First- Overview of UAV surveying and mapping Companies around the world not only integrate drones into their daily workflows, but they also rely on data acquisition capabilities provided by drones because they save a lot of time and money compared to traditional data acquisition methods. While industry-leading manufacturers such as DJI and senseFly are still the front-runners, 84% of UAV mapping is now available on drone models priced at $1,500 or less. Most mapping uses an affordable quadcopter drone model, thanks primarily to advances in drone hardware and battery life, which were previously only available on more expensive drone models. However, compared with consumer drones, industrial-grade UAVs have advantages in terms of hardware and battery life. Chinese industrial drone manufacturer MMC is in a leading position in industrial drone development, whether in no Human-machine mapping applications still have corresponding solutions in the fields of public safety, fire protection, emergency rescue, inspection, etc., and their R&D and production of hydrogen fuel drones can last up to 4 hours, while vertical take-off and landing The drone's Griffion M8 has a lifetime of 81 minutes. Compared with the application of consumer-grade drone mapping and small scenes, industrial-grade drones are more suitable for large-scale land mapping, such as land resources, boundary mapping, water mapping, etc. Wait. At the same time, industrial-grade drones can be used in a variety of complex environments. Now, drones can easily capture data, making it easy to model, manage, and share data across a variety of software platforms, making it a resource for GIS analysts, surveyors, and pilots. Clearly, drone mapping provides faster, more accurate decisions for key business stakeholders by providing fast aerial data. Second-the status quo of UAV surveying and mapping Compared with traditional terrain mapping and image aerial photography methods, UAV mapping can save more than three times the time and cost. Data collection, which may have taken days or weeks, can be completed in a matter of hours and quickly completed modeling analysis. Companies are integrating aviation data into their workflows to streamline operations and increase efficiency. Although the regulatory compliance, safety, and training of drones are still an obstacle to development, the commercial drone industry has reached a critical point, and the impact of drones cannot be ignored. Drones are more than just toys for lovers. They are powerful data collection devices that can change the way many companies operate, providing a return on investment for companies large and small. Third- the trend of UAV mapping technology When do drones freely enter low-altitude airspace, making them an important part of our daily lives? The new UAV mapping application is booming in different industries, and the application of new technology makes our mapping and mapping work easier and more interesting. Fourth. UAV mapping opportunities and challenges Consumer drones are becoming more mainstream, and commercial applications are growing in all walks of life. Although there are still obstacles in terms of security, privacy, and insurance, there is no sign of a slowdown in the global drone market. The drone market has grown rapidly in recent years, with annual sales of drones growing at record levels. UAV surveying and mapping has many advantages such as high precision, high speed, and low cost. UAV surveying and mapping data products have short production time, strong timeliness and high resolution. They have been widely used in land mapping, planning and design, as well as rescue and disaster relief. The current aerial photography technology of drones also has obvious shortcomings: first, the smoothness of flight is not good. This happens to be triggered by the "advantage" of "light body". Second, sensor technology should be improved. Due to technical limitations and requirements, ordinary UAVs are currently unable to carry high-precision sensors, so the information and images with high precision required for surveying and mapping of large scales cannot be met. Finally, it is too dependent on the communication system. Because the control program of the drone is highly dependent on the GPS and the communication system, on the one hand, it is affected by the topographical factors during the execution of the aerial survey task; on the other hand, there are also security concerns, and the hacker can interfere with the coding program. The normal flight of the drone.
