Augmented Reality for UE4

[AdamHorvath]

Hi,

I think you have to disable datasmith before publishing to iPad.

Hello - I purchased your plugin as I am very pleased. One thing - I'm using the latest unreal 4.24 - I can always get the sample to run with no problems.. The moment I enable DataSmith plugin - UE4 is ask to restart once I restart it and push the app to the IPAD - the app always crashes. Something about Plugin blastplugin failed to load because module BlastCore could not be found? Thats the message on the IPAD.

Any ideas?

Thanks I manage to get this working - One last question - I managed to change the model from the bike to a simple mesh when the image is detected - Is there away to keep the model (mesh) there on the image..... even after i move away from the image instead of it disappearing ?

Hi everyone.

How can you prevent the 3D model from shaking so much?

I have tried enabling and disabling the set filter node, playing with Sample Rate and Cut Off Freq values with no significant change.

What's the best way to get rid of the jittering? What else could I try to fix it?

Thank you.

Hello Carlos,

There are 3 nodes that can help. All the 3 has an example in the demo project, you can play with settings to find the best for your environment.

One more thing I see on your video is the small relative size of the marker. Try to go closer so the marker will be bigger.

I hope it helps.

Hello Adam,

I have a problem with calibrating my android tablet camera. I have installed an app on my tablett, and another one on my PC. So I can use my tablet as a webcam. So far so good.

I then use camera_calib.exe file for generating camera_para.dat file like it is described here:
http://www.daslhub.org/unlv/wiki/dok...nxt_ar_toolkit

I did it twice, but I am not happy with the result. All tracked marker (I took some squared control planes for checking) are 2D shifted against live camera stream.
Is there a way to edit camera_para.dat by hand ? Just to set a different "Point of Interest" or similar?
Calculated FOV seems to be ok, marker lines are parallel by any viewing angle but still not matching. (its 2D shifted)

There are other tools for generating camera_para.dat like described here:

Is this older or newer? Or even more exact? I do not have any calib_dist.exe or calib_cparam.exe. Where can I download?

Do I even have to change some C++ lines or xml or whatever.
Of course, I can change camera yaw and pitch a little to compensate this shift in bluprint, but I would like to do a more proper calibration.

Thanks, Peter
