Bridge alignment monitoring system and bridge alignment monitoring method

Abstract

The technical scheme of the invention provides a bridge alignment monitoring system and a bridge alignment monitoring method. The bridge alignment monitoring system comprises: a plurality of targets which are arranged under a bridge, wherein the distances between the targets and the bridge surface of the bridge are different; image acquisition devices which are distributed at two opposite ends of the bridge and are used for acquiring images of the target from two different visual angles at different moments; and image processing equipment which is used for performing feature value extraction on the images of the targets, determining coordinate change values of the targets at different moments based on the feature values extracted from the images acquired at different moments, and fitting the coordinate change values of the targets to obtain the line shape of the bridge. The image acquisition device can acquire the image of each target in real time at a certain frequency, so that the image processing device can perform data processing in real time to fit the linear curve of the bridge. The whole process does not need manual participation, manpower and material resources can be greatly saved, and real-time automatic linear monitoring of the bridge is achieved.

Description

technical field [0001] The embodiments of the present invention relate to the field of data monitoring, in particular to a bridge alignment monitoring system and a bridge alignment monitoring method. Background technique [0002] As an important indicator for judging the overall structural performance of bridges, the alignment of bridges has always been the focus of attention in the industry. Especially for long-span bridges, the linear index can better reflect the quality of the overall structure of the bridge. At present, the monitoring of bridge alignment mainly uses instruments such as theodolite, level or total station to measure the elevation of different points to measure the bridge alignment. However, these methods consume a lot of manpower and material resources, and are not suitable for long-term monitoring of bridge alignment.
