Measuring instrument, image, common _ ten common problems of image measuring instrument

The fluid solenoid valve tells about ten common problems of image measuring instruments. 　　 1. If you think the image window is too small, you can add a monitor, but you can't change the imaging range, and the imaging range is related to the magnification of the lens. Under the same lens conditions, it is also affected by the size of the CCD chip.　　2. Some people think that the photographic area of u200bu200bthe image measuring instrument is too small, which has no practical meaning. If you want to take a picture, you will take a picture of the entire workpiece. This is a one-sided view. Because we are using the phase overlay technology, each photo occupies a large amount of computer memory, and the processing speed will slow down. The main purpose of taking pictures is to reflect the local characteristics of the workpiece, or the field of view range of the lens can be appropriately changed. Increase the shooting area. At present, the image magnification of the lens used is between 28 times and 180 times, and the image area indicates that the size of the object is between 9mm×7mm and 1.4mm×1.1mm.　　 3. The difference between optical magnification and image magnification is: optical magnification refers to the magnification of the object through the eyepiece by the CCD. Image magnification refers to the actual magnification of the image and the object. The difference between them lies in the different magnification methods. The former achieves magnification through the structure of an optical lens without distortion. The latter is to increase the area of u200bu200beach pixel in the image through the processor in the CCD, so as to achieve the purpose of magnification, which only belongs to the category of image magnification processing.　　4. The movement direction of the image window and the worktable is opposite, and the CCD can be installed 180 degrees inversely.　　5. Why is the ellipse or two straight lines displayed when the circle is automatically captured (measured)? The possible reasons are as follows: the X, Y axis optical scale reading and the reading direction may be wrong; the compensation file may have a problem; the reading card may be abnormal; the linear calibration is wrong.　　 6. Geometry and image window are opposite? The reason may be: the parameter setting of the reading card is incorrect. Check whether the reading of each axis is consistent with the moving direction. If it is opposite, please adjust the corresponding parameters.　　7. The image window is blue. The reasons may be: the image cable may not be plugged in; the CCD may not be powered; the control box power may not be turned on, etc.　　 8. Why is the data obtained by the deburring measurement tool and the automatic measurement tool different? 　　 Answer: The point found by the automatic measurement is the edge point of the black and white boundary. While the deburring function scans the contour points, the working principle is different. Even if the data is bad, it should not exceed the specified error range.　　9. Can an image measuring instrument measure flatness? 　　Answer: Image measurement alone cannot measure flatness. If a probe or laser probe is added to a composite type measuring instrument, it can measure flatness.　　10. In the image window, what are the benefits of marking the size of the part image? 　　Answer: In this window, taking pictures after marking can give customers the most direct reference.
