SLAM SCAN of A STAIRWELL

Overview

This project involves capturing drone imagery of a small building to generate a textured 3D mesh using photogrammetry. Output is intended for visualization and presentation purposes only.

Objectives

• Plan and fly a drone mission around a structure to capture overlapping oblique imagery

• Process images in WebODM to generate a dense point cloud, mesh, and textured 3D model

• Export and view the model in 3D viewers or GIS software for further analysis

• Assess model quality and geometry for improvements in future captures

Tools & Methods

• DJI Mavic Series

• WebODM (3D reconstruction and mesh processing)

• p3d.in for model hosting

• CloudCompare for point cloud clean up

• Cesium ion for visualization of point cloud

Results

• 3D textured mesh file (OBJ or GLTF)

• Point Cloud (LAS or LAZ)

• Model video links

• Flight plan and capture settings documentation
