Abstract: A system is provided for protecting a computer system and/or control system against manipulation and functional anomalies. The system includes a monitoring module, which has at least a first interface, a second interface, and at least one memory. The system is configured to receive information characterizing the system state of the computer system and/or control system via the first interface, receive an encrypted request for system state via the second interface and decrypt it using a request key stored in the memory, and generate a response to the request from at least a portion of the information received via the first interface. The system is also configured to encrypt the response with a response key determined using the request and output it via the second interface, determine a new request key which is a shared secret also accessible to the sender of the request, and store this new request key in the memory.

Abstract: A feature point detection apparatus for detecting feature points in image data includes an image data providing unit for providing the image data, a key point determination unit for determining key points in the image data, a feature determination unit for determining features associated with the key points, each describing a local environment of a key point in the image data, and a feature point providing unit for providing the feature points. A feature point is represented by the position of a key point in the image data and the associated features. The image data comprise intensity data and associated depth data, and the determination of the key points and the associated features is based on a local analysis of the image data in dependence on both the intensity data and the depth data.

Abstract: A system and method are provided for monitoring the operational status of a computer system and/or control system. The method includes detecting at least one time-variable signal in the computer system and/or control system and forwarding it to a hardware module operating independently of the computer system and/or control system. The method also includes forming a summary statistics of the signal by the hardware module over a predetermined period of time and checking an extent of the summary statistics relative to a normal state and/or nominal state of the computer system and/or control system. The method also includes evaluating an operating state of the computer system and/or control system based on the checking.

Abstract: A system for processing measured 3D values of a scene is described. The 3D measurement values comprise first 3D measurement values acquired from a first perspective and second 3D measurement values acquired from a second perspective different from the first perspective. The fields of view of the first perspective and the second perspective are at least partially overlapping. The 3D measurement values have been acquired by one or more 3D measurement devices. The system comprises one or more processing units for multi-stage processing of the 3D measurement values using a hierarchical location uncertainty model which takes into account various measurement errors of the 3D measurement values and/or boundary conditions for the 3D measurement values, which are dependent on the geometry of the scene and the first perspective and/or the second perspective.
