【 摘 要 】

The paper presents an application of photogrammetric method to determine three-dimensional tyre-soil interface. Knowledge geometry of traces or ruts pressed by running wheels is important for terramechanical application, such as wheel-soil interaction analysis, soil compaction studies or wheel performance modelling. In this study we have aimed to reconstruct a 3D tyre-soil interface for an agricultural tractor running on soft, arable soil. Thee method utilizes simply photographing of wheel rut after a pass, possibly from different points of view. In order to enhance the analysis of the photographs, small markers have been applied to the wheel rut. Stages of image analysis have been presented in the paper. Final result, a complete reconstruction of tyre-soil interface with dimensioning has been included. It was concluded the method is simple yet precise and reliable for various practical applications.
