How Is Photogrammetry Used in Video Games?
One of the lesser-known applications of photogrammetry is in video game design. Many video game developers employ this measurements-from-photos technology to create all kinds of 3D models that are then used as in-game assets. These could range from small, handheld objects such as bottles or firearms to large-scale environments such as cityscapes or mountains. There […]
Photogrammetry vs 3D Scanning
Digital 3D models are used in a variety of industries, but there is more than one method to create them from a real object or scene. Photogrammetry and 3D scanning are the two primary methods for creating these models. Whether you need 3D models for design, manufacturing, forensics, or research, below are the pros, cons, […]

Low-Cost Cameras for Photogrammetry and Measurement
What makes a good low-cost camera for photogrammetry? Photogrammetry is the technique of using a camera to measure and model the real world. First note that low-cost is a relative term – we are not talking about a $150 camera – instead of between $500 and $900. This is more aptly titled: “What is the […]
Accuracy of Pile Volume Measurement with Photogrammetry
Accurate volume measurement of piles of material is important in a number of applications, such as: stock pile inventory management, volumes of tailing piles, volume of organic materials in composting operations, quarry pit size, mine reclamation, etc. These piles are difficult to measure due to their size, difficulty of traversing, and non-uniform shapes. The advent […]
