Wide researches have been performed in the field of earth slope stability analysis by the use of limit equilibrium, strength reduction, and limit analysis methods. All the available methods present slope factor of safeties in a range with a little difference and confirm each other. It could be validated the analytical results by the help of instrumentation in actual slopes existing in the field. In addition, another approach that can be used for the validation of results is experimental modeling. In experimental simulation, it is required to manufacture the intended model in laboratory concerning the effect of reducing dimensions on the other parameters. In the present paper, it is attempted to investigate slope safety factor against sliding by simulating the slope in laboratory using of image processing system. The test container has dimensions of 1.5 × 1.5 × 2 m. The results have illustrated that when slope angle increased 13 degrees, the crest displacement in reinforced slope is 30 mm in the experimental modeling and 13 mm in numerical analysis. In the unreinforced slope, when the slope angle increased 8 degrees the slope failed and factor of safety in the numerical modeling became less than one.
