The present invention relates to an arrangement for determining the positions of a plurality of measuring points on an object, such as an automotive vehicle, these measuring points being moveable in relation to a reference point. According to the invention, an optical signal emitter (11-1n) is arranged at each measuring point. These signal emitters function to produce, in sequence, an optical pulse of short duration, which is delivered to a computer (3) through the intermediary of an optical receiver means (2), which produces an output signal representative of the position of the signal emitter concerned. The signals are identified in the computer on the basis of the time point at which they were produced. The positions of the measuring points are also calculated by the computer and displayed on a display device (4), for instance a display screen. This measuring arrangement enables several measuring points to be monitored at one and the same time, therewith enabling a total picture of the deformation of an object to be readily obtained. The invention also relates to a method for determining the positions of a plurality of measuring points on an object, these measuring points being moveable in relation to a reference point. |
