Abstract
Sensor system for a construction machine, especially a road construction machine or paving machine, including: an optical detector which is arrangeable on the construction machine and configured to scan the underground in a predetermined angle so as to obtain measurement data describing one or more intensity values and/or one or more distance values plotted over the predetermined angle and a processor which is configured to analyse the measurement data so as to determine a pattern of intensity values and/or distance values in accordance with a predetermined pattern out of one or more predetermined patterns.

Sensor system for a construction machine, especially a road construction machine or paving machine, comprising:
- optical detector which is arrangeable on the construction machine and configured to scan the underground in a predetermined angle to the side so as to acquire measurement data describing one or more intensity values and one or more distance values plotted over the predetermined angle;
- a processor which is configured to analyse the measurement data so as to determine a pattern of intensity values and distance values in accordance with a predetermined pattern out of more predetermined patterns;
- wherein the one or more predetermined patterns comprising a milling edge pattern comprising two plateaus with a connection in between, wherein the connection is substantially perpendicular to the two plateaus or comprising an inclination angle within a range between 70° to 90°;
- and
- wherein the one or more predetermined pattern comprises a paving edge pattern comprising two plateaus comprising a connection in between, wherein the connection comprises an inclination angle of less than 70°;
- and
- wherein the one or more predetermined patterns comprise a curb stone edge pattern comprising two plateaus comprising a connection in between or a substantially perpendicular connection in between, wherein one edge comprises a roundness and/or wherein the spacing between the two edges is larger than 5 cm or 10 cm.
Method for performing a curb detection using a sensor system for a construction machine, especially a road construction machine or paving machine, comprising:
- scanning the underground in a predetermined angle to the side so as to acquire measurement data describing one or more intensity values and one or more distance values plotted over the predetermined angles;
- analysing the measurement data so as to determine a pattern of intensity values and distance values in accordance with a predetermined pattern out of more predetermined patterns;
- wherein the one or more predetermined patterns comprising a milling edge pattern characterized by two plateaus with a connection in between, wherein the connection is substantially perpendicular to the two plateaus or comprising an inclination angle within a range between 70° to 90°;
- and
- wherein the one or more predetermined pattern comprises a paving edge pattern characterized by two plateaus comprising a connection in between, wherein the connection comprises an inclination angle of less than 70°;
- and
- wherein the one or more predetermined patterns comprise a curb stone edge pattern characterized by two plateaus comprising a connection in between or a substantially perpendicular connection in between, wherein one edge comprises a roundness and/or wherein the spacing between the two edges is larger than 5 cm or 10 cm.
A non-transitory digital storage medium having a computer program stored thereon to perform the method for performing a curb detection using a sensor system for a construction machine, especially a road construction machine or paving machine, the method comprising:
- scanning the underground in a predetermined angle to the side so as to acquire measurement data describing one or more intensity values and one or more distance values plotted over the predetermined angles;
- analysing the measurement data so as to determine a pattern of intensity values and distance values in accordance with a predetermined pattern out of more predetermined patterns;
- wherein the one or more predetermined patterns comprising a milling edge pattern characterized by two plateaus with a connection in between, wherein the connection is substantially perpendicular to the two plateaus or comprising an inclination angle within a range between 70° to 90°;
- and
- wherein the one or more predetermined pattern comprises a paving edge pattern characterized by two plateaus comprising a connection in between, wherein the connection comprises an inclination angle of less than 70°;
- and
- wherein the one or more predetermined patterns comprise a curb stone edge pattern characterized by two plateaus comprising a connection in between or a substantially perpendicular connection in between, wherein one edge comprises a roundness and/or wherein the spacing between the two edges is larger than 5 cm or 10 cm,
- when said computer program is run by a computer.
