Hello,
I am using Unity 5.4.3f1 and Vuforia 6-1-17.I am witnessing a strange disadvantage in my app.The single most 3D object which is the key element in the AR project is shaking now and then.I have took all the precautions to avoid the shaking, but no use!
The screen orientation s very basic - 1).ARCamera,2).ImageTarget,3).3D child.In this video the shaking is very small at the rear portion.But sometimes The object completely tilts and turn upside down,and sometimes it rotates for a random z angle and floating far off to the image target.
I have checked extended tracking checkbox in on state.removed unneccosory code components like smartterrain related code on ARCamera as smartterrain is deprecated and also not active in this scene.How could we deliver such uncontrolable apps to clients?Except following all the guidelines laid by vuforia I am not doing any erroneous things.Vuforia has to guide me how to control this unwanted shaking/tilting/floating.
P.S:This 3D object is very small,I am working on same lines in another project.There it is a large 3D object and shaking also too much.That project is going to be shelved out soon and this was started as a remedy.So, Please find me a way out.

Looks like your image target
Looks like your image target is too simple, it probably needs more feature points. Look at the yellow feature dots in the target uploader and you'll see it only tracks corners, your target has a lot of curves which will be ignored.
Thanks for responding.This
Thanks for responding.This marker is having 4 stars in the admin marker upload screen.But whata bout the second marker which I am showing in the video along this question.This is the key project .This marker also got 4 stars in trackability estimation screen.One thing I sudenly want to tell you n
Your target is not laying
Your target is not laying perfectly flat and the paper looks folded and crumpled. I don't know the exact reason for the jitter, but start with the basics, and get a perfectly printed target sorted out first, then you can move on to find out the real issue.
I am very happy for the
I am very happy for the response.Yes,the marker print is now dirty as I am using it for so long.But,the shaking which you have observed is the real problem and it is like that from the first hour from which moment I started to use that marker as fresh print
Like I said, share your
Like I said, share your marker image if you'd like me to test. From the video it appears you could probably get stable tracking from it and there's something wrong with what you are doing.
OK,I am following your
OK,I am following your suggestions one by one:
1).share your marker image if you'd like me to test:-I am attaching the marker image.It is decorated wit a gradient b blue clouds and metallic body ,but I am using B/W print.
I don't think this is an
I don't think this is an issue with Vuforia and it's something you could be doing better. My quick test seemed pretty solid: https://www.dropbox.com/s/mbi4l25sqz76zlw/EOCB7965.MP4?dl=0
Some things to try:
I took all the care to stop
I took all the care to stop this jitter fully.Even after considering distance and Camera angle and hand movement factors little jitter is still there - Can't I make a 100% jitter free AR app?I have did the same experiment placing simple 3D cube as child to Marker Image Target earlier.It is workin
