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.
