Earning money with photogrammetry: which is the best drone to invest in?

Photogrammetry is a technique that, through the analysis of aerial photographs, makes it possible to reconstruct surfaces and objects in 3D, providing detailed topographic data that is essential in a wide range of fields, including civil engineering, architecture and precision agriculture. With the advent of drones, collecting high-resolution images has become simpler and more accessible, making processes more efficient; however, to obtain accurate results it is essential to choose the right drone. Investing in a model optimised for photogrammetry ensures not only precision, but also efficiency and quality in every project.

In this article we will explore the best drones currently available for this technology.

1. Autel Evo II Pro RTK V3: quality and competitive price

The Autel Evo II Pro RTK V3 is the perfect choice for those seeking precision and advanced performance at an affordable price. Equipped with the RTK (Real-Time Kinematic) system, this drone guarantees extremely accurate image geolocation, essential for obtaining high-quality 3D models in photogrammetry. The RTK system also reduces the need for ground control points, making field operations faster and more efficient.

The 20 MP camera with a 1-inch CMOS sensor ensures sharp, detailed images, while 6K video recording lets you capture every fine detail with exceptional clarity. With a flight time of about 40 minutes and a range of up to 15 km, the Autel Evo II Pro RTK V3 is also ideal for covering large areas efficiently.

In short, this drone offers an excellent balance between performance and cost, making it particularly appealing for those looking for quality and precision without the need for an excessive investment.

2. Mavic 3 Enterprise: precision, compactness and versatility

The DJI Mavic 3 Enterprise is an excellent drone for photogrammetry, particularly suited to those looking for a compact, portable solution without compromising on quality. Equipped with a camera featuring a 4/3-inch CMOS sensor, it offers superior image quality compared to the Autel, mainly thanks to its greater ability to gather light. This makes it perfect for operating even in variable lighting conditions, such as at dawn or dusk.

The RTK system of the Mavic 3 Enterprise guarantees millimetre-level precision in image geolocation, reducing the need for ground control points and greatly increasing operational efficiency. With a flight time of about 45 minutes, one of the longest in its category, this drone can also cover large areas in a single mission, optimising working time.

The compactness and ease of transport of the Mavic 3 Enterprise make it particularly suitable for professionals who need to operate in hard-to-reach areas. Although it has a higher price than the Autel Evo II Pro RTK V3, the cost reflects the quality of the sensor and the better performance in difficult lighting conditions, making it the ideal choice for those who prioritise image quality and portability over savings.

3. Matrice 350 RTK: the top of the range

The DJI Matrice 350 RTK is the top of the range for those who need a robust and highly versatile drone for large-scale photogrammetry. Designed to handle even the toughest conditions, this drone is perfect for those who need to cover large surfaces or work in harsh environments. Its integrated RTK system guarantees millimetre-level precision, eliminating the need for ground control points and significantly improving the quality of 3D reconstructions.

One of the main strengths of the Matrice 350 RTK is its ability to carry a variety of sensors, including LiDAR, multispectral cameras and thermal sensors, offering extraordinary flexibility to adapt to different types of projects. This modularity makes it an excellent choice for those working on complex, multi-sector projects.

With a flight time that can exceed 55 minutes, the Matrice 350 RTK offers one of the best endurances on the market, allowing you to cover vast territories without interruption. Its robust, weather-resistant structure makes it ideal for operations in difficult environmental conditions, ensuring reliable performance even in rain or strong wind.

However, all this power and flexibility comes at a cost. The Matrice 350 RTK is significantly more expensive than models such as the Autel Evo II Pro RTK V3 and the Mavic 3 Enterprise, and it can represent a demanding investment. Nevertheless, for those who need an industrial drone capable of handling complex, large-scale projects, the Matrice 350 RTK justifies its high price with top-level performance, versatility and unmatched operational capability.

Conclusions

In conclusion, the choice of drone for photogrammetry depends on the specific needs of the project and the available budget. The Autel Evo II Pro RTK V3 offers excellent value for money, combining precision and advanced performance at a competitive cost. The Mavic 3 Enterprise excels in image quality and portability, albeit at a higher price, while the Matrice 350 RTK is the ultimate solution for large-scale projects, with a versatility and power that justify its higher cost.
