Zooming with the IR Imagers of the RealSense D435

Follow
Michael Harder

We have multiple Intel RealSense D435 cameras. For a project we are streaming the video of one of the two IR imagers. We have to use the imagers, because we also need to analyze the IR part.

Does the IR imagers of the D435 support digital zoom in any way? If yes, how can we achieve that with openCV and pyrealsense2?

    Hi Michael Harder  The sensors or the RealSense SDK do not have a built-in zoom feature for infrared (depth pointclouds can be zoomed with code).  If you are able to use OpenCV though then a possibility may be to convert the RealSense infrared frame to an OpenCV mat and then use OpenCV code to zoom, like in the Python tutorial at the link below.

    The default interpolation setting of cv2.INTER_LINEAR is recommended for zooming.
