A robotic working tool comprising a sensor for detecting magnetic fields connected to a controller for controlling the operation of the robotic working tool. The controller is configured to operate according to a first control signal being transmitted through a first boundary wire and according to a second control signal being transmitted through a second boundary wire. The robotic working tool is thereby configured to operate within a composite work area comprising at least a first partial work area and a second partial work area. The first boundary wire delimits the first partial work area and the second boundary wire delimits the second partial work area. The at least first and second boundary wires provide a common perimeter for the composite work area. Analysing the magnetic fields detected by the sensor, the controller determines whether the robotic working tool is inside or outside the composite work area.

The present disclosure relates to an outdoor robotic work tool () adapted for a forward travelling direction (D) and comprising an environmental detection system () that comprises a set of outer detector transceivers () and a set of inner detector transceivers (), where the inner detector transceivers () are positioned between the outer detector transceivers (). Each detector transceiver () is adapted to transmit signals () and to receive reflected signals () that have been reflected by an object (). The outer detector transceivers () are associated with outer coverage main directions () that are directed at corresponding outer angles (&#x3b1;, &#x3b1;) to the forward travelling direction (D), and the inner detector transceivers () are associated with inner coverage main directions () that are directed at corresponding inner angles (&#x3b2;, &#x3b2;) to the forward travelling direction (D). The inner angles (&#x3b2;, &#x3b2;) have magnitudes that exceed the magnitudes of the outer angles (&#x3b1;, &#x3b1;), and the inner coverage main directions () intersect in front of the outdoor robotic work tool () in the forward travelling direction (D).

The present disclosure relates to a method of controlling a traffic surveillance system. The method comprises the steps of: capturing first images and second images over time by a plurality of the stereoscopic sensors; processing, by the processing unit, a first image and a second image from a first stereoscopic sensor of the plurality of the stereoscopic sensors to produce a first height image; analyzing said first height image to detect a moving object such as a vehicle located within the primary view; and analysing a part of a primary view of at least a first image, a second image or a combination of the first image and the second image captured by a second stereoscopic sensor based on the detected moving object in said first height image to determine a characteristic of the moving object.
