How Does 3D Aerial Mapping Function?

Companies in the oil and gas business may profit greatly from 3D modeling since it makes it simpler for them to plan and be certain that any assumptions they make are valid. The use of unmanned aerial vehicles (UAVs) for data collection is an excellent method for creating 3D models (UAVs). This article will walk you through the process of creating the 3D aerial mapping.

Examine the Circumstances

However, even if you use the most modern equipment and follow the finest practices, it won't be able to compensate for bad conditions while doing the 3D aerial mapping. Consider the best time of day to fly your drone to acquire the data you need for your 3D models before scheduling your flights. 

 

The best time to fly is about noon when the sun is straight above and casting the fewest shadows. When flying in the early or late hours of the day, shadows might tamper with the model's precision.

 

The quality of your images may be impacted if you don't check the weather prediction for the day you want to fly. Flying may be more challenging if it's raining or windy, whereas a sunny day will cast longer shadows. Flying is most enjoyable on an overcast day.

Images of the Nadir

When doing 3D aerial mapping, the initial photos your drone should capture are known as nadir shots because they show the ground or building below as seen from directly above. Your 3D models will be built on top of these pictures. 

 

Automated flight plans for your drone to take nadir images are usually straightforward. To collect photographs, all you have to do is let the drone fly along the path you've specified and it will do the rest.

Take Pictures from Unusual Angles

Looking at a feature from above may not provide you with the finest perspective if you're attempting to get a 3D image of it. The nadir images may be sufficient if you're looking at a relatively level area of terrain. 

 

However, if you're modeling a building or terrain with a range of heights, you'll want to include oblique views in addition to your original nadir shots. If you just utilized nadir photographs, you would have missed important information that may be seen in oblique views. 

 

Typically, you would fly your drone in a circle around the location with the camera oriented at a 45-degree angle to acquire these shots.

Create a model using the images that you've processed

You may utilize processing software to patch together several photos taken from different angles to create a single 3D model of the feature you were scanning. With the correct software, your photographs might be turned into a working model in as little as an hour.

What is Serval aerial mapping and what is used for?

In this part, we are telling you about survey aerial mapping. Aerial surveying is the use of airplanes, helicopters, unmanned flying vehicles (UAVs), balloons, or other aerial techniques to collect geomatics or other imagery. 

 

Aerial photography, Lidar, and remote sensing (which employs numerous visible and invisible wavelengths of the electromagnetic spectrum, such as infrared, gamma, and ultraviolet) may all be used to collect data, as can geophysics (such as aeromagnetic surveys and gravity).

 

An aerial view of a region may also be used to generate a chart or map of the area. Because of its higher resolution, quality, and atmospheric circumstances, aerial surveying should be separated from satellite imaging technology (which can negatively impact and obscure satellite observation).

 

Photogrammetry in which the camera is positioned in the air has become interchangeable with aerial surveys in today's day and age. Measurements may be taken from aerial pictures using photogrammetric techniques and procedures. It is feasible to survey territory that would be difficult or prohibitive to scan on the ground using aerial surveying, also known as photogrammetry. 

 

Anyone can learn 3D aerial mapping if they put in the time and effort to learn about and practice the technique. Even if you don't have time to learn how a 3D aerial mapping partner with expertise can assist. To get started, get in contact with us at Sandpoint right now.
