Measurement of a dimension on a surface

The invention relates to a device, to a vehicle (1), and to a method for measuring a dimension between at least two points on surfaces. The device comprises: at least one image-producing device (4, 7, 10, 12) for scanning the vehicle environment, a display device (8) for displaying the representation of the vehicle environment, an input device (9) for defining at least two points as measurement points, between which the dimensions should be determined, in the displayed representation, at least one environment sensor (7, 10, 12, 13) for sensing the distance and the direction of the measurement points with respect to the vehicle (1), and an evaluating device (3) for determining the dimension on the basis of the sensed distances and directions of the measurement points and for outputting the determined dimension. 本发明涉及用于测量表面上的至少两个点之间的尺寸的装置、车辆(1)和方法。在此所述装置具有：-用于扫描车辆环境的至少个成像器件(4、7、10、12)，-用于显示车辆环境的映像的显示器件(8)，-用于在显示的映像中确定至少两个点作为测量点的输入器件(9)，在所述测量点之间要确定尺寸，-至少个环境传感器(7、10、12、13)，其用于检测测量点关于车辆(1)的距离和方向以及-评估器件(3)，其用于借助测量点
