Some people often ask, what should an ideal mapping drone look like? I don't have the practical experience to dare to talk about it, but the use of drones in the field of surveying and mapping has been relatively mature and extensive. The UAV channel interviewed a number of first-line operators and industrial drone manufacturers. —MMC UAV. 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 surveying and mapping drones in the industry is very expensive, and the equipment used for tasks such as three-dimensional surveying and 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 from MMC said that the fixed wing has a long life and fast speed and is suitable for large-area operations. In this respect, MMC owns the Griffion M8 VTOL fixed-wing drone, which has a cruising time of up to 150 minutes and a flying distance of 200KM, which can be applied to most surveying scenes.
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. If you are using a multi-rotor UAV for surveying, it is recommended to use the MMC Skylle 1550 drone. This drone has a 81-minute battery life, a 12KG load and a communication distance of up to 20Km, which can effectively expand the outdoor working range.
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 thrown up by hand, 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.
6.portable, easy to deploy
The outsiders also hope that the drones are portable and easy to deploy. Because some of the missions are in poor condition and the vehicle is difficult to pass, it is necessary to carry the drone 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.
