Suggestion for real sense model to buy
Dear community,
I am developing an object that will be mounted on a tractor, which needs to capture time-lapse photos.
I would like to know from your side which model you recommend me to purchase considering that:
1. I will use the camera outdoors on sunny days
2. The surface to be measured depth will be at most 5 meters away
3. Being that the photos will be acquired while the tractor is in motion, thus with vibrations and jerks due to potholes, with cameras like pi camera v3 generated me artifacts due to motion, so I would like the real sense camera to be able to acquire RGB photos in global shutter and that I can change the exposure time and other parameters that we need to be able to frizz the image.

Hello, the RealSense D455f model would be suited to your needs.
- It has a global shutter on both the depth and RGB sensors that handles fast motion very well
- It retains depth measurement accuracy over long distance, with 2x less error over distance than the D435 type model at 6 meters from the camera
- It is equipped with a filter on its depth sensors for better performance in strong light conditions, which is where the 'f' in the model's name comes from
- A feature called Thermal Compensation can automatically adjust depth measurements to take account of variations in temperature that might cause depth error

In general, RealSense 400 Series perform excellently in strong light anyway, but the filter is are advantageous in situations where the camera is directly facing a strong light source such as the sun.
The depth sensing algorithm on all 400 Series cameras is also robust against vibration, making them very suitable for use on rough ground in agricultural applications. If vibration is severe though then you could consider adding vibration damping pads to the mounting point of the camera.

The cameras can be used with Raspberry Pi boards, including Pi 5. However, the full capabilities of the camera may not be able to be accessed on a Pi and the best that you may get is basic depth and RGB streams, with no IMU motion tracking data or the ability to use additional processing such as depth-to-color alignment or post-processing filters.

thank you very much for your answers, we are very interested in testing your camera.
If possible I would like to ask if there is a repository where we can take samples of photos with rgb and depth to see how it behaves with moving objects
also i would like to ask you if you have a photo stabilization system.
Thanks again for your cooperation

The YouTube video at the link below of a RealSense-mounted vehicle travelling on a road is a useful reference for the simultaneous depth and RGB capture capabilities of RealSense 400 Series cameras.

There are also official sample 'bag' camera recordings that can be played back in the free RealSense Viewer tool without having to have a real camera attached.

There is not a dedicated image stabilization mechanism, but you should be able to achieve a similar blur reduction effect by setting a high frames per second (FPS) frequency, such as 60 or 90 frames per second.
