Cycles are the core principal of the universe, and are all pervasive. We are thoroughly enmeshed in cycles and the periodic rhythms, which span the frequencies of space and time. Some are of the most obvious on a daily basis: our sleep patterns, the weather, the seasons, sunrise, sunset, the moon phases, and more. On a larger magnitude: the age of our bodies, the rise and decline of species, the life cycle of stars. On a smaller, our breathing rate, our heart rate, the audio spectrum of music, speaking, the visible light spectrum, radio waves, cosmic rays, and ultimately the smallest measurable amount of time we can comprehend (Planck time). The appearance of the entire world and all existence with its natural and technological cycles are rooted in archetypal, sinusoidal principals.

What is Photogrammetry?

Photogrammetry is the process of creating 3D objects from 2D photographs. The process can be used to scan anything from objects and people, to architecture, terrain and landscapes. There are various strategies you can use when taking photos to produce accurate models. This document includes photography techniques, ideal camera settings and lighting, photogrammetry software, and further resources to create 3D models from photos.

Photogrammetry [noun] The science or technique for obtaining reliable information on the natural environment or physical objects by recording, measuring and interpreting photographic images.


Typical Outputs

A map, a drawing, a 3D model of a real-world object, scene, or terrain.

Remote Sensing, GIS, Stereoscopy

Main Tasks of Photogrammetry

Comparison to Laser Scanning (LIDAR)

Laser scanning is great in cases where photogrammetric techniques often fail – such as when objects have low texture, or shiny/reflective. However, laser scanning is expensive, time consuming, and can’t be used with moving objects like Photogrammetry can. That said, Laser Scanning and Photogrammetry can be considered complimentary to eachother.
