'ALIGNING an AR view of a room with the ACTUAL view'

By maksdesk on Sun, 10/18/2015 - 03:06

Hi,

It has been 3 weeks [including 2 all-nighters] that I have been working on this project on a mini-iPad:

'ALIGNING an AR view of a room with the ACTUAL view'

[as seen via the device camera view in vuforia]

I have tried creating huge markers [1m height] and placing them a short distance apart [multi-marker setup], so that I can get the AR view to align as closely as possible to the actual view, but there is a variance between the farthest points in the AR view and the actual room view.

I have looked at a number of discussions in the developer portal.

Some of the discussions which are closest to what I am looking for are:

https://developer.vuforia.com/forum/unity-3-extension-technical-discussion/ar-camera-field-view

https://developer.vuforia.com/forum/unity-3-extension-technical-discussion/vertical-fov-unity

http://docs.unity3d.com/ScriptReference/Camera-projectionMatrix.html

http://kwazylabs.com/blog/unity_sync_ar_camera_with_2nd_camera/

https://en.wikibooks.org/wiki/Cg_Programming/Unity/Projection_for_Virtual_Reality

I can keep trying all the ideas suggested in the discussions but I am lossing time and there is immense pressure on me to complete my PhD research ASAP [already 3.5 yrs have passed].

I shall therefore be most grateful if someone could kindly commit some of their spare time with me so that I can get through this challenge in the optimum way and in an optimum timeframe.

here are the results of using a multi-target configuration with extended tracking turned ON:

 - i was trying to check/understand the programmed behaviour of the client if it detects two markers in a multi-marker setup

this is the subject i am essentially dealing with: http://www.vision.caltech.edu/bouguetj/calib_doc/htmls/parameters.html

i am basically trying to find a way to align the AR view perspective projection exactly with the camera view perspective projection....

i wonder if anyone can tell if the below patch is implementable, or is it a hoax?

doesn't look like a hoax but i can't really figure out how to implement it....

e.g. does Ui camera mean the device camera? if so, then whre in the code can we implement this sync?
