Method for changing a transport speed, at which a conveying apparatus (F-1, F-2) transports a number of objects (Ps-1, Ps-2, Ps-3), wherein a conveying apparatus (F-1, F-2) transports the objects (Ps-1, Ps-2, Ps-3) by means of at least one transport component (UF-1, UF-2), each transported object (Ps-1, Ps-2, Ps-3) rests on a transport component (UF-1, UF-2) of the conveying apparatus (F-1, F-2) during the transport, the speed at which the conveying apparatus (F-1, F-2) transports the objects (Ps-1, Ps-3, Ps-3) is adjusted to a target transport speed (v-target) at least once as a function of the result of a measuring step, and each measuring step is performed during the transport and comprises the steps that - during the transport, a number of recordings (Rec, Rec,...) of a section of the conveying apparatus (F-1, F-2) are generated one after the other in time such that - all recordings (Rec, Rec,...) in the same image recording direction are generated vertically or obliquely upwards and each object (Ps-1, Ps-2, Ps-3) is mapped on at least two recordings (Rec, Rec,...) and - each recording (Rec[i]) comprises a sequence of a number of recording components (B[i,1],...,B[i,N]) in each case, and - the recordings (Rec, Rec) are evaluated, characterised in that for each recording (Rec, Rec,...), the steps are performed that, - a check is carried out to determine whether this recording (Rec, Rec,...) shows at least one object, and - for each object shown in the recording (Rec[i]), at least one recording component (B[i,1],...,B[i,N]) of this recording (Rec[i]) which originates from this object, is selected in each case, for each recording (Rec[i]), the step is also performed that - for each first recording component (B[i,1],...,B[i,N]) of this recording (Rec[i]), which was selected as originating from an object, either at least a second recording component of a following recording in time is determined, which was likewise selected as originating from an object and which originates from the same object as the first recording component, or it is specified that such a second recording component is not present in any following recording, all selected recording components which originate from the same object in each case are determined and each object which is shown in at least one recording is measured by evaluating all selected recording components which were determined as originating from this object and the measuring result of the measuring step is used to calculate the target transport speed (v_target). - during the transport, a number of recordings (Rec, Rec,...) of a section of the conveying apparatus (F-1, F-2) are generated one after the other in time such that - all recordings (Rec, Rec,...) in the same image recording direction are generated vertically or obliquely upwards and each object (Ps-1, Ps-2, Ps-3) is mapped on at least two recordings (Rec, Rec,...) and - each recording (Rec[i]) comprises a sequence of a number of recording components (B[i,1],...,B[i,N]) in each case, and - the recordings (Rec, Rec) are evaluated, characterised in that - a check is carried out to determine whether this recording (Rec, Rec,...) shows at least one object, and - for each object shown in the recording (Rec[i]), at least one recording component (B[i,1],...,B[i,N]) of this recording (Rec[i]) which originates from this object, is selected in each case, - for each first recording component (B[i,1],...,B[i,N]) of this recording (Rec[i]), which was selected as originating from an object, either at least a second recording component of a following recording in time is determined, which was likewise selected as originating from an object and which originates from the same object as the first recording component, or it is specified that such a second recording component is not present in any following recording,
