How to choose aerial testing drone? Aerial testing drone, as a professional branch of the industrial dronefamily, is often prohibitive to many friends who want to buy it because of its high cost, professional personnel, high requirements for flight control and complex post-processing software.
But the drone aerial relative to manual measurement, advantage is not simple is the issue of efficiency, but a question of market orientation, the aerial market sooner and can obtain valuable experience in aerial, means a broader business to undertake, in today's traditional surveying and mapping market changes, timely contact with the aerial, surveying and mapping industry to open another door.
Should I choose a multi-rotor aircraft or a fixed-wing aircraft?
A: What kind of drone to choose depends mainly on the scope and use of the shooting area.
1, the advantages of multi-rotor: light, relatively low cost, can be fixed hovering
Suitable direction: aerial photography, environmental monitoring, detection, transportation of special objects and other small area applications
2. Advantages of fixed wing: long endurance, good wind resistance and wide shooting area
Suitable direction: aerial survey, regional monitoring, pipeline patrol, rescue and relief, emergency communication and other large area applications
How many people do the aerial survey and how long does the training take to complete the project?
A: It takes 2 people to complete the field flight, one person for each ground station and one person for each flight controller. Now, with the improvement of the flight control system, individual operations are no longer far away, and the number of personnel can be equipped according to the specific requirements of the project.
Drone aerial survey system, field aviation flight training time is generally 3 days; Post-processing software needs to see the final type of results, the training time is different, now commonly used general empty three using INPHO, vertical test using MapMatrix, DOM production using EPT.
Can the accuracy meet the requirements?
A: General aerial survey drone can meet the DOM/DLG aerial photography requirements of 1:1000 and 1:2000 resolution, and can meet the aerial photography requirements of 1:500 resolution in the plain area. However, the accuracy is also restricted by camera and post-processing and other factors. Generally, the elevation accuracy is 1:500, and the control is not good.
What are the steps of drone aerial survey?
A: First, the flight area and mapping requirements should be determined, and the phase control point should be done. Then, the flight route can be edited in the ground station according to the requirements of the survey area, and appropriate meteorological conditions (weather, light, wind, cloud height, and visibility) can be selected to arrive at the scene for aerial photography.
