WebApr 27, 2024 · Before you can make precise measurements with a measuring eyepiece or a microscope camera, you must first calibrate each device with a standard called an object micrometer. This calibration establishes the micrometer value, which indicates how large the distance is between two graduations of the micrometer on your specimen. Geometric camera calibration, also referred to as camera resectioning, estimates the parameters of a lens and image sensor of an image or video camera. You can use these parameters to correct for lens distortion, measure the size of an object in world units, or determine the location of the camera in the scene.
