Abstract
A map of the surroundings for a motorized domestic appliance is created by transmitting signals and allocating reflections to points. A local distribution of the points is formed. Points are discarded if a correspondence of the distribution to a straight line fails to reach a predefined degree. In a second variant, points whose distance from an average location exceeds a predefined value are discarded. The surroundings may be divided into tiles. A normal distribution transformation for the points of a tile specifies an average location and a variance of the points. The variance has two eigenvectors in two dimensions, each with an eigenvalue describing the variance contained in the eigenvector. A ratio between the larger and smaller eigenvalues describes an equal or unequal distribution of the variances. If, however, the quotient is, say, 10 or more, a large number of points of the tile can lie along a straight line.
