Abstract
A method to determine the dimensions and distance of a number of objects in an environment includes providing a number of objects including a marking element; recording a visual image-dataset of at least one of the objects with a camera; and determining a parameter value from the image of a marking element in the image-dataset or from a measurement of an additional sensor at the location of the camera. The parameter value is a value depending from the distance of the object to the camera. The method further includes calculating the relative distance between the object and the camera based on the parameter value and calculating dimensions of the object from at least a part of the image of the object in the image-dataset and the calculated distance. A related device, a related system and a related control unit for a virtual reality system are also disclosed.
