The invention comprises an interactive single image material acquiring system based on YUV color space and a method. According to the method, a single flat sample material image satisfying requirements is provided for the system; highlight separation of the material image is carried out to acquire a diffuse reflection graph and a mirror reflection graph of the highlight image; the diffuse reflection graph of the highlight image acquired by a separation module is acquired, interactive calculation is carried out based on brightness of the diffuse reflection graph to acquire a normal graph; the normal graph is acquired to calculate to acquire a diffuse reflection coefficient; brightness of the mirror reflection graph is taken as a highlight coefficient, and a final highlight coefficient and a mirror reflection coefficient are acquired through re-calculation based on the highlight coefficient and parameters set by a user. The method is advantaged in that an interactive operation mode is employed, a material chartlet generated based on the single image is utilized, and problems of long material making period, high cost and low precision existing in digital construction, game making and movie and television animation fields in the prior art are solved.
Description
technical field [0001] The invention relates to an interactive single image material acquisition system and method based on YUV color space, belonging to the field of computer graphics. Background technique [0002] Material acquisition methods and reconstruction in virtual scenes are important research topics in computer graphics. In the past ten years, researchers have proposed many processing methods and developed corresponding systems, for example, the BTF (Bidirectional Texture Function) acquisition system of Bonn University. However, this type of system has disadvantages such as complex system construction, long data acquisition time, large data volume, and long data compression time, so the material acquisition system has not yet entered the stage of practical application. [0003] In recent years, the use of a single image to obtain material appearance has attracted the attention of the industry and researchers, and a variety of material acquisition and editing syst...
