Description

The present invention relates to a defect identification system for paintings, and more particularly to a defect identification system for paintings that automatically marks the position of a defect after acquiring a defect in the painting using a variable light source.

The causes of damage to paintings are very complex, including natural deterioration and human causes. Damage due to so-called natural deterioration means that the material or painting method selected by the painter does not conform to the creative technique of the painting and causes damage. That is, when the painting is completed, the fate of whether or not it is easy to preserve in the future is determined. Damage caused by human causes is complicated and various, such as unfavorable preservation environment, natural disasters, accidents at the time of exhibition, wrong conservation and restoration method, etc., and it is further destroyed by war, political and religious causes in Western history. All of these are also included in the causes of human damage. Such damage led to the damage and defects of the painting.

However, many of the defects that occur in the current painting creation process and conservation / restoration process are physical tests to detect defects in the painting, and the physical tests include two types of methods, visible and invisible. Visible tests include image illumination (cross-sectional light, sodium vapor, etc.), image enlargement (enlarged photography, close-up photography, micrograph photography, etc.), and invisible tests refer to ultraviolet radiation, infrared radiation, and X-rays, with the naked eye. Allows the study of invisible parts, and after detecting defective parts of the painting, marks and positions the relevant positions of the painting. However, since the position of the defect in the painting cannot be confirmed in the process of inspecting the defect in the painting and it cannot be marked directly on the painting, subsequent processing becomes difficult in such a process.
