Upward looking D435i in the sun
I am using D435i pointing upwards on our mobile robot, and there are occasions that the robot is going in the sun for a certain period of time.
What kind of issues are considered to happen to D435i if the D435i remains the same pose for a few minutes without moving while being pointed at the sun?
Will it just cause the camera to reset as mentioned in
https://support.intelrealsense.com/hc/en-us/community/posts/360051755413-D435i-for-agricultural-use , or will it go as to damage the CMOS sensor?
Also, how can D435i be recovered from the reset status if the camera get reset and start streaming?

Hi Kota Mogami The imager component should not be damaged if it is pointed up directly at the sun but the imager may become saturated, causing the stream to freeze. Resetting the camera should correct the problem and restores the camera to normal operation.
If you anticipate the camera being pointed at the sun regularly, applying a physical filter called an ND filter over the camera lenses may help to avoid saturation. This is described in section 3.1 of Intel's white-paper document about optical filters.
Dorodnic the RealSense SDK Manager offers advice about resumption of streaming after a reset in the link below:

If you are creating your own application, you can automate reset by including a command called hardware_reset(), and set up conditions for when a reset is allowed to activate (for example, when more than 50% of the pixels on an image have zero depth).
