The best photogrammetry software can automatically generate 3D models from photos. Photogrammetry uses the parallax obtained between several overlapping images taken from different points of view. It works by extracting the geometric information of a 2D image, such as the shape, volume and depth of an object. Photogrammetry software can then align, texture and mesh multiple pictures to create a 3D model. It allows you to capture large objects, such as buildings and landscapes, that would be impossible to scan any other way.
In aerial photogrammetry — or drone photogrammetry — the camera is mounted on an aircraft or done and is usually pointed vertically at the ground, with multiple overlapping photos taken as the aircraft or drone moves along a flight path. Terrestrial photogrammetry, also known as close-range photogrammetry, is where the camera is located on the ground and either handheld or mounted on a tripod or pole.
Whereas aerial photogrammetry is often used for topographic products like maps and terrain models, terrestrial photogrammetry is used for non-topographic products like drawings and 3D models. For example, some software can be downloaded free and are ideal for beginners, while other paid software packages are much more advanced and used in professional settings. Similarly, different software solutions are better suited to different applications, whether that be architecture , construction, object scanning, or other applications.
In this article, we profile the best photogrammetry software available today. It converts photographs into accurate 3D models that you can use in your project. The software can be used for both aerial and terrestrial photogrammetry. ReCap can also process laser scans and is widely considered one of the best software for point cloud work.
It quickly and easily simplifies all scans into a number of point clouds, and there are a variety of settings that can be applied before the project is indexed and finalized into the unified point cloud. ReCap has numerous high-quality analytical tools, advanced editing tools and collaborative tools. You can measure and edit cloud point data, and you can easily output a point cloud or mesh to use with other CAD software.
There is also a free trial that comes with 24 cloud credits. Formerly known as Agisoft Photoscan, Agisoft Metashape is a professional photogrammetry software often used for Geographic Information System applications, game development, cultural heritage documentation, visual effects, and indirect measurements of objects of various scales.
Metashape can be used to process both aerial and close-range images and includes some great tools for editing the point cloud before generating a 3D mesh which can then be exported to various formats. Hunsaker has also provided tutorial videos on his website, which successfully got my students up and running quickly. I can create basic geometries and get basic analyses in a few minutes. I can quickly go through a dozen or more configurations and compare them all with each other.
The ease of creating and analyzing geometries is great for the conceptual and creative part of the aircraft design process. And I can take screenshots to show people what designs look like in general terms instead of using 3-D modeling software like SolidWorks, which is more time-consuming.
While there he used MachUp to design an aircraft called BluJay, an aerial platform that weighed about 25 lbs. As director of flight testing and aircraft development at Vayu, Inc. He hopes to use MachUp at his new job at Teal. All in all, Hunsaker hopes that drones have a bright future in front of them, in part due to MachUp.
