An optical glass may be used for the lens that has a higher refractive index than can be provided by optical plastic which allows the lens to be thinner than plastic lenses. The lenses may be formed by molding a glass wafer to form lens shapes on a first surface of the wafer; the molded wafer is then ground from a second surface to singulate the lenses.

  • Patent number: 10873702
    Abstract: Embodiments include devices and methods for adaptive image processing in an unmanned autonomous vehicle (UAV). In various embodiments, an image sensor may capture an image, while a processor of the UAV obtains attitude information from one or more attitude sensors. Such information may include the relative attitude of the UAV and changes in attitude. The processor of the UAV may determine a UAV motion mode based, at least in part, on the obtained attitude information. The UAV motion mode may result in the modification of yaw correction parameters. The processor of the UAV may further execute yaw filtering on the image based, at least in part, on the determined motion mode.

  • Patent number: 10791271
    Abstract: Implementations of the present application provide a solution for obtaining a stable frame. In the solution, a video stream is obtained, from which a first and second stable frame are determined using at least position-based offset values between one or more frames. The first and second stable frames correspond to a first time interval and second time interval, respectively. The first time interval corresponds to a time before a first vibration is generated by opening a door of a visual vending machine. The second time interval corresponds to a time after the first vibration and before a second vibration generated by closing the door. The two stable frames can be used for image recognition within the visual vending machine to improve accuracy of product recognition.
