  • Patent number: 11743419
    Abstract: The present disclosure relates to an apparatus and method for identifying light source. The method includes receiving an infrared image of an environment captured by an imaging apparatus in a first configuration. The method also includes identifying, based on the infrared image, that a light source exists in the environment captured in the infrared image. The method further includes generating an order for changing the imaging apparatus from the first configuration to a second configuration.

  • Publication number: 20220390284
    Abstract: The present disclosure relates to systems and methods for processing infrared data. The methods may include obtaining one or more raw infrared data frames related to a target object. Each of the one or more raw infrared data frames may include raw infrared data including raw temperature information and raw grayscale information of the target object. The methods may further include generating one or more target infrared data frames corresponding to the one or more raw infrared data frames based on the raw infrared data. Each of the one or more target infrared data frames may include a frame header, an information header, and a data area. And for at least one of the one or more target infrared data frames, the data area may include substantially complete raw temperature information and substantially complete raw grayscale information.

  • Patent number: 10815627
    Abstract: A method for improving the seismic performance of bridges by utilizing the beam body and an energy dissipation and seismic mitigation bridge bearing, which can effectively eliminate the harmful vibration of the bridge pier in the inherent frequency band, thus reducing the stress of the pier body and improving the seismic performance of the bridge pier without introducing external additional mass and looking for an installation space on the pier. The method includes the following steps: obtain the natural frequency fi, the equivalent modal mass Mi and the modal stiffness Ki of the pier in the longitudinal or transverse direction by numerical modal analysis or experimental modal test; determine the mass mi of the beam body; calculate the connection stiffness ki and the connection damping ci between the beam body and the pier; select the bearing system with above connection stiffness ki and the connection damping ci.
