Abstract

In real-time measurement process of shield machine´s Guiding system, Horizontal angle measurement has always been a problem for attitude. In order to achieve the level of real-time measurement of the angle, I designed a self-contained laser target based on convex lens´ focusing characteristics. Using laser and industrial camera I realized the measurement of angular by image processing method. Experimental data show that the measuring angle can range ±5 degrees, accuracy can reach 1 mrad. The results can satisfy the demands of underground tunnel construction.
