Abstract: A device for monitoring the door area around a that is at least partially glazed door is provided. A transmitter emits a transmission pulse of electromagnetic radiation. An image recorder comprises a receiver matrix having a first receiver blocks which has a plurality of first receivers. The first receivers receive reflected signal components of the transmission pulse. Each first receiver has a memory unit which is designed to integrate and store the reflected signal components received. A control unit triggers a transmission pulse of the transmitter and activates the first receivers for a predetermined first receiving period. An evaluation unit compares topography image data with stored reference image data or compares a respective distance value with a stored reference value for a door area free of objects.

Abstract: A registration system for classifying an object, comprising a sensor unit, an evaluation unit, a memory unit and a data-processing unit. The evaluation unit determines a structure data set or a temporal sequence of structure data sets of the object to be registered from a temporal progression of the radiation captured by the sensor assembly. The memory unit stores association rules, each associated with a set of situation parameters. The data-processing unit accesses the structure data set or a temporal sequence of structure data sets, the current situation parameter set, and the association rule associated with the current parameter set and to associate an object with an object class on the basis of the structure data set associated with the object or a temporal sequence of structure data sets by using an association rule associated with the current situation parameter set and received from the memory unit.

Abstract: The invention relates to a device for monitoring the door area of an at least partially glazed door. The device comprises a transmitter, an image recorder, a control unit, and an evaluation unit. The transmitter is used to emit at least one transmission pulse of electromagnetic radiation. The image recorder comprises a receiver matrix having at least one first receiver block, which has a plurality of first receivers. The first receivers of the first receiver block are designed and arranged in such a way that they receive reflected signal components of the transmission pulse in a second predetermined distance range of an outer region of the door area, the distance range being determined in relation to the door. Each first receiver has a memory unit which is designed to integrate and store the reflected signal components received.
