A Method of Automated Registration of Tunnel Wall Image and Detection of Tunnel Wall Deformation

摘要

We are developing an automatic image processing algorithm to extract deformations like cracks and diagnose tunnel conditions. As the first step for this purpose, it is indispensable to register plural images accurately and effectively from continuously scanned images of tunnel wall. Because there are problems in the accuracy and work efficiency in the manual image registering process to appropriately align corresponding points, a method is proposed to automatically perform this process.
