Abstract

A surface scanning method and apparatus attached to a highway vehicle, mobile equipment, or the like, that traverses existing roadways and bridges. The apparatus has at least one of a variously adaptable, complete, and ready to operate packaged kit including configured sensor suites with one or more of a visual scanning sensor; an infra-red scanning sensor; and an elevation measuring sensor.

Claims

1. A surface and sub-surface scanning apparatus attachable to a highway vehicle, mobile equipment, or the like, that traverses a structure to be evaluated, the apparatus including at least one of a variously adaptable, and ready to operate packaged kit including a detachable and adjustable structural boom assembly that supports configured sensor suites with one or more of a visual scanning sensor, an infra-red scanning sensor, at least one GPS antenna and an elevation measuring sensor, wherein

the visual scanning sensor comprises a high-definition visible band camera for capturing surface images of the structure to be evaluated;

the infra-red scanning sensor comprises a high-definition infrared band camera for sub-surface observation;

the at least one GPS antenna enables real-time recording of vehicle position, speed, and direction with respect to actual position coordinates and ensures synergistic timing between image collection and geographic positioning;

the structural boom assembly is attachable to a front, a rear or a side of the vehicle, thus enabling the high-definition visible band camera and infrared scanning sensor to be mounted at a desired elevation above the structure to be scanned to achieve a desired field of view (FOV), the field of view (FOV) being preferably approximately at least one traffic lane in width; and

the elevation measuring sensor comprises an electronic laser range finder for measuring the height of the high-definition visible band camera and scanning sensor above the structure to be scanned, the electronic laser range finder providing a reference signal for calibration and correction factors related to the height and data signals received by the high-definition infrared band camera and visible band camera.

2. The surface and sub-surface scanning apparatus of claim 1, wherein the vehicle operates at nominal highway speeds and preferably at a general magnitude of travel velocity in the range of 50 miles per hour (80 kilometers per hour), whereby roadway lane and bridge closures, the re-routing of traffic onto alternate routes, the slowing of normal vehicle traffic, or otherwise significant interruptions to the normal and safe flow of traffic and vehicles are at least partially or entirely eliminated.

3. The surface and sub-surface scanning apparatus of claim 1, wherein the visual scanning sensor, the intra-red scanning sensor, or both, scan perpendicularly in relation to the structure to be scanned.

4. The surface and sub-surface scanning apparatus of claim 1, also including a computer for processing measurements and video data signals collected by the vehicle-mounted high-definition visible and infrared band cameras.

5. The surface and sub-surface scanning apparatus of claim 4, wherein the computer further includes a high-speed processor and software for rapid integration of video data signals collected by the vehicle-mounted high-definition visible and infrared band cameras.

6. The surface and sub-surface scanning apparatus of claim 5, wherein the computer and high-speed processor further include a digital storage device whereby recorded data and signal outputs are stored.

7. The surface and sub-surface scanning apparatus of claim 6, wherein the computer and high-speed processor further include software programs whereby the recorded data and signal outputs are further processed and formatted for output and analysis.

8. The surface and sub-surface scanning apparatus of claim 7, wherein the scanning apparatus and kit further include at least one output monitor for displaying output information so that the operator may visualize an internal structural condition of material below the surface scanned, thus allowing the operator to identify and locate structural defects and features apart from those representative of superficial, or nonstructural defects of the scanned surfaces.

9. The surface and sub-surface scanning apparatus of claim 8, wherein the computer generates an output format consistent with quantitative data related to a calculated percentage of structural defects and their respectively defined physical locations with respect to GPS standards in accordance with customer-defined specifications, the transportation industry, and/or respective governing body standards.

11. The surface and sub-surface scanning apparatus of claim 5, further including at least one output monitor for displaying an output of the software such that an operator may visualize the internal structural condition of material below the surfaces scanned, thereby allowing the operator to identify and locate such structural defects and features apart from images from the visible band camera representing superficial, or nonstructural defects of the scanned surfaces.

10. A method for evaluating surface and sub-surface conditions of underlying infrastructure, the method comprising the steps of providing, not necessarily in the order listed:

a vehicle-mounted high-definition visible band camera for capturing images of the surface to be evaluated;

a vehicle-mounted high-definition infrared band camera for sub-surface observation;

a detachable and adjustable structural boom assembly attached to a front, side or rear of the vehicle whereby the high-definition visible and infrared cameras are remotely mounted at a desired height vertically above the surface to be scanned so as to encompass a desired field of view (FOV), the FOV being preferably approximately at least one traffic lane in width or more of a portion of the structure to be evaluated;

an electronic laser range finder for measuring the height of the high-definition visible and infrared band cameras above the surface to be scanned;

at least one GPS antenna for real-time recording of vehicle position, speed, and direction with respect to actual latitude and longitude coordinates; and

a computer for digitally processing measurements and video data signals collected by the high-definition visible and infrared band cameras.
