NII-CU Multispectral Aerial Person Detection Dataset
The National Institute of Informatics - Chiba University (NII-CU) Multispectral Aerial Person Detection Dataset consists of 5,880 pairs of aligned RGB+FIR (Far infrared) images captured from a drone flying at heights between 20 and 50 meters, with the cameras pointed at 45 degrees down. We applied lens distortion correction and a homography warping to align the thermal images with the RGB images. We then labeled the people visible on the images with rectangular bounding boxes. The footage shows a baseball field and surroundings in Chiba, Japan, recorded in January 2020.
*RGB images captured with a Zenmuse X3 (3840x2160)
*Thermal images captured with a FLIR Vue Pro 640 in White Hot palette (640x512 before alignment)
*RGB images are corrected for lens distortion
*Thermal images are corrected for lens distortion and warped to be aligned with RGB images
*Labels are provided in CSV format
