A system for continuous image alignment of separate cameras identifies a reference camera transformation matrix between a base reference camera pose and an updated reference camera pose. The system also identifies a match camera transformation matrix between a base match camera pose and an updated match camera pose and an alignment matrix based on visual correspondences between one or more reference frames captured by the reference camera and one or more match frames captured by the match camera. The system also generates a motion model configured to facilitate mapping of a set of pixels of a reference frame captured by the reference camera to a corresponding set of pixels of a match frame captured by the match camera based on the reference camera transformation matrix, the match camera transformation matrix, and the alignment matrix.

A system for facilitating the identifying of correspondences between images experiencing motion blur obtains a reference frame captured by a reference camera at a reference camera and obtains a match frame captured by a match camera at a match camera timepoint. The system identifies a motion attribute that includes (1) a reference camera motion attribute associated with the reference camera at the reference camera timepoint, and/or (2) a match camera motion attribute associated with the match camera at the match camera timepoint. The system determines a downsampling resolution using at least as inputs at least one of: the motion attribute, a camera exposure time, a camera field of view, or a camera angular resolution. The system generates a downsampled reference frame and a downsampled match frame based on the downsampling resolution. The system identifies correspondences between the downsampled reference frame and the downsampled match frame.

A system for updating continuous image alignment of separate cameras identifies a previous alignment matrix associated with a previous frame pair captured at one or more previous timepoints by a reference camera and a match camera. The previous alignment matrix is based on visual correspondences in the previous frame pair. The system also identifies a current matrix associated with a current frame pair captured at one or more current timepoints by the reference camera and the match camera. The current matrix is based on visual correspondences in the current frame pair. The system also identifies a difference value associated with the reference camera or the match camera relative to the one or more previous timepoints and the one or more current timepoints. The system also generates an updated alignment matrix by using the previous alignment matrix, the current matrix, and the difference value as inputs.

The invention relates to an electronic device for managing the display of a head-up display system capable of being embarked in a cockpit of an aircraft piloted by at least one pilot and comprising: a display module configured to display a plurality of symbols relative to the operation of the aircraft and its environment in at least two distinct visualization planes, the visualization planes each having a distinct depth along a line of sight from the pilot, a determination module configured to determine a reference visualization plane corresponding to an accommodation plane of the eye of the pilot and a warning module configured to generate a warning to be displayed in the reference visualization plane.

A heads-up display apparatus adapted to be mounted to a helmet or item of headgear to display an image to a user includes a housing and an image projection system. The image projection system includes an electronic display, a display controller adapted to receive and process data presented on the electronic display, an aspherical lens, a semi-transparent display panel locatable in a line of sight of a user, and a front surface mirror for reflecting light emitted from the electronic display through the aspherical lens onto the semi-transparent display panel. The electronic display, the aspherical lens and the front surface mirror are arranged within the housing, and the heads-up display apparatus minimises refocusing of an eye of a user when looking from a primary task to the display and back to the primary task.

A method of transitioning between a first virtual reality view and a second virtual reality view within media content of a virtual reality environment is described. The method comprises: sending the first virtual reality view containing the media content to a virtual reality device over a first network path; determining a second, different, virtual reality view containing media content; sending at least a section of the second virtual reality view to the virtual reality device over a second network path, the latency of the second network path being less than the latency of the first network path.

Aspects of the present invention relate to providing assistance to medical professionals during the performance of medical procedures through the use of technologies facilitated through a head-worn computer.

A method for testing for visual impairment is provided. The method includes rendering, via a computing device communicatively coupled to a head mounted holographic display device, a virtual target displayed to a user within the holographic display device. The method further includes rendering, via the computing device, at least one virtual light within a field of vision of the user within the holographic display device. The method also includes identifying, via the computing device, whether input was received from the user, wherein the input comprises an indication that the user identified the at least one virtual light. The method further includes generating, via the computing device, a map identifying one or more locations that the user identified the at least one virtual light or did not identify the at least one virtual light.

A method for controlling a display apparatus comprising a head-up display or a motor vehicle, in which, depending on a signal provided by a sensor device, a height adjustment and/or a rotation of a depiction of a piece of information dependent on the signal is carried out autonomously through a control device. In this case, the signal correlates with a color and/or a brightness of a projection background and/or correlates with a relative movement between the projection background and a projection surface. Through the method, it is possible to ensure an especially good and reliable perceptibility of the depicted piece of information. The invention further relates to a display apparatus for a motor vehicle that is equipped to carry out the method and to a motor vehicle having such a display apparatus.

Aspects of the present invention relate to methods and systems for imaging, recognizing, and tracking of a user's eye that is wearing a HWC. Aspects further relate to the processing of images reflected from the user's eye and controlling displayed content in accordance therewith.
