  • Patent number: 10657392
    Abstract: The purpose of the present invention is to improve the speed of processing related to the presence of objects, while maintaining measurement accuracy of object detection, in an object detection device. This object detection device is provided with: an output unit; a plurality of detection units; a first data generation unit; a second data generation unit; and an information processing unit. The output unit outputs measurement light. The plurality of detection units detect reflected light. The first data generation unit generates first data. The second data generation unit generates second data by extracting, from the first data, a plurality of pieces of second position information, which are pieces of first position information that correspond to representative points expressing the presence ranges of objects. The information processing unit uses the second data to execute information processing related to the presence of the objects.

  • Patent number: 10656270
    Abstract: This object detection device is provided with: an output unit; a plurality of detection units; a data acquisition unit; and an object information confirmation unit. The output unit outputs measurement light Lm towards an object. Each of the plurality of detection units detects, as a signal representing the distance to the object present in an observed area and the shape of the object, the reflected light generated as a result of the measurement light being reflected by the object. The data acquisition unit acquires detection signal waveforms W representing changes in the intensities of second signals over time. The object information confirmation unit confirms the range of the presence of the object by determining that any two or more of the detection units correspond to the same object, or correspond to different objects, on the basis of the detection signal waveforms.
