    摘要: Disclosed is imaging system (200) including controllable light source; image sensor; metalens to focus light onto IS; and processor(s). The processor(s) is configured to control CLS to illuminate given part of field of view of IS at a first instant, while controlling IS to capture first image (FImg). The image segment(s) represent a given part as illuminated and remaining image segment(s) represent a remaining part of the FOV as non-illuminated. The processor controls the CLS to illuminate the remaining part at second instant, while controlling IS to capture a second image whose image segment(s) represents a given part as non-illuminated and a remaining image segment(s) represents a remaining part as illuminated. Output image is generated based on: (i) image segment(s) of FImg and remaining image segment(s) of SImg, and/or (ii) remaining image segment(s) of FImg and image segment(s) of SImg.

    摘要: A light detection and ranging (LIDAR) system for a vehicle, includes a laser source configured to generate light signals, a transceiver, and a fiber array coupled to the transceiver and including a plurality of output channels. The transceiver is configured to receive one or more light signals from the laser source through a first group of output channels of the fiber array, receive one or more local oscillator (LO) signals through a second group of output channels of the fiber array, transmit the one or more light signals into an environment of the vehicle, receive a first returned light reflected from one or more objects in the environment, and output the first returned light and a first LO signal of the one or more LO signals.

    摘要: A hand-held observation device includes: a laser rangefinder (LRF) unit configured to measure a distance between the observation device and a target point on a remote target, a camera configured to capture images of the target, a pose detection unit configured to detect a pose of the observation device, a display unit configured to display an image of the target, a user input device and a digital processing unit comprising a memory for storing program data and measurement data. The digital processing unit can receive a measurement request from the user, can receive image data from the camera, can continuously receive pose data from the pose detection unit, can trigger range measurements to target points using the LRF unit, can receive range-measurement data from the LRF unit, can calculate 3D target point coordinates for the target points, can store the 3D target point coordinates in the memory, can compare the stored 3D target point coordinates with the measurement request to determine one or more regions with missing 3D target points coordinates, can continuously-monitor the pose of the observation device based on the pose data, can detect when the measurement axis of the LRF unit aims at a region with missing 3D target point coordinates, and can trigger an additional range measurement for measuring 3D target point coordinates.

    摘要: An object detection device includes an acquisition module and a detection module. The acquisition module acquires a detection distance indicating a distance from a transmission/reception unit mounted on a vehicle to an object and a reception intensity indicating an intensity of a reflected wave received by the transmission/reception unit. The detection distance is detected based on results of transmission of a transmission wave by the transmission/reception unit and reception of the reflected wave from the object by the transmission/reception unit. The detection module detects a detection target among objects including the object based on the reception intensity exceeding an intensity threshold. The detection module increases the intensity threshold when the detection distance is a distance threshold or less and the detection target is detected.

    摘要: A decoupling element for an ultrasonic sensor is disclosed. The ultrasonic sensor is able to be attached to a flat component for a vehicle. The flat component includes a cutout. The ultrasonic sensor includes a cylindrical ultrasonic transceiver element which is able to be introduced into the cutout. The decoupling element includes a hollow-cylindrical element for enclosing the cylindrical ultrasonic transceiver element of the ultrasonic sensor and a plurality of support ribs which are arranged in the radial direction outside the hollow-cylindrical element and are spaced apart from one another in a circumferential direction of the hollow-cylindrical element for supporting the decoupling element on a region of the flat component outside the cutout when the cylindrical ultrasonic transceiver element with the hollow-cylindrical element enclosing it is introduced by an end portion at an axial end into the cutout.
