Problems solved by technology

In common handheld or mobile shooting scenarios, the posture of the camera cannot be kept stable
Although due to the ultra-viewing angle feature of the panoramic camera, it will not lead to the lack of viewing content, but the change of the viewing angle will still cause a decline in user experience on the panoramic playback side.

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] The invention proposes a method for automatically stabilizing the shooting angle of view of a panoramic camera. Based on the data of the inclination measurement sensor, the global transformation and mapping algorithm is performed on the captured panoramic image, and the panoramic image is automatically corrected to an image with a vertical and upright perspective through software, so that it can still provide good viewing in the case of unstable shooting postures Panorama video or image with effects.

[0022] Hardware solution: On the basis of the hardware solution of ordinary panoramic cameras, the present invention needs to add an additional inclination measurement sensor. A common three-axis gyroscope is used to measure the angle between the camera axis and the gravity line, that is, the camera inclination. The rest of the hardware scheme is the same as that...

Abstract

The invention provides a method for automatically stabilizing a shooting view angle of a panoramic camera. Based on data of an inclination measurement sensor, a global transformation mapping algorithm is performed on a shot panoramic image, and the panoramic image is automatically corrected into an image with a vertical erected view angle in a software mode, so that panoramic video or images with a good viewing effect can still be provided under the condition that the shooting posture is instable.

Description

technical field [0001] The invention relates to the field of photographing and imaging, in particular to a method for automatically stabilizing the viewing angle of a panoramic camera. Background technique [0002] Due to its good on-the-spot experience and portability, panoramic cameras have been increasingly used in live video and picture sharing. In common handheld or mobile shooting scenarios, the posture of the camera cannot be kept stable when shooting. Although due to the ultra-viewing angle feature of the panoramic camera, the viewing content will not be lost, but the change of the viewing angle will still cause a decline in user experience on the panoramic playback side. Contents of the invention [0003] In order to solve the problems in the prior art, the present invention provides a method for automatically stabilizing the angle of view of a panoramic camera. When the overall camera group is tilted to a certain degree, the projection spherical surface actually...
