The Top 10 Best Photogrammetry Software 2020 (4 are Free!)

The best photogrammetry software is a vital tool for architects, surveyors and engineers for creating topographic maps, meshes and points of clouds based on the real world. It’s also the easiest way to 3D scan without expensive kit, so photogrammetry software tools are used to scan small objects, and even other people’s faces for small models.

There are many different options out there, including free photogrammetry iPhone apps. But for genuinely high-quality projects, you need more professional photogrammetry software.

What is Photogrammetry?

Photogrammetry is the science of extracting 3D information, such as measurements, from photographs. The process begins with taking photographs and inputting them into photogrammetry software, with the output being a drawing, measurement, map or 3D model of a real-world object or scene. 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.

Photogrammetry is useful in the world of 3D printing as it’s a technique for 3D scanning. It allows you to capture large objects, such as buildings and landscapes, that would be impossible to scan any other way. Photogrammetry software is also often more accessible and affordable, as it can be as simple as inputting a photo from your smartphone’s camera into the software and then having a 3D reconstruction automatically generated.

Types of Photogrammetry

There are two main types of photogrammetry – aerial and terrestrial photogrammetry.

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.

Best Photogrammetry Software

There’s a wide range of photogrammetry software out there, but you need to carefully consider the merits of each to ensure you pick the right software for you. 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. We’ll take a look at the uses, price and experience level of each software to give you a better idea of which package is best suited to your needs.

Autodesk ReCap Pro – Best BIM Photogrammetry Software

Autodesk ReCap Pro, ReCap being an acronym for ‘reality capture’, is used for 3D reality capture via photogrammetry. 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. You can then easily export your point clouds to Autodesk’s CAD software Revit for further modeling work.

One of the best things about ReCap is that it’s one of the best photogrammetry software for improving building information modeling workflow (BIM) thanks to features such as multicore processors for faster scanning and high precision GPS technology for 3D photo reconstruction accuracy. BIM is an intelligent 3D model-based process design to improve efficiency and collaboration, so it’s a vital tool for professional architects and other professionals.

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.

This Autodesk photogrammetry software costs $62 per month, or $490 a year. There is also a free trial that comes with 24 cloud credits.

Agisoft Metashape – Professional Software with Machine Learning

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. These include automatic classifications of point clouds to customize geometry reconstruction and extensive measuring tools to measure distances, areas and volumes.

You can also use Metashape to edit 4D models, whereby scenes are recorded in 3D and then manipulated on the software.

Another benefit is that Metashape uses community-driven data to improve its algorithms. This means that the software should improve the more its used, making for faster processing time and better quality of captures.

The Professional Edition will set you back $3,499, but there’s also a stripped-down Standard Edition available for $179, which is a better option for beginners.

In addition to the desktop software, Agisoft Cloud is currently available for beta testing if you own a Professional license or if you’re using the 30 free trial. This is an improved cloud processing interface that allows saving on the hardware infrastructure for a photogrammetric pipeline with more options to visualize processing results online.

Meshroom – Best Free Photogrammetry Software

You don’t need to break the bank to use quality photogrammetry software. Meshroom is free, open-source 3D reconstruction software developed by AliceVision, a photogrammetric computer vision framework.

Meshroom is based on a node-based workflow and uses photographs to produce the text mesh structural build of your 3D model. You can put your images in and the software generates 3D models and textured mesh, so it’s a very simple software to use.

The easy-to-use workflow connects all steps to generate a model, so you can simply push one button instead of having to activate each node individually, as you do in some other programs. Each node can also be work on individually, so the parameters are customizable and you can make tweaks to get the perfect result.

One of the best things about this free photogrammetry software is that you can view your 3D photogrammetry model in real-time as you make edits and add images to the dataset, so that you can see how additional data fills in incomplete portions of the model over time.

Meshroom is very user-friendly and has a more intuitive interface than many other photogrammetry software, so it’s a good choice for beginners. Meshroom is also available as a free plugin for the 3D modeling software Autodesk Maya.
