Method for object recognition

A distance measuring system, comprising:

• a distance measuring unit;
• an electromagnetic radiation detector;
• and
• an evaluation unit, which is connected to the radiation detector and to which a detector signal of the radiation detector is thus delivered;
• wherein the distance measuring system is configured to carry out a method for recognizing an object located in an object space, the method comprising:
• emitting a distance measuring pulse into the object space by a signal time-of-flight based distance measuring unit;
• the object being provided with a marker which, in response to the influence of the distance measuring pulse, emits electromagnetic marker radiation in which object information for the object recognition is stored, recording the marker radiation by an electrical radiation detector and the object information for object recognition being assigned to the object;
• wherein the distance measuring unit emits the distance measuring pulse into the object space in the form of electromagnetic distance measuring radiation;
• wherein the evaluation unit is configured to read out the object information for object recognition from the detector signal and assign it to the object.

A component of a detergent, i.e. of a mixture for cleaning textiles, the component comprising:

• a marker configured for a method for recognizing an object located in an object space, the method comprising:
• emitting a distance measuring pulse into the object space by a signal time-of-flight based distance measuring unit;
• the object being provided with a marker which, in response to the influence of the distance measuring pulse, emits electromagnetic marker radiation in which object information for the object recognition is stored, recording the marker radiation by an electrical radiation detector and the object information for object recognition being assigned to the object;
• wherein the distance measuring unit emits the distance measuring pulse into the object space in the form of electromagnetic distance measuring radiation;
• wherein the marker is a passive marker which emits the marker radiation in response to excitation with the distance measuring radiation.
