Abstract: In the present disclosure, a structure of a 3-dimensional space measurement device is maximally simplified to be easily carriable by a user to measure a 3-dimensional spatial data. For simplifying the structure, a light transmission unit and a light reception unit are fixed to a support plate, and the support plate is fixed to a rotation unit. Provided are a 3-dimensional space measurement device capable of adjusting a rotation angle of the rotation unit and a tilt angle of the support plate to efficiently measure a distance and space, and a measurement method of a distance and space for making 3-dimensional spatial data.

Abstract: A laser distance measuring device and a control method for the same are disclosed. More specifically, disclosed herein are a laser distance measuring device capable of quickly measuring horizontal and vertical distances using laser and a control method for the same. The laser distance measuring device may include a light transmitter, a light receiver, a sensing unit, and a controller configured to perform an control operation to emit split laser through the light transmitter, acquire time difference information indicating a difference between a time to emit the split laser and a time to sense, through the sensing unit, the split laser reflected from a target position, and calculate a distance to the target position using the time difference information.
