Research On Inspection Technology Of Tunnel Disease Based On Panoramic Vision

摘要

In order to solve the general exist problems of visual based tunnel disease inspection such as low level of automation and intelligence, using a high cost performance tunnel disease inspection device to have high precision automatic analysis and evaluation on the face of tunnel across time and space, the article designed a disease inspection technology for the whole section of tunnel. First designed a Panoramic visual sensor which can fast access the panoramic image of the whole tunnel section, and then through digital image processing technology, have high-precision automatic analysis and assessment on tunnel panoramic images, identification and classification on diseases, and provide metadata support to the analysis of the dynamic change of the developing tunnel disease across time and space. The experimental results showed that the visual based tunnel disease inspection can accurately and quickly search the tunnel diseases, automatically detect and have judgments and assessment on various defects exist in tunnel.
