Four-dimensional visualizations method of cultural heritage

Abstract

The invention provides a four-dimensional visualizations method of a cultural heritage. The method comprises the following steps of determining a reason of a cultural heritage surface color change; acquiring a rule of the surface color change along with time, which includes of simulating a corresponding cultural relic surface color change process in a laboratory, establishing a quantification relation of corresponding time and a sample chromatic value so as to establish a function relation of a sample color and time, and acquiring a time model of the color change; acquiring a cultural-relic digital three-dimensional model; carrying out texture image acquisition and uniform color brightness balance processing, which includes of using a camera to acquire an image of the cultural relic at a current time period and taking as a texture image of a later colorful three-dimensional model; using texture mapping to generate the colorful three-dimensional model; and adding a time dimension to generate a cultural-relic four-dimensional model, which includes of setting a time axis to set time, calculating and generating a space-time texture of set time according to the time model of the color change, drawing a colorful three-dimensional model of the set time and forming a four-dimensional visualization effect through displaying the colorful three-dimensional model of a plurality of determined time points.

Description

technical field [0001] The invention relates to the technical field of digital protection of cultural heritage, in particular to a four-dimensional visualization method for high-precision digital reconstruction of cultural heritage and display of color changes and restoration effects of cultural heritage. Background technique [0002] The four-dimensional visualization of the entity is the simulated display of the entity in time and space, that is, 3D space + time. It can not only provide the observer with a spatially approximate real visual experience, but also show the change of the entity over time, which is convenient for observation The reader understands the entire change process of the entity, which provides a basis for learning and researching the attribute characteristics and change laws of the entity in time and space. The 3D model is a simplified expression of the real 3D world, and time is the axis of change of the 3D model and the dimension of change in the real...

AI Technical Summary

Problems solved by technology

4D reconstruction methods based on old data are dependent on the data itself, thus limiting their applicability

The method based on modeling analysis is prone to deviation of the results due to the deviation of the model
