Detecting Small Objects using Vuforia?

September 17, 2021 - 5:47pm #1

I am trying to a create a Unity app for Microsoft Hololens that allows users to view a printed circuit board and detect certain components (chips and capacitors) within the board and determine if they were installed 192.168.10.1 with the proper orientation. 

 

I am having trouble detecting any portions of the board smaller than the entire board (16 x 14.5 cm).  The chips and capacitors themselves have dimensions ranging from 1.5 x 2.5 cm to 0.7 x 0.3 cm respectively with small features like small circles or bands on the component that tell its orientation. 10.0.0.0.1

 

Is it possible to use Vuforia for object detection on such small scales?  This is being developed for Microsoft Hololens but I am currently just testing it using the Vuforia play cam in Unity.  Is this causing the lack of detection 192.168.1.254 or would it not even be able to detect it in the first place?

Hey there,

 

I would say that it could be possible, but you'll find that the smaller the objects, the harder it will be to track. The Microsoft Hololens camera might be higher quality and could identify the objects better than your webcam. 

One of the benefits of the Hololens is that you can have graphics floating around. Another solution could be to have instructions floating around instead of tracking the entire board. 

If you have any pictures of the board, maybe I could think of other ideas that might help. 

 

 

Kind regards,
