[0002] Road bridges are road facilities and buildings built to cross obstacles. With the development of road traffic and infrastructure, more and more road bridges are used at full capacity or even overloaded. In addition, due to long-term use, road bridges need to be maintained and inspected to evaluate their structural health.

[0003] In the inspection of road and bridge facilities, photogrammetry is often used. Basic photogrammetry is to use images taken by optical cameras to study and determine the shape, size, properties and mutual relationship of the objects being photographed. It is very intuitive and efficient in photographing and inspecting the overall deformation of bridges, cracks in bridges, etc.
