How to separate the image of open RS2_OPTION_EMITTER_ON_OFF model?

  It looks as though your question is related to your previous question about alternating the projector on and off each frame, where it was suggested that you use the instruction RS2_OPTION_EMITTER_ON_OFF to do this.

  If you are asking whether you can check if the IR Emitter is enabled, I guess you could do that by checking if the value of RS2_OPTION_EMITTER_ON_OFF  = '1' (on).

  Another way to check if the emitter is enabled might be to get the value of RS2_OPTION_EMITTER_ENABLED: (where '0' is disabled and '1' is enabled).

  depth_sensor.get_option(RS2_OPTION_EMITTER_ENABLED)

  When RS2_OPTION_EMITTER_ON_OFF=1(on), ir is always on, RS2_OPTION_EMITTER_ENABLED is always 1 (enabled), but I want to distinguish whether the output image is speckled, just how to distinguish two images in my problem in the code.thank you very much.

  If your aim is to detect whether an image has speckles, OpenCV might be the best way to do it.  Google for 'opencv detect speckle'.  Here is an example:
