説明
The replica film method introduced by Suzuki and Takahashi (1994) is one of methods for observing microstructures in rocks, such as pores and cracks. In order to obtain the adequate image to extract microcracks on the replica film by image processing, we firstly propose a improved method for observing microcracks. The transmitted light is used in the ordinary method, while the reflected and refracted light is used in this proposed one.<BR>Then the procedure and accuracy of image analysis is discussed to quantitatively evaluate the frequency distributions of crack orientation and length. The results show that the adaptive binarizarion method is suitable for extracting microcracks from these images. Further we point out that the action of line detection operators depend on the direction of cracks. Therefore these operators should be performed to the images from various directions. Based on these investigations, we make a procedure of image analysis for extracting microcracks. The frequency distributions of crack orientation, crack length and total crack length obtained from this procedure have similar tendency for that to be made by hand.
