For thermal roof inspections with a Matrice drone, fly about an hour after sunset for best thermal contrast. Use a consistent flight path with good image overlap for stitching. Cameras like the Zenmuse XT2 or H20T are ideal. Capture radiometric images for detailed analysis with software like FLIR Tools. Mark locations during video if you use that method. Using GPS/RTK helps pinpoint defects accurately. This method is efficient and reliable.
