Dataset description

Mosaic REALMAP Demo dataset with 9114 images collected with panoramic camera with global shutter sensors. You can find more about full dataset in this article: Mosaic Prague REALMAP Each image has its position written in EXIF metadata populated from IMU device paired with the camera. Images from each sensor are electrically syncronized up to several nanoseconds and the whole device can be considered as a multicamera rig. Additional camera information, including .gpx track is attached here also. Camera calibration is provided in COLMAP compatible format.

COLMAP project example

Dataset contains a small COLMAP project example, including .db, project.ini and exported model. It also includes depth map project with extracted dense point cloud

TODO

Explain calibration format, share full .json calibration and visualization script
Provide imu2camera calibration, provided poses for all images
