  • In this paper, an error entropy model for spatial linear positional uncertainty is constructed from the point of information entropy in the paper. The model is composed of a cylinder and an error ball. The cylinder radius is the error entropy in the plane perpendicular to the spatial line. The model is certain. The theory and experimental results indicate that this model is effective.

Abstract: In this paper, an error entropy model for spatial linear positional uncertainty is constructed from the point of information entropy in the paper. The model is composed of a cylinder and an error ball. The cylinder radius is the error entropy in the plane perpendicular to the spatial line. The model is certain. The theory and experimental results indicate that this model is effective.
