Matrix and push-broom digital airborne sensors.There are many different options for capturing this stereo imagery. Stereo Imageryįirst, you need to capture the imagery of the area you are trying to map. What Tools Are Needed for Photogrammetric 3D Mapping?įrom start to finish, there are several tools you need to create a 3D map. With the proper hardware and display, and sometimes special glasses, you can create and see 3D maps.

Just like our eyes create depth by processing two different images, photogrammetry software creates 3D maps with images taken from two or more slightly varying viewpoints and combining them to create depth. How Does Photogrammetry Help with Creating 3D Maps? Want to jump ahead and learn more about Summit Evolution? Discover our world-class photogrammetric workstation. From this 3D environment, we can pull meaningful 3D data that provide vital information for a variety of industries, from government organizations to commercial agriculturists. This scientific process starts with a pair of 2D photographs, such as aerial photographs taken from a drone, and converts them into a 3D view using photogrammetric software, such as Summit Evolution.
Modern photogrammetry works using a very similar process to create 3D maps. Our brains take these slightly different images, process these variations, and match them to perceive depth. Since each eye is a couple of inches apart from the other, each sees an image that is different but very similar. How does this work exactly? After all, the world certainly appears as if it’s three-dimensional. This ability allows humans, and certain animal species, to perceive depth and judge distance. And while humans are only truly capable of seeing in 2D, everyone with two functional eyes has stereoscopic vision.
