Abstract: The system measures time of at least one object on the basis of passing a finish line and includes a camera with a photosensitive sensor and a lens for registering an image of the line. The image is sent to a processor for processing. Timing means deliver a timing signal to the processor. The system is at least partially automatically aligned. It thereto comprises a first active optical indicator that is located at a predefined location with reference to the line of passage, which indicator is detected as part of the image registered by the camera so as to obtain detection data. The system further includes a camera adjustment arrangement for adjustment of the orientation of a center axis of the camera, said adjustment being specified by the processor on the basis of the detection data.
