Embodiment Construction
[0028] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0029] Such as figure 1 Shown is a schematic structural view of an embodiment of a machine vision inspection device based on a line scan camera.
[0030] The machine vision inspection device includes a driving roller 1, a first encoder 2 and a line scan camera 5, wherein the product to be detected is placed on the surface of the driving roller 1, the first encoder 2 is installed on the driving roller 1, and the driving roller The cylinder 1 drives the first encoder 2 to generate the first encoder pulse signal by rotating, the diameter of the driving roller 1 is d, and the resolution of the first encoder 2 is K 1 , the resolution of the image collected by the line scan camera 5 is λ, and the encoder resolution required to trigger the line scan camera 5 to collect images is K, When the pulse signal of the first encoder does not meet the resolution req...
