Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle photography, in particular to a multi-rotor unmanned aerial vehicle aerial photography system designed for traffic and an implementation method thereof. Background technique [0002] Our country is a transportation powerhouse, and some transportation infrastructures are newly built or expanded every year, such as highways, municipal roads, ports, bridges and so on. The design stage is an important link in the construction of transportation infrastructure. Knowing the project site conditions can help designers better design project plans, and can compare and select plans to choose the best from multiple links such as economy, traffic volume, safety, and construction difficulty. route or best solution.

Problems solved by technology

[0003] At present, preliminary surveys are carried out in each design stage of transportation infrastructure. Taking expressway design as an example, data such as 1:50,000 topographic maps, Google Maps, and Tiandi Maps are mostly used in the route selection stage. Although to a certain extent It can obtain the site conditions, but the 1:50,000 topographic map is poor in expressing the details of the site conditions, and cannot clearly and detailedly show the site conditions. Google Maps and Tiantu can provide orthophoto images of the engineering site, but these The image data is not updated in time, and the image resolution is low, which is poor in timeliness and clarity. At the same time, it is impossible to have a three-dimensional understanding of ground objects only through orthophoto images

[0004] In the preliminary design stage, the design route of the expressway has been determined, and the 1:2000 topographic map will be measured along the design route. According to the topographic map, the preliminary design of the road can be completed. The 1:2000 topographic map can be used to understand the site conditions to a certain extent. However, in order to ensure the mastery of the site conditions, the designers will check the site environment and terrain conditions along the design route, which will consume a lot of manpower and material resources

At the same time, it is impossible for all designers and industry experts to check the site, so that it cannot be guaranteed that every designer and expert can grasp the site situation. At the same time, simple photography and manual recording methods are often used for on-site recording methods. cannot cover all information
