We are using two Intel Realsense Depth Cameras D435i for capturing the synchronous frames.
Trying to capture the same picture of the milli second timer running on our mobile camera with both the cameras while applying the external sync signal.
Our understanding is that both the camera's will capture the frame at the same time at the rising edge of the external sync pulse (>100uS pulsewidth)
We could set RealSense devices into different modes (Master, Slave, Full Slave, GenLock) easily but we couldn't able to capture the images at the same time on both the cameras with an accuracy of few milli seconds either with internal / external sync signal.
Always we are observing a difference of 50 to 100 milli seconds in the captured mobile timer image when cameras are set with 6FPS.
There are some whitepapers available in the Intel website and we are exactly sending the external sync signal inline with the website details yet we couldn't able to capture the frames from two cameras at the same time.
Could some one help us to understand the exact method to capture the synchronous frames using the external sync signal.
