Generating 3D roof meshes from aerial LIDAR data

January 2, 2018

This is my graduation project I did in computer science. The goal was to come up with a method to generate 3D meshes of building roofs from point cloud data. The point cloud data was taken with aerial LIDAR scanners and is available online. In addition, I used building layout polygons, which are also available as open data. I tested several strategies to generate a mesh and I’ll explain the best one in this post.

Computer Vision and Robotics Demo with Raspberry Pi

July 2, 2016

This spring, I spent some time at SAP’s commercial hackerspace. I wanted to explore how computer vision can be used with embedded devices and robotics. I built a demo that can detect QR codes and similar symbols and point a laser at them. Possible applications of this are putting QR codes on objects to help the robot locate them and grab or manipulate objects. Another possible use case is local navigation. A robot could infer its own location and orientation in space by detecting QR codes with known locations.
