AR-Database for Object Detection

December 17, 2018 - 2:44am #2

Hello, everybody,

in addition to my question in the other thread, I need your advice once again. We have received a request from a company if it is possible to make their object database recognizable with AR. That means: In the company there are about 5,000 different objects for which the CAD data exist. Employees should now be able to scan and receive information about one of these objects when it is lying around, using a mobile device, preferably a tablet, regardless of whether it is iOS or Android. The general idea is "that simple", but the scope is problematic. As far as I understood it, it is not possible with Vuforia to store so many objects in a database for the AR-Camera, or am I wrong? If so, what would be your opinion for solutions to recognize the objects. They don't have to be tracked at first. Merely recognized + information are faded in.

Many thanks for your help

The 7.5 Vuforia Engine SDK implementation of Model Targets limits a single, 3D object per device database (aka dataset). Due to the size of the datasets generated by the Model Target Generator, we wanted to be careful to not be a memory hog and thus leave it up to app level logic when more than one device database is used (i.e. loading, unloading, activating and deactivating datasets). My guess is that this could be challenging to implement with UX for thousands of objects.

Our 8.0 SDK release will include a feature called Model Targets Advanced Recognition. This feature is able to handle multiple 3D objects to be recognized as Model Targets, using machine learning to recognize the object and guide view required for detection and tracking. I don't know if this will scale to 5,000 objects, but it may still be of interest to you to evaluate.

Stay tuned as we are currently on-track to release this mid-January 2019.
