Abstract At present, commonly used measurement methods for landslide model pay much attention to the measurement of global displacement without a detailed description of individual components. However, the multi-attitude data concerning the model of bedding rock slope lay the data foundation for describing the mechanism of landslide. In an attempt to obtain the 3D multi-attitude displacement data, this paper, based on the binocular stereo vision as the measurement tool, adopts the cyclic coded targets to follow the unique track of rock block trajectory. Furthermore, a combination of circular coded targets and assisted location marks is designed to obtain the spatial displacement and rotation angle of rock mass center implicitly through the local coordinate system. Finally, the data such as speed, accelerated speed are acquired in accordance with the relationship of time domain and spatial domain. The experiment results show that this paper provides an effective method for the collection of elaborate and accurate landslide data of the bedding rock slope model.

1 Introduction China is one of the countries with the most serious landslide disasters in the world. Every year, the collapse and landslide cause great losses to the lives and property of the people and state. Based on the detailed investigation of geological hazards, it has been found that the bedding rock slope occupies a considerable proportion in the slope of Qinba Mountains in southern Shaanxi Province. The landslides, derived from the jointed bedding rock slopes, exerts great influence on the production and life of local

people and units, and poses a serious threat to the local transportation trunk line, factory construction, residential location and power hub [1, 2]. In essence, the exploration of failure process and mechanism of this kind of slope plays an important role in the decision-making of landslide prevention and control, early warning and prediction of landslide, selection and design of comprehensive treatment scheme, safety guarantee of comprehensive treatment and construction [3–5]. However, in order to achieve the goals above, it is necessary to acquire the multi-attitude data of displacement, rotation angle, speed vector, accelerated speed vector, etc. in the landslide process. The landslide model experiment can better investigate some complex natural phenomena and intuitively reflect the essence of such phenomena, which provi
