    • Technologies for determining a distance of an object from a vehicle include a computing device to identify an object captured in a fisheye image generated by a fisheye camera of the vehicle. The computing device projects a contour of the identified object on a selected virtual plane that is located outside the vehicle and selected from a predefined set of virtual planes based on a location of the identified object relative to the vehicle. The computing device identifies a bottom of the projected contour on the selected virtual plane and determines an intersection point of an imaginary line with a ground plane coincident with a plane on which the vehicle is positioned. The imaginary line passes through each of the identified bottom of the projected contour and the fisheye camera. The computing device determines a location of the identified object relative to the vehicle based on the determined intersection point and the identified bottom of the projected contour.
    • 用于确定物体与车辆的距离的技术包括用于识别由车辆的鱼眼照相机生成的鱼眼图像中捕获的物体的计算装置。 所述计算设备在位于车辆外部的所选择的虚拟平面上投射所识别对象的轮廓,并且基于所识别的对象相对于所述车辆的位置从预定义的一组虚拟平面中选择。 计算装置识别所选择的虚拟平面上的投影轮廓的底部,并且确定假想线与与车辆所在的平面重合的接地平面的交点。 假想线穿过所识别的投影轮廓的底部和鱼眼相机。 计算设备基于所确定的交叉点和所识别的投影轮廓的底部来确定所识别的对象相对于车辆的位置。

    • 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。
