    • An apparatus for generating an overview image of a plurality of images comprises a storage unit and an image processor. The storage unit stores a plurality of processed images of the overview image and is able to provide the overview image containing the plurality of processed images at their assigned positions for displaying. The image processor determines feature points of a new image and compares the determined feature points of the new image with feature points of a stored processed image to identify common feature points and to obtain 3-dimensional positions of the common feature points. Further, the image processor determines common feature points located within a predefined maximum distance of relevance to a reference plane based on the 3-dimensional positions of the common feature points to identify relevant common feature points. Further, the image processor processes the new image by assigning the new image to a position in the overview image based on a comparison of an image information of each relevant common feature point of the new image with an image information of each corresponding relevant common feature point of the stored processed image without considering common feature points located beyond the predefined maximum distance of relevance to the reference plane.
    • 用于生成多个图像的概览图像的装置包括存储单元和图像处理器。 存储单元存储概览图像的多个处理图像,并且能够在其分配位置处提供包含多个处理图像的概览图像以进行显示。 图像处理器确定新图像的特征点,并将确定的新图像的特征点与存储的处理图像的特征点进行比较,以识别公共特征点并获得公共特征点的3维位置。 此外,图像处理器基于公共特征点的3维位置来确定位于与参考平面相关的预定最大距离内的公共特征点,以识别相关的公共特征点。 此外,图像处理器基于将新图像的每个相关公共特征点的图像信息与每个相应的相关公共特征点的图像信息进行比较,将新图像分配给概览图像中的位置来处理新图像 不考虑位于与参考平面相关的预定最大距离之外的公共特征点。

    • Embodiments described herein comprise a system and method for improving visibility of a roadway using an improved visibility system. The method comprising receiving data from a plurality of fog detectors located proximate a roadway and determining, based on the data from the plurality of fog detectors, that fog is present about the roadway. The method further comprising obtaining, after the determining that fog is present about the roadway, a plurality of images of the roadway by activating a plurality of cameras located proximate the roadway. The method further comprising creating a composite image by combining two or more of the plurality of images, wherein the composite image depicts the roadway unobstructed by fog and transmitting the composite image to a display device located in a vehicle traveling along the roadway.
    • 本文描述的实施例包括使用改进的可见性系统来改善道路的可见性的系统和方法。 该方法包括从位于道路附近的多个雾化检测器接收数据,并且基于来自多个雾化检测器的数据确定关于道路的灰雾存在。 该方法还包括通过激活位于道路附近的多个摄像机,在确定了关于道路的雾之后,获得道路的多个图像。 所述方法还包括通过组合所述多个图像中的两个或更多个来创建合成图像,其中所述合成图像描绘通过雾而不阻挡的道路,并将所述合成图像发送到位于沿所述道路行驶的车辆中的显示装置。
