#### Dataset Format

Each scene is a folder containing one or more RGB-D video sequences. The folder contents are as follows:

* **camera-intrinsics.txt** - a text file with depth camera intrinsics (3x3 matrix in homogeneous coordinates)
* **seq-XX**
  * **frame-XXXXXX.color.png** - a 24-bit PNG RGB color image
  * **frame-XXXXXX.depth.png** - a 16-bit PNG depth image, aligned to its corresponding color image. Depth is saved in millimeters (mm). Invalid depth is set to 0.
  * **frame-XXXXXX.pose.txt** - a text file with the camera pose of the frame (camera-to-world, 4x4 matrix in homogeneous coordinates and in meters)
