame and having a radioactivity level below a threshold radioactivity level; a scattered photon detector mounted to said portable frame and having a field of view diverging towards said target region of said infrastructure and encompassing at least a portion thereof, said scattered photon detector detecting scatter events incoming from said target region during a given period of time, and generating a signal indicative of scatter events detected during said period of time; and a controller receiving said signal generated by said scattered photon detector; and generating an integrity indication associated to said target region of said infrastructure based on said received signal.

A vehicle inspection method and system are disclosed. In one aspect, the method includes acquiring a transmission image of an inspected vehicle. The method further includes acquiring a transmission image template of a vehicle model corresponding to the model of the inspected vehicle from a database. The method further includes performing registration on the transmission image of the inspected vehicle and the transmission image template. The method further includes determining a difference between a transmission image after the registration and a transmission image template after the registration, to obtain a difference area of the transmission image of the vehicle relative to the transmission image template. The method further includes processing the difference area to determine whether the vehicle carries a suspicious object or not. In some embodiments, this solution can avoid the problems of a detection loophole and a poor effect of manually determining an image in a conventional manner, and is important to assist the security inspection for small vehicles.
