Photogrammetry is the science and technique of measuring things with photos. The photogrammetric procedure is intended to extract precise data from aerial photos.
Photogrammetry is a technique for recording complex 2D and 3D motion fields. It imitates the stereoscopy of binocular human vision and is used to obtain all of the information about existent physical objects.
Indeed, this procedure captures information on the shape, volume, and depth of the topic you're attempting to scan. This is the process used to convert a series of images into an exact 3D design.
Meshroom
COLMAP
Colmap is a Structure-from-Motion (SfM) and Multi-View Stereo (MVS) pipeline that can be used for a variety of purposes. It can be used with either a graphical user interface or a command-line interface. You can select the one that is most convenient for you. You will have access to all of the basic tools required to generate a 3D model from one or more images.
MicMac
MicMac is open-source photogrammetry software created by the IGN (French National Geographic Institute) and the ENSG (French national school for geographic sciences). Even though it is a free option, MicMac is better suited to advanced or academic users. This software is excellent for environmental projects, cultural heritage imaging and preservation, and forestry. MicMac can handle everything from close-up to aerial shots.
Multi-View Environment
The Multi-View Environment, or MVE, is a full end-to-end pipeline for image-based geometry reconstruction. Structure-from-Motion, Multi-View Stereo, and Surface Reconstruction are all included. Individual pipeline phases are provided as command line apps, however the majority of functionality are also available through our user interface UMVE. Michael Goesele's research group at TU-Darmstadt is working on the project.
Reality Capture
3DF Zephyr
This software allows you to use photos to recreate a 3D digital representation. Everything is automatic, and you don't have to intervene because of its efficient reconstruction technology. As we saw in the last part, there is a simple and free version of this software. However, according to on your demands and project, you will be able to choose between three versions of 3DF Zephyr: Lite, Pro, and Aerial. These advanced editions enable you to go further, such as obtaining laser-scanned objects or working more precisely with aerial pictures.
Autodesk ReCap
Autodesk created a free software called 123D Catch a few years ago to assist with the conversion of a photograph into a 3D model. This software is no longer accessible, however, Autodesk still offers several interesting photogrammetry options. Autodesk ReCap (formerly Autodesk ReMake) is a reality capture software made by Autodesk that allows you to generate extremely precise 3D models by capturing reality.
Advanced photogrammetry capabilities, such as aerial photogrammetry, are available, as is the ability to measure and manipulate point cloud data. You can also use Autodesk ReCap to access a variety of tools, such as cleaning off extraneous items so you can work more directly on a certain object!
