Abstract: A testing apparatus and a testing method for a traffic monitoring device with a laser scanner. The testing apparatus has an adjusting plate which provides a receiving place for receiving a traffic monitoring device which is to be tested and a measuring board. A line pattern along an imaginary straight line extending at the height of the reference scanning plane is provided on the measuring board which has a matte black surface. Vertical lines and a diagonal line are arranged on the straight line, and the diagonal line forms an angle with the straight line, which angle is selected in such a way that laser pulses emitted by the laser scanner form at least three laser spots with a reference laser spot width and a reference laser spot length on the diagonal line.

Abstract: A method for detecting and evaluating a plane for recognition of an object includes detecting the object using a sensor disposed on a vehicle, the object being present in a direction of a relative direction of movement of the vehicle and the sensor being directed onto the plane. A distance of the sensor from at least one measuring point is determined using a control unit. A value of the determined distance is compared with a reference value so as to obtain a difference value. The difference value is delivered to an evaluation unit as at least one of an object, an obstacle, a hole, a floating particle, a defect in the plane and a measurement error.
