Types of calibration boards
Material distinction |
advantage |
shortcoming |
ceramics |
The advantages of ceramic calibration plate are non-reflective and high contrast. |
Restricted by material, the maximum pattern is 200*200mm, the material is expensive, it is difficult to process with high precision, and the rejection rate is high. |
Glass |
The advantage of the glass calibration plate is that it can process high-precision 690*590mm patterns with high precision, the processing technology is much more mature than that of ceramics, and the price is cost-effective. |
Reflective and fragile. |
Calibration Target is used in machine vision, image measurement, photogrammetry, three-dimensional reconstruction and other applications to correct lens distortion; determine the conversion relationship between physical size and pixels; and determine the three-dimensional geometric position of a point on the surface of a space object and its location. The relationship between the corresponding points in the image requires the establishment of a geometric model of the camera imaging.
Chrome film exhibit
Through the camera's shooting of the fixed-spacing pattern array plate and the calculation of the calibration algorithm, the geometric model of the camera can be obtained, so as to obtain high-precision measurement and reconstruction results. The flat plate with a fixed-pitch pattern array is the calibration plate.
