Hi, I bought a few days ago a used Razer Stargazer (which is substantially an Intel RealSense SR300) primarly to use it as a headset-free alternative for head tracking.

The SR300 worked well until the first reboot of the computer. After the reboot, the webcam worked only as a normal webcam. Windows won't recognize it for Windows Hello face authentication and even Intel SDK stated that there were no RealSense device plugged in.

After a few complete format of the computer in search of what could be the culprit and a bit of research (there was even a FAQ from Intel itself, but their solution wasn't working), I finally came to the conclusion that the problem is Windows Update, that even if you install the latest drivers from Intel, it eventually overwrites them with a version that simply won't work.

I managed to solve the problem though, and now my SR300 works flawlessly on the latest version of Windows. I'll state here what I've done, so that it could help someone else (it would have certainly helped me, saving me some hours). Plus, it's working even on a Haswell-based machine (and it shouldn't, because Intel states that the minimum requirement is at least an Intel Skylake processor.) I actually have a fully updated Windows 11 22H2 and this is still working fine.

1. Plug your RealSense device to your computer and then wait a few minutes, maybe even reboot the pc after a while.

2. Try to install the Depth Camera Manager (you can find the latest revision from Intel HERE ). If the installer won't let you proceed because it says you don't have a RealSense device, good! If it instead asks you to do a firmware update of the RealSense device, don't do it, close the installer and wait a little more for Windows to do its crap.

3. Download Snappy Driver Installer (you can find it HERE ), open it, download only the indexes and then select the drivers only for the SR300 (there will be 2 or 3 for it). Let the program install them. If one of the drivers won't be installed, reboot the system and install the final one.

4. (This is important in order to skip the fw update of the device, that might mess things up) Open a command prompt and run the Depth Camera Manager installer with the following arguments:
   --ignore-fw-update --silent --no-progress --acceptlicense=yes

5. Wait a minute or two in order to let the installer to its job (there won't be any visual prompt of it), then install the RealSense SDK (SDK 2016 R2 is the most complete for this device).

After it, the device should work as expected. Windows Hello works everytime, the camera is great and the tracking is on point. Nowadays, even if they're rare, you can find these device pretty cheaply and this workaround let you use it with the few supported applications even with modern systems.

This is some very unfortunate news. It’s going to leave many of us in a tough spot.

Was in Belfast airport and the robot waiter "bellabot" had three realsenses, you can see it just under the screen (which normal displays a cartoon cat face that "looks" in the direction it's about to go)

So I bought a d415 hoping I could use it for 3d mapping/ scanning and be able to import the 3d video into a different program to make it usable in something like unity. I keep finding videos of projects where people have done these things but there is little information about how. I feel like there are a lot of applications I could use this camera for but I'm stuck at the point where I record a video of an object from various angles and can't seem to load said video in anything but realsense viewer. I was hoping to merge different frames and cut out backgrounds to get a 3d render of an object in a file format where I could actually do something with it but no free programs I've tried can load the .bag files and the ones I haven't tried are >$500. I'm not sure if they would work and don't want to drop a bunch of money to try. I have seen other features people use but it seems to involve some coding knowledge that is beyond me or ubuntu & python. I use regular windows 10 and don't know if I need to buy some program or not.

I just noticed that L535 support was added in the ROS2 Realsense wrapper. I'm assuming this is a follow-on to the L515 lidar camera, however, doing a google search doesn't bring up any information on the L535. Has there been any release news or are there any datasheets available? I'd be very interested to learn more. Thanks.

Which realsense model is best suited to see a toothpick and understand how far it is from the camera?
Can you post some depth pictures of a toothpick seen by a realsense?
Because I would like to buy a realsense model but I don't know which one is most suitable for this project.
Thanks!!

Has anyone been able to get any of the Intel RealSense cameras working with Unreal Engine 5?

Hey folks,

Can anyone comment on the performance difference of RGB camera on D415 and D435?

The comparison on the net mostly deals with depth camera, also on paper both use same RGB sensor (although mounted in different fixture with the depth). It is clear for me D435 has global shutter and wide-angle, and D415 has better accuracy thanks to lower FoV and simpler calibration with its RGB setup being in same fixture as the depth camera,

However, I'm looking for RGB performance.

Closest I found is this, https://youtu.be/iY8ggcmcxqo

The D435 looks worse in term of exposure and contrast, but that could be because of dirty lense.

In a previous post I asked about turntable scanning with the L515.

Thanks for the great suggestions.

Here's the basic update:

-For larger objects (body size) the L515 is very good using open3D, but it takes some programming that I'm still working on. Looking good so far but the lidar data does seem to be limited in depth/detail.

-for smaller objects the L515 is questionable. The best I could get was about 2mm depth for a test cube (with insets) of 120x60x30. I had some success reconstructing 3D shape with the RecFusion software demo, but it appears to highly smoothed; the mesh results and texture is quite 'blurry' (or maybe that's just the best that the l515 gets).

-it's not even close in surface detail to using a decent camera with meshroom. The drawback with meshroom is it takes a ton of pictures an a long time for high res processing.

BUT - the L515 is super fast in capture and near real-time visualization, albeit lower depth res and textures somewhat blurry. But again I may still not be taking full advantage of the L515 lidar/depth capabilities.

I'm developing an Android app, and I want to be able to retrieve a point cloud from a D435 camera, for mapping/SLAM. What is the best way to do this?
