Deviations Across Scans

Post by kate_Jelaine »

Hello,

I am taking scans of a replica shin bone with soft-tissue meniscus. The bone does not change from scan to scan. I have produced two different models. All scans were taken right after each other (i.e. all 8 scans taken for model #1 then all 8 scans taken for model #2. Object was not moved between scans).

I am seeing large deviations in the bone models. I am trying to preform boolean subtraction between the two models to isolate the soft-tissue on top. However, I am not able to get perfect subtraction between the two models because of the deviations.

Does anyone have tips for how to generate less deviations between models?

Thanks!
Kate

I am using an HDI Advance R2 projector with cameras from LMI Technologies. The scanning software used is FlexScan3D v 3.3.5. My scanner set up is shown in the accompanying picture.
