Object Target Best Practices?

December 8, 2016 - 4:09pm #1

So I've read through the Object Recognition docs and I just had a few questions. I've 3D printed a model, tried scanning it in various setups, lightings, tried to mimic the perfect lighting scenarios as described, but tracking is very poor. I know that Vuforia's tracking is top notch so I must be doing something wrong. 

1. My model is about 2 inches x 2 inches x 2 inches. Is this too small? Need it be larger?

2. Because I've 3D printed my model, it's all one color. The docs say "The surface of the object should have contrast-based features.' Does this mean I should paint the figure for best results? Or will this not improve tracking?


Thank you so much for your time! I appreciate it

I don't think that your model is too small, but if it is all the same color then my guess is that not enough keypoints were extracted during the scanning process. I agree with your assessment about adding contrast-based features to the object's surface.

To confirm that additional keypoints were added, you can compare the number extracted during scanning from the app.

Hope this helps.
