Paper Title:
A Geometric Correction Method in Survey of Geometry Properties of Discontinuities in Rock Masses
  Abstract

A new geometric correction method in processing close range digital photograph is presented. All the critical steps involved in the geometric correction method are briefed and discussed, including determination of Control Points (CP) on the exposure of the rock mass, projection of the 3-D CPs on the exposure of the rock mass to the projection plane, mathematically solving the transformation matrix, geometrically correcting and resampling the digital photograph. As an illustrative example, the whole process of application of the method for a specific digital photograph taken from an outcrop of rock mass is also presented. It is found that the new geometric correction method is effective and more convincing.
