Best way to save realsense data without losing information

[uddhavbhattarai]

With realsense viewer I am able to save snapshot from different sensors individually and also .bag file to save all the information as video. How can I safe all images and ply files in disk at once? I am using D435.

If you tried to save all image and ply data in realtime, the performance of the stream would likely be very poor due to the processing load. It may be better to store the entire captured data in memory and then perform saving of the frames and any postprocessing at the end in a single action before exiting.

The Librealsense team created a function called Keep() for this kind of memory storage.

Writing to PLY is very slow.
Best way to save realsense data without losing information would be the ROS-bag format.
Our built-in recorder will collect everything you need, and it is fairly well optimized, at least when running in Release.
You can then extract individual frames / models as a post-processing step.
