<p>A surveying method wherein an object belongs to a group of known types of objects, and determining an object representing point corresponding to the type of the object, including determining a series of points at an object by measuring distances and angles to the points in a defined angle area, analyzing the spatial distribution of the points and, based thereon, assigning relevant points to a first group of points, identifying the type of the object on the basis of the first group of points, capturing an image of the object, extracting a contour of the object from the image by use of an image processing method, fitting at least one space curve to the object on the basis of the first group of points and the extracted contour, and determining the coordinates of the object representing point from the fitted space curve.</p> |
