The invention relates to a method for determining the position (x, y) of at least one point of reflection (R) on an obstacle. According to traditional methods of this kind a first distance (r) between the point of reflection (R) and a first position (x) 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 (r), a second distance (r) of the point of reflection is calculated with respect to a second position (x) of the distance measuring device in analogy to the calculation of the first distance (r) and then a defined position (x, y) is calculated from the pair of variates (x, r) (x, r) so obtained using the triangulation method.
