Abstract:

The rock mass discontinuities’ parameters measurement based on image processing technique is a new method which differs from the traditional measurements in many ways. It is usually composed of image determination, image processing and image analyses. This method takes common digital camera as a main tool to collect information of rock mass discontinuities and depends on computer to process image information. In this way the tunnel building face information of rock mass discontinuities’ parameters can be gained at fast. This paper made an entire and systemic study on the new method and developed a software to realize automation and intelligentize of processing. The real experimental evaluation of the typical rock mass image shows this method has better precision and higher efficiency. Therefore, we can conclude that the paper studied a new way of rock mass discontinuities’ parameters measurement.
