Three-dimensional bridge scene construction method and device

Abstract

The embodiment of the invention provides a three-dimensional bridge scene construction method and device. The method comprises steps of acquiring structure data of a bridge and environment data around the bridge, preprocessing the environment data around the bridge and acquiring modeling data of the bridge environment; according to the modeling data of the bridge environment, establishing a three-dimensional scene model of the bridge environment, and according to the structure data of the bridge, establishing a three-dimensional model of the bridge; and finally, fitting the three-dimensional scene model of the bridge environment and the three-dimensional model of the bridge and displaying. According to the invention, through the three-dimensional scene model of the bridge environment and the three-dimensional model of the bridge, the three-dimensional scene model of the bridge environment and the three-dimensional model of the bridge are fitted so that a three-dimensional bridge scene is constructed, so the obtained three-dimensional bridge scene is capable of displaying complex spatial structure information of the bridge, and displaying environment information surround the bridge, thereby facilitating that a bridge maintainer establishes a bridge maintenance scheme according to the actual environment where the bridge is located.

Description

technical field [0001] Embodiments of the present invention relate to the field of transportation technologies, and in particular, to a method and device for constructing a three-dimensional bridge scene. Background technique [0002] Expressway bridges are the key monitoring objects of the maintenance department. Due to the influence of factors such as the environment, overloading, man-made, material performance degradation, and management and maintenance not being in place in time, various parts of the bridge structure will have varying degrees of failure before reaching the design period. damage and deterioration. The traditional method of displaying bridges is to display them in the form of dots on a two-dimensional map, while bridges have a complex spatial structure. In a two-dimensional map, neither the spatial information of the bridge nor the environmental information around the bridge can be displayed, and the location of bridge diseases cannot be determined.
