Set-up
The set-up is composed of the following elements:
- Kinect: this consumer device provides standard (RGB) and Depth video streams at VGA resolution (640x480) and 30fps.
- HD camera: the Kinect was designed with a large field of view
imposing less restriction on user mobility but this is problematic for
eye tracking based on VGA resolution. Therefore, we also recorded the
scene with a full HD camera (1920x1080) at 25fps. The provided videos are synchronized with the Kinect data at 30fps.
- LEDs: 5 LEDs visible to both cameras were used to synchronize the RGB-D and HD streams.
- Flat screen: we used a 24" screen to display a visual target.
- Small ball: we used a 4cm diameter ball as a visual target with a
double purpose: to serve as a visual target in a 3D environment and be
discriminative in both RGB and depth data such that its 3D position
could be precisely tracked
This set-up was used for the recording of 94 sessions, each with different characteristics.
Data per session
At each session folder, the following files can be found:
- rgb_vga.mov : the RGB Kinect video. Encoded using MPEG-4.
- depth.mov : the Depth video. Encoded using ZLIB.
- rgb_hd.mov: the RGB HD video. Encoded using MPEG-4 (The HD video is not available for a few sessions).
- head_pose.txt : the frame-by-frame head pose parameters.
- eye_tracking.txt : the frame-by-frame 2D and 3D eyes position.
- ball_tracking.txt : the frame-by-frame 2D and 3D position of the ball target (if relevant).
- screen_coordinates.txt : the frame-by-frame 2D and 3D screen coordinates (if relevant).
- rgb_vga_calibration.txt: the calibration parameters for the RGB Kinect camera.
- depth_calibration.txt: the calibration parameters for the Depth camera.
- rgb_hd_calibration.txt: the calibration parameters for the RGB HD camera.
In total, the EYEDIAP database is composed of 94 sessions. For a list of the sessions, go here.
