Embodiment Construction
[0028] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.
[0029] Objectively speaking, the color of the built environment is restricted by a specific geographical environment and a specific construction site, and the only common attribute is that the colors of all elements in the built environment are irradiated by sunlight during the day and present colors. For viewing by the human eye, the color in each visual interface is a spectral collection of fixed points of environmental elements, and the color changes when the light changes. Therefore, it is inaccurate to rely on the human eye to recognize and distinguish colors. In order to understand these objectively existing colors in essence, it is necessary to use the measurement theory of colorimetry, based on the fitting principle of the spectral curve, and use the spectrophotometric instrument to extract the spectral data of each environmental elemen...

The invention discloses a method for quantitatively describing an established environment color based on a three-element method, and belongs to the field of landscape gardening color analysis. The method comprises the following steps: extracting inherent chrominance data of a built environment element; converting chroma data into man-machine shared HSB color data including a hue value (H), a saturation value (S) and a brightness value (B), analyzing colors, color changes and color compositions of landscape composition elements in a built environment through digital quantitative description ofthe three color elements, and evaluating color comparison and organization of landscape color planning design. The method is applied to outdoor environment color analysis for the first time; through digital detection of inherent chromaticity of substances and digital conversion of three elements of colors, the purpose of quantitatively describing color composition of a built environment is achieved, objectivity, scientificity, effectiveness and controllability of color description are guaranteed in the conversion process, and the problem of metamerism generated when a designer describes and judges colors of landscape elements by means of visual perception is avoided.
Description
technical field [0001] The invention relates to the technical field of color analysis of buildings, cities, and landscape garden environments, in particular to a method for quantitatively describing the color of built environments based on the three-element method. Background technique [0002] Color is an objective phenomenon produced by light. It is a physical process in which matter absorbs and reflects light waves. Electromagnetic waves with different wavelengths determine the type of color perceived by the human eye. At the same time, color is also an objective perception process. Light waves stimulate the color-sensing cells of the human eye. Awareness about color types, composition, and effects is generated in the brain, and through the process of synaesthesia, cultural, emotional, and aesthetic subjective awareness is born. The so-called built environment refers to the artificial environment provided for human activities, including large urban environments. It is th...
