Combining Image Target with Scanning Object

September 6, 2018 - 9:11pm #1


I'm trying to combine two different targets (Image Target and 3D Scan) in my Unity application. Basically, I want the 3D scan target to augment a circuit board and breadboard, and the image target to track a complementary component (e.g. photoresistor) as the user places it over the breadboard. The idea of the application is to guide the user into placing a few components in the correct position on the breadboard. I can get each target to augment their parts individually, but the problem comes when I try to position the image target over the object target. The breadboard/circuit augmentation board often starts to jitter and rotate, losing its position drastically. I imagine this is due to the image target blocking the view of the breadboard, so the AR camera loses it's tracking of the breadboard? Is there any way I can keep the object target's position even when it's obscured slightly by my image target? Any other recommendations? Any help on this issue would be great.

Thanks for your reply. 

I enabled Device Tracker, set tracking mode to POSITIONAL and set fusion mode to "Optimize for Image Targets and VuMarks. I think this helps but occasionally, the circuit board and breadboard models turn 90 degrees to one side.

Hello ICTProjectUser,

Have you tried enabling the Device Tracker for this? The Device Tracker will allow for extended tracking to take place and will be able to keep the position of your object even if it is obscured a bit by your Image Target. Our Core Samples have examples on how to activate and utilize the Device Tracker.
