Patents by Inventor CHANG-CHING LIAO

CHANG-CHING LIAO has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11453127
    Abstract: A method for ensuring safety of humans within operating area or in close proximity to an automatic apparatus is applied in and by a control apparatus. The control apparatus is coupled to one or more cameras arranged around the operating area of the automatic apparatus. The control apparatus uses deep learning techniques to analyze images captured by the cameras to determine whether there is a person in the operating area and powers off the automatic apparatus if any person is deemed present.
    Type: Grant

  • Patent number: 11176705
    Abstract: A method for optimizing camera layout for areas requiring surveillance comprises constructing a three-dimensional model of a scene subject to surveillance and related scene variables, configuring a computation range, constructing a plurality of simulation scenes using the three-dimensional model and the scene variables and recording the framing of pixels in the plurality of simulation scenes by a plurality of cameras according to the computation range, and further calculating the number of pixels required for visibility of an object to be recognized from the recorded framing of pixels. A camera set is selected from the plurality of cameras according to a convergence requirement, and a computation as to camera optimization layout is performed with the camera set to obtain one or more layout schemes.
