  • Publication number: 20250052898
    Abstract: A distance measurement apparatus (10) is an apparatus that causes a light receiving unit (180) to detect pulsed-light, which is emitted from a light source (14) and reflected by a target object (30). The distance measurement apparatus (10) includes an estimation unit (121). The estimation unit (121) estimates a peak position of the pulsed-light by using a saturation waveform that is a reception light waveform which is generated by the light receiving unit (180) that receives the pulsed-light and in which a reception light signal is partially saturated. Here, the estimation unit (121) specifies a temporary peak position by using a plurality of data points including a start point of the saturation in the saturation waveform. Further, the estimation unit (121) specifies a correction parameter based on a saturation width of the saturation waveform. The estimation unit 121 estimates the peak position of the pulsed-light by correcting the temporary peak position by using the specified correction parameter.

  • Publication number: 20250044430
    Abstract: A distance measurement apparatus (10) is a distance measurement apparatus (10) that emits pulsed-light emitted from a light source (14) through a transmissive member (20) and causes a light receiving unit (180) to detect the pulsed-light reflected by a target object (30). The distance measurement apparatus (10) includes a determination unit (121). The determination unit (121) performs at least one of a determination on whether or not an attached-matter exists at the transmissive member (20) and a determination on whether or not the target object (30) is at a short distance from the distance measurement apparatus (10), by using a saturation waveform. Here, the saturation waveform is a reception pulsed-light waveform which is generated by the light receiving unit (180) and in which a reception light signal is partially saturated.

  • Patent number: 12099143
    Abstract: An electromagnetic wave irradiated by an irradiator (10) is incident on and reflected by a movable reflection unit (20). The control unit (30) controls the irradiator (10) and the movable reflection unit (20). A sensor (40) is disposed at a position through which the electromagnetic wave when an irradiation direction of the electromagnetic wave is moved in a first direction. Then, the control unit (30) executes the following processing in setting a movement range of the movable reflection unit (20). First, a detection value (first detection value) of the sensor (40) when light is irradiated at a first position Sa positioned ahead of the sensor (40) in the first direction is recognized. Next, a detection value (second detection value) of the sensor (40) when light is irradiated at a second position Sb positioned behind the sensor (40) in the first direction is recognized. Then, the movement range of the movable reflection unit (20) is set using the first detection value and the second detection value.

  • Publication number: 20190265357
    Abstract: An electromagnetic wave from a transmitter (100) is emitted toward the outside of a first angular range (AR). A receiver (200) cannot detect an electromagnetic wave reflected at a position somewhat close to a sensor device (10), specifically, an electromagnetic wave reflected at a position apart from the sensor device (10) by less than a distance R1. Specifically, when the electromagnetic wave is reflected at the position apart from the sensor device (10) by less than the distance R1, the electromagnetic wave reaches the sensor device (10) before the first angular range (AR) reaches a Y axis. Consequently, the electromagnetic wave reflected at the position somewhat close to the sensor device (10) is not detected by the receiver (200).
