A method and device for fisheye camera automatic calibration is disclosed. A first straight line and a second straight line are respectively moved to generate a first fisheye line and a second fisheye line being straight lines. At least two symmetric points are generated on the second straight line based on an intersection of the first straight line and the second straight line as a symmetric central point, so as to correspondingly generate at least two fisheye symmetric points. The second straight line rotates until a distance between the first fisheye line and each of two fisheye symmetric points is equal. Then, central intersection coordinates, fisheye symmetric coordinates, a fisheye symmetric distance are retrieved and used to calculate fisheye parameters.
