MULTI-SENSORS AND DIFFERENTIAL ABSORPTION LIDAR DATA FUSION

摘要

A method of acquiring data uses multiple sensors in an aircraft. The methodincludes the steps of: (a) turning ON a DIAL sensor to detect a target ofinterest during a first flight pass over a region of interest (ROI), whereinthe target of interest is a gas or oil pipeline leak; (b) detecting the targetof interest using the DIAL sensor; and (c) storing location of the detectedtarget in a look up table (LUT). The method also includes the steps of: (d)during a second flight pass over the ROI, triggering another sensor to turn ONat or about the location stored in the LUT; and (e) confirming presence of thetarget of interest using both ON-sensors. If necessary, a third flight passover the ROI is conducted and yet another sensor is triggered to turn ON at orabout the location stored in the LUT. Presence of the target of interest isconfirmed using all three ON-sensors.
