I am working with Unity 2017.4, Vuforia and the Hololens.
I have to align a virtual model with the physical equivalent of it. One method to do this is with a Vuforia ImageTarget. The model is ~1m big. In the middle, where i place the ImageTarget, it works very well but at the edges of the model the deviation is getting too big.
Is it possible to use multiple images for one model? As in one image on the left edge as an anchor point and one image on the right as an anchor point.
I don't have any code to show since this is a question about the concept.

A Vuforia model-target allows you to align 3D virtual models to a matching physical 3D model.

Yes, this is possible using Multi-targets. There are examples for cubes, but you can configure multi-targets for any regular shape made of flat planes.
What I need are 3-4 Target points on the edges of a plane
Multi-targets can include coplanar image-targets, and can give better performance than four individually tracked image-targets averaged together. However, the most reliable approach is to have one large image target which covers the entire area.
