Abstract
In an automatic camera calibration method in a system comprising a plurality of cameras, the automatic camera calibration method is characterized in that for each of the cameras, the estimated values of the position and posture of the camera are updated on the basis of observation information shared with the surrounding cameras and the estimated values of the respective current positions and postures of the surrounding cameras. An example of the observation information is the two-dimensional coordinate value of an image to be observed on an image plane of the camera and the size of the image to be observed.
