Calibration Boards: Types and Importance in High-Precision System Calibration High-precision system calibration is the foundation of accurate measurement and inspection in machine vision systems. Calibration boards play a crucial role in this process. By collecting images in the machine vision system environment and collaborating with professional calibration algorithms, the high-precision calibration system performs error measurement and evaluation. It accurately determines the range of vision and error value at any position, which allows it to evaluate the accuracy level of the entire measurement system. The second step is the correction and compensation of the error image. The calibration system corrects and compensates each pixel information on the image according to the error data obtained in the first step. This process includes image translation, rotation, interpolation, reconstruction, brightness compensation, etc. The corrected and compensated image can more accurately reflect the actual situation of the object under test, achieving the purpose of precise measurement. Calibrated boards are used in machine vision systems, image measurement, photogrammetry, three-dimensional reconstruction, etc. They correct lens distortion, determine the conversion relationship between physical size and pixels, and establish the geometric model of the camera imaging. With the right fixed-pitch pattern array plate, the camera's shooting and the calculation of the calibration algorithm can obtain high-precision measurement and reconstruction results. Ningbo Zhixing Optical Technology Co., Ltd. is a technology-based enterprise focusing on the research and development of optical devices. With many professionals graduating from famous optoelectronic schools like Changchun Institute of Optics and Mechanics, Zhejiang University, Beijing Institute of Technology, etc., the company can complete optical system design, aspheric surface processing, aspheric inspection tool (computational hologram, CGH) production, machine vision calibration board development, and provide the best solutions based on customer needs. Furthermore, the company has independent intellectual property rights to aspheric inspection tools, breaking the monopoly of foreign counterparts in this technology. It has maintained long-term cooperation with many well-known enterprises at home and abroad in the development of calibration boards. With proper calibration boards, high-precision calibration systems achieve accurate measurement and inspection of machine vision systems, thus improving the accuracy of the entire measurement system.
