Hi @adinathkale01 If the problem happening during the day then the camera may have froze if pointed directly at a strong light source such as the sun. This occures because the infrared sensors become saturated with light.

If this happens then, if auto-exposure is enabled, the camera should automatically recover when the camera is turned away from the light source or you cover the front of the camera with your hand for several seconds.

You should be able to also use the camera at night if the camera's infrared dot pattern projection is enabled.

does speed ,hand movement or sudden turn affect on mapping or not

[MartyG-RealSense]

D455 has sensors that are good at capturing depth during fast turns or motion. Quick turns are more likely to negatively affect the IMU (gyro and accel) rather than depth.

Hi @adinathkale01 Do you require further assistance with this case, please? Thanks!
