<p>The invention concerns a surveying method for measuring an object, wherein the object belongs to a group of known types of objects, and determining an object representing point corresponding to the type of the object, by a surveying instrument (1) with means for measuring distances and angles and a camera, comprising the steps of: determining a series of points (6e, 6f, 6g) at an object (21, 27) by measuring distances and angles to the points in a defined angle area, analysing the spatial distribution of the points and, based thereon, assigning relevant points to a first group of points (6e), identifying the type of the object (21) on the basis of the first group of points (6e), capturing an image of the object (21), extracting a contour of the object (21) 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> |
