Abstract: System and method for enhancing situational awareness. A moveable see-through display viewable by a user displays an augmented reality 2D image of an external scene based on received 2D image data, in accordance with updated position and orientation of display. The see-through display further displays an augmented reality 3D image of the external scene based on received 3D image data, the 3D image overlaid conformally onto view of external scene, in accordance with updated position and orientation of display. The see-through display further selectively displays: a gradual transition of the 2D image into the 3D image, or a gradual transition of the 3D image into the 2D image. At least one image feature may gradually appear or gradually disappear during the gradual transition. The 2D or 3D image may include a region of interest based on updated position and orientation of display or selected by user.

Abstract: Method and system for enhancing visual perception of augmented reality presentation. The location and line-of-sight (LOS) of a user wearing a see-through head-mounted display (HMD) is detected. A future background environment to be viewed by the user through the HMD is predicted based on at least the detected location and detected LOS. At least one color-attribute of the future background environment at a background location corresponding to a user LOS is predicted. The predicted color-attribute is compared with at least one color-attribute of an intended foreground supplementary image to be projected on the HMD overlaid onto the future background environment at the background location. When an incompatibility condition is detected, at least one visual parameter of the supplementary image is adjusted to minimize the incompatibility condition, and the supplementary image is projected on the HMD at the background location with the adjusted visual parameter.

Abstract: A system and method for generating a focused three-dimensional (3D) point cloud is disclosed. A respective 3D point cloud is generated based on returns of a respective sequence of energy pulses that is emitted towards one or more regions-of-interest (ROIs) within a field-of-view (FOV) during a respective scan of the FOV, the returns including one or more secondary returns from one or more points within the FOV. During an additional scan of the FOV, subsequent to the respective scan, an additional sequence of energy pulses is emitted to generate a focused 3D point cloud that includes additional information regarding one or more selected points of the points associated with the secondary returns relative to the respective 3D point cloud.

Abstract: A system determines a dynamic collision awareness envelope for a vehicle. The system includes at least one vehicle motion sensor, an operator Line-Of-Sight detector and a processor. The vehicle motion sensor periodically provides measurements relating to the motion of the vehicle in a reference coordinate system. The operator Line-Of-Sight detector periodically provides information relating to the direction of the Line-Of-Sight of an operator of the vehicle, in a vehicle coordinate system. The processor is coupled with the at least one vehicle motion sensor, and with the operator Line-Of-Sight detector. The processor determines an operator vector from the direction of the Line-Of-Sight of the operator. The processor further determines an operational vector at least from the motion of the vehicle. The processor periodically determines a collision awareness envelope respective of each of the operational vectors, from the operator vector and the respective operational vector.
