The optical structure comprises a camera module, a bottom cover and at least four light sources, the light sources irradiate downwards and correspond to four independent light path channels, the bottom cover is in the shape of an inverted quadrangular frustum pyramid and is hollow, an observation hole is formed in the bottom of the bottom cover, and the camera module is arranged in the observation hole. Reflecting mirrors are installed on the four inclined faces in the bottom cover, the reflecting mirrors can adjust collimated light in each light path channel to 45-degree incident light aiming at the observation hole, the camera module can penetrate through the observation hole to take a picture, and the technical characteristics that miniaturization and standardization of the light path environment can be achieved, and the incident angle of light rays is easy to control are achieved. 本实用新型公开的是一种用于织物沾色变色评级图片采集的光学结构，包括相机模组、底罩以及至少四个光源，所述光源往下照射且对应有四个独立的光路通道，所述底罩呈倒置的四棱台状且内部中空设置，所述底罩底部开设有观察孔，所述底罩内的四个斜面上安装有反射镜，所述反射
