What is very important in photogrammetry is that the algorithms that are used here are trying to minimize the sum of the squares of errors. Through photogrammetry we can track all changes that occur on earth, including the direction of flight of birds, the movement of fish from the sea, and other movement processes. Mapping with drones is very similar to this, the main difference being the low altitude a drone can fly and capture higher quality images. With photogrammetry you can capture 2D and 3D fields with high-speed imaging. If you didn’t know more than 90% of today maps that we use were made using photogrammetry and we use that maps today. When we talk about photogrammetry, its input is photography, and its end point is a map or some kind of 3D model of an object. Photogrammetry can be defined as the science that is measured from photographs, usually those taken from the air. Meaning of Point Cloud in Drone Mapping. So let’s explain some basic things you need to know about drone mapping. A lot of people become FAA-certified remote pilots, flying UAVs and providing mapping services. Another thing you need to know is that the FAA and federal law require the UAV pilot to be certified. In the last couple of years since FAA passed the law and allowed the use of UAVs, many people turned on to provide these mapping services. One of the purpose of using drone mapping is way of providing mapping services to clients. If you’re professional you can make it so useful for things like surveying property, checking on your crops if you’re a farmer, or simply charge the service to someone that need a 3D map. But what exactly is drone mapping? Simply put, Drone Mapping is when you specify the area that you like to map and the drone flies around that area and makes a 3D map out of it, and this technique is called Photogrammetry. And one of these applications which is very profitable is Drone Mapping. UAVs are now used in a large range of commercial applications, whether it’s television filming, real estates, package delivery, weddings or 3D mapping. The drone industry is growing at an incredible pace and the technology provided by the drones is limitless.
