This process can get complex, but it all comes down to the concept of triangulation. Triangulation involves taking pictures from a minimum of two different locations. These pictures create lines of sight that lead from each camera to specific points on the object being photographed. The intersection of these lines plays into mathematical calculations ...
Since aerial photogrammetry is one of the most common methods, let’s take a look at how those photos get classified.
Vertical photographs occur when the camera axis is vertical. So, if you put the camera in an airplane, its lens would point down to the ground for a birds-eye view. Tilted photographs uses oblique photos, in which you can see ...
Moving out to a larger scale, space-based photogrammetry occurs with cameras either fixed on Earth, in an artificial satellite or positioned on the moon or another planet. In fact, photogrammetry was touted as a key part of space exploration even in the ’60s, and technological advancements have made it even more relevant. It can tell us about cloud ...
Images in support of terrestrial photogrammetry techniques are usually taken from a fixed position on the ground with a camera’s axis parallel to the Earth. Data about the camera’s position, such as its coordinates, are collected at the time the photo is taken. Terrestrial photogrammetry for surveying typically requires fewer resources and skilled ...
The process of photogrammetry can vary, but the general idea revolves around gathering information about an object from photos of it. The photos are taken from different locations and angles to allow for precise calculations that help analysts gather the data they’re looking for. Typically, they use things like photo interpretation and geometric ...
For centuries, photogrammetry has played a critical role in our understanding of faraway objects and the Earth’s surface. It’s uses have expanded over the years and have led to a powerful range of game-changing technologies in industries like construction, engineering, medicine and much more. Photogrammetry gathers measurements and data about an ...
During the COVID-19 pandemic, most industries have been unable to escape the urgent need to adapt services for an increasingly online world, and real estate, which has traditionally conducted business in-person and on-site, has certainly not been left untouched by this. The industry has seen the majority of renting and selling processes either put ...
Last year, we all found ways to do business a little differently. As COVID-19's impact was felt across the world, companies and people adjusted to living a more virtual lifestyle. For many businesses, this change acted as a catalyst, pushing ahead the digital transformation efforts that had been already underway. As we look to the future of retail, ...
