How to start proprely on Unity ?
Hello, I recently bought a D455 to use it in the development of a facial recognition application on Unity.
Nevertheless, it is very difficult for me to find simple and effective tutorials that allow the setting up of a workspace on Unity.
Are there any videos or clear and efficient tutorials that show the steps to follow? I have followed some but I often have either bugs or an inability to follow the steps.
I have already worked on the application using my phone, and I would just like to transpose the RealSense technology into my already existing project if possible.
For confirmation, I use Unity 2020.3.15f2.
Thank you for taking the time to answer me.

Is the camera still undetected in the Viewer if you unplug the USB cable from the side of the camera at the micro-sized end (instead of unplugging from the computer), wait a couple of seconds and plug the micro-sized connector back into the side of the camera?
Also, does the camera remain undetected if you unplug the micro-sized connector from the camera, turn the connector around the opposite way and re-insert it (as USB-C cables are two-way insertion at the micro-sized end)

Thanks very much for your continued patience. Next, let's test whether your computer has a conflict with recent versions of the RealSense SDK. Please download and run the standalone version of the RealSense Viewer - Intel.RealSense.SDK.exe - from the old 2.40.0 version of the SDK to see whether that Viewer version can detect the camera.
https://github.com/IntelRealSense/librealsense/releases/tag/v2.40.0
Once downloaded, the file should be launched with a double-leftclick from the location on your computer that it was downloaded to and not with the Viewer shortcut launch icon on the Windows desktop.
-
All of the programs that have not been able to detect the camera have been part of the RealSense SDK (RealSense Viewer, RealSense Unity wrapper, rs-capture, rs-hello-realsense, etc). It may therefore be worth trying a software program that is compatible with the D455 but not part of the RealSense SDK in order to confirm whether a non-SDK program can use the depth sensing functions on your computer.
There is a commercial 3D scanning tool called DotProduct Dot3D Lite that is D455-compatible and has a free trial version for Windows.

I've made the free trial and it doesnt reconize it either but when i unplug the camera et replug it it doesnt have a 1sec loading that doesnt not happen if i unplug/plug other usb like mouse or keyboard.....
In my opinion in doesnt mean that it reconize it as a camera device but for a unknow reason it doesnt conider it as "supported device".

Thanks very much for testing. The number of remaining possible solutions is narrowing, unfortunately.
If the issue is with the USB controllers that handle your computer's built-in USB ports (you mentioned that they were only USB 3.0) then attaching the camera to a USB hub would mean that the hub would use its own USB controller that was different to the one used on the computer's built-in ports.
Though there does not appear to be a problem with the firmware driver of the camera, it may be worth updating the driver in the RealSense Viewer on the other PC that you have access to and then taking the camera back to your own PC (since the firmware update would be carried back to your machine as it is stored inside the camera).

Hello, i've made a lot of test before responding to you.
We the help of friends, I've tested 5 different pc (including my own and my brother pc) and i find suprising result:
There's 3 normal PC tested and 2 Laptop (Dell laptop).
-In my pc, the camera is detected and can be used as a webcam but has never been detected by either realsense viewer or unity and here's my setup: https://ibb.co/SnhWJd7
-My brother pc (the one i've tested before and told you it woked) that reconize it in realsense viewer and here's his setup: https://ibb.co/GWTF5Yr
-The third normal pc that reconize it but doesnt reconize it in realsense and in which the camera was extremly buggy when used on messenger: https://ibb.co/mqsnPhs
-A laptop that reconize it on realsense viewer but is still have the visual "bugs": https://ibb.co/Mgb08d7
-A laptop that reconize it on realsense viewer and seems to work perfectly: https://ibb.co/Msy0Wth portable
The common point between the laptops is the fact that they're "newer" and use10th+ generation of intel processor.
I wonder if the problem isn't about that...
But my brother pc is very old and not "great" compare to my setup or the third pc setup....
I am really lost in this situation and i've 3 different ideas about the actual problem and you tell me which one is possible please:
-Video card is interfering with the process.
-The motherboad isn't "good" enough and old or something like that (it's weird because my borther one is pretty old too).
-The camera have bugs and i should change it.
The last idea I have is to potentially change the version of the camera (take a 435 or 415 for example) to solve this problem since I will use this camera in a short range.
Do you think it could solve the problems encountered? -
The age of the processor should not be a factor with 400 Series cameras, as they can work with any Intel or Arm processor.
If the camera works fine on your brother's PC then it is likely that the camera hardware and the firmware driver are okay.
The model of the camera should not be a factor in whether it is detected or not.
It does not look as though the PC that has 'visual bugs' actually has problems. The image shown is the Viewer's 3D pointcloud mode, which renders the camera data differently from the Viewer's 2D mode. A 3D pointcloud typically looks more 'broken' than the multi-colored depth images in the 2D mode. The '2D' and '3D' options in the top corner of the Viewer highlight in blue lettering which of the two modes are currently active.
In past cases where the camera works fine with some computers but not others, the suspicion for the cause has typically been focused on the computer's operating system.
In one such case, two colleagues were using the same model of PC, but one worked fine and the other had problems. Eventually it was found that the colleague whose PC worked had updated the Ubuntu operating system on his computer and so had more recent drivers. Once the person with the problem updated their computer too to match the configuration of the colleague's computer then the problem disappeared.
This kind of problem is difficult to diagnose because it is hard to tell the differences between the OS configurations of different PCs. For example, Windows may download and install updates that are not on another PC that is using Windows.

