Material used for input

November 13, 2018 - 6:49am #1

In the Model Targets best practices guide it is stated that "you can use a model target for multiple different colored versions of an object" does this mean the material linked to it in Unity is used to determine the color of the product to look for? Because it also says adding a material greatly improves recognition during runtime.

 

With kind regards

Hello,

Thanks for the link. I better understand the statement now.

What it's saying is that the object you're trying to detect does not have to be colored exactly the same as the 3D object loaded into the Model Target Generator. Basically, the color information from the 3D model is used to extract geometric features for better detection and tracking robustness, but the color information itself (e.g. blue, red, green, etc) is not used.

Thus, if two of the same objects had different paint schemes, Model Targets detection and tracking would be agnostic to the difference. It should detect and track them the same.

Thanks,

Can you send me a link to the exact article where this statement can be found? I was unable to locate it.

3D model colors and materials are used during Model Targets dataset authoring, using the Model Target Generator, to introduce additional geometry for improved object detection and tracking.

I'm not aware of our product being able to differentiate colors during run time.
