New to visio, Calibration of camera??????

kornflakes
Hello.
I'm new to this forum and to the software too.
I would like to ask if someone knowes how to calibrate camera and illumination. Do I need something for calibration?
When I try to calibrate camera do I need a Hexagon block???
What is a Hexagon block?
We have a Tesa visio 300 machine and PC DMIS 4.2 and 4.3, but the probe is calibrated only in 4.3. When I work in 4.2 I don't have the calibration.
Is calibration procedure similar to one in other software? Until now I was using McCosmos. Are this softwares similar?
Help please!
Thank for your answers.
  • The software are not similar. Yes there is an optics calibration. I am not a Vision expert, call technical support and they can help you with this question.
  • I would think that you would have something to calibrate the optics like a glass scale for the different magnifications and probably a calibration sphere.
  • Thanks for your answer, but I don't find anything to calibrate except calibration sphere. Can I calibrate camera with calibration sphere? What abaut illumination?

    I was also wondering is on this forum someone from Slovenija, Croatia, Bosnia or Serbia?
  • I would contact whoever you bought that system from because you can calibrate the camera to the probe if you have that option but you should have some type of glass scale or glass magnification scale that lets you calibrate the optics and the zoom. As far as the illumination i would not think that it needs calibrated that is really just for you to be able to see the part which the lighting would change from part to part. I could be wrong on the lighting but to me that just does not make sense to calibrate that. I would look really hard though to find the scale for the magnification.
  • Lighting calibration is critical, especially for top lit features. The lamps tend to change in intensity over time.

    Make sure that it is done with any overhead lights (for the room) at the same setting that you will run the programs at.
  • To calibrate the optics you will require the Hexagon Glass Slide. This is usually not supplied with the TESA machines as the optics calibration is only done if something changes in the optics. This slide can be purchased from you local TESA agent

    The illumination calibration is required periodically as the lamps will change over time. For the top and ring light we recommend for general perpose you use just a focus on sheet of white paper. The bottom light is done by bringing the glass into focus.

    The Camera to Tactile Calibration is done on a ring gauge. This will usually be supplied as part of the qualification unit.
