Thanks for contacting Intel customer support.
I apologize for the delay in answering your question.
Currently what you are looking to achieve cannot be done. This is because the the different sensors are not calibrated with each other and the SDK does not provide a way to input your own calibration. In addition the SDK does not provide a way to generate a depth frame (or point-cloud frame) from a 3rd party depth sensor.
Can you please describe the problem you are having with ambient light and the SR300?
Are you using the camera indoor or outdoors?
Let me remind you the SR300 is an indoor camera and the outdoor exposure may affect the camera performance.
