Description

Technical Field

[0001] The utility model relates to the technical field of surveying and mapping unmanned aerial vehicles, in particular to an anti-vibration carrying platform of a surveying and mapping unmanned aerial vehicle. Background Art

[0002] With the rapid development of science and technology and the increasing maturity of UAV technology, UAVs have been widely used in various fields, especially in the field of surveying and mapping. UAVs have become an important tool for drawing high-precision maps and reconstructing three-dimensional models. Surveying and mapping UAVs have significantly improved the efficiency and accuracy of surveying and mapping work with their high-precision, multi-angle image acquisition capabilities. Surveying and mapping UAVs are generally equipped with corresponding mounting platforms. During specific installation operations, the surveying and mapping equipment is installed on the mounting platform to achieve fixed installation operations.

[0003] However, during the flight, especially in complex terrain and harsh weather conditions, drones are easily disturbed by external factors such as wind and airflow, which causes the fuselage to vibrate. After the fuselage vibrates, the vibration will be transmitted to the mounting platform, causing the mounting platform to vibrate. Since the surveying and mapping equipment is installed on the mounting platform, the vibration of the mounting platform will further affect the stability of the surveying and mapping equipment, such as (cameras, sensors, etc.) cannot remain stable, which in turn affects the quality and accuracy of data collection and brings inconvenience to users. In view of this, we propose an anti-vibration mounting platform for surveying and mapping drones. Utility Model Content
