What kind of drone is suitable for accurate aerial photography

DJI (DJI) is currently the best company in consumer drones, with a market share of more than 70% in the global drone market. DJI's Phantom 3 series products have detonated the entire consumer drone market, and now the latest drone under 10,000 yuan is the Phantom 4, with a flight time of up to 28 minutes, and the effective flight time is about 25% higher than the previous generation. Image transmission and flight control distances of up to 5 kilometers allow you to fly and shoot with confidence.

On the basis of Phantom 3, Phantom 4 has been comprehensively improved, and the three innovative functions of "Obstacle Perception", "Intelligent Following" and "Pointing Flight" have become the biggest highlights, allowing the drone to truly combine with artificial intelligence. More than 10,000 yuan has the "Enlightenment" Inspire1 dual control version, which can be equipped with Zenmuse X5 camera, with powerful imaging capabilities hidden in a compact and lightweight body, which can shoot high-quality 4K** and 16 million pixel DNG lossless format**. The Zenmuse X5R captures 4K** in lossless format, recording full image detail and providing more space for post-processing, making it the ideal partner for professional film and television production.

It depends on the individual needs.

There are several main aspects of UAV mapping that need to be paid attention to:

Requirements for the accuracy of specific surveying and mapping projects.

The flight altitude, distance, and flight time of a single battery of the drone.

Pixels of an aerial camera.

Processing of phase control points and later torques.

The cost of repairs after the drone is damaged.

In fact, there are quite a few DJI drones that can meet the surveying and mapping standards, mainly depending on the requirements of your specific project, the higher the accuracy requirements, the higher the requirements for the drone, and the higher the cost will be.

Enlightenment"The Inspire Series Matrice 100 is pretty good.

Note: In fact, the requirements for UAV aerial photography are relatively low, mainly because the requirements for camera and inner page processing are relatively high.

As long as it is a drone, it can be used for mapping, the difference is only in the pixel accuracy of a camera, the better the pixel, the higher the measurement accuracy. Of course, this is only relative to the comparison of UAVs of 10,000 yuan and 1,000 yuan, and the UAVs that reach hundreds of thousands of yuan are specially used for surveying and mapping, and all the functions are not available in 10,000 yuan UAVs, such as control points can be set up for measurement like RTK, infrared scanning, and so on. However, the drone is only a pre-operation process, and the most important thing is post-software processing.

DJI does not focus on surveying and mapping drones, industrial-grade surveying and mapping drones, DJI has M600, but the endurance is too short and the efficiency is too low.

Strictly speaking, no, professional surveying and mapping cannot use multi-axis, because it cannot achieve long-endurance time, and fixed-wing aircraft are generally used to mount cameras for surveying and mapping.

Of course, if you don't want a formal surveying map, you can take a few photos in a small area.

It can be converted by proportion. UAVs have many uses, aerial photography is just one of them, and there are many uses such as agricultural plant protection, power inspection, geological exploration, etc.

DJI Phantom 2 standard battery: 5200mAh lithium battery, maximum flight speed: 15m s, flight time: 10-15 minutes, according to this calculation should be kilometers, remote control about 2 kilometers.

However, it is advisable to fly within visual range, which is within 500 meters, for safety reasons.
