Abstract

A method for the representation in a computer unit with a display unit of detected metal objects that were detected by means of one or a plurality of ground detectors, for example metal detectors and/or ferrous metal detectors, and suitable detectors for the application of the method. The measured data of an examined area of measurement measured by a detector at certain positions are stored in conjunction with the position in question and, from the data of identified detected objects, coherent data structures with a certain similar measuring intensity associated with said data are generated that are then assigned a georeference of a georeference system. By means of a graphic information system (GIS), the georeferenced coherent data structures in the form of polygon courses and/or filled polygon areas are linked with the data of an earth surface image, and the georeferenced coherent data structures are displayed superimposed on the earth surface image.

Claims

1. A method for graphically representing in a computer unit with a display unit objects of an area of measurement that were detected by means of one or a plurality of ground detectors, comprising:

storing each measured datum of an examined area of measurement measured by a detector with its position,

combining in data groups the data of identified detected objects that are associated with said object,

generating coherent data structures with a certain similar measuring intensity from the data associated with each of the identified detected objects,

assigning at least one georeference of a georeference system to the data or to the coherent data structures associated with a detected object,

storing the coherent data structures with a certain similar measuring intensity, arranged in a given sequence, in a data format suitable for further processing, and

linking the georeferenced coherent data structures to the data of an earth surface image in a graphic information system (GIS), and displaying the earth surface image with the georeferenced coherent data structures on the display unit of the computer unit as polygon courses and/or filled polygon areas.

2. The method according to claim 1, wherein isolines are formed from the data for generating the coherent data structures.

3. The method according to claim 1, wherein, for integrating the georeferenced coherent data structures, followed by their display, the generated data structure with measured data of lower value is displayed first in the graphic information system.

4. The method according to claim 1, wherein the position data of the measuring points are displayed in the sequence of their detection, linked to the georeferenced polygon courses and/or filled polygon areas, and in the form of a continuous series of lines.

5. The method according to claim 1, wherein the georeference is associated with a group of data.

6. A ground detector with a computer unit for representing detected objects, wherein data of equal measuring intensity are shown as coherent data structures in the form of polygon courses and/or polygon areas, and wherein at least one georeference of a georeference system is assigned to the data of the coherent data structures, and wherein the georeferenced polygon courses and/or polygon areas are displayed superimposed on an image of the earth surface, with the computer unit including at least the following:

a first storage device that stores the measured data of each detector and each related detector position in association with each other,

a first program module that generates coherent data structures for an identified detected object from data of equal measuring intensity,

a second program module that assigns a georeference to the data or the coherent data structures,

a second storage device that stores the coherent data structures of equal measuring intensity arranged in a given sequence in a data format that is suitable for further processing,

a display unit that displays the georeferenced coherent data structures superimposed on an earth surface image, and

a graphic information system that links the georeferenced coherent data structures with the data of the earth surface image and displays them as polygon courses and/or polygon areas superimposed on the earth surface image.

7. The ground detector with the computer unit according to claim 6, wherein isolines are formed from the data for generating the coherent data structures.

8. The ground detector with the computer unit according to claim 6, wherein, for integrating the georeferenced coherent data structures, followed by their display, the generated data structure with measured data of lower value is displayed first in the graphic information system.

9. The ground detector with the computer unit according to claim 6, wherein the position data of the measuring points are displayed in the sequence of their detection, linked to the georeferenced polygon courses and/or filled polygon areas, and in the form of a continuous series of lines.

10. The ground detector with the computer unit according to claim 6, wherein the georeference is associated with a group of data.
