markit-rs-recorder 2.0.0

Realsense remote recorder

RealsenseRecorder

A set of Python scripts to operate Intel Realsense Cameras. By using multi-thread techniques, this script can record color + depth from up to 4 Realsense Cameras (2 x L515 and 2 x D435)

Command Line Usage

To Create and persist record configuration:

python -m markit_rs_recorder configure

To launch a remote record station that supports REST API

python -m markit_rs_recorder serve

To launch a remote record station that is calibrated

python -m markit_rs_recorder serve --calibration=path/to/calibration

Note: The calibration.json file is expected to be in the path/to/calibration directory. The calibration file can be generated by running python -m realsense_recorder calibrate

To run calibration

python -m markit_rs_recorder calibrate

To run post-processing

python -m markit_rs_recorder post_process --base_dir path/to/recording
