Abstract: A three-dimensional (3D) face recognition system includes a structured light sensor or stereo camera sensor. The 3D face recognition system also includes a time-of-flight sensor. The 3D face recognition system further includes a processor. The processor is configured to run algorithms for face recognition on data from the structured light sensor or stereo camera sensor. The processor is also configured to use distance data from the time-of-flight sensor to optimise the algorithms for face recognition.

Abstract: An optoelectronic sensor for a time-of-flight (ToF) measurement includes a light projector, a light receiver, a receiver logic, and a processing unit. The light receiver includes a number of macro-pixels. The receiver logic is operable to generate light ToF data for the respective macro-pixels corresponding to a number of time windows. The processing unit selects an initial set of integration times that defines an integration time for each time window and macro-pixel and acquires an initial frame of ToF data by collecting ToF generated from the macro-pixels according to the time windows and integration times defined in the initial set of integration times. The processing unit also computes a metric from the initial frame of ToF data. The metric is indicative of a data quality generated by the respective macro-pixels.

Abstract: A LIDAR system includes a laser device configured to emit a transmit signal towards an object. A frequency of the transmit signal is variable by varying a current injected in the laser device. The LIDAR system also includes a laser driving system for driving the laser device. The LIDAR system further includes a receiver configured to receive an input signal. The input signal is based on a superposition of the transmit signal and a reflected signal reflected by the object. The laser driving system is configured to supply the current having an intensity varying in accordance with a combination at different timings of a changing frequency of the transmit signal with time and a constant frequency with time. A speed and a distance between the object and the receiver are configured to be determined from the input signal.
