Abstract: A low-cost, portable and highly-mobile “speed bump” which incorporates a plurality of electronic cameras, illumination devices, and range finders. The system can be rapidly and temporarily deployed to achieve increased security at facilities and events likely to be terrorist targets, and at checkpoints to achieve an element of surprise to terrorists and smugglers. As a vehicle drives over the imaging speed bump, range finders measure the position of the vehicle wheels in order to properly mark the position at which various images are captured. Image frames are “stitched” together to form a complete image of the undercarriage for display to a guard, officer or soldier. Reference images for a particular make and model of vehicle, as well as previously captured images of a specific vehicle may be used to detect anomalies in the vehicle's undercarriage.
