Embodiment Construction
[0018] In order to facilitate those of ordinary skill in the art to understand and implement the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and implementation examples. It should be understood that the implementation examples described here are only for illustration and explanation of the present invention, and are not intended to limit this invention.
[0019] The automatic coloring of the administrative division map needs to calculate the coloring area of the map and configure the color in the coloring area under the premise of a given color template set. The calculation of the map coloring area needs to take into account the area balance of each color block, and the spatial allocation of colors needs to take into account the laws of human visual perception, quantify the relevant visual perception factors, and establish a corresponding evaluation model to realize the allocation of colors i...

The invention discloses a map color effect optimizing method for administrative map coloring automatically. Firstly, a color matching area is obtained through calculation by using a backtracking method with area equalization constraint, secondly, visual perception factors needing to be considered in the process of administrative map color configuration are quantized, wherein the visual perceptionfactors comprise color coordination, color contrast and visual balance, and a corresponding map coloring effect evaluation model is established. Under the premise of a given color template set, the optimization of an administrative map color configuration scheme is achieved. The map color effect optimizing method for administrative map coloring automatically takes full account of a map color visual rule in the administrative map color configuration to assist in achieving the fast color configuration of the administrative map and meet charting requirements.
Description
technical field [0001] The invention belongs to the technical field of map design, relates to a method for designing and configuring map colors, and more particularly relates to a method for optimizing map color effects for automatic coloring of administrative division maps. Background technique [0002] Color is an important map language, and its role in map design cannot be ignored. The administrative areas on the administrative division map need to be distinguished by color, and the color of these large-scale maps often determines the color style of a map. Therefore, the color configuration of the administrative division map needs special attention. [0003] Scholars at home and abroad are currently mainly studying the "four-color coloring" problem of administrative division maps, emphasizing that "the colors of adjacent color blocks on administrative division maps are not the same". The commonly used coloring area calculation method only finds a solution that satisfies...
