Abstract
In order to solve the measurement problem of the shield tail clearance in the shield construction, the shield tail clearance automatic measuring system which is based on digital image processing technique has been developed in this paper, hardware and software are both designed in this system, and the image features can be extracted by image enhancement, thresholding and edge detection which are digital image processing technology, and the clearance is calculated. Field tests show that the system has a friendly interface and is easy to be operated .What is more, the clearance can be measured automatically with high accuracy and stable performance, It provides security for the shield construction.
