Vehicle underbody imaging system
First Claim
1. A system for imaging the underbody of a moving vehicle comprising:
- a stationary source of radiation adjacent to radiate energy upwardly on an underbody of a moving vehicle;
a stationary video camera adjacent said stationary radiation source having an upwardly facing field of view for creating image signals representative of sequential portions of said underbody of said moving vehicle passing overhead;
a control station coupled for activating said camera and radiation source to create said image signals, said control station receiving said image signals from said video camera for creating mosaic signals of said underbody;
a screen coupled to said control station for displaying a mosaic image of said underbody from said mosaic signals, said control station including a computer activating said radiation source to radiate said energy and said camera to create said image signals, said computer creating said mosaic signals for said screen and storing a copy thereof, and said computer having memory to store earlier mosaic signals of previously taken mosaic images of the underbody of the same vehicle and vehicle manufacturers'"'"' data for the same vehicular model for comparison with said copy; and
a housing having elongate channels between ridges extending the length of said housing and an elongate hinged lid extending the length of said housing to cover said channels and ridges, said housing containing said stationary camera and said radiation source in said channels, said housing being placed on the center portion of a roadway between the areas where tires of vehicles normally roll, and said housing, said hinged lid, and said ridges protecting said stationary camera and said radiation source in said channels from said moving vehicle and other vehicles.

Abstract
A system and method for imaging underbodies of moving vehicles have a stationary source of radiation to radiate energy upwardly on underbodies of moving vehicles. A stationary video camera adjacent the radiation source on a roadway has an upwardly facing field of view for creating image signals representative of sequential portions of each underbody as each moving vehicle passes overhead. A control station activates the camera and radiation source to create the image signals and creates mosaic signals of all of each underbody from the image signals. A display screen provides a mosaic image of each underbody from its mosaic signals. A virtually real-time inspection or a comparison can be made with previously taken underbody images of the same moving vehicle or with vehicle manufacturers'"'"' data for the same vehicular models. Moving cars, trucks, marine vessels, aircraft, can be quickly imaged for inspection and/or comparison by fewer security personnel.

17. A method of imaging the underbody of a moving vehicle comprising the steps of:
-
radiating energy upwardly on an underbody of a moving vehicle, said step of radiating includes the step of; placing a stationary source of radiation to radiate upwardly; creating image signals representative of sequential portions of said moving vehicle'"'"'s underbody passing overhead said step of creating image signals includes the step of; facing upwardly a stationary video camera having a field of view extending the width of said vehicle passing overhead, said stationary video camera being adjacent said radiation source; activating said radiation source and video camera to create said image signals; creating mosaic signals of all of said underbody from said image signals from said video camera; displaying a mosaic image of said underbody from said mosaic signals; storing a copy of said mosaic signals, said steps of activating said radiation source and camera, creating mosaic signals and storing said copy being done by a computer coupled to said radiation source and said camera and said step of displaying being on a graphic display screen; storing in said computer earlier mosaic signals of previously taken mosaic images of the underbody of the same vehicle and vehicle manufacturers'"'"' data for the same vehicular model; comparing in said computer said copy of said mosaic signals and said earlier mosaic signals; and protecting said stationary camera and said radiation source from said moving vehicle in elongate channels between ridges extending the length of an elongate housing placed on the center portion of a roadway between the areas where tires of vehicles normally roll, said housing having an elongate hinged protective lid to cover said channels and ridges. - View Dependent Claims (18, 19, 20, 21, 22, 24, 25, 26, 27, 28, 29, 30, 31)
