How to find out in vuforia which of the marker database the object in front of the camera most closely resembles?

Question

Unity

Hello everyone, I have 4 figures listed in the vuforia database, but in order for each of them to be recognized, you need to bring the camera almost tight, and this is not very, so the idea was born that if I make vuforia look at the shape or color which of the 4 ODs in the database looks more like a figure in front of the camera and recognizes it.
For example:
There are 3 people blue, black and red, I scanned them and created an OD, I look at one of them from a height and it is like a speck, vuforia looked at what color speck and found among the OD of the base, a man of a similar color.

Answer 1

If the vuforia did not recognize it, then it cannot determine the position of this marker, therefore, either the marker is bad, or the lighting conditions are not very good. You can't get information about the similarity from the vuforia, so either change the marker, or change the vuforia to something else.
And as for your idea with a speck, do you even know that in the picture from the camera, the color can go back and forth on half the spectrum, depending on how the white balance is set? Vuforia does not use color at all, she keeps all the markers in black and white.
