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.

Distance measuring device and method thereof

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.

Three-dimensional space measurement device and method for operating same

The present invention relates to an apparatus for measuring a distance, the apparatus including a light transmitter including a light source configured to emit a light, and a collimator lens configured to emit a light by converting the light emitted from the light source to a collimation light, and a light receiver including a first mirror configured to reflect the collimation light emitted from the collimator lens to an object, a lens configured to concentrate a light reflected or dispersed from the object to a spot, and a photo-detector configured to form a spot concentrated with light on the lens, wherein an optical axis of the light source matches a rotation shaft of the photo-detector, the light transmitter is fixed and the light receiver rotates about the optical axis of the light source.

Apparatus for measuring distance

The present invention relates to a distance measurement apparatus. The distance measurement apparatus according to the present invention has, mounted thereon, a light transmitting portion which emits light, and a light receiving portion including a light receiving element where a spot of the light is collimated. The present invention comprises: a tilting base; and a rotating reflector which reflects the light emitted by the light transmitting portion to an object, and reflects the light reflected or scattered by the object to the light receiving portion.
