Structure From Motion
Structure from motion (SfM) is the process of estimating the 3-D structure of a scene from a set of 2-D images. SfM is used in many applications, such as 3-D scanning and augmented reality. SfM can be computed in many different ways. The way in which you approach the problem depends on different factors, such as the number and type of cameras used, and whether the images are ordered. If the images are taken with a single calibrated camera, then the 3-D structure and camera motion can only be recovered up to scale. up to scale means that you can rescale the structure and the magnitude of the camera motion and still maintain observations. For example, if you put a camera close to an object, you can see the same image as when you enlarge the object and move the camera far away .
Pix4Dmapper is the leading aerial photogrammetry software. It turns your images into highly precise, georeferenced 2D maps and 3D models. They’re customizable, timely, and complement a wide range of applications and software. Hyperceptions uses Pix4Dmapper extensively as well as other software to deliver high quality products.
