  • Patent number: 10742952
    Abstract: A 3D reconstruction method is provided. Positioning signals are received by a signal receiver at a first and a second time spots to determine a HMD displacement vector and a HMD rotation amount. A first and a second images are retrieved by a first camera to determine a first camera rotation amount. A relative rotation amount and a relative displacement vector between the HMD and the first camera are calculated. A first camera displacement vector of the first camera is calculated according to the HMD displacement vector, the HMD rotation amount, the relative rotation amount and the relative displacement vector. Depth information of the first and the second image is obtained based on the first camera displacement vector and the first camera rotation amount. 3D reconstruction is performed according to images retrieved by the first camera and the depth information.

  • Patent number: 10255508
    Abstract: An image evaluation method and an electronic apparatus thereof are provided. The method is adapted to the electronic apparatus installed at a vehicle for evaluating whether the vehicle is deviated from a lane, and the electronic apparatus includes at least one image capture unit. The method includes the following steps. An image related to driving environment is obtained by the image capture unit. According to an evaluation criterion, a plurality of candidate pair and corresponding candidate points in the image are evaluated from an arbitrary row of pixels of the image to recognize lane stripes in the image. A corresponding position of a feature portion of the vehicle corresponding to the image is calculated. The corresponding position of the feature portion corresponding to the image is compared with the lane stripes to determine whether the vehicle is towards or crosses over real lane stripes.
