Zusammenfassung: | The invention relates to a method for automatic on-line detection of defects of a woven textile. According to the method for the automatic on-line detection of the defects of the woven textile, fabric collection is conducted by means of double cameras, grain extraction is carried out on the whole piece of fabric which is in the shooting area of the camera in the upstream firstly, whether the fabric is a qualified product is preliminarily detected, zonal secondary grain extraction is carried out on the fabric which is shot by the camera in the downstream if the fabric is unqualified, and detect recognition is carried out at the same time. According to the method for the automatic on-line detection of the defects of the woven textile, due to the fact that the same piece of fabric is shot by the two cameras at different positions, misjudgment caused by interference such as light reflection is avoided; due to the fact that the zonal secondary recognition is carried out after the preliminary recognition, the recog |
