Abstract
The invention relates to a method and a measuring system for measuring a movable object, for example a lateral guide on the transport path of a casting strand in a metallurgical installation. The system has at least one light source (110) for emitting parallel light beams (130) and a receiving device (120) with a sensor field for receiving the light beams. An evaluation device is used to evaluate the light beams received by the sensor field. In order to be able to make the evaluation simpler and faster, the receiving device is designed to generate an image of the sensor field having the positions of the sensors of the sensor field, which are assigned to the light beams not influenced by the object, and having the positions of the sensors of the sensor field, which are assigned to the light beams which are emitted, but are influenced by the object. The distances between the individual sensors are likewise known on the basis of the known resolution of the sensor field. The evaluation device is designed to evaluate the image with regard to the depth of penetration of the object into the spatial area spanned by the light beams, the speed and/or the contour of the object (200).
