Abstract: An image capturing and depth alignment method includes radar scanning step, image capturing step, translation and synchronization step, alignment step, client detection step, client positioning step, scene map construction step, view image transmitting step, view image processing step, virtual object placement step. through translating, synchronizing, and aligning the radar scanning step's 3D point cloud map and the image capturing step's planar image of the scene, the back-end server therefore obtains surveillance information with both image and depth. Then, through positioning, multiply superimposing, image rotation and matching, speed comparison, uniformization of coordinate systems, and display through the smart glasses, a wearer of the smart glasses may be positioned and tracked in the scene. The wearer may also be instructed to reach a specific target or place of a specific object.

Abstract: An augmented reality display device configured to be disposed on a head of a user includes a display, a relay lens set, a beam splitting module, and a curved mirror. The display is configured to emit an image beam. The relay lens set is disposed on a path of the image beam. The beam splitting module is disposed on a path of the image beam from the relay lens set. The curved mirror is configured to reflect the image beam from the beam splitting module back to the beam splitting module. The image beam reflected by the curved mirror penetrates through the beam splitting module and is then transmitted to a pupil of the user. The beam splitting module includes a polarizer, a brightness enhancement film, and a phase retardation film stacked together in sequence from a side adjacent to the pupil to a side adjacent to the curved mirror.

Abstract: An ocular optical system configured to allow imaging rays from a display image to enter an observer's eye through the ocular optical system so as to form an image is provided. A direction toward the eye is an eye side, and a direction toward the display image is a display side. The ocular optical system includes a first lens element, a second lens element, and a third lens element arranged along an optical axis in sequence from the eye side to the display side. Each of the first to third lens elements has an eye-side surface and a display-side surface. The ocular optical system satisfies: 0<f/f1+f/f2+f/f3<0.35, where f is an effective focal length of the ocular optical system, f1 is a focal length of the first lens element, f2 is a focal length of the second lens element, and f3 is a focal length of the third lens element.

Abstract: A glasses assembly with a nose pad for high load includes: a pair of glasses, configured with an accommodation portion, where the glasses are smart glasses; a support, configured with a first fixing portion, at least one second fixing portion, and the first fixing portion inserted in the accommodation portion of the glasses; and a flat nose pad, two sides thereof respectively configured with a fixed portion, each of the fixed portions installed on the second fixing portion of the support. With the flat nose pad being worn on the user's nose bridge to form a fulcrum, the glasses, smart glasses can achieve leverage balance through the flat nose pad, and the flat nose pad can buffer the weight of the glasses, smart glasses, capable of significantly reducing the user's discomfort after wearing them for a long time, and preventing them from slipping downward.

Abstract: An integrated endoscope and visualization system comprises an endoscope, a visualization processing module and a 3D display device such as smart-glasses or naked-eye 3D display. The endoscope is equipped with two image capturing modules such as CMOS image sensors and can be disposable. The visualization processing module receives and encodes the images obtained by the two image capturing modules in order to generate an output visualization signal. The output visualization signal is transmitted to and displayed by the 3D display device in a 3D manner. The integrated endoscope and visualization system not only provides a 3D vision of surgical target during an endoscopic surgery operation, but also allow the medical personnel to walk or move during the surgery while keeping looking at the 3D images captured by the endoscope through wearable display devices.
