  • DEVICE AND METHOD FOR MEASURING DISTANCE USING LASER
    Publication number: 20220244382
    Abstract: A distance measuring device and a distance measuring method using a laser are disclosed. The distance measuring device includes a laser module that emits a laser to a target point spaced apart from the distance measuring device, and detects a laser reflected from the target point, an acceleration sensor that measures an acceleration of the distance measuring device and outputs an acceleration signal, a gyro sensor that measures an angular velocity of the distance measuring device and outputs an angular velocity signal, and a microprocessor that calculates a distance between target points using acceleration information related to the acceleration signal, angular velocity information related to the angular velocity signal, and information related to the laser.
