Claim 16:
17. The apparatus according to claim 16, wherein the coordinates of any feature point of the environmental target in the traveling coordinate system are determined according to the following steps:
determining a shortest distance from the reference line to the any feature point, and a point, corresponding to the shortest distance, on the reference line;
using a numerical value of the shortest distance as a numerical value of an ordinate of the any feature point in the traveling coordinate system;
determining a longitudinal arc length between the point on the reference line at the shortest distance to the any feature point and the coordinate origin OF; and
using a numerical value of the longitudinal arc length as a numerical value of an abscissa of the any feature point in the traveling coordinate system,
wherein whether the ordinate and the abscissa of the any feature point are positive or negative is determined according to the position of the feature point relative to the coordinate origin OF in the traveling coordinate system.
