Abstract
Borehole television, as one of investigation techniques with visual image, is used to investigate borehole walls as a continuous man-made outcrop, and to recognize in-situ rock mass conditions. It has been utilized as an useful method to analysis slope stability and to predict behavior of large rock cavern. Borehole image processing system (BIP System), as of the borehole television method, has been developed owing to the rapid advancement of microprocessors and other electronic devices, which can present images of borehole walls directly as digitized color signals at sites.
This paper describes an unique technique of image processing in BIP System, and presents some case histories of detecting discontinuities in rock masses automatically using common method for image recognition.Future view of image processing technique for geological informations are also discussed
