Method for determining the position of a sensor with respect to a longitudinal guide strip, for moving vehicle guidance in public works |
摘要 |
The method is used to determine the position of a sensor (1), having a image generator (4), with respect to a longitudinal strip. The method has the following stages: an initial image (I) is formed, of at least part of the strip (2), by the image generator (4). The longitudinal strip (2) has a characteristic motif (M1, M2) which is periodically and symmetrically reproduced along its axis (AL); from the initial image (I) a processed image is formed which includes at least a first correlation; from the results of this first correlation the position of the axis (AL) is determined in an image reference field; measurements are taken at a number of points along the axis (AL) so as to determine the distance between the periodically reproduced characteristic motif and the axis; from these distance measurements, the position of the sensor (I) with respect to the longitudinal strip (2) is determined. |
