摘要

Discontinuity orientation is an important factor that controls mechanical behavior of rock masses and need to be obtained and studied in modern rock mass engineering. Digital close range photogrammetry (DCRP) is applied to orientation measurement because of its non-contacting object feature. Rock high slope was used as research object. Discontinuity orientation was obtained by using DCRE Orientation precision based on error theory was studied under different image processing methods, photograph distances, camera resolutions and control point distributions. The study shows that compared with compass measuring data, orientation obtained with DCRP fundamentally meets the requirement (the firing RMS error below 6°) on the condition of 8 or more control points (precision 0.01 m) surrounding the object and approximate straightness photography of photography distance 70m, photography baseline 10m, baseline direction paralleling to the slope strike and using digital camera (8M oixels).
