360° Image Orientation Without Remapping

The patent applies preliminary action by computing the rotational angle in advance before the image is used. The rotational angle is calculated based on the position of a reference point (such as the point where the optical axis intersects the image plane) relative to the image center. This pre-computed rotational angle is then used to rotate the 360° image, establishing the correct orientation before the user needs to perceive directions. This resolves the contradiction by preparing the orientation information ahead of time, avoiding the need for complex real-time processing while ensuring proper direction perception.

The patent applies parameter changes by modifying the orientation parameter of the 360° image through rotation. Specifically, the image is rotated by a computed rotational angle to reposition the reference point to a designated orientation (such as the top center of the image). This parameter change (rotation angle) transforms the distorted 360° view into a properly oriented image that maintains its full-perimeter structure while enabling intuitive direction perception. This resolves the contradiction by changing the orientation parameter to achieve both structural preservation and ease of direction perception.

The patent applies the taking out principle by extracting the essential information needed for orientation from the 360° image itself. Specifically, the reference point (where the optical axis intersects the image plane) is identified within the image data, and the rotational angle is computed based solely on the positional relationship between this extracted reference point and the image center. This extraction approach resolves the contradiction by obtaining the necessary orientation information directly from the image content without requiring external sensors or complex processing systems, thus improving direction perception while keeping processing complexity manageable.

The patent applies self-service by enabling the 360° image to provide its own orientation information through internal analysis. The image itself contains the reference point that defines its orientation, and the system uses this self-contained information to compute the rotational angle and correct the direction perception. This self-service mechanism resolves the contradiction by eliminating the need for external orientation sensors or complex processing systems, as the image data itself suffices to determine and correct its orientation.

The patent applies the inversion principle by reversing the conventional approach. Instead of remapping the 360° image to a conventional perspective view (which loses the full-perimeter structure), the patent inverts the problem by keeping the 360° cylindrical structure intact and instead rotating the entire image to achieve proper orientation. This inversion resolves the contradiction by maintaining the original 360° view structure while still making the image usable through proper rotational orientation, thus preserving both the structural integrity and adaptability of the image.

The patent applies preliminary action by pre-computing the rotational angle based on the reference point position before any orientation correction is applied. This pre-computed angle is then used to rotate the 360° image, establishing the correct orientation while preserving the original cylindrical structure. This resolves the contradiction by preparing the orientation information in advance, allowing the 360° view structure to be maintained while achieving effective usability through proper orientation, thereby avoiding the need for distortion-removing remapping.
