    • A system operable to generate a surround view based on image data, where the image data may include image data associated with surroundings of an object, such as a vehicle. The system may also be operable to project the surround view inversely onto a bowl-shaped projection surrounding the object. Further, the system may be operable to generate a virtual user view via a virtual camera position, where the virtual camera position is on a first horizontal ellipse that is about the bowl-shaped projection at a first height. Also, the system is operable to determine a viewing direction from the virtual camera position that points at a location on a second horizontal ellipse that is about the bowl-shaped projection at a second height. The second height may be lower than the first height and the second horizontal ellipse may be smaller than the first horizontal ellipse.
    • 一种可操作以基于图像数据生成环绕视图的系统,其中所述图像数据可以包括与物体(例如车辆)的环境相关联的图像数据。 该系统还可以可操作地将环绕视图反向投影到围绕物体的碗状突起上。 此外,该系统可以可操作以经由虚拟相机位置生成虚拟用户视图,其中虚拟相机位置在第一高度上围绕碗状突起的第一水平椭圆上。 而且,该系统可操作以确定来自虚拟相机位置的观察方向,其指向位于第二高度处的碗形突起的第二水平椭圆上的位置。 第二高度可以低于第一高度,并且第二水平椭圆可以小于第一水平椭圆。

    • A system for calibrating a surround view system of an object, such as a vehicle. The system may be implemented via calibration logic that may include software, hardware, firmware, or a combination thereof. The system may include positioning a set of markers on a plane at least partially surrounding the object. The plane may be in a field of view of a camera of the surround view system, and the camera may include a predetermined intrinsic calibration. The system may also include determining a first plurality of extrinsic parameters of the camera with respect to the set of markers. The system may repeat the positioning of the set of markers and the determination of the first plurality of extrinsic parameters for at least one other camera of the surround view system.
    • 一种用于校准诸如车辆的物体的环视系统的系统。 该系统可以通过可以包括软件,硬件,固件或其组合的校准逻辑来实现。 该系统可以包括将一组标记定位在至少部分地围绕物体的平面上。 平面可以在环绕视图系统的相机的视场中,并且相机可以包括预定的内在校准。 系统还可以包括相对于该组标记来确定摄像机的第一多个非本征参数。 该系统可以重复该组标记的定位以及对环绕视图系统的至少一个其他相机的第一多个非本征参数的确定。
