A high resoution orthomosaic helps you can clearly identify all the stone elements of an ancient road's pavement. It's really useful if it's required to remove the stones and, at the …
The first step of a "structure from motion" process is defining the "features points" of each image. These are points that the software is able to detect very well. It is also …
As you may have read before in this blog, i'm a huge fan of DIY (Do It Yoursef stuff). I lived my youth in a local Punk-Hardcore scene, so DIY was …
In structure from motion process, the software is able to generate a final report where it outputs the average value of the GSD, the Ground Sampling Distance. It's calculated based on …
The report that can be generated at the end of a photogrammetric processing contains all the steps that the structure from motion software did for you. It is very useful for …
If you need to proceed with an aerial photogrammetric survey on a construction site with work in progress, you may consider to take advantage of the lunch break to fly …
I had tested some indoor photogrammetry for 3D reconstruction of a square section artificial stream in an urban scenario. It was 2 meters heigh, 4 meters wide and 10 meter long. 100% …
It's better not to read the coordinates of a point from Google Earth and use them as Ground Control Point (GCP) in a structure from motion processing. Well, you can do …
I believe that drone aerial photogrammetry is the most effective technique for studying coastal erosion and coastal dynamics. And the main product to do this is the orthophoto. Where erosion progeresses vegetation …
I firmly believe that drone aerial photogrammetry is, at the moment, the most effective technique, considering how much it costs related to the benefits it provides, for the survey of …
