Recently, some netizens have left a message asking what the ideal mapping drone should look like? The author does not dare to talk about the actual operation experience, but the use of drones in the field of surveying and mapping has been relatively mature and extensive. The UAV channel of the World Wide Web has interviewed many practitioners in the first-line operation. Among them are flying hands and technicians.
1 stable and reliable
Several practitioners first mentioned that they should be stable and reliable, and no one wants the equipment to drop the chain at a critical moment. Moreover, the cost of UAVs used in the industry is very expensive, and the equipment used for tasks such as 3D mapping is more expensive, and the economic loss of falling is very large.
2 long battery life
Everyone also mentioned that the battery life is longer, because the frequent take-off and landing time also increases the risk. The long battery life means higher work efficiency and higher safety.
3 multi-rotor or fixed wing?
In the field of surveying and mapping, there are two types of drones, fixed-wing and multi-rotor, which are more practical.
A technician said: The fixed-wing has a long life and fast speed, which is suitable for large-area operations.
The multi-rotor's take-off and landing is more convenient and cheaper, and is suitable for small-area operations. Three-dimensional modeling operations such as tilt photography are small plots, and generally multi-rotors are also used.
4 high precision
The introduction of flying hands in the first-line operation, the surveying and mapping industry has higher requirements for precision. Using RTK technology can achieve centimeter-level accuracy, without having to play too many phase control points, can greatly reduce the workload in the field.
5 takeoff and landing is convenient
The flying hand of the first-line operation also requires the drone to take off and land conveniently. According to the introduction, the general fixed-wing can be ejected or hand-pulled, and the landing is parachute. However, some places with complicated terrain cannot meet the requirements of the aircraft's take-off and landing, and the drone has the ability to take off and land vertically.
6 portable, easy to deploy
The outsiders also hope that the drones are portable and easy to deploy. Because of the poor road conditions and the difficulty of vehicles, it is necessary to carry drones on foot. In addition, if the aircraft is small and can meet the demand, it is convenient to hold the normal work.
7 load? Basically no requirement
Everyone has not asked for the load. According to the introduction, the equipment used for surveying and mapping is mainly micro-single and SLR cameras, and the load of 1 kg is enough. However, some mapping drones equipped with lidar have load requirements. LIDAR, IMU, and camera add up to about 5 kg.
