The invention proposes a method for determining a number (13) of transfer objects which are moving from a first subregion (8) of an observed region (5) into a second subregion (9) of the observed region (5), wherein a succession of images of the observed region (5) is recorded which identify objects (1; 2; 3; 4) and determine positions (1b, 1c; 2a, 2b, 2c; 3a, 3b, 3c; 4a, 4b) for the objects (1; 2; 3; 4), respectively, the objects (1; 2; 3; 4) are each associated either with the first subregion (8) or with the second subregion (9) on the basis of the positions (1b, 1c; 2a, 2b, 2c; 3a, 3b, 3c; 4a, 4b) of said objects, and multiple transfers of the same object between the first subregion (8) and the second subregion (9) are taken into account when determining the number (13) of transfer objects. The invention likewise proposes an appropriate system which can be used to carry out the method, said system comprising a sensor arrangement and a computation unit connected to the sensor arrangement.
