The present disclosure provides systems and methods for mapping a vehicle environment. A computer-implemented method for mapping a vehicle environment, the method comprising: a) defining a first grid in an earth reference frame having a first coordinate system; b) initializing the position of the carrier in the first grid and a first group of cell occupancy values of the first grid; c) receiving sensor data of the surroundings of the vehicle from one or more sensors on the vehicle; d) updating the first grid with a second set of cell occupancy values calculated at least in part from the sensor data; and e) calculating one or more absolute velocities of one or more objects in the earth reference frame as a function of a change in the cell occupancy value of the first grid. 本公开提供用于映射载具环境的系统和方法。一种用于映射载具环境的由计算机实现的方法，该方法包括：a)在具有第一坐标系的地球参考系中定义第一网格；b)初始化所述载具在所述第一网格中的位置和所述第一网格的第一组小区占用值；c)从所述载具上的一个或更多个传感器接收所述载具的周围环境的传感器数据；d)用至少部分地根据所述传感器数据计算的第二组小区占用值来更新所述第一网格；以及e)根据所述第一网格的小区占用值的变化来计算一个或更多个对象在所述地球参考系中的一个或更多个绝对速度。
