A panoramic image system with parallax mitigation includes image sensors, a head tracker, a display, and a processor. Each image sensor is fixedly mounted a predetermined linear distance from a first reference axis and is disposed adjacent to at least one other image sensor and to point in a direction that is offset from its adjacent image sensor by a predetermined angle. The head tracker is configured to sense at least the angular position and movement direction of a viewer's head about a second reference axis and to supply an azimuth position signal representative thereof. The display is configured to selectively display images sensed by each of the image sensors. The processor is in operable communication with the image sensors, head tracker, and display. The processor is configured, based at least on the azimuth position signal, to command the display to display images sensed by only one image sensor.

Panoramic vision system with parallax mitigation

A method for displaying images on a head-mounted display (HMD) device that compensates for a user's vestibulo-ocular reflex (VOR) response. The displayed HMD image is compensated for predicted eye position such that the displayed image stays centered on the fovea of the eye, during transient eye movement caused by head motion, resulting in better display readability, discernment and cognitive processing.

This dual rate system then enables a head-tracked augmented reality system to be updated at the high rate, reducing latency based artifacts.

A method and a computer readable medium containing instructions for devices marking pixel data as being critical symbology pixel data for verification prior to being displayed a pixel on a display device is presented. The method comprises determining by a computing device whether the pixel data is critical symbology pixel data and assigning an intensity threshold level to the pixel data. The threshold is based at least in part on the status of the pixel data as being critical symbology pixel data. Further, the method includes determining whether an intensity of the pixel data is less than or equal to the assigned intensity threshold level and then marking the pixel data as critical symbology pixel data when the intensity of the pixel data is greater than the intensity threshold.

Dual processor accelerated graphics rendering is a method which allows for optimizing graphics performance using two processors and 3D hardware accelerators. This method allows for real time embedded systems to have multiple partitions to render to multiple windows with non-blocking graphics calls. One processor queues up graphics calls within a discrete time because they do not interface with the graphics accelerator hardware. The second processor supports the hardware accelerator with drivers operating in a single partition. This design abstracts the graphics calls from the native interface of the graphics hardware accelerator.

A method for generating anti-aliased lines and characters is disclosed. The method comprises generating a texture map based on a distribution and applying the texture map to a polygonal region. In one aspect of this embodiment, the step of generating a texture map based on a distribution further comprises generating a texture map comprising a series of concentric half circles. In the texture map, the concentric half circles represent a decreasing intensity as the radius of the concentric half circle increases. Additionally, in one embodiment, the texture map is generated using a Gaussian distribution. In another aspect of this embodiment, for each texel in a texture map defining a character, the smallest distance between a texel and each line segment that forms a character is calculated. The smallest distance is used to determine an intensity value using the distribution. Then, the texel is associated with the intensity value to form a texture map for the character. Optionally, a halo value for each texel value can be determined by using the smallest distance found in conjunction with a second distribution to determine a halo value for each texel. This method can be repeated for each character to be displayed.
