PIPETTING SYSTEM AND CALIBRATION METHOD THEREOF

A pipetting system and a calibration method thereof are provided, which belong to the technical field of pipetting equipment, and are used to solve the calibration problem of the pipetting equipment. The method for calibrating a pipetting system includes: acquiring a first image of a calibration point by an image capturing device; obtaining a first offset of a center point of the image capturing device from a calibration point in the first image, and the image capturing device is calibrated according to the first offset; using the calibrated image capturing device to capture a second image of a tip of the pipette of the pipetting system and a third image after the tip is displaced; obtaining a second offset of a third image relative to the second image of the tip; obtaining a focus distance offset of a sharpness value of the third image relative to a preset sharpness value according to the displacement, a variation of the sharpness value of the third image relative to the second image, and a preset mapping ta
