Method and arrangement for the automatic was detection and analysis of estate, structures from digitized topographical maps

摘要

A method for automatically building was detection and analysis of estate, structures from digitized topographical grid cards with the following steps:a) assignment of the objects in a building and not building - objects by means of a similarity object recorded in a parameter data base with the characteristic numbers for each of the objects of the topographic map corresponding to the morphological properties of the different resolution stages of the objects,b) removal of the not building - objects, whereby– Lines by using an erosion operation and a subsequent dilation operation on the digital map image of the topographical grid card,– Characters by means of an automatic analysing parameters of all objects of the segmented binary image with respect to its morphological properties and– Signature objects by means of special structure element parameters by means of identification and conversion into a new image from a comparison of the feature instances with the respectively selected object in predetermined tolerance limits in different resolution stages as well as subtraction of the new image by means of map - algebra from the building reason crack be removed after passage through all objects,c) determination of both building parameters as well as building distance parameters for the building objects, whereby the..