Hi, I'm here to share the latest news:
After testing it on several PCs, I decided to change my motherboard to get (I hoped) a different result.
unfortunately, always the same problem with an Asus or gigabyte motherboard....
I would like to call on you again to debug my situation because it's honestly becoming very painful.
You say that regardless of the material it works and that my configuration has no problem but at the same time the problem is that it does not work at all, so there is a problem, I bought a camera that several hundred euros that I can not use :/ .The camera is detected in some PCs and not in others, I need to understand the problem (hardware, logistics ....)
Can you please find out more and try to help me solve this problem once and for all? -
As mentioned earlier in this discussion, even if the camera hardware is fine the camera may work on some PCs but not others. Reasons for this could include a problem on the USB ports of the computer or with the computer's operating system and updates that it has installed. As you have changed your motherboard though and it still does not work, this suggests that the problem is not with the USB ports.
You have already tried disabling your antivirus software in case it might have been blocking the camera.
Are you able to wipe your hard drive and do a complete fresh re-install of Windows, or is this something that you would rather not attempt?
To eliminate the possibility that Windows power-saving on the USB ports is blocking your camera, please try setting the USB sleep aspect of your Windows power plan to 'disabled' using the instructions in the link below.

Hi, I tried to reinstall my Windows on the PC without success ....
I also used a Ubuntu virtual machine to see if the problem was coming from my Windows.
But still nothing, doesn't this information give you more understanding about the problem?
If yes, do you think that Cloud Pc (such as GeForce Now, ....) could be an interesting solution to use the camera? -
If you were accessing Ubuntu on the same computer as the Windows OS by using Windows Subsystem for Linux (WSL) then this would not work due to WSL not being able to use a USB device and therefore not being able to access the RealSense camera.
If you have another PC, you could consider using a remote computer control system such as Google's Chrome Remote Desktop tool to have the camera running on the other computer and control that computer from the Windows machine as though you were using the Ubuntu computer directly.
https://remotedesktop.google.com/
For virtual machines, Intel recommend using VMWare Workstation Player (Workstation Pro should also work) so that USB 3 support is provided.
Another way to access a camera attached to a computer / computing device with Ubuntu installed from a Windows 'host' PC would be to set up an ethernet system. This treats the RealSense camera as a network camera instead of one that is directly attached to the host computer.
I am not aware of a previous case of using RealSense with a cloud PC or a computer with a cloud OS such as Chromebook and so do not have advice to offer regarding whether it could work.

Thank you for your help so far, however not all solutions work.
I would like if you can organize a call on zoom or a platform of your choice so that we can study the problem together with a screen share from me.
The problem has lasted too long and I would like to put an end to it. I bought your most recent model and I would have liked to buy more if my development would have been finished. -
Hello, I hope you are well. First of all I would like to thank you for the help you have given me during the last months.
After several weeks/months of struggle to get the camera working on my personal computer I would like to inform you that there has been no progress on this side despite the dozens of hours and effort I have put into it.
I have logically asked for a refund on the product but the seller asked me for the RMA (Return merchandise authorization) that I am supposed to obtain from you. I hope I can get it so that the return goes smoothly. -
Hi Youcefbouzgaou The earlier comment in this support discussion at the link below indicated that the problem was related to specific computers rather than the camera hardware, since the camera was able to work perfectly on at least one computer.

I am not involved in camera returns / refunds on this Intel RealSense Customer Support forum, as I am from a different RealSense support team to the one on this site. I would recommend creating a new case on this forum using the New Post button on the front page of the forum and make your request for RMA in that case so that a team member of this forum can handle it. Please provide a link to this case here to demonstrate that the problem has been throroughly explored.
