Detecting Small Objects using Vuforia?

December 2, 2020 - 7:47am #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 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.


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 or would it not even be able to detect it in the first place?
