Abstract

The invention discloses a road and bridge three-dimensional reconstruction method and apparatus based on an unmanned aerial vehicle. An image acquisition system is carried by use of the unmanned aerial vehicle, sequence image data of roads and bridges is acquired through control of flight of the unmanned aerial vehicle, a road and bridge surface grid model is obtained through a subsequent image data processing process, and thus a basis is provided for treatment of road and bridge damage. Since the road and bridge surface grid model is constructed by acquiring the image data of the roads and bridges on the basis of the unmanned aerial vehicle, the road and bridge inspection period is greatly shortened, and traffic passage is not affected.

Description

technical field [0001] The present application relates to the technical field of road and bridge inspection, and more specifically, to a method and device for three-dimensional reconstruction of roads and bridges based on drones. Background technique [0002] In recent years, with the rapid development of the transportation industry, especially the surge of overweight (overweight, overheight, overwidth, and overlength) vehicles, road damage and bridge cracking have seriously threatened the safety of roads and bridges. Bridge collapse accidents have occurred frequently in recent years, causing serious losses of people's property and lives. [0003] At present, road and bridge maintenance companies still use conventional methods to inspect roads and bridges. In most cases, they still use bridge inspection vehicles to cooperate with manual inspections. However, this method generally has problems such as long inspection cycles, low efficiency, and affecting traffic flow. Conte...
