Data for camera intrinsic and distortion calibration

Checkerboard

Place the checkerboard in the field of view of the camera and make sure the checkerboard is in the camera's focus. Move the checkerboard or the camera to different positions and take images so that the coverage of the checkerboard in the camera's field of view is as high as possible. While moving the checkerboard or camera, it is necessary that the entire checkerboard is present in the camera's field of view. In addition, the checkerboard should be tilted slightly in different directions for each image. Do not move the board or the camera while taking the images. Also, do not hold the checkerboard by hand to minimize blur due to shaking. You can also use a computer monitor instead of a physical checkerboard for intrinsic calibration. Monitors are very accurate and flat. You can show this PDF file on the monitor for calibration.

Charucoboard

Place the charucoboard in the field of view of the camera and make sure the charucoboard is in the camera's focus. Move the charucoboard or the camera to different positions and take images so that the coverage of the charucoboard in the camera's field of view is as high as possible. While moving the charucoboard or camera, it is not necessary that the entire charucoboard is present in the camera's field of view. In addition, the charucoboard should be tilted slightly in different directions for each image. Do not move the board or the camera while taking the images. Also, do not hold the charucoboard by hand to minimize blur due to shaking. You can also use a computer monitor instead of a physical charucoboard for intrinsic calibration. Monitors are very accurate and flat. Please visit our website to download charucoboard https://calibrate.deepen.ai/target-generator
