Abstract: The present invention relates to a method for the three-dimensional detection of objects in which two images of a scene are detected and mutually corresponding objects in the images are identified by means of a correlation process. A binarization scheme which compares randomly selected point pairs with one another is used in the correlation process. The point pairs are fixed by means of a plurality of iterations.

Abstract: An optoelectronic apparatus for securing a source of danger in a spatial zone includes at least one image sensor that works in the infrared spectrum and that can generate range-resolved data of the spatial zone as well as an evaluation unit that is configured for the evaluation of the data for the detection of objects in a three-dimensional protected space within the spatial zone, wherein the source of danger is additionally at least partly secured by a mechanical partition that is at least very largely permeable to visually visible light. To provide a solution that prevents or at least reduces disturbing optical influences from outside the partition, it is proposed that the partition is coated with a layer such that the non-coated layer that is at least partly transparent for the image sensor is visible for the image sensor in a defined manner through the layer and is opaque.

Abstract: A method of securing at least one hazard zone comprising a hazardous machine is provided, wherein objects are detected in an environment of the hazard zone from measured data of at least one 3D sensor, and wherein a safety directed reaction of the machine takes place on an impending danger. A switch is made to at least one new hazard zone to be activated during the operation of the machine and a check is made whether the new hazard zone to be secured is free of objects.

Abstract: A safe optoelectronic sensor (10) is provided for securing a monitored zone (12) comprising at least one machine (26) that forms a hazard area (26a-b), wherein the sensor (10) has a light receiver (16a-b) for generating a received signal from received light from the monitored zone (12); a control and evaluation unit (24) for detecting object positions (28) in the monitored zone (12) from the received signal; and a safe output interface (30) for information acquired from the object positions (28). The control and evaluation unit (24) is here configured to determine the shortest distance between the hazard area (26a-b) and object positions (28) and to provide it at the safe output interface (30).

Abstract: The present invention relates to a method for the three-dimensional detection of objects, in which an image is detected and is compared to a known reference image and mutually corresponding objects in the images are identified by means of a correlation process. A binarization scheme is used in the correlation process and compares randomly selected point pairs to one another. The point pairs are fixed by means of a plurality of iterations.

Abstract: A method of transmitting image data in a safety sensor or in a safety system is provided, in which transmission errors are recognized in that meta information is added to the image data prior to the transmission and the meta information is checked after the transmission. The image data are here transmitted by an unsafe communication link, in particular a black channel, the meta information is prepended and/or appended to the image data and/or to the partial packets, and the meta information comprises a piece of information on the structure of the image data.

Abstract: An optoelectronic sensor for detecting objects in a monitored zone is provided having at least one light receiver for generating measurement data from received light from the monitored zone and having a safe evaluation unit that has at least two processing channels for a redundant processing of the measurement data and having a comparison unit for comparing processing results of the processing channels to uncover errors in a processing channel 30a-b. The processing channels are here each configured for a determination of a signature with respect to their processing results; and the comparator unit is configured for a comparison of the signatures.
