The objective of this project is to create an accurate 3D model of the baseball stadium, focusing on “Press box”, home plate and extending out to first base and third base. All physical obstructions that are within the azimuth of the Doppler radar field of view were identified using the model. The Doppler radar tracks the baseball velocity, trajectory, ball spin and other factors. Any nets, cables, poles may interfere with the radar and would need to be taken into account for the design or upgrade.Read more
“Datumate’s advanced photogrammetry software, enabled us to get quick and very accurate results, as required by our customer. Its unique capability of working directly on actual digitized images enables easy identification of small and thin objects for faster completion of work.”
Mearon Okonsky, Hummingbird Systems
DJI Phantom 4 PRO was used for quick, precise and easy image capturing. Best results are achieved with DatuFly™ app for drones, using oblique flight pattern at 40m (131ft) altitude and radius. It takes only 6 minutes to get all the required images to achieve, better than 2cm (0.065 ft) resolution.
Working directly on the actual digitized images, allows DatuSurvey™ Photogrammetry solution users to identify and extract every object, even as thin as a cable. In other photogrammetry solutions, users must work on point cloud instead of digitized images, making it practically impossible to see thin objects such as cables.
Figure 2: The Focus Area
The Drone’s imagery was analyzed and processed using DatuSurvey™ Enterprise photogrammetry software to quickly generate a dense point cloud and true Orthophoto images, identify and measure objects, as thin as cables, and draw directly on the images.
A point file, including names, codes and coordinates of all new points was generated. Overall, 70 new points were drafted directly on the images.
The measurement accuracy of all the points was better than 2.5 cm (0.08ft) in 3D coordinates.
True orthophoto was generated from the vertical flight.
Texturized Dense Point Cloud
A 3D CAD model in DXF format was created. It included the area topography, concrete structures and additional objects that were generated by drafting directly on the images using DatuSurvey™ Enterprise.
