  • Publication number: 20240142237
    Abstract: A localization device and a localization method for a vehicle are provided. The localization device includes an inertia measurer, an encoder, an image capturing device, and a processor. The processor obtains an encoded data by the encoder to generate a first odometer data, obtains an inertial data by the inertia measurer to generate a heading angle estimation data, and obtains an environmental image data by the image capturing device to generate a second odometer data. In a first fusion stage, the processor fuses the heading angle estimation data and the first odometer data to generate first fusion data. In a second fusion stage, the processor fuses the first fusion data, the heading angle estimation data and the second odometer data to generate pose estimation data corresponding to the localization device.

  • Patent number: 10600208
    Abstract: An object detecting device, an object detecting method and a non-transitory computer-readable medium are provided. The object detecting method includes the following steps: A classifier generates a current color image and a current gray scale image. The classifier generates an initial characteristic pattern from the current color image via a neural network algorithm. The classifier adjusts a current dimension of the initial characteristic pattern to generate an adjusted characteristic pattern according to a gray scale image dimension of the current gray scale image. The classifier concatenates the adjusted characteristic pattern and the current gray scale image to calculate a class confidence. The classifier determines whether the class confidence is larger than a confidence threshold, and outputs a current classification result if the class confidence is larger than the confidence threshold. A storage device stories the current classification result.
