Problems solved by technology
There are two important problems. One is that the collection information is not comprehensive, and only color information can be collected.
The second is that the quality is unstable, and it cannot be widely used in the collection of visual information of various materials.
However, there are very serious errors in the conversion results, which are difficult to use for high-quality material applications
Moreover, the converted data types cannot be standardized and unified, and it is difficult to meet industrial application standards

The invention relates to a multi-channel-based digital collection method of material surface visual information, which belongs to the field of optical technology. It can process color, normal line, highlight and transparency channel according to multi-directional image information, generate corresponding color information, normal line information, highlight information and transparency information, and further generate material surface visual information of the object to be photographed. In this way, the material surface visual information such as color, normal, highlight, and transparency can be obtained simply, accurately, and quickly at one time. The information range is wider, the efficiency is higher, and the implementation method is simple, and the application cost is based on multi-channel material surface vision. Information digital collection method.
Description
technical field [0001] The invention relates to the field of optical technology, in particular to the field of optical imaging technology related to industrial visualization, and specifically refers to a multi-channel-based digital collection method for material surface visual information. Background technique [0002] Material surface visual information is widely used, mainly in industrial visualization material production, virtual reality material production, industrial, clothing, furniture, decoration and other digital material production, game material production, film and television material production, CG material production, etc. [0003] Most of the existing material visual scanning schemes are based on two acquisition modes, scanner or camera. There are two important problems. One is that the collection information is not comprehensive, and only color information can be collected. The second is that the quality is unstable, and it cannot be widely used in the colle...
