Abstract

A method of monitoring utility lines with an aircraft. A first step involves equipping the aircraft with at least one dual sensor camera capable of concurrently capturing both thermal images and real time video images. A second step involves equipping the aircraft with at least one of a storage medium adapted to store the thermal images and the video images or a display medium capable of concurrently displaying the thermal images and the video images. A third step involves flying along a utility right of way concurrently capturing the thermal images and the video images with the dual sensor camera. A fourth step involves reviewing the thermal images for thermal anomalies and the video images for visual anomalies.

Claims

1. A method of monitoring utility lines with an aircraft, comprising the steps of:

equipping the aircraft with one dual sensor camera capable of concurrently capturing both thermal images and real time video images and having a resolution of at least 256×

256 pixels;

equipping the aircraft with at least one of a storage medium adapted to store the thermal images and the video images or a display medium capable of concurrently displaying the thermal images and the video images;

flying along a utility right of way concurrently capturing the thermal images and the video images with the dual sensor camera; and

reviewing the thermal images for thermal anomalies of loss or gain and the video images for visual anomalies.

2. The method of monitoring utility lines as defined in claim 1, the reviewing step involving concurrently viewing the thermal images and the video images on the display medium while the aircraft is in flight.

3. The method of monitoring utility lines as defined in claim 1, the reviewing step involving recording the thermal images and the video images to the storage medium during flight and concurrently viewing the thermal images and the video image subsequent to the aircraft being in flight.

4. The method of monitoring utility lines as defined in claim 1, including the further step of equipping the aircraft with a supplementary sensor which provides a supplemental warning of the existence of anomalies.

5. The method of monitoring utility lines as defined in claim 4, the supplemental warning being in the form of an audible alarm.

6. The method of monitoring utility lines as defined in claim 4, the supplemental warning being concurrently displayed as one of a numeric or a graphic output image created from data provided by the supplementary sensor.

7. The method of monitoring utility lines as defined in claim 4, the supplementary sensor being a hydrocarbon analyser.
