OpenCV 10mm Ceramic Calibration Board

You can rest assured of buying Zhixing OpenCV 10mm Ceramic Calibration Board from our factory. Our core research and development team includes a number of doctors who graduated from famous domestic optoelectronic schools.In terms of calibration plates, Zhixing can provide comprehensive and professional services in material processing, coating, semiconductor processing, precision cutting, and reliability testing.

OpenCV 10mm Ceramic Calibration Board produced by China Zhixing has high precision. Since the arrangement of marks in the calibration plate is certain, the internal matrix and distortion coefficient of the camera can be calculated by using the pictures taken by the camera, which can be used to calculate the actual physical coordinates under the camera coordinates to meet the accuracy requirements.

The OpenCV 10mm Ceramic Calibration Board is a tool for camera calibration, which is widely used in computer vision and machine vision. This machine vision calibration board is composed of many black squares and white squares alternately, which has certain specifications and industrial design advantages.

Secondly, it has high applicability. Because the black and white squares in the OpenCV 10mm Ceramic Calibration Board have obvious contrast, and the regularity and stability of the distribution of mark points can adapt to a variety of camera shooting conditions, and can process a large number of shooting data through simple calculation.

Physical display of ceramics square calibration plate

The OpenCV 10mm Ceramic Calibration Board is actually a geometric model with a fixed-pitch pattern array. The camera captures an image through a flat plate with a fixed-pitch pattern array (that is, the calibration plate), and then calculates the geometric model of the captured image through the calculation of the calibration algorithm. Then high-precision measurement and reconstruction results are obtained, lens distortion is effectively corrected, and the accuracy of image measurement and photogrammetry in machine vision applications is greatly improved.

In applications such as machine vision, image measurement, photogrammetry, and 3D reconstruction, the calibration board is mainly used to correct lens distortion; determine the conversion relationship between physical size and pixels; and determine the 3D geometric position of a point on the surface of a space object and the corresponding point in the image relationship to establish the geometric model of camera imaging.

OpenCV 10mm Ceramic Calibration Board 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. 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.
