Abstract

The invention discloses a color code adjustment method based on RGB-IHS multi-attribute fusion. The method comprises the following steps: extracting three attributes to carry out RGB conversion; changing a color code space axis according to a preliminary fusion result to achieve a preliminary effect; coarsening adjustment is carried out on the attributes, wherein each attribute is clustered into at most two 256 colors; picking up the boundary of the dessert attribute; and realizing multi-directional integrated adjustment of the contrast saturation brightness confidence. The objective of the invention is to solve the technical problems of low regularity and high color code adjustment difficulty in seismic attribute RGB-IHS transformation in the prior art.

Description

technical field [0001] The invention relates to the technical field of oil and gas exploration, in particular to a color scale adjustment method based on RGB-IHS multi-attribute fusion. Background technique [0002] Seismic attributes have always been the most common and relatively reliable method in the field of reservoir prediction. In recent years, a multi-attribute fusion method based on RGB-IHS transformation has been developed. The main principle is to standardize the space of three different attributes. Reconstruction of pixel codes, and then mapped to IHS space for fusion to generate new images; compared with traditional imaging methods, the color resolution of seismic images is increased from 256 colors to 16 million colors, which can highlight subtle differences in seismic waveforms and greatly improve Reservoir imaging accuracy. But at the same time, due to the rich colors, the fused attributes also appear blurred when indicating the lateral changes of the reserv...
