Embodiment Construction
[0023] The present invention will be described below in conjunction with the accompanying drawings and examples.
[0024] Such as figure 1 As shown, the main structures required by the visual inspection system of the ring inner wall structure provided by the present invention are a camera 1 and a conical mirror 3, through which relevant information such as structures 4, 5 and 6 on the inner wall 2 of the ring body can be detected. Detection principle such as figure 2 As shown, first, the inner wall 2 of the ring is imaged as 9 by the conical mirror. By rationally designing the conical mirror, 9 can be located on the same plane as possible and facing the camera. Subsequently, the image 9 is captured by the camera 1 composed of the image sensor 11 and the lens 12 to obtain the image 10 . Such as figure 2 As shown in the figure, the ring body structure with a keyway on the inner wall is placed on the transparent plate 13, and the highest point of the conical mirror is lower...
