Ancient-fresco disease visual-analysis method based on MR glasses

Abstract

The invention relates to an ancient-fresco disease visual-analysis method based on MR glasses. The method includes: establishing a fresco disease and environment database, wherein the database includes disease deterioration records and environment monitoring data of a relic site; reading the disease deterioration records and the environment data in a certain distance according to a location wherea user is located, and respectively generating a disease view and a sensor view; traversing the fresco disease and environment database according to an alarm type condition set T input by the user, and extracting disease deterioration alarms, wherein each alarm includes occurrence time of the alarm and a disease detection area and an alarm type to which the same belongs; and adding alarm markers of different colors above a time axis of the disease view and the sensor view, carrying out line connection on markers belonging to the same alarm, and thus showing the time and space distribution of the disease deterioration alarms.

Description

technical field [0001] The invention relates to an on-site analysis method for diseases of ancient murals realized by using MR (mixed reality) glasses and interactive visual analysis technology, in particular to a visual analysis method for analyzing the correlation between mural diseases and the environment in combination with real objects. Background technique [0002] Mural paintings are the treasures of human cultural heritage, but ancient mural paintings around the world are generally suffering from various deterioration phenomena. These degradation phenomena are affected by environmental conditions and human factors, and are the comprehensive results of multiple effects such as physics, chemistry, biology, and geology. According to their symptoms, they can be classified into more than ten kinds of mural diseases [1]. There are many types of mural diseases, complex mechanisms, and continuous erosion of murals. Some types of diseases can cause irreparable damage to mural...

Problems solved by technology

[0005] At present, the visualization designed for on-site use can be divided into three categories according to the display and interaction methods: 1. Flat display, install multiple displays or projection devices to display images, move the screen, switch projection display to achieve a more flexible display effect, such as [3 ,4], but the site needs to be rebuilt, and the interaction mainly depends on key operations; 2. Video perspective, which synthesizes virtual objects into real-time captured images, displays and controls them through mobile devices such as tablets and mobile phones, such as [5], cost Low cost and flexible to use, but the effect of combining with the scene is limited; 3. Optical perspective, calculate the image of the virtual world that the user can see from the perspective, and display it on the transparent screen of the smart glasses lens. Most of the interactions use gesture voice and other more natural methods Ways such as [6], this type of flexibility is very good, the visual effect is more natural than the first two, but the technical threshold is relatively high, and there are few relevant results so far
