Photogrammetry software review, thoughts and considerations before involving in photogrammetry

In this article we will review a few basic concepts regarding photogrammetry processing software.

What is photogrammetry and what are it’s appliances?

Photogrammetry is the science of making a measurement which are made from different type of photographs or pictures. This method is uses the parallax obtained between several pictures, made from different perspective. It can be used to record complex 2D and 3D motions. The best way it can be described is with the binocular human vision. Basically, every eye has it’s own point of view and when looking at an object in the space each eye measures between it and every point on the object. Afterwards this data is transferred to the brain, where it’s overlaid (when looking with 2 eyes you don’t see 2 point of views), the result is that you see one 3d image. Similarly, the process of photogrammetry collects the data regarding the shape, the volume, depth of a subject. After that this data can be used for recreating this model in digital environment. If we continue to follow the logic, this means that each and every object, which can be photographed (or scanned, because it can be done by laser, too) properly, can be transferred into digital model. These models can be used for whatever purposes needed – from creating topographical maps to models that can be 3d printed, used as models in movie and game industry and so on.

How does photogrammetry work?

Photogrammetry works by extracting the geometric information of a two dimensional image, which represents the two eyes of a human. In order to improve the accuracy, we will need more “eyes”, which transferred to our case means more points of view. All that said, as many photos we can get of an object, the more accurate result we will get.
Photogrammetry is the process used to create the digital 3D model of an object – area, place, location and pretty much anything that exists in the real world. Indeed, it is possible to make the 3D model of an object with several pictures of this object, ingeniously taken from different points of view, in order to get a complete representation of the object.

Photogrammetry in your hand

For this, you don’t necessarily need to use a 3D scanner – a simple smartphone, a tablet or a good camera can be used.
But the accuracy of the completed model mostly depends on the quality, angle and count of the photographs. If the count of the images is sufficient and is made from proportional angle and appropriate lighting, the photogrammetry result can be very good.

Deeper analysis of photogrammetry computing

So far, we have mentioned that using a set of images, we can extract geographical positions from them. Plain as it sounds, the processes could be rather computing intensive. Of course, you can do this on your laptop, personal computer. But the most accurate result you are after, the more complex hardware you will need. For large area photogrammetry recreations or very high detail scans, you might need hundreds of processors and tens of thousands of gigabytes of RAM if you want your scan completed in your lifetime. The process is gathering all the points from an image, combining it with the points extracted from every other image from your scan and with the predefined algorithm every photogrammetry software has to create the digital 3D model of your scan.
Usually, when you want something to be computed, it’s mostly a matter of waiting – day, week, month, etc. But this is not the case always. If your PC or laptop doesn’t have enough memory that photogrammetry scan requires – you might not be able to finish the process at all. And this is where our photogrammetry power cloud computing service comes in. We have all in store for you if you want your scans fast and easy, just for a fraction of the actual price.

What are the best photogrammetry software tools?

While choosing a photogrammetry priocessing software, you will have plenty of options. You will have to choose your software regarding your expectations: Do you need to upload several images? Do you want to focus on aerial images? Are you experienced? Do you want to try photogrammetry for the first time with a free software? Let’s see what is the best solution for you!
