Abstract
Systems and methods for capturing and transforming wide-angle video information are disclosed. Exemplary implementations may: guide light to an image sensor by a fisheye lens; capture wide-angled video information having a horizontal angle-of-view of 200 degrees or more and a vertical angle-of-view of 180 degrees or more; select a portion of the captured wide-angled video information; transform the selected portion into a rectilinear projection that represents the video sequence; and transform the rectilinear projection into a viewable video sequence that has a format suitable for playback in a virtual reality headset.
Claims21
A system configured for capturing and transforming wide-angle video information, the system comprising:
- a fisheye lens configured to guide light to an image sensor;
- the image sensor configured to capture wide-angled video information having a horizontal angle-of-view of 200 degrees or more and a vertical angle-of-view of 180 degrees or more, wherein the wide-angled video information is based on light that becomes incident on the image sensor, wherein the wide-angled video information represents a video sequence;
- one or more hardware processors configured by machine-readable instructions to:
- select a portion of the captured wide-angled video information, wherein the selected portion has a horizontal angle-of-view between 200 degrees and 250 degrees, wherein the selected portion has a vertical angle-of-view of 180 degrees or more, and wherein the vertical angle-of-view of the selected portion has fewer degrees than the horizontal angle-of-view of the selected portion;
- transform the selected portion into a rectilinear projection that represents the video sequence, wherein the rectilinear projection has a horizontal angle-of-view between 200 degrees and 250 degrees, wherein the rectilinear projection has a vertical angle-of-view of 180 degrees or more, and wherein the vertical angle-of-view of the rectilinear projection has fewer degrees than the horizontal angle-of-view of the rectilinear projection;
- transform the rectilinear projection into a viewable video sequence that has a format suitable for playback in a virtual reality headset;
- and
- store the viewable video sequence in electronic storage.

A method for capturing and transforming wide-angle video information, the method comprising:
- guiding light to an image sensor by a fisheye lens;
- capturing, by the image sensor, wide-angled video information having a horizontal angle-of-view of 200 degrees or more, wherein the wide-angled video information is based on light that becomes incident on the image sensor, and wherein the wide-angled video information represents a video sequence;
- selecting a portion of the captured wide-angled video information, wherein the selected portion has a horizontal angle-of-view between 200 degrees and 250 degrees, and wherein the selected portion has a vertical angle-of-view of fewer degrees than the horizontal angle-of-view of the selected portion;
- transforming the selected portion into a rectilinear projection that represents the video sequence, wherein the rectilinear projection has a horizontal angle-of-view between 200 degrees and 250 degrees, and wherein the rectilinear projection has a vertical angle-of-view of fewer degrees than the horizontal angle-of-view of the rectilinear projection;
- transforming the rectilinear projection into a viewable video sequence that has a format suitable for playback in a virtual reality headset;
- and
- storing the viewable video sequence in electronic storage;
- wherein the vertical angle-of-view of the selected portion is at least 180 degrees but fewer degrees than the horizontal angle-of-view of the selected portion.

A method for capturing and transforming wide-angle video information, the method comprising:
- guiding light to an image sensor by a fisheye lens;
- capturing, by the image sensor, wide-angled video information having a horizontal angle-of-view of 200 degrees or more, wherein the wide-angled video information is based on light that becomes incident on the image sensor, and wherein the wide-angled video information represents a video sequence;
- selecting a portion of the captured wide-angled video information, wherein the selected portion has a horizontal angle-of-view between 200 degrees and 250 degrees, and wherein the selected portion has a vertical angle-of-view of fewer degrees than the horizontal angle-of-view of the selected portion;
- transforming the selected portion into a rectilinear projection that represents the video sequence, wherein the rectilinear projection has a horizontal angle-of-view between 200 degrees and 250 degrees, and wherein the rectilinear projection has a vertical angle-of-view of fewer degrees than the horizontal angle-of-view of the rectilinear projection;
- transforming the rectilinear projection into a viewable video sequence that has a format suitable for playback in a virtual reality headset;
- and
- storing the viewable video sequence in electronic storage;
- wherein transforming the rectilinear projection into the viewable video sequence is performed such that the format suitable for playback in the virtual reality headset is a proprietary lat-long format;
- and
- wherein the proprietary lat-long format is compressed horizontally such that a first sub-portion in the center of the captured wide-angled video information is compressed less than a second sub-portion at the periphery of the captured wide-angled video information.
