3D Object Recognition

July 11, 2013 - 1:58am #1

Hello there,

I wanna do some 3D-object tracking, and was traying to do so with Vuforia SDK.

I've found this topic: https://developer.vuforia.com/forum/creating-ar-trackables/3d-object-recognition-0 saying:

"Vuforia doesn't currently support tracking of non-planar 3D contours. like spheres or irregular surfaces."

I'd like to emphasize on the currently. This message was 18 month ago, is it still not currently supported?

 

Thanks.

Many thanks. It's clear to me now!

The Sesame Street demo utilizes both the texture and geometry of 3D objects. But the current public SDK doesn't incorporate that capability. You can use MultiTargets to track 3D objects composed of an arrangement of planes, like a box or hexagonal cylinder, but this approach is not effective w/ smooth contoured surfaces, like a tennis ball.

The basic problem that you encounter when attempting to utilize a 2D planar target for 3D tracking is that while the 3D object may be trackable from a fixed relative perspective, the perspective distortion that occurs as you change perspective ( i.e. move the object or camera ) will alter the image of the object so significantly that it is no longer recognizeable from its 2D target reference. You can observe this using our UDT sample - generate targets from some 3D objects and then move the camera around a bit.

Sorry if I'm being a little stubborn, but why wouldn't it work? What's the difference with the figures we saw in the video?

Many thanks.

i haven't tried it, but i highly doubt it. but if it's just a table tennis ball, you might want to try open cv instead. or maybe fast cv, but i have no experience with that.

best,

I'm not sure to understand your answer.

I'd like to follow a little tennis table ball, and get its position in real time. Will I be able to do this with Vuforia?

Thanks for your quick answer :)

well, i don't know if 3D-markerless is the right term, but that is the sesame street demo i was referring to in my earlier post. so yes, it is detecting the 3d objects or at least the textured clothes they wear and the planar target underneath. however i don't know if it's also detecting and tracking the contour line of the characters. hope this answers your question.

I saw this videos: https://www.youtube.com/watch?v=tELbTjMfLDA.

It seems to be 3D-Markerless, doesn't it? That video as about 16 month.

Thanks, I just really wanna know :)

Hi Stefann,

unfortunately at the moment I don't have any timeline or ETA info for possible features related to the area of 3D object recognition.

Hi,

I'm also very interested in 3d tracking and I have a number of cases where I could use it. Can you give us any hints on the progress or a planned release timeframe (like later this year or anytime soon)? It has been shown with the Sesame Street demo a while ago and 3D object detection is already mentioned in the SDK License Agreement (yes there are people reading it...). So while I know that from a demo to a final product it can be a very long process, it would be really nice to have some more information.

Best,

Stefan

Still not currently supported.
