  • Publication number: 20220309703
    Abstract: An apparatus for estimating a camera pose according to an embodiment of the present disclosure includes a similar image searcher, a clusterer, and an estimator. The similar image searcher searches for a plurality of images similar to an input image, from among a plurality of previously-stored images, based on the input image. The clusterer creates a cluster including at least some similar images meeting predetermined conditions, from among the plurality of similar images, based on viewpoint data tagged to each of the plurality of similar images. The estimator estimates a pose of a camera that has generated the input image, based on the cluster.

  • Publication number: 20220283231
    Abstract: An electric leakage detection apparatus for a battery included in an electric vehicle transmits a first voltage corresponding to a voltage between a negative terminal of the battery and a chassis of the electric vehicle to an analog-to-digital converter through a capacitor. The electric leakage detection apparatus transmits a second voltage corresponding to a voltage between a positive terminal of the battery and the chassis to the analog-to-digital converter through the capacitor. The analog-to-digital converter outputs digital signals indicating the first voltage and the second voltage using the negative terminal as the ground. The electric leakage detection apparatus determines the first voltage and the second voltage based on the digital signals, and detects an electric leakage between the battery and the chassis based on the first voltage and the second voltage.

  • Patent number: 11370386
    Abstract: An advanced driving assistance system (ADAS)-linked active hood apparatus for always-on operation is provided. The apparatus includes a rotary arm that is fixed to a hood of a vehicle, a stationary bracket fixed to a vehicle body, and a rotary bracket that rotates upward and downward by applied rotation force. A first link interconnects the rotary bracket and the stationary bracket. A motor unit is integrally connected to the rotary arm and applies driving force to the rotary bracket. A controller receives driving information of the vehicle via an ADAS and sets a pop-up height of the hood. The motor unit then performs pop-up and restoration of the hood when a collision is expected based on the received driving information.
