ABSTRACT:
The invention relates to a method and to an apparatus for the detection of objects moved on a segmented conveyor means by means of an optoelectronic sensor, in which in each case the geometric center of the objects is determined via the optoelectronic sensor, whereupon the objects are each associated with that conveyor segment in the region of which the respectively determined geometric center is located. The invention further relates to a method and to an apparatus for the determination of the dimensions of objects moved on a conveyor means by means of an optoelectronic sensor, in which the dimensions of the objects are detected and corresponding. object-related values are supplied, and in which the optoelectronic sensor additionally also detects the dimensions of the conveyor means and supplies corresponding, conveyor means-related values, with conveyor means tolerances and/or hollow spaces possibly present between the object and the conveyor means being compensated by an offsetting of the object-related values with the conveyor means-related values.
