3. Post-processing filters in C: leak and segmentation fault

wait_for_frames() is a mechanism for blocking until a complete frame arrives.  poll_for_frames() delivers the frames immediately, though the timing of CPU sleep periods has to be managed or the CPU...

That is my understanding (increasing the frame queue value increases latency, so frame-loss becomes less likely but memory consumption increases). https://dev.intelrealsense.com/docs/frame-manageme...

3. Post-processing filters in C: leak and segmentation fault

When post-processing alters a frame, the original frame is preserved and a new copy of the frame is created, so you have two versions of the same frame in the frame queue.  As new frames enter the ...

3. Post-processing filters in C: leak and segmentation fault

Dorodnic has also recommended not changing the frame queue from its default of '1' due to the risk of accidentally breaking streams with an incorrect value.  '2' could be used if streaming depth an...

I believe that depth_to_disparity converts depth data into a disparity map, and disparity_to_depth converts a disparity map to depth data.   https://support.intelrealsense.com/hc/en-us/community/po...

decimation -> hole filling -> threshold -> colorizer is a good mix of filters.  The threshold filter sets a minimum and maximum for the distances from the camera that depth is rendered at, and excl...

3. Post-processing filters in C: leak and segmentation fault

Post-processing filters are processed on the computer and not in the camera hardware, so having most or all of them enabled would have an impact on performance.  For example, Dorodnic the RealSense...

3. How to get the same timestamp data from two cameras

I recall a past case where a RealSense user was getting only noise from a pin instead of a clear sync signal because they were measuring Pin 1 instead of Pin 5 (the sync pin). https://community.int...

As well as setting the Master camera to '1' in the RealSense Viewer, have you also used the Add Source button to add the two Slave cameras to the Viewer too (so that you have three cameras listed i...

Hi Fabrizio Dini  I should emphasise from the start that my pure C (not C++ or C#) knowledge is limited.  I will do my best to provide some useful insights though. Yes, releasing resources is impor...
