Abstract:
The present invention is applied to the field of image processing, and provides a horizontal calibration method and system for a panoramic image or video, and a portable terminal. The method comprises: receiving images or video frames of two circles after being imaged by two cameras having opposite photographing directions; obtaining a horizontal calibration matrix during photographing; and pasting, according to the horizontal calibration matrix, the images or video frames of the two circles to a left hemispherical curved surface and a right hemispherical curved surface of a spherical panoramic mathematical model in aUVmapping manner, respectively so that the panoramic images or video frames pasted in the spherical panoramic mathematical model are horizontal. According to the present invention, when an image or a video frame photographed by a panoramic camera is not horizontal, the panoramic image or the video frame pasted in a spherical panoramic mathematical model is still horizontal.
