Vuforia object recognition
Hey guys, is somebody working with the vuforia solution?
If so, does anybody now how the object recognition works?
Are there any tutorials or has somebody made any experiences with vuforia object recognition?
Appreciate any answer.
Thank you for your attention

I don't have a link to a demo of the Object Recognition specifically, but I have done some Vuforia projects and the SDK includes a sample project or two.
These links may be of some help to you:
Demo Video
Great video showing Vuforia integration with Unity and Vuforia running across a bunch of Windows devices. The HoloLens portion starts at 3:15. Totally worth watching the whole thing. (5:31)

Printable Target Images for HoloLens Samples
These images are used as tracking targets in the HoloLens samples included in the SDK. They must be printed at 247mm x 173mm (9.7" x 6.8") for models to align to them properly.

Hi @jbienzms,
thanks for your answer my friend. I already worked with the image targets and solved the solution with the object recognition. It works nearly the same way like image target. Another question if you dont mind: Is the hololens able to track or recognize real objects (e.g. a big milling machine) if so, how can i do that? Do i need the HTK??
Also how can i anchor holograms into the real environment? As an engineer in the making its hard for me to deal with everything which has to do with computer science. I also have some difficulties to use the HTK and the scripts correctly?
Do you have any idea?
I appreciate it
@VR_HSRW1 HoloLens doesn't currently do object recognition in that way. There is a module called Spatial Understanding that can be used to figure out things like open spaces that connect the floor to the ceiling, or places where people can sit. But it doesn't do object recognition. The closest (that I know) are the object recognition system you've discovered in Vuforia and leveraging things like the Azure Face Recognition and other Computer Vision APIs.
Hope that helps.

@jbienzms,
ok i understand. Did you work with vuforia? Do you know how to create more than one image target?
I'll check the face recognition and the computer visions APIs as soon as possible
Thank you
I believe the vuforia for hololens sample download already has the scene set up with two image targets, you can just copy the image target object as many times as you want, you just need to set up the marker data for those targets.
@Elspin, okay i'll check it out. Thank you a lot
Have a look at the Vuforia library How To Add Targets to a Device Database
and the Vuforia Image Target Guide
I have used this to produce new targets from a pictures in a book.
The //Build 2016 showed just how to do this and Unity GDC 2017 showed model car then positioned a picture via HoloLens Spectator View Professional of a AR Real car in 3D.
