1. Sensor system for a construction machine, in particular a road finishing machine, comprising:
a first laser scanner that can be arranged on the construction machine and is 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,
an evaluation unit configured to detect 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
configured to determine a distance to the reference and the angle with respect to the reference;
wherein the evaluation unit is configured for being operated in a lateral perspective mode and in a bird's eye view mode.
