BRIDGE KEY COMPONENT DISEASE EARLY-WARNING SYSTEM AND METHOD BASED ON IMAGE MONITORING DATA

摘要

A bridge key component disease early-warning system and method based on image monitoring data. The system comprises an image collection and data transmission system, an image processing system and an assessment early-warning system. The image collection and data transmission system consists of high-definition cameras, a solar module, an auxiliary light source, a wireless transmission network and a data receiving end; the high-definition cameras are provided on key structure parts of a bridge, and image data is collected according to a certain frequency and transmitted to the data receiving end. The image processing system has the functions of automatic reading and optimization of a high-definition image and disease recognition and classification, and achieves machine vision analysis on monitoring component operation quality. The assessment early-warning system performs tracking and condition evaluation on the development of a possible disease by using a disease binary image as a research object, and if the disease development rate and severity exceed a threshold limit value, an early-warning is given. Automatic monitoring of bridge key components is achieved, and the early-warning system and method are of great significance in ensuring the safety of the structure.
