Walking Around/Through Big Objects!

May 12, 2017 - 3:18pm #1

Hi guys, 

When I walk around the model or through it I see there is like 1 to 2 inches off in Y, X axes. If I look/get back to where I placed the marker the object is perfectly overlaid on the physical object. if I walk or move, I start to see some X or Y off. The distance between the marker and the model is like 15ft. Is there any solution to better overlay the model contant exactlly while I walk or move around that model? 

All I am doing is to augment big objects over physical ones. They are identical. So it is easy to figure out if there is any offset issue. Is there another process (ex: to incorporate two markers) to prevent the X Y offsets while we move or walk around the models? 


I used Vuforia HoloLens sample 6.2.10. Unity 5.4.  



Thank you

For see-through experiences, perfect registration at all distances is difficult to achieve. This is because your inter-pupil distance (IPD) changes depending upon the focus of your gaze. This is why you don't see many eyewear demos where exact augmentation to physical object registration is required.. Although HoloLens has good calibration, I've still seen this manifest itself primarily in scaling (Z offset).

I'm not aware of any workarounds on HoloLens to insure exact registration at any distance. From the demos that I've seen, this would require real-time IPD measurements using an eye tracker.
