Abstract
The present invention relates to a method for determining the extension of a trajectory in a space-time volume of measure images. The space-time volume of measure images is generated by a measuring method utilizing a measuring system comprising a first light source and a sensor. The measuring method comprises a step of, in a predetermined operating condition of the measuring system, moving a measure object along a first direction of movement in relation to the measuring system while the first light source illuminates the measure object whereby the sensor generates a measure image of the measure object at each time instant in a set of at least two subsequent time instants, thus generating said space-time volume of measure images wherein a feature point of the measure object maps to a trajectory in the space-time volume.
