  In general, photogrammetryis the science of obtaining reliable data about physical objects through the process of recording, measuring and interpreting photographic images. Photogrammetry is often used by surveyors, architects or even engineers to create topographic maps, meshes, points of clouds or drawings based on the real world. In the field of 3D printing, photogrammetry becomes handy because it can replace 3D scanning, the latter being the usual technique to collect data on the piece you are trying to model. Basic Concept Of Photogrammetry:-

  Autodesk ReCap softwareconverts photographs into a 3D model or 2D drawing that is ready to be used in your project. In fact ReCap stands for Reality Capture, meaning that the software works either by aerial photogrammetry, which means using aircrafts to produce aerial photographs that can be turned into a 3D model or mapped digitally, or using close-range photogrammetry, where images that have been taken using a handheld or tripod-mounted camera are then used to make 3D models of smaller objects.

  Agisoft Metashape:- Agisoft Metashapeis a professional software that performs photogrammetric processing of digital images for various applications, such as Geographic Information System applications, cultural heritage documentation, visual effects, production, as well as for indirect measurements of objects of various scales. Some important features enable Metashape to process various types of imagery (whether aerial or close-range), output a point-cloud, measure distances, areas and volumes, and generate 3D meshes that can then be exported to various popular formats. It is also possible to edit 4D models, which means entire scenes can be recorded in 3D and then manipulated on the software.

  AliceVision Meshroom:- Meshroom byAliceVision is a free and open-source 3D reconstruction software that uses photographs to create the textured mesh that will become the structural build of your 3D model. AliceVision is a photogrammetric computer vision framework that relies on a community of people that invest in the creation of open-source software such as Meshroom.

  Pix4D:- Pix4D is abeginning-to-end photogrammetry solution, on top of being a software it also assists in the capture of suitable images. Pix4D has developed mobile apps for Android and iOS that turn consumer drones into professional mapping tools. Pix4Dmapper is the photogrammetry software for professional drone mapping, then additional features include Pix4Dcapture to get optimized images, Pix4Dbim for earthworks, construction and infrastructure management, etc. Pix4Dmapper generates point clouds, orthomosaics, elevation models and more.

  PhotoModeler Technologies:- More likelyto be suited for CAD or CNC manufacturing than some of the other photogrammetry software solutions on the market, PhotoModeler offers exact measurements and models from photographs taken with an ordinary camera, just like the one you have on your smartphone. This is a cost-effective solution for accurate 2D or 3D measurement, as well as surveying, digitizing, reality capture and more. Inside PhotoModeler, you can choose three different methods to generate the model you are trying to recreate. You can manually match common features between images, automatically generate a 3D model from coded targets, or generate point clouds from overlapping images.

  RealityCapture:- CapturingReality created theRealityCapture photogrammetry software that works with a wide variety of input media. RealityCapture enables you to create virtual reality scenes, textured 3D meshes, orthographic projections, geo-referenced maps and much more from images. It is also possible to work with laser scans on this software, if you are looking for both options. The user interface is clean and modern, as well as intuitive for people who haven’t used this software before.

  Regard3D:- Regard3D is anotherfree, open-source software solution, they call it a ‘structure-from-motion’ program, meaning that it can convert photos of an object taken from different angles into a 3D model of this object. You can run this solution on a multiple platforms, Windows, OS X and Linux and count on powerful third-party tools and libraries.

  Trimble Inpho:- Trimble Inphois one of the leading software solutions for digital photogrammetry, offered by Trimble Geospatial. Again, this software is aimed at aerial images; it transforms them into accurate point clouds, surface models, ortophoto mosaics and digitized 3D features. This is a reliable solution as it is one of the oldest on the market, with 30 years of experience, Trimble Geospatial is capable of offering a robust solution.

  WebODM:- WebODM is asolution designed to be user-friendly and produce elevation models, textured models, geo- referenced maps and point clouds using aerial images from drones. This software is a project from OpenDroneMap, which is an open ecosystem of solutions for collecting, processing, analyzing and displaying aerial data. Once you download this drone photogrammetry program, it runs on your computer even when offline.

  3DF Zephyr:- 3DF Zephyris a software solution by 3DFlow, it deals with the automatic 3D reconstruction of an object no matter what sensor, drone or laser scanner device you are using. In other words, with this professional photogrammetry software, while it generates 3D scans with ease, experienced users can make extensive alterations to optimize the result. A user can also export the model into many file formats.

  Photogrammetry in away is the same as 3D scanning an object you wish to collect data on. It is just another way of collecting data on this object, through the use of a photograph instead of laser triangulation technology in the case of a laser scanner for example. Then, the photogrammetry software works by using this data to reconstruct a model, starting with point clouds that are transformed into 3D mesh. In order to be accurate the consecutive images you take of an object or structure need to overlap by 80- 90%. There are currently many options on the market, and above we gave you a general overlook of what you can find, with hopefully a solution for everyone. If you are looking for a free and open-source option you can also have a look at photogrammetry software such as COLMAP, MicMac, VisualSFM and OpenMVG. Another solution for drone photogrammetry is Hexagon Geospatial or IMAGINE Photogrammetry. Conclusion:-
