Camera calibration technology is a crucial component in the imaging field that demands accurate camera intrinsic and extrinsic parameters as input for reconstruction algorithms. One of the most prevalent solutions is the Tsai algorithm, which was proposed in 1987. This method utilizes a non-coplanar dedicated algorithm to identify a 3D calibration object that provides a correspondence between image points and their 3D space counterparts. The calibration parameters are then computed using this correspondence. Adopting the Tsai algorithm can significantly improve the accuracy and reliability of camera calibration, making it a popular choice for various industries.

Precision measurement and inspection using machine vision systems requires high-precision calibration, which is the foundation and prerequisite for accurate results. This is because lens distortion is an inevitable factor in accurate measurement, and errors in images lead to inaccurate results, even with high-quality software.
Fortunately, modern calibration technology enables the correction and compensation of image errors to achieve a more realistic and accurate representation of the object under test. Zhixing Optics is a technology-based enterprise that specializes in the research and development of optical devices, such as computational holograms, aspheric surface processing, and machine vision calibration boards.
Their professional image calibration board captures high-resolution images that can be used to measure and evaluate error values at any position. These error values are then used to correct and compensate each pixel on the image. Subsequently, image translation, rotation, interpolation, reconstruction, brightness compensation, and other precise image algorithms are applied to create a more accurate representation of the object.
Ningbo Zhixing Optical Technology Co., Ltd. has a core R&D team with Ph.D. graduates from some of the most prestigious optoelectronic schools in China, such as Changchun Institute of Optics and Mechanics, Zhejiang University, and Beijing Institute of Technology. The team can complete optical system design, aspheric surface processing, and aspheric inspection tool (computational hologram, CGH) production.
In addition, the company maintains long-term cooperation with many well-known enterprises at home and abroad to develop calibration boards. This comprehensive and professional approach involves material processing, coating, semiconductor processing, precision cutting, and reliability testing.
