How can the world coordinates of the camera be determined using a chessboard image?

edit

The world coordinates of the camera can be determined using a chessboard image by following these steps:

1. Take an image of a chessboard from different angles.
2. Use computer vision algorithms to detect the corners of the chessboard in each image.
3. Compute the position of the corners in the 3D world coordinates.
4. Use the multiple images to calculate the camera's extrinsic and intrinsic parameters.
5. Compute the transformation matrix that maps world coordinates to camera coordinates.
6. Use this matrix to determine the world coordinates of the camera.
