    • In the invention sparking in the object is monitored with a camera (201) and an image processing unit (203). The object is imaged and from the images thus obtained an image pair is formed in the image processing unit, in which image pair there is a first and a second image. Images of the image pair are compared to each other and those pixels that have values that are substantially the same in the corresponding pixels of both images and those pixels that have a value lower than the set threshold value are removed from the first image. The number of pixels remaining gives the sparking value that represents the sparking of the object. To compare the pixels of the image pairs there is a comparator (204) of pixels values in the image processing unit. The pixels that do not fulfil the comparison values are removed with the image reducer (205) from the first image. The number of pixels remaining in the first image is determined with the counter (206), which number is the sparking value, which is proportionate to the sparking occurring in the object at the time when the image was taken. The sparking value is delivered to the system (210) monitoring the object, which system undertakes the necessary actions if sparking exceeding a certain limit is detected in the object.
    • 在本发明中,用照相机(201)和图像处理单元(203)监视物体中的火花。 对象被成像并且从如此获得的图像中在图像处理单元中形成图像对,其中图像对存在第一图像和第二图像。 将图像对的图像彼此进行比较,并且从第一图像中去除在两个图像的对应像素中具有基本上相同的值的像素以及具有低于设定的阈值的值的那些像素。 剩余像素的数量给出表示对象点火的火花值。 为了比较图像对的像素,在图像处理单元中存在像素值的比较器(204)。 利用图像缩小器(205)从第一图像中去除不满足比较值的像素。 利用计数器(206)确定第一图像中剩余的像素的数量,该数量是火花值,该火花值与拍摄图像时在物体中发生的火花成比例。 火花值被传送到监视物体的系统(210),如果在物体中检测到超过特定极限的火花,该系统执行必要的动作。

    • The invention relates to a device for correcting radial run-outs during the fabrication of cylindrical parts (9). The device comprises a rotating spindle (4) which can be driven and a chuck (5, 6) which is fastened to the spindle (4) and accommodates a cylindrical part (9). The invention is characterized in that the chuck (5, 6) can be transversally displaced on the spindle (4) relative to the spindle axis (3) by being actuated with a defined force. In addition, a measuring device (12) is provided in order to determine a radial run-out of the cylindrical part (9) relative to the spindle axis (3). The invention is also characterized in that a final control element (14) can be controlled according to the measurement result of the measuring device (12) in order to generate the defined force which thus displaces the chuck (5, 6) relative to the spindle (4). The device permits the middle axis (13) of a cylindrical part (9) to be centered opposite the spindle axis (3) in a fully automatic manner.
