Water-land three-dimensional model joint color transition method based on face primitive poisson fusion

Abstract

The application provides a water-land three-dimensional model joint color transition method based on a face element Poisson fusion, and relates to the field of data processing. In the method, after the geometric fusion of the water area and the land area three-dimensional model, a water area pseudo-color texture is constructed based on water depth information, and a land area real image texture is obtained; a water-land boundary line is extracted through unified topological analysis; a face element buffer zone is constructed around the boundary line; local color change constraints of the water area and the land area are introduced in the buffer zone respectively, and a guide gradient field is constructed; then, a Poisson fusion model is established based on the topological relationship of the face element; the color of the face element is solved under the boundary color constraint; and the continuous transition and visually consistent fusion of the texture color of the water-land joint area are realized. The technical solution provided by the application facilitates the effective improvement of the color transition quality of the large-scale water-land joint area.
