Abstract: The invention in this application is an information acquisition/identification system provided with an image-feature storing unit, an extracting unit, an acquiring unit, and an identifying unit. The image-feature storing unit stores image features of texture patterns formed on components or products. The extracting unit extracts an information-label image and a texture-pattern image from a taken image containing at least the following: an information label that displays information regarding a component, a product, or a product comprising said component; and a texture pattern formed on said component or product. The acquiring unit acquires, from the extracted information-label image, the aforementioned information regarding the component or product. The identifying unit identifies the component, product, or component-comprising product by matching image features of the extracted texture-pattern image against the image features stored by the image-feature storing unit.

Abstract translation: 本申请的发明是设置有图像特征存储单元，提取单元，获取单元和识别单元的信息获取/识别系统。 图像特征存储单元存储在组件或产品上形成的纹理图案的图像特征。 提取单元从至少包含以下内容的拍摄图像中提取信息标签图像和纹理图案图像：显示关于组件，产品或包括所述组件的产品的信息的信息标签; 以及形成在所述部件或产品上的纹理图案。 获取单元从提取的信息标签图像获取关于组件或产品的上述信息。 识别单元通过将所提取的纹理图案图像的图像特征与由图像特征存储单元存储的图像特征相匹配来识别组件，产品或包括组件的产品。
