Reducing Driver Distraction Using a Heads-Up Display

Driver distraction is reduced by providing information only when necessary to assist the driver, and in a visually pleasing manner. Obstacles such as other vehicles, pedestrians, and road defects are detected based on analysis of image data from a forward-facing camera system. An internal camera images the driver to determine a line of sight. Navigational information, such as a line with an arrow, is displayed on a windshield so that it appears to overlay and follow the road along the line of sight. Brightness of the information may be adjusted to correct for lighting conditions, so that the overlay will appear brighter during daylight hours and dimmer during the night. A full augmented reality is modeled and navigational hints are provided accordingly, so that the navigational information indicates how to avoid obstacles by directing the driver around them. Obstacles also may be visually highlighted.

Autonomous electro-optical framing camera system with constant ground resolution, unmanned airborne vehicle therefor, and methods of use

An aerial reconnaissance system generates imagery of a scene that meets resolution or field of view objectives automatically and autonomously. In one embodiment, a passive method of automatically calculating range to the target from a sequence of airborne reconnaissance camera images is used. Range information is use for controlling the adjustment of a zoom lens to yield frame-to-frame target imagery that has a desired, e.g., constant, ground resolution or field of view at the center of the image despite rapid and significant aircraft altitude and attitude changes. Image to image digital correlation is used to determine the displacement of the target at the focal plane. Camera frame rate and aircraft INS / GPS information is used to accurately determine the frame to frame distance (baseline). The calculated range to target is then used to drive a zoom lens servo mechanism to the proper focal length to yield the desired resolution or field of view for the next image. The method may be performed based on parameters other than range, such as aircraft height and stand off distance.

System and method for object tracking

A hand-manipulated prop is picked-up via a single video camera, and the camera image is analyzed to isolate the part of the image pertaining to the object for mapping the position and orientation of the object into a three-dimensional space, wherein the three-dimensional description of the object is stored in memory and used for controlling action in a game program, such as rendering of a corresponding virtual object in a scene of a video display. Algorithms for deriving the three-dimensional descriptions for various props employ geometry processing, including area statistics, edge detection and / or color transition localization, to find the position and orientation of the prop from two-dimensional pixel data. Criteria are proposed for the selection of colors of stripes on the props which maximize separation in the two-dimensional chrominance color space, so that instead of detecting absolute colors, significant color transitions are detected. Thus, the need for calibration of the system dependent on lighting conditions which tend to affect apparent colors can be avoided.
