METHOD AND DEVICE FOR DETERMINING THE POSITION OF AT LEAST ONE POINT OF REFLECTION ON AN OBSTACLE |
摘要 |
<p>The invention relates to a method for determining the position (x, y) of at least one point of reflection (R<SUB>1-2</SUB>) on an obstacle. According to traditional methods of this kind a first distance (r<SUB>1</SUB>) between the point of reflection (R<SUB>1-2</SUB>) and a first position (x<SUB>1</SUB>) 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<SUB>1</SUB>), a second distance (r<SUB>2</SUB>) of the point of reflection is calculated with respect to a second position (x<SUB>2</SUB>) of the distance measuring device in analogy to the calculation of the first distance (r<SUB>1</SUB>) and then a defined position (x, y) is calculated from the pair of variates (x<SUB>1</SUB>, r<SUB>1</SUB>) (x<SUB>2</SUB>, r<SUB>2</SUB>) so obtained using the triangulation method.</p> |
