Description

Technical Field

[0001] The utility model belongs to the technical field of drone assistance, and relates to a portable roof-mounted drone pavement data collection assistance device. Background Technique

[0002] In recent years, drone technology has made remarkable progress and innovation. Not only has there been a significant improvement in aspects such as payload capacity, communication transmission speed, and data processing ability, but its application fields have also become increasingly extensive. In multiple fields such as aerial photography, agricultural plant protection, power line inspection, environmental monitoring, and express delivery, drones have demonstrated their unique value. In addition, in emergency situations such as emergency rescue, fire rescue, and medical rescue, drones have played an irreplaceable role.

[0003] In the highway industry, drones play a crucial role in field surveys. By combining aerial photography images with drone graphics processing software, we can generate oblique photography models, enabling designers to visually see the actual situation on-site in front of the computer. This provides them with great convenience, allowing them to flexibly adjust the plan according to the actual situation and optimize the road alignment and design the plan without having to go to the site in person.

[0004] However, in major and medium-sized road repair projects, the investigation of road surface diseases and the damage of traffic facilities is a challenge. Due to the complex road surrounding environment, there are obstacles such as trees, transmission towers, and utility poles, which will interfere with the flight of drones. Although high-altitude flight can avoid these obstacles, it often fails to meet the accuracy requirements for detecting road surface diseases and the damage of traffic facilities, and the clarity is insufficient. While ultra-low-altitude flight can improve the accuracy, it is affected by large vehicles on the road surface and is prone to safety problems.

[0005] Therefore, making the drone vehicle-mounted has become a feasible solution. This method can not only make full use of existing resources, including the mature software chain of drones, but also requires little additional investment. By being vehicle-mounted, we can effectively reduce the use of human resources, shorten the working time, and achieve better economic benefits. This innovative application method will undoubtedly bring new opportunities and challenges to the future development of the highway industry. Content of the Utility Model
