I’m building a low-cost handheld intraoral 3D scanner and I’m now focused on a single milestone: extracting key measurements from the captured images. Using OpenCV on the Raspberry Pi image set, I need a lightweight script or module that automatically calculates the distance between adjacent teeth (inter-tooth spacing). Scope of this milestone • Take multi angle images from a dataset available online freely and share that dataset with me. • Detect dental contours reliably in varying lighting • Compute accurate inter-tooth distances and output the values in millimetres • Return well-commented Python code and a brief usage note so I can integrate it into the larger pipeline later Keep the solution lean—no extra UI, just a clear, reproducible routine that demonstrates the measurement accuracy.
