    • The invention relates to a method for determining the position (x, y) of at least one point of reflection (R1-2) on an obstacle. According to traditional methods of this kind a first distance (r1) between the point of reflection (R1-2) and a first position (x1) of a distance measuring device is calculated by evaluating a time period between the emission of a transmission signal and reception of a reflection signal. In order to state the unsharp position of the point of reflection thereby obtained even more precisely, in addition to the first distance (r1), a second distance (r2) of the point of reflection is calculated with respect to a second position (x2) of the distance measuring device in analogy to the calculation of the first distance (r1) and then a defined position (x, y) is calculated from the pair of variates (x1, r1) (x2, r2) so obtained using the triangulation method.
    • 本发明涉及一种用于确定障碍物上的至少一个反射点(R_1-2-2)的位置(x,y)的方法。 根据这种传统方法,反射点(R_1-2-2)与第一位置(x <1)之间的第一距离(r 1> 1 / SUB>)通过评估发射信号的发射与反射信号的接收之间的时间周期来计算。 为了更准确地说明由此获得的反射点的钝化位置,除了第一距离(r 1> 1)之外,第二距离(r 2> 2) 相对于距离测量装置的第二位置(x2> 2)来计算反射点,类似于第一距离(r 1> 1 N)和 那么从一对变量(x 1,r 1 1)(x 2,r 1,...,x 2)计算定义的位置(x,y) 使用三角测量方法获得。
