Abstract

In view of the fact that the source and target parts are contained in the reference target, the existing model expression is inconsistent with the actual cognition. A quantitative detail direction relationship expression model is proposed to establish a two-layer grid direction relationship matrix for spatial objects. The expression ability of the two-layer grid direction relation matrix is tested and analysed. Through the comparison and analysis with the calculation results of the direction relation binary in literature [7] and the grid direction relation matrix in literature [8], the recognition ability of the two-layer grid direction relation matrix to displacement and rotation is verified. Finally, it is proved that the method in this paper is effective in the calculation of spatial direction similarity, extended cartographic comprehensive evaluation, data matching and fusion applicability of work tasks such as change detection and update.
