Vuforia Model Target Not Getting Recognised.

[adityawadhwa05]

Objective:
I am building an AR application for android that provides a demo of the operation of a pipe bending machine. I am using Vuforia Model target for the same. (Project A)

Summarize the bug:
Vuforia Model Target Not Getting Recognised.

Observed problem
In the first testing, the model target got recognised only when 3D GuideView was enabled. After switching from 3D GuideView to No GuideView, the model target is not getting recognised. The problem could also be that the model target is getting recognised but not showing up on my device.

Expected result
The Model Target should get recognised and information should appear.

Vuforia Engine version:
v10.28.4

Unity Engine version:
v2022.3.54f1

My Approach to the Problem:
I made another project, Project B, with another machine as a model target. The model target is recognised in Project B successfully. The settings for the Project A and Project B are exactly the same.

Additional comments
What could be the potential solutions for this problem? Also, what are the parameters that vuforia uses to recognise a model target?

Hi, thank you for the report.

A good place to start is the Unity logs. It should tell you if the first Project A object gets detected. Other reasons why the object in Project A might is not detected include:

• lighting conditions are poor
• The Project A Model Target setup has a wrong scale or doesn't resemble the pipe bending machine; they look different. Is your Model Target from a CAD or 3D scan?
• The object has very few features and edges, making it more difficult for Vuforia Engine to detect. Which Tracking mode are you using? Default or Low Feature Mode?
• It can be more challenging to detect Standard Model Targets with no Guide View as a visual cue for the orientation and distance.

It's also helpful to consult the documentation on Model Targets best practices

Hope it helps,
