Dot Visual Calibration Board: Camera Calibration Essential

The circular dot visual calibration board is used to calibrate and verify the imaging performance of cameras

Product Introduction: The dot visual calibration board is a flat calibration tool designed with regularly arranged circular markers (dots). These dots, as known feature points, are used in image processing and computer vision to calibrate and verify the imaging performance of cameras, including lens distortion correction, focal length determination, image scaling calculation, etc. By capturing images of the calibration board and using image processing algorithms to identify and locate the dots, the internal and external parameters of the camera can be calculated, thereby achieving precise calibration of the camera.

Application field: machine vision: in industrial automation, robot navigation and other fields, it is used for camera calibration and distortion correction to improve the accuracy and stability of the machine vision system Automatic driving: in driverless cars, unmanned aerial vehicles and other fields, it is used for camera calibration and sensor calibration to improve the accuracy and security of the auto drive system Photogrammetry: in virtual reality, augmented reality and other fields, it is used for three-dimensional reconstruction and scene reconstruction to determine the internal and external parameters of the camera Biomedical imaging: in the biomedical field, it is used to correct the parameters of microscopes or imaging systems to improve the clarity and accuracy of images

Product features: High precision: The circular dots are precisely machined and measured to ensure their precise position and dimensional stability on a plane. They are made of stable materials, such as glass or ceramics, which are not easily deformed or worn and are easy to identify. The circular dots serve as feature points, with high contrast and clarity, making them easy to identify and locate. Flexibility: They can be customized according to different application needs, including the size, quantity, and arrangement of the circular dots
