Augmented Reality for UE4

Community Showcase Game Development

Hi , first of all thank you for creating a really well made AR plugin that works for Windows, most of them are Android/IOS only.
I have two questions:

  1. can I have 2 of the same type of markers on screen at once? For Examples 2 Hiros on screen.
  2. How do I set the Camera resolution to 1080p or 720p 30fps and have that setting save each time I play?

I am also really struggling to figure out how to get NFT markers working?
I’ve read through the doc, but it’s not very helpful in explaining how to actually test the Data set?

Thank you very much for your reply .

I’ve been doing some tests with these 3 nodes you recommended. What I could find out was that the set threshold mode and set threshold nodes have to do only with marker recognition by the camera in terms of brights and darks for easy recognition (good to have that, very useful) and the set filter node has more to do with the jittering or vibration at positioning the 3D models in relation to the marker position, but I can’t seem to soften the vibration in any way. Is there any other solution I can try to improve the vibration problem? By the way, I cannot increase the size of the marker due to the nature of the project, it needs to be in a certain place and not larger than a certain size to work for the purpose I am pursuing. Do you have any other suggestions?

Thank you very much.

Hello,

  1. No, you have to use different markers.

  2. You can set everything at startup when the “Show PIN” checkbox is checked.
    Init - AUGMENTED REALITY

My recommendation is to use only 4:3 resolutions like 800x600 or 960x720

  1. Please find all the required tools for creating NFT markers (genTexData.exe is located in the /bin folder)
    ARToolKit5.zip - Google Drive

To use the new NFT:

  • Put the generated files to Content/ARToolkit/DataNFT
  • Add the name of your marker to the MarkersNFT enumeration in the unreal editor.
  • Use this new name for the GetMarkersNFT node.

There should not be that much jitter, even with the default settings.

What is your framerate ?

Hi , thank you for the reply.

  1. With the marker tracking if I have multiple of the same marker on screen, it bugs out and doesn’t display a model on either of the markers until I remove both from the view.
    Is there a way to track the first marker, and keep tracking the first marker if another of the same type is added to the view?

  2. This setting does not Save, and I have to go through the checkbox every time, which I do not want, I want to be able to set up the parameters once.
    How I can set web camera source parameters?

  • Resolution
  • FPS
  • Video Format
  • Color Space
  1. Thank you, I managed to get that working :slight_smile:

The current setup doesn’t allow that.

Camera settings are not exposed for blueprints.

In the source code ARToolkitDevice.cpp line 548

[FONT=courier new]config << “-devNum=” << devNum<<" -flipV ";

You can add other options after the “-flipV” argument according to the docs

Theoretically it should work, but I had no luck with my logitech webcam.

Hello All, I’m still struggling with this - everything is working fine except the people im showing this project to want the model stay on the market when I move away from it and not disappear. Any ideas?

Otherwise this plugin is fantastic!!!

Hi good day; I have the commercial version 1_16 for UE4_24.3, but when creating the project the editor gives me an error that the ARToolkitPlugin module is missing, it recommends rebuilt, but doing so gives me an error that it must be done manually but the truth I don’t know what I could do, I hope you can help me; Have a great day.

1238

Hi - this looks like a great plugin - do you have a trial so we can verify the functionality is giving us what we want and do you have a version updated for 4.25 yet?
