Sensor system for a road finishing machine

A non-transitory digital storage medium having a computer program stored thereon to perform a method for determining a distance to a reference and/or an angle with respect to the reference using a first laser scanner arranged on the construction machine and configured to search a specified angular range for objects and to determine corresponding distance values, which describe the distance to the one or several objects, together with corresponding intensity values, which describe an intensity of a reflection resulting at the one or several objects, across angles of the specified angular range, the method comprising:

• detecting an object as a reference together with an associated angle starting from a known pattern comprising the distance values and the intensity values across scanning angles, and
• determining a distance to the reference and the angle with respect to the reference;
• wherein said scanner is configured for being operated in a lateral perspective mode and in a bird's eye view mode,
• when said computer program is run by a computer.
