  • Publication number: 20240264272
    Abstract: According to an example aspect of the present invention, there is provided a method comprising, determining an initial set of measurement results, wherein said initial set of measurements results comprises at least angles-of-arrivals and phases of initial reflected signals, the initial reflected signals being reflections of initial signals transmitted by a radar in a field of view of the radar, determining a phase map of the field of view of the radar, wherein the phase map comprises at least phase differences between the initial transmitted signals and the initial reflected signals as a function of said angles-of-arrivals of the initial reflected signals and determining a vibration map of the field of view of the radar based at least on the phase map.

  • Publication number: 20230036450
    Abstract: According to an example aspect of the present invention, there is provided a method comprising, receiving, from a radar, a first reflected signal and a second reflected signal, determining a reference signal of the first reflected signal and training an artificial neural network using the first reflected signal and the reference signal of the first reflected signal, upon training, determining an output of the artificial neural network associated with the first reflected signal and providing a magnitude and angle image of the radar associated with the second reflected signal based on the output of the artificial neural network associated with the first reflected signal.

  • Patent number: 10705217
    Abstract: An apparatus for controlling a plurality of imaging sensor nodes producing 3D structure of a scene is provided. The apparatus receives (500) location data from the sensor nodes, the location data indicating the locations of the moving objects, compares (502) the location data received from different sensor nodes at the same time instants with each other and determines (504) which detections of different sensor nodes relate to same moving objects. The apparatus further maps (600) the location data received from different sensor nodes to a common coordinate system and determines (602) the relationships of the fields of view of the sensor nodes with each other and the location data mapped to the common coordinate system.

  • Publication number: 20190164297
    Abstract: A method and an apparatus for controlling a system having one or more depth cameras is provided. The solution comprises receiving (402) a control signal from at least one sensor arranged to detect movement in the field of view of at least one depth camera and controlling (404) the operation of the camera system on the basis of the control sensor.
