    Abstract: A method and device for fisheye camera automatic calibration is disclosed. A first straight line and a second straight line are respectively moved to generate a first fisheye line and a second fisheye line being straight lines. At least two symmetric points are generated on the second straight line based on an intersection of the first straight line and the second straight line as a symmetric central point, so as to correspondingly generate at least two fisheye symmetric points. The second straight line rotates until a distance between the first fisheye line and each of two fisheye symmetric points is equal.

  • Publication number: 20170316610
    Abstract: Assembly instruction system includes at least one depth camera, database, processor, and display. Depth camera captures first object image. Database stores multiple known object images and assembly tree. Processor compares first object image with known object images separately to recognize first object corresponding to first object image and a three-dimensional position and orientation of first object, and obtains second object (or some other multiple objects) corresponding to first object according to captured image and assembly tree. Processor generates at least one virtual arrow according to three-dimensional position and orientation. Display displays augmented reality image having at least one virtual arrow added on first object image and second object (or some other multiple objects) image(s). Virtual arrow indicates a moving direction for assembling first object and second object (or some other multiple objects). The above process is repeatedly performed until the whole device is assembled.

    Abstract: A multi-function control illumination device has a synchronization separator, a parameter setting device, a light emitting device, and a video processor. The synchronization separator connects with a video camera and the parameter setting device connecting with the light emitting device. The synchronization separator receives a video signal from the video camera, retrieves a synchronization signal from the video signal, and outputs the synchronization signal to the parameter setting device. The parameter setting device generates an electric signal corresponding to the synchronization signal according to at least one illumination parameter and outputs the electric signal to the light emitting device. The light emitting device emits toward a shooting direction of the video camera a light beam whose intensity periodically varies according to the electric signal.
