Search Results for "photogrammetry"

Photogrammetry is the science of making measurements from photographs. It infers the geometry of a scene from a set of unordered photographies or videos. Photography is the projection of a 3D scene onto a 2D plane, losing depth information. The goal of photogrammetry is to reverse this process. The dense modeling of the scene is the result yielded by chaining two computer vision-based pipelines, “Structure-from-Motion” (SfM) and “Multi View Stereo” (MVS).

...With more than 1,000,000 downloads, CesiumJS powers apps that reach millions of users. We believe that collaboration is rooted in openness, and are committed to an open ecosystem. Stream, style, and interact with 3D buildings, photogrammetry, and point clouds using the 3D Tiles open specification.

...Its aim is to extract discontinuity sets from a rock mass. The input data is a 3D point cloud, which can be acquired by means of a 3D laser scanner (LiDAR or TLS), digital photogrammetry techniques (such as SfM) or synthetic data. It applies a proposed methodology to semi-automatically identify points members of an unorganised 3D point cloud that are arranged in 3D space by planes.

...You can fly around your favorite outcrops and see unique angles that are impossible or difficult to get in real life. With the laser pointer tool, you can create lines and planes that then display the trend/plunge or strike/dip. Use the Unity menu to select Tools/Localize Photogrammetry Model from UTM. This function takes in a photogrammetry .obj file that is in UTM coordinates and converts it into smaller numbers so that Unity can work with it. If a texture file is supplied as well, it will be mapped onto the object.

The objective of the project is to automate the generation of 3 dimensional coordinate points from a set of 2D images. The entire project is based on the principles of Photogrammetry. The subject of interest is embedded with patterns of retro-reflective dots. The reason that these dots were attached is that they appear very bright in the image if it is captured using flash. An auto-bar is used to define the coordinate system reference. The algorithm which performs this transformation is broken down to several steps. ...

Sterobil is a project used to build a 3D model from photographic pictures, based on the principle of photogrammetry. This project was developped by ECE students, in collaboration with the C2RMF.
