Detection of stair steps

Python-based 3D geometry pipeline for measuring raw .obj mesh objects using oriented bounding boxes (OBB). It extracts vertex data, applies PCA to find the object’s natural orientation, computes tight bounding box dimensions and volume, and validates results via Open3D-based 3D visualization, similar to real-world 3D scanning, measurement systems.

A mobile app that uses computer vision to scan and measure physical items and storage spaces, then calculates and visualizes the optimal arrangement for efficient organization in limited spaces.
