Rockfall is a frequent and serious geological hazard in mountainous areas worldwide. It is of great significance to fully understand rockfall movement for disaster assessment and prevention. In this paper, based on the principle of binocular stereo vision, a filed experimental monitoring technology was developed to conduct the rockfall movement experiment research. Through the orthogonal experimental method, taking the block velocities obtained by binocular stereo vision system as a reference index, the impact factors such as the slope angles and the falling heights, shapes and masses of blocks on rockfall movement are studied. The lateral deviations and jumping heights of different blocks when they are released from the same falling height and moving along the same slope are presented. The results show that slope angle is the most key factor affecting block movement, while the falling heights, shapes and masses of blocks are the secondary factors. Moreover, the experimental methods and results of this paper can lay a foundation for the further study of rockfall movement characteristics.
