![]() Large cameras, like DSLRs, with large image sensors (not necessarily more megapixels) collect more light and yield better results than cameras with small image sensors, like those found in mobile devices. Choosing your CameraĮvery camera has an image sensor that acts like a net for catching light, and the more light you catch the better. Scaling models becomes increasingly important when you bring multiple photogrammetric objects together into the same immersive environment. If you don’t provide your photogrammetry software and the 3D reconstruction with a known distance from the subject, the scale of the 3D model will be completely arbitrary.įor example, a human’s 3D reconstructed shoe will look correct as a model, but if you don’t tell your software the shoe’s actual scale once you put it into an augmented reality or virtual reality environment it may be the size of a car. This reference distance is fed into photogrammetry software, resulting in a properly scaled model. Measuring tape (optional, but recommended)Ī measuring tape is for taking a distance measurement (or two) from the subject object or environment. Basic EquipmentĪny digital camera or mobile device will work, but the larger the camera sensor the easier it is to produce a high quality photogrammetric reconstruction, as explained below. There are other tutorials already available for the software of your choice. Note: This guide will not take you through software workflows because there are many different pieces of photogrammetry software available. Included are advanced tips on how to use plexiglass for capturing all surfaces of an object, and how to incorporate a ring flash as a portable and powerful light source. So you can follow along, this guide has been designed to show how to apply the photogrammetry photography process to common objects, structures and landscapes, demonstrating what works, why it works, and what doesn’t work, and why it doesn’t work. Photogrammetry software designed for processing these image sets is then used to produce three-dimensional models of structures, landscapes, objects (like the 3D shoe on the right) and two-dimensional aerial imagery. Photogrammetry involves capturing multiple images of an object, structure, or landscape, with overlap, and from different perspectives.

Audiences can now step into a story, interacting with story-significant objects and environments in ways not possible with two-dimensional videos and photos.ĭownload this GuideThe photogrammetry process dates back to 1849 and Aimé Laussedat, who used the technique for creating topographic maps. It enables journalists and storytellers to digitize pieces of the physical world for creating immersive and experiential stories that are three-dimensional, and native to the human’s three-dimensional perception. Photogrammetry provides a bridge from the physical world’s reality to digital immersive realities. ![]() ![]() Humans perceive and experience the world in three dimensions.
