    3. Strange FPS when enable both color and depth streams

    Sorry for my late reply, I used sensor.get_option(rs.option.frames_queue_size) to check the frames_queue_size and it returned 16. Therefore, I used sensor.set_option(rs.option.frames_queue_size, 2)...

    3. Strange FPS when enable both color and depth streams

    Hello MartyG,  I've read the article you posted, but I don't know how to check/change frame_queue capacity in python. It seems that frame_queue object does the same thing as pipeline object? Is the...

    3. Strange FPS when enable both color and depth streams

    Thanks for your reply, but my fps is set to 60, so the required minimum exposure time is 1000ms/60fps = 16.6ms And I've already set the exposure value to 78(=7.8ms). I think the exposure value is q...

    3. Align color and depth images

    Hello. MartyG, Thank you for your reply, but the size of bag file is too big, so it's not in my consideration. opencv can save depth image into PNG now, and use cv2.imread('xxx.png', cv2.IMREAD_UNC...

    3. D435 get timestamp of each frame

    I read that article before, and what confused me is where can I find the source code. It seems that I should choose the source code, then choose where to build the binaries, press "Configure" button.
