The present disclosure relates to various embodiments of an optical component for a LIDAR Sensor System. The optical component may include an optical element having a first main surface and a second main surface opposite to the first main surface, a first lens array formed on the first main surface, and/or a second lens array formed on the second main surface. The optical element has a curved shape in a first direction of the LIDAR Sensor System.

An image signal indicative of the head pose of a person in a scene, as provided by a camera may be processed by estimating, as a function of the image signal received by the image sensor, the head pose of the person. A view frustum of the person may be generated from the estimated head pose. A visual frustum of attention or VFOA of the person may be generated from the view frustum. From the visual frustum, a predicted movement trajectory of the person or an estimated scene attention map as a function of the visual frustum of attention, preferably by identifying in the attention map at least one object to be controlled may be generated.

Method of view frustum detection and a corresponding system and product

The presence of a stationary object is to be reliably recognized. Thereto, a presence detection device for detecting a presence of an object in its environment is provided, which comprises a movement detection unit for detecting an initial movement of the object in the environment of the presence detection device and for outputting a movement signal depending on the detection as well as a control unit for generating an activation signal depending on the movement signal. Moreover, the presence detection device comprises a camera, which can be activated by the activation signal, for obtaining a video signal of the environment of the presence detection device and an evaluation unit for generating a presence signal relating to the presence of the object by evaluating the video signal.

Detection of the presence of static objects

A lighting system including a set of lighting devices for lighting an environment that may be controlled by a method. The method may include receiving, from one or more image sensors (e.g. a RGB-D camera&#x2014;W), an image signal including a sequence of images of the environment under different conditions of illumination and light reflection. The method may further include processing the image signal to provide a light source identification signal representative of light sources affecting the environment, and controlling the lighting devices as a function of the light source identification signal, and, possibly, of human occupancy and activity.

Method of identifying light sources and a corresponding system and product

A method for image processing is disclosed. A non-normalized cross correlation is used to produce a cross correlation matrix between a recorded image, which contains at least one captured object, and a reference image, which contains a reference object. A comparison between a plurality of regions of the correlation matrix is carried out for a respectively captured object. A decision as to whether the respectively captured object and the reference object correspond is made on the basis of a result of the comparison. The non-normalized cross correlation is carried out by means of the equation CCdenotes a point or a matrix element of a cross correlation matrix or of a 'correlogram' CC, Imgdenotes a pixel (i, j) of a recorded matrix-shaped image Img and Tdenotes a pixel (k,l) of a matrix-shaped reference image or reference template T with (NTx&#xb7;NTY) pixels, which contains a reference object.
