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

Hardware sync causes the timestamps of the Slave cameras to try to follow the timing of the Master camera.  The slave cameras are still responsible for generating their own streams though - it does...

If I understand correctly, test 2 is mixing together the Dynamic Calibrator and the On-Chip Calibration systems: writing a calibration table with the Dynamic Calibrator, and then trying to read the...

Okay, thanks for checking.  Even if it were installed, your image showed that it is an earlier version of the UWP driver rather than the 6.11.160.21 one that can cause errors, so it may not be the ...

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...

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

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...
