  • Publication number: 20240094361
    Abstract: A fine section setting unit of a laser radar device sets, for a beat signal waveform indicating time change of a beat signal amplitude of an up beat signal, a plurality of fine sections within time ranges of the beat signal waveform. A fine section extraction unit extracts at least one fine section satisfying a preset extraction condition indicating that the beat signal amplitude in the fine section is high, from among the set plurality of fine sections. A peak detection unit subjects the beat signal in the extracted fine section to frequency analysis to calculate a fine section frequency spectrum and detect a peak frequency, which is a peak in the fine section frequency spectrum.

  • Patent number: 11724636
    Abstract: A combined radar and lighting unit includes a laser radar apparatus, a lighting device, and a controller. The laser radar apparatus is mounted to a vehicle, emits laser light toward an outside of the vehicle, and detects reflected light. The lighting device is mounted to the vehicle and emits visible light toward the outside of the vehicle. The controller controls the lighting device to cause the lighting device to alternately operate in a first emission mode to perform emission of the visible light, and in a second emission mode to stop emission of the visible light or reduce a quantity of the visible light. The controller controls the laser radar apparatus to interrupt the measurement of the distance while the lighting device is operating in the first emission mode, and executes the measurement of the distance while the lighting device is operating in the second emission mode.

  • Publication number: 20220075073
    Abstract: In a ranging device, a background light calculation unit calculates, for each of a plurality of bearing regions, a background light level parameter related to a level of background light arriving from the bearing region. A coefficient calculation unit calculates multiplier coefficients for the bearing regions such that the multiplier coefficient for each peripheral bearing region around a subject bearing region is negatively correlated with a difference in the background light level parameter between the subject bearing region and the peripheral bearing region. A coefficient-multiplied waveform generation unit generates, for each of the subject bearing region and the peripheral bearing regions, coefficient-multiplied waveform data acquired by multiplying ranging waveform data by the corresponding multiplier coefficient.
