The image includes information of at least a portion of a checkerboard displayed on the screen. The method further includes generating a calibration signal based at least in part on the attitude information, displaying the calibration signal on the checkerboard on the screen, and displaying a guiding signal on the screen. The guiding signal is configured to guide a user to move the imaging device or the screen.
