How to copy stream from d4355, and use opencv draw lines and render the new stream.

  The first step would be to install the RealSense SDK's OpenCV compatibility 'wrapper' if you have not done so already.

  https://github.com/IntelRealSense/librealsense/tree/master/wrappers/opencv 

  Once the wrapper is set up, you can use the simple imshow sample program in the link below to render the depth stream.

  The OpenCV documentation page in the link below describes the basic instructions for drawing lines and text on an image.

  Hi MartyG:

           I would like to render new stream with GLFW. so I need function to create a new stream, this new stream's inputs are depth stream + opencv output. 

   

  Best Regards

  Fred

  There is a RealSense sample program for OpenCV called rs-kinfu that makes use of GLFW as a dependency to generate a point cloud.

  Hi MartyG:

         thanks for you kindly information. I have fix it. late I will learn rs-kinfu.

         By the way, could rs-kinfu support D435? My device is D435.

   

  Best Regards

  Fred

  Though the D435 has a wider field of view than the D415 and so there may be some minor differences in output in that respect, in most cases a program that works with D415 will work with D435.
