Optical calibration artifact
WebIdeally, the calibration must be made by the robot manufacturer, who has suitable installations involving high-accuracy measurement devices, such as an optical tracker, a laser tracker, or even a Coordinate Measuring Machine (CMM) . The main advantage of in-house calibration, however, is that the new mathematical model is embedded directly in ... WebFlat-field correction (FFC) is a technique used to improve quality in digital imaging. It cancels the effects of image artifacts caused by variations in the pixel-to-pixel sensitivity of the detector and by distortions in the optical path. It is a standard calibration procedure in everything from personal digital cameras to large telescopes.

WebDistortion is a monochromatic optical aberration describing how the magnification in an image changes across the field of view (FOV) at a fixed working distance (WD); this is critically important in precision machine vision and gauging applications. Distortion is different from parallax, which is the change in magnification (FOV) with WD (more ...
WebMay 6, 2024 · A CMM calibration artifact helps to ensure the precision and accuracy of the measurement data from a CMM. This assures reliable results and benchmarks such as safety, quality, and equipment lifespan. All CMM calibration artifacts adhere to the ISO 10360 series when performing calibration.
