    • PROBLEM TO BE SOLVED: To provide a defect detection method for a flat panel light-related plate in low and high resolution images by using a computer vision technology and high speed image processing algorithm.
      SOLUTION: In this defect detection on the low resolution image, the image is smoothed by dividing it into blocks for correcting erroneous detection due to overall luminance change, and when the result of comparison of the image with a critical value shows deviation from the range, an abnormal pixel is determined. If at least two or more abnormal pixels are gathered, a speckle is determined. In defect detection on the high resolution image, the pattern is removed when the image includes a periodical pattern, and when the result of comparison of the image with the critical value shows deviation from the range, an abnormal pixel is determined. The adjacent abnormal pixels are grouped, and if the image of the adjacent pixels corresponds to a defect with a defect pixel number and below a predetermined luminance standard, it is processed as a point defect. If the grouped pixels correspond to a defect with the defect pixel number and above the predetermined luminance standard, it is processed as a foreign matter defect.

    • 要解决的问题:通过使用计算机视觉技术和高速图像处理算法来提供低分辨率图像中的平板灯相关板的缺陷检测方法。 解决方案:在低分辨率图像的缺陷检测中,通过将图像分割成用于校正由于整体亮度变化引起的错误检测的块来平滑图像,并且当图像与临界值的比较结果显示偏离 该范围,异常像素被确定。 如果聚集了至少两个以上的异常像素,则确定散斑。 在高分辨率图像的缺陷检测中,当图像包括周期性图案时,图案被去除,并且当图像与临界值的比较结果显示偏离该范围时,确定异常像素。 相邻的异常像素被分组,并且如果相邻像素的图像对应于具有缺陷像素数并且低于预定亮度标准的缺陷,则其被处理为点缺陷。 如果分组的像素对应于具有缺陷像素数并且高于预定亮度标准的缺陷,则其被处理为异物缺陷。 版权所有(C)2005,JPO&NCIPI

    • PURPOSE: An apparatus for inspecting defects is provided to remove unnecessary noise from inspection image of defects because a target image using the light of relevant wave length does not get influenced by light of other wave lengths. CONSTITUTION: An apparatus for inspecting defects comprises a first light source(110), a second light source(120), a first camera(130), a second camera(140), a dichroic mirror(150), and an image processing part(160). The first light source makes light of first wave length irradiate to a target object(10). The second light source irradiates light of second wave length shorter than the first wave length to the target object. The first camera gets image of the target object using the light reflected by the target object after irradiating from the first light source. The second camera gets image of the target object using the light reflected by the target object after irradiating from the second light source. The dichroic mirror gets the light reflected by the target object after irradiating the first or the second light source. The image processing part combines the images getting from the first and second cameras by arranging the images by turns.

    • The present invention comprises an inspection method for transparent or reflective inspection objects, by using a retroreflective plate as a convex lens or concave mirror in such a way that defects can be detected in a stable fashion even if the inspection object is curved or if vibration occurs during movement of the inspection object; in which displacement of parallel light passing through or reflected in a measurement field is captured by using changes which occur in an inspection field, namely changes in the density gradient in the case of transmission inspection or in the reflection angle in the case of reflection inspection. The present invention also comprises an inspection device for defect inspection, in which a knife edge is provided, horizontally to the optical axis, on the front surface of a camera lens for collecting the transmitted light or reflected light, in such a way that three-dimensional defect images can be obtained since any light which diverges from the parallel light is blocked with consequent changes in the contrast of the light due to the density gradient in the inspection field at the camera.
