Slamcore Dataset Recorder

The Slamcore SDK enables you to record the camera and IMU data streams and store them under a dataset on disk, via the Slamcore Dataset Recorder application.

Note

It is possible to record a dataset whilst running live SLAM. See Usage - Dataset Recording while running SLAM for more information.

Usage

To record a dataset using your camera, run the following from a terminal window:

# Launch the Slamcore Dataset Recorder
$ slamcore_dataset_recorder

Application UI

Fig. 11 Slamcore Dataset Recorder - User Interface

To change the dataset’s destination directory, click on the folder icon Select Directory Button .

To record a dataset, press the red Record button Record Button or hit the space bar key. The application will display the duration of the current dataset recording.

To stop recording, press the blue Stop button Stop Button or hit the space bar key again. Once the dataset has been written to disk, the application will display a pop-up with the path to the recorded dataset directory, as in the figure below.

Warning

Do not close the application until the pop-up is displayed to ensure all data is written to disk.

Once written, the dataset can be used as input to other Slamcore software tools.

See Dataset Compressor on how to perform PNG compression in a recorded dataset and saves storage space on your machine.
