Dot Vision Calibration Plate: High Precision & Stability

Dot Vision Calibration Plate High Precision Good Stability

Product Introduction The dot vision calibration plate is a plane calibration tool designed with regularly arranged circular marks (dots). These dots are known feature points and are used in image processing and computer vision to calibrate and verify the imaging performance of the camera, including lens distortion correction, focal length determination, image scaling calculation, etc. By taking an image of the calibration plate and using image processing algorithms to identify and locate the dots, the internal and external parameters of the camera can be calculated, thereby achieving accurate calibration of the camera.

Application Area Autonomous driving In the fields of driverless cars and drones, it is used for camera calibration and sensor calibration to improve the accuracy and safety of autonomous driving systems Machine vision In the fields of industrial automation, robot navigation, etc., it is used for camera calibration and distortion correction to improve the accuracy and stability of machine vision systems Photogrammetry In the fields of virtual reality and augmented reality, it is used for 3D 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 dots are precisely machined and measured to ensure their precise position and size on the plane Good Stability Made of stable materials, such as glass or ceramics, which are not easy to deform or wear Easy to Identify As feature points, the dots have high contrast and clarity, making them easy to identify and locate Flexibility Can be customized according to different application requirements, including the size, quantity, and arrangement of the dots
