摘要： Apparatus, system, and method for providing an augmented reality (AR) display. The system includes a panel comprising: a first linear polarizer configured to allow light from an object to transmit through as a polarized light; and a liquid crystal layer disposed on the first linear polarizer and at an opposite side with respect to the object, the liquid crystal layer comprising an array of liquid crystal pixels corresponding to AR content, each pixel configured to modify the polarized light; eyeglasses worn by a user and configured to directly receive the modified polarized light, at least one lens of the eyeglasses comprising a second linear polarizer; at least one camera configured to acquire at least one image of the user to obtain a face position of the user; and a controller configured to render the AR content based on the face position.

摘要： A three-dimensional (3D) object scanning method includes: controlling, when an invisible light source is off, a first camera device to capture a first image of the target object; and controlling, when the invisible light source is on, a second camera device to capture second images of the target object from a plurality of viewing angles. The target object is painted with invisible markers that are invisible to the first camera device when the invisible light source is off. The invisible markers are visible to the second camera device upon absorbing a light emitted by the invisible light source. The second images are used to determine 3D information of the target object.
