Is there a way to know in real time the depth to the floor when the sensor is pointing from the ceiling to the floor?

I initially saved the depth value to an external file, but the value seems to change little by little. Is there another way?

Hello GenJu,
Thank you for your interest in Nuitrack! If we understand correctly, you can take a look at our samples. You could pass a callback function to depthSensor using connectOnNewFrame and get information in real time.
