Photogrammetric processing as a multi-stage challenge<\/h2><\/div>

Many novice operators fall into the trap of thinking that the key to success is solely in the moment of the drone launch itself. In reality, professional photogrammetry is an interconnected vessel of two phases that already begin in the field, because that is where the quality of the final product is decided. In this phase, we need to precisely choose the exposure parameters and stabilize and measure the photopoints (GCPs) that become the reference points for our model in the actual geographic space. <\/p>\n

Only in the next step does the process move to the computer screen, where terrain interpretation takes place in office conditions. Instead of manually measuring hundreds of points in harsh weather conditions, we use software that analyzes millions of pixels to create a dense point cloud, orthophotos and precise 3D models.<\/p>\n<\/div>

Drone as a precision measurement tool<\/h2><\/div>

Choosing a drone for engineering purposes is a decision that goes far beyond analyzing drone-controller communication range or flight time. For us to talk about reliable data, we need to pay attention to two systems that distinguish hobby devices from professional work tools. <\/p>\n
