Abstract

In accordance with at least one embodiment of the present invention, a portable inspection system is disclosed to wirelessly capture inspection data, such as for example an infrared image, sound information, and/or electrical measurement information. The inspection data may be securely recorded (e.g., with an encryption algorithm) along with associated information, which may include for example date, time, system settings, operator identification, and location.

Claims

1. A portable inspection system for inspecting a target in a scene, comprising:

an infrared camera comprising, within a housing, a multi-pixel infrared detector configured to receive infrared radiation from an area of the scene within a field of view (FOV) and to generate infrared image data of the area of the scene within the FOV;

a display configured to display viewable images;

a processor coupled to the infrared camera and the display and configured to process the infrared image data to view as an infrared image on the display;

one or more non-imaging sensors configured to detect one or more physical parameters associated with the target and to provide the one or more physical parameters to the processor; and

a boom having its distal end couplable to at least one of the one or more non-imaging sensors to position the at least one non-imaging sensor relative to the FOV of the multi-pixel infrared detector,

wherein one of the one or more non-imaging sensors comprises a plurality of microphones configured to capture stereoscopic sound data from the scene and to provide the stereoscopic sound data to the processor, and wherein the processor is adapted to analyze the stereoscopic sound data to determine a location of a gas leak from the scene and to associate the location of the gas leak with the infrared image data.

2. The portable inspection system of claim 1, wherein the processor is further configured to provide visual cues based on the stereoscopic sound data to the display to direct a user of the portable inspection system to the location of the gas leak.

3. The portable inspection system of claim 1, wherein at least one of the one or more non-imaging sensors is configured to wirelessly communicate with the processor.

4. The portable inspection system of claim 1, wherein the boom is couplable to the housing of the infrared camera and configured to selectively position the at least one of the one or more non-imaging sensors within or out of the FOV of the multi-pixel infrared detector.

5. The portable inspection system of claim 1, wherein the one or more non-imaging sensors comprise a gas measurement device configured to detect a presence and/or a concentration of at least one gas in a vicinity of the target to provide gas detection and/or concentration information to the processor.

6. The portable inspection system of claim 1, wherein the non-imaging one or more sensors comprise an electrical measurement device configured to measure electrical current, voltage, and/or resistance to provide electrical measurement information to the processor.

7. A portable inspection system for inspecting a target in a scene, comprising:

an infrared camera comprising, within a housing, a multi-pixel infrared detector configured to receive infrared radiation from an area of the scene within a field of view (FOV) and to generate infrared image data of the area of the scene within the FOV;

a display configured to display viewable images;

a processor coupled to the infrared camera and the display and configured to process the infrared image data to view as an infrared image on the display; and

one or more non-imaging sensors configured to detect one or more physical parameters associated with the target and to provide the one or more physical parameters to the processor,

wherein the one or more non-imaging sensors include a rangefinder configured to measure a distance to the target and to provide the distance measurement to the processor,

wherein the processor is adapted to compare the distance measurement with a safe distance range to the target to generate a safe distance perimeter indication for alerting a user of the portable inspection system,

and wherein the display is further configured to display the safe distance perimeter indication along with the infrared image on a screen for viewing by the user.

8. The portable inspection system of claim 7, wherein the display is further configured to display the distance measurement along with the infrared image, and wherein the safe distance perimeter indication is displayed as a color-coded warning corresponding to a degree of hazard to the user'"'"'s safety based on the distance measurement and the safe distance range.

9. The portable inspection system of claim 8, wherein the color-coded warning provides a first color to indicate a safe distance, a second color to indicate a minimum distance range, and a third color to indicate a less than safe minimum distance.

10. The portable inspection system of claim 7, further comprising a speaker coupled to the processor and configured to provide the safe distance perimeter indication as an audible warning.

11. The portable inspection system of claim 7, further comprising a data entry device configured to allow the user to enter information into the portable inspection system, wherein the safe distance range is received via the data entry device.

12. The portable inspection system of claim 7, further comprising a boom having its distal end couplable to at least one of the one or more non-imaging sensors to position the at least one non-imaging sensor relative to the FOV of the multi-pixel infrared detector.
