Abstract

A movable multi-view visual bridge conventional detection method includes the following specific implementing steps that A, an unmanned aerial vehicle device is erected, parameters are set, and a vehicle-mounted device is calibrated; B, a bridge structure three-dimensional model is scanned and established, and a flight route is determined; C, bridge conventional scanning and detection are conducted, and appearance pictures are transmitted and stored; and D, the bridge state is evaluated, and multimedia diagnosis is summarized.

Description

technical field [0001] The invention relates to routine detection of bridges using drones, high-definition cameras, and digital image processing technology. Background technique [0002] Bridges are the throats that ensure the smooth flow of roads, highways, railways, etc., and play an extremely important role in the transportation system. Bridge safety plays a pivotal role in national economic development. However, due to environmental corrosion, improper design, material defects, vehicle overload, and force majeure factors, bridge structures will be damaged to varying degrees. In recent years, bridge accidents in various places are mostly caused by lack of bridge inspection and improper maintenance. These damages will eventually lead to structural damage and even collapse of the bridge, resulting in significant loss of life and property. Routine bridge inspections can effectively detect early safety hazards, prevent the accumulation of damage, and avoid catastrophic acci...
