Portal in the present invention is laid in the horizontal direction along the outer surface of the rubbing roll in the protrusion allows the width of the rubbing cloth portal at relates to a rubbing cloth inspection method for inspecting the aggregation and nuim, and more specifically to a rubbing cloth gwonpo the rubbing roll the present invention relates to an inspection method for inspecting presence.
Rubbing cloth inspection method for inspecting the aggregation and nuim of the present invention, the rubbing carriage installation located on the rotating portion, and a side surface of the rubbing roll to chukseol rotatably the gwonpo the rubbing roll to be taken of the rubbing roll surface and the tangential direction, respectively a first and a camera and a second camera, the first camera and the second and the front portion illuminant and the back part illuminant for irradiating light to the second camera, the subject, the first camera and for analyzing the received input a second camera shooting video of the in the rubbing cloth inspection method using the inspection apparatus including a control unit, in view of the rubbing roll rotatably coupled to the rotary part, and places the first camera to photograph the surface of the rubbing roll, the first camera and the rubbing roll within the allowable range of the projected first camera by placing the front light emitting part to irradiate the image sensing surface while the first rubbing roll concentration irradiation of light to the rubbing cloth of the subject outer surface of the camera between Step of shooting the portal image to obtain a portal image forming direction of the rubbing cloth being bonded to the coordinates of the rubbing roll and; Placing the second camera in a tangential direction of the outer circumferential surface rubbing roll and, combined with the coordinates of the second camera to place the rear section light emitting body to illuminate the subject with, while the light irradiation to occur taking a tangential image of the rubbing roll rubbing roll of step portal projecting length of the rubbing cloth to obtain an image; Analysis step of analyzing each of the portal formed by the portal imaging direction protruding length image control apparatus receives an input to determine whether or not more than the portal and; If the two in case the image analysis information determined by more than the portal image forming direction is, the portal projection length in the image determined in the determination step of determining a normal nuim nuim; comprises a.
In the analysis step determines the least area by measuring the intensity area of ​​a car or more permitted area intensity in the direction portal formed image generating, and the analysis step Next, it is determined as more than the area in the analysis information of the direction images portal forming, portal When the projection length in the image determined to be normal aggregation determining step of determining a bunching; there may be more.
