  • Patent number: 10837759
    Abstract: A three-dimensional measuring device includes a human detection information receiver for receiving information from a human detection sensor that detects a person present within a detection range, a laser emitter for irradiating a region including the object with the laser beam, a laser emission controller for controlling power of the laser beam irradiated from the laser emitter to first power and second power lower than the first power, an image capturing device for imaging the object, on which the laser beam is irradiated, and acquiring image data, and a point-group-data generator for generating, based on the image data, three-dimensional point group data of a region including the object. When the human detection information receiver receives, from the human detection sensor, first information indicating that a person is absent from the detection range, the laser emission controller controls the power of the laser beam to the first power.
