How does UAV realize aerial photography application? What equipment do you need?

Hello, the implementation and control scheme of aerial survey UAV is recommended to you, and I hope you will be satisfied.

First, the advantages of aerial survey drones

Compared with traditional surveying and mapping, UAV aerial survey system has the advantages of low cost, flexibility, diverse loads, wide use, simple operation, safety and reliability, and plays an increasingly important role in modern surveying and mapping industry.

Second, the working principle of aerial survey UAV

It is controlled by radio remote control equipment or airborne computer program control system, and uses a small digital camera (or scanner) as airborne remote sensing equipment.

Third, aerial survey UAV flight platform

1. System composition

Flight platform, flight navigation and control system, ground monitoring system, mission equipment, data transmission system, launch and recovery system, on-site support equipment and ancillary equipment.

2. Performance index requirements of flight platform

A) the task load should be greater than 2kg.

B) The size of the mission module shall be larger than 625px (length) ×500px (width) ×625px (height);

C) the cruising speed is 60-160 km/h;

D) The service ceiling is 3000m; Above sea level;

E) The battery life is greater than1.5h; ;

F) Wind resistance rating should be greater than Grade 4.

Fourth, the flight control system of aerial survey UAV

1. System composition

Flight control system is used for navigation, positioning and autonomous flight control of UAV, and consists of flight control board, inertial navigation system, GPS receiver, air pressure sensor, airspeed sensor, speed sensor and other components.

2. Flight control system performance index requirements

A) The number of waypoints should be greater than100;

B) The weight should be less than 2kg;

C) Flight attitude control stability: the roll angle should be less than 3, the pitch angle should be less than 3, and the heading angle should be less than 3.

D) Track control accuracy: the yaw distance should be less than 20m, the height difference should be less than 20m, and the track curvature should be less than 5.

Five, aerial survey UAV ground monitoring system

1. System composition

Radio remote controller, monitoring computer system, ground power supply system and monitoring software.

2. Flight control system performance index requirements

A) The host of the monitoring station shall be a reinforced notebook computer or a computer and electronic equipment with the same performance;

B) The hardware of the ground monitoring system should be integrated, easy to disassemble and assemble, and easy to carry and carry;

C) Monitoring data can be displayed in both graphic and digital forms, and the display should be comprehensive, intuitive and practical;

D) The number of channels of the radio remote controller should be more than 8 to meet the use requirements;

E) The monitoring computer shall meet certain waterproof and dustproof performance requirements, and can work normally in the harsh environment in the field;

F) The main frequency and memory of the monitoring computer shall meet the requirements of the monitoring software for the computer system;

G) The power supply system shall ensure that the continuous working time of the ground monitoring system is more than 5 hours.

Seven. Safety requirements of aerial survey UAV

1 UAVs should be equipped with parachute equipment. When the UAV encounters sudden failure, the parachute can slow down the descent speed, avoid or reduce the impact and damage to the ground target, and reduce the damage to the flight platform and airborne equipment.

2. The designed flight altitude should be higher than the shooting area and the highest point of the air route 100m or more;

3. The total range of the designed route is less than the farthest range that the drone can reach;

4. The distance from military and commercial airports must be above 10km;

5. The landing site is relatively flat with good visibility;

6. Away from densely populated areas, there can be no high-voltage lines, tall buildings and important facilities within a radius of 200m;

7. There should be no obvious prominent rocks, ridges and stumps on the ground of the landing site, and there should be no ponds and large ditches.

8. There should be no interference sources such as radar stations, microwave relays and wireless communication in use nearby. In case of uncertainty, the frequency and intensity of the signal should be tested. If it interferes with the system equipment, it is necessary to change the landing site;

9. If the UAV takes off and lands by taxiing, the taxiing road surface conditions shall meet its performance requirements.

Eight, aerial survey drone camera equipment

At present, the payload of fixed-wing UAV provided in the market generally does not exceed 5Kg. Therefore, this kind of UAV can not carry the advanced aerial camera of 100 kg commonly used by manned aircraft. At present, most of the high-end SLR cameras are used, and the image frame is above 3K×4K.

Nine, aerial survey UAV selection reference

Because the complexity of unmanned aerial vehicle (UAV) required for aerial survey is higher than that of general model aircraft, all equipment should have good compatibility. Therefore, it is difficult to assemble and debug the equipment alone, and there are certain risks in the compatibility between the equipment. Buying a complete set of equipment is the best choice. It is suggested to choose Kunming Jinying Aerial Survey UAV Company, mainly due to the following factors. This company specializes in the design, production, sales, aerial survey and aerial photography services of aerial survey UAV equipment, and is the top design and manufacturing service provider of aerial survey and aerial photography UAV in China. It has the characteristics of good effect, high precision, strong technology, fast speed and high level. Is a leader in the industry, has been to Africa and other countries with harsh natural conditions for foreign aerial photography, successfully completed the aerial survey task! It has the only professional training ground for model airplanes and drones in Yunnan Province, including senior coach of Yunnan Model Aircraft Team, professional training for drones, air force air traffic control policy propagandist and formalities handler. As long as it does not affect civil aviation, military secrets and flying out of national borders, aviation can be approved and supported.

Accuracy guarantee of aerial survey

1. Accuracy is easier to reach the standard. People in some places can't go, or their quality or sense of responsibility is not good. The aerial survey covered the whole area without any omission.

2. Aerial survey can also make orthophoto map of the whole area. Man-made survey can only draw lines.

Problems of aerial survey

Ultra-high income has preconditions: that is, it requires upfront investment, the courage and courage of entrepreneurs, and the support of professional aviation.

1. Initial investment: 300,000 *2 UAVs = 600,000, and 200,000 ground stations and training, totaling about 800,000. Enterprise preparation.

2. Flight risk: Because Yunnan is located in the mountainous area, the airflow is complex, and the flight and runway conditions are bad, the probability of falling off the plane is higher than that in the plain area, and each fall will generally cause thousands or tens of thousands of yuan of losses. Jinying UAV supports reducing this loss of enterprises.

3. Aerial photography qualification: surveying and mapping enterprises and institutions with good conditions and scale. Guidance and assistance of jinying unmanned aerial vehicle.

4. Air Force Air Traffic Control: Jinying UAV is a model UAV coach and air traffic control policy propagandist. Jinying UAV can voluntarily go through the formalities of air traffic control declaration.

5. Flight technical experience: Jinying UAV is a leading provider and service provider of aerial survey equipment in China, and its rich experience and superb technology ensure the completion of the flight.

Aerial survey advantages of jinying UAV;

1, mature aerial photography experience and indoor experience, many aerial surveys in the province and at home, and successful aerial surveys in Africa.

2. The leader of the remote control flying hand, installation and maintenance is the eagle, and the winner of the silver medal in the National Model UAV Competition.

3. Build a strong base for model airplane drones, train long-range flying hands and test drones.

4. Qualification of aerial photography of Provincial Bureau of Surveying and Mapping.

5. Policy propagandist of Air Force Air Traffic Control Committee and air traffic control applicant.
