    摘要: A laser radar device includes a transmission unit, a scanning unit, a distance calculation section, and a movement control unit. The transmission unit transmits laser light that has been subjected to frequency modulation. The scanning unit performs scanning with the laser light. For each of a plurality of partial regions obtained by dividing a laser light scanning region preset as a two-dimensional region which the scanning unit scans with the laser light, the distance calculation section receives the laser light that has been reflected by an object, and calculates a distance to the object in the partial region. The movement control unit controls movement of the laser light so that the laser light moves in the partial region, with Δθ>(1.22*λ/d) being met.

    摘要: An optoelectronic sensor for the detection of objects in a monitored zone is provided that has a light transmitter for transmitting a light beam, a light receiver for generating a received signal from the light beam remitted by the objects in the monitored zone, a control and evaluation unit for the detection of information on the objects with reference to the received signal, a base unit, a scanning unit movable with respect to the base unit for the periodic scanning of the monitored zone, and a drive having a hollow shaft for moving the scanning unit, wherein the scanning unit comprises a first data transmission unit and the base unit comprises a second data transmission unit to exchange data wirelessly between the base unit and the scanning unit through the hollow shaft, The first data transmission unit and the second data transmission unit are configured as microwave units for the data exchange by means of microwave signals.

    摘要: A method for measuring a given distance between a vehicle and an upper surface of a platform includes projecting two or more beams by a detection system mounted on the vehicle. The beams lie in a single plane of projection towards the platform. For each beam, a distance is measured between the detection system and the platform along a respective direction of the beam. The measured distances not corresponding to the upper surface are excluded. A vertical distance between a vehicle marker and the upper surface of the platform is calculated from the distances that are not excluded.

    摘要: Systems and methods are provided that include a plurality of sensors, communicatively coupled to one another, to periodically transmit positional location information. A digital image capture device, communicatively coupled to the plurality of sensors, may capture an image of a scene which includes at least one of the plurality of sensors. A processor, communicatively coupled to the digital capture device, may determine a measurement of a least one object in the captured image of the scene, where the measurement of the at least one object is based at least in part on the positional location information received by the digital image capture device at the time that the image of the scene is captured. A display device, communicatively coupled to the processor, may display the determined measurements of the at least one object.
