D455 read temperature using C# API #14028

Hi, How can affect temperature to measurement accuracy? I have experienced a lot of noise or measurement variance when temperature temperature is high (maybe 50 or 60ºC). Thanks for your help. With regards, |

Hi @JuanDYB There is advice at #6870 (comment) for retrieving the ASIC and projector temperatures with C# code. The official recommended maximum internal temperature (ASIC / projector) is 35 degrees C. In real-world conditions you can likely go to 42 degrees C before problems with the image may start manifesting above that temperature. At 60 degrees C, a safety mechanism in the firmware driver will turn off the projector's laser to attempt to bring down the temperature, and whilst the camera will continue operating the quality of the depth image will typically reduce in the laser's absence, with more gaps and holes. The D455 camera model has a thermal compensation mechanism that is enabled by default and attempts to adjust the depth values to maintain their accuracy during variations in temperature. If you have further questions please do ask and I will follow up with you tomorrow. Good luck with the code! |

Hi! Thanks for your reply. I have been able to read temperature using your link. I was trying to red it from the Sensor but didn't works. But with the sensor object from the frameset in the loop it works well. With regards! |
