Although 3D mapping has been done for years using various methods, UAVs now offer a new economical alternative to conventional methods. This first image is a mosaic created from a fly-over with a UAV operated by Story In Focus.
It is constructed of 28 images shot from 162 feet above the take-off point. While the autopilot triggers the camera, it also records the GPS position of the UAV. All the position information and photos are imported into the photo analysis software. Through the miracle of mathematics and image recognition, the software creates a point cloud in 3D space that represents the terrain.
This point cloud contains all the information needed to create a 3D surface model of the area. The texture mapping is completed next, giving the surface a realistic appearance.
There are many benefits to having a 3D surface model with texture mapping and software capable of analyzing the information. Do you see the light colored gravel pile in the foreground? That gravel pile contains 596 cubic meters of material. How do we know that? Well, we used the aerial survey gathered with our UAV and Agisoft software (www.agisoft.com) to calculate that information. This complete aerial survey and results were obtained within four hours from the take-off of the UAV. Models created by the software can also be imported into other mapping and design software for use by engineers, architects, aggregate companies, landscapers, and others.
Not only do UAVs produce wonderful aerial images and videos, they also can provide valuable information at a lower cost than conventional methods. This example is just one of the possibilities. Together let’s find ways for your company to reduce costs through the use of our services.
