Complex object with transparency

By danilandau on Thu, 06/08/2017 - 17:10

I have two related questions -

Image removed.

 

1. I am trying to use a metal grill / bars as my target. The aim is to make video with alpha appear behind the bars.

 

Is it possible to have an image target with transparency?

 

or to build an object target to do this.

 

If not is there another environment that would be better to do this in other than Unity / Vufioria

 

2. The target recognition is working very well with an image of the target, but not very well at the actual place. 

In contrast aurasma is picking up the target at the actual location. I would prefer to remain inside Unity Vuforia.

 

Is it possible to alter parameters to increase the the lightly hood of object recognition?

 

Many thanks in advance, Dani, Bristol, UK

Hello,

Our tracker is resilient to partial occlusions, but our detector is likely not.

Very difficult for me to ascertain why you'd be having mixed results. However, I'm assuming environmental differences may be coming into play with respect to lighting, distances, etc.

Hello, just a quick follow up question to the forum - would you recommend smart terrain or extended tracking in this case? 

Could Smart Terrain be used to do the occlusion masking or could extended tracking be used with the floor in front of the bars as the tracking plane? 

Hello,

Note that both Smart Terrain and Extended Tracking require an intialization target to bootstrap plane finding/tracking.
