A major sporting organization reached out to Flight Evolved for help kicking off a challenging data verification project for their broadcast analytics. Flight Evolved deployed LiDAR teams to each event stadium across the United States to capture highly-detailed and highly-accurate 3D point clouds, oriented to suit their internal coordinate systems.
The first challenge with this project was to determine the most effective technology to use for data capture. Our client was interested in using aerial technology to acquire data However, it quickly became clear that aerial systems would not generate the density needed to accurately map the stadium. Our team generated a new workflow that leveraged terrestrial scanners to capture highly dense (thousands of points per meter) point clouds of each stadium.
Unique Coordinate Systems
In order to deliver the data, we had to orient the data so that our client could easily reference it within their existing X-Y-Z coordinate system. We couldn’t use conventional survey methodologies because this particular coordinate system was not based on a conventional State Plane or global system. That’s why our technical team developed a geometric transformation to translate the RAW data into a 0-0-0 coordinate system that the league was able to easily implement.
League-Wide Development
The last hurdle to overcome was disseminating 3D data throughout various stakeholders across the league for review and approval. LiDAR is a new technology for the league, so we found that they didn’t know how to manipulate, view, and share the data internally. Our team developed a unique viewer using Potree so the league could access and view the data on their existing internal intraweb. This meant that the data could be easily shared across the league and anyone with a web browser could open, view, and manipulate the data.
