摘要： This invention concerns an ergonomic optical see-through head mounted display device with an eyeglass appearance. The see-through head-mounted display device consists of a transparent, freeform waveguide prism for viewing a displayed virtual image, a see-through compensation lens for enabling proper viewing of a real-world scene when combined together with the prism, and a miniature image display unit for supplying display content. The freeform waveguide prism, containing multiple freeform refractive and reflective surfaces, guides light originated from the miniature display unit toward a user's pupil and enables a user to view a magnified image of the displayed content. A see-through compensation lens, containing multiple freeform refractive surfaces, enables proper viewing of the surrounding environment, through the combined waveguide and lens. The waveguide prism and the see-through compensation lens are properly designed to ergonomically fit human heads enabling a wraparound design of a lightweight, compact, and see-through display system.

摘要： Bit data is encoded into characters in an input image by providing different darkness levels for pixels in either half of a text character. In order to detect document skew angle error prior to attempting to extract an encoded message, the orientation angle of text line(s) in the input image is determined, and a document skew angle is estimated from the line orientation angle(s). A Hough transform may be used to estimate line orientation angle. To determine if an input image of a document is orientated horizontally or vertically, the input image may be scanned for text characters along a first reference angle, and along a second angle 90° to the first angle. The scan that provides the higher number of potential text character is selected as the correct orientation for the input image.

摘要： Bit data is encoded into characters in an input image by providing different darkness levels for pixels in either half of a text character. To determine if the input image is of a right-side up document, or an upside-down document, multiple scans of the input image at 90° rotations between scans may be made. Each scan result is searched for occurrences of a indicator prefix bit-sequence. The scan that contains the indicator prefix bit-sequence is elected as the right-side up orientation for the input image. If multiple scans show occurrences of the indicator prefix bit-sequence, then the scan that has the highest number of occurrences is elected as the correct orientation. Alternatively, the number of data bits between repeated occurrences of the indicator prefix bit-sequence is compared with a predefined message bit size, and the scan that matches most closely is elected as the correct orientation.

摘要： Aspects of the present invention involve novel three-dimensional display systems. Multi-view-window-based display systems are used to generate floating three-dimensional displays. In embodiments, an optical focusing element is positioned at a distance that is greater than or equal to the focal length of the optical focusing element from the viewing windows to form projected viewing windows through which a user can see a floating 3D image. In alternative embodiments, an optical focusing element is positioned at a distance that is less than the focal length of the optical focusing element from the viewing windows to form a rear-projection-like three-dimensional display system. In embodiments, a retro-reflective light diffusion screen is used in the multi-view-window-based display systems.

摘要： Crosstalk artifacts in a retro-reflective auto-stereoscopic 3D display system are compensated by providing various methods of directing surface reflections of a screen away from a viewing region, i.e. a region from which the screen is viewed. This is achieved by splitting the screen in two, and tilting the left-side and right-side of the screen either towards, or away, from a projection baseline so as to direct mirror reflections away from the viewing region. Alternatively, the screen is not split, but vertical v-shaped grooves are made along the surface of the screen facing the projection line. The angle of the v-shaped grooves direct surface reflections away from the viewing region, but the grooves are substantially small so that the screen appears flat to an observer.

摘要： A panoramic 3D image is created by using multiple projectors whose field-of-view is narrower than the screen's width. Each projector provides a different image of a common subject from a different view angle, and the different images are mosaiced onto the screen. An observer may have a limited view of the composite image depending on which projectors are within the observer's field-of-view. A viewing volume is also extended by using space beyond a far limit line dependent upon the observer's inter-pupillary distance, the width of each projector's viewing window, and the distance from the projection baseline to the screen.
