Photogrammetry

Aerobotika’s advanced aerial photogrammetry systems collect valuable information about land and structures to provide you with the data and photo overview that you need to make smarter decisions about your property, resources, and structures.

What is photogrammetry?

Photogrammetry is the art and science of obtaining reliable information from noncontact imaging about the Earth and its environment, and other physical objects and is the processes through recording, measuring, analyzing and representation. The simplest way to look at it is that the distance between two points that lie on a plane parallel to the photographic image plane can be determined by measuring their distance on the image, if the scale (s) of the image is known. This is done by multiplying the measured distance by 1/s. Now take multiple images in a grid and you are able to accurately determine dimensions. photogrammetry_01 Aerial photogrammetry as Aerobotika provides it, is a modern software driven photogrammetry service that uses our aircraft fleet to collect photographs from the air and bleeding edge software to create 3D models of the area surveyed. Aerobotika uses combination of extremely precise GPS coordinates, a grid flying autopilot, and high resolution cameras to produce the data that its customers need. How accurate is it? Like with many things, the answer is “It depends”. There are many factors when collecting this kind of data and we can provide data varying in accuracy from 7 CM per pixel down to 3 CM per pixel. We can also fly lower and slower to take more pictures and have more points of reference to produce more accurate 3D. What does it look like? This is a photo overview of the area. Here we have stitched together all of the data to provide a simple photo of the entire area. This is a 3D model of the area studied. Here we have crunched all of the photos to come up with the 3D model, stripped the photo data, and represented it in 3 dimensions with shadows to show the dimensions in detail. In this model we have added elevation information to the 3D model. We can also display elevation lines without the shadows. photogrammetry_04 And finally, this is a full 3 dimensional model rotated to a different perspective and with the photographic information overlaid.
