## Abstract

A device according to embodiments may calculate a measurement value according to a measurement mode on the basis of the inclination of a laser range finding apparatus. A storage medium according to embodiments stores at least one program configured to be executed by one or more processors of a finding device which is communicable with a laser range finding apparatus and includes a display, the program calculating a measurement value according to a measurement mode on the basis of the inclination of the laser range finding apparatus. A laser range finding apparatus according to the embodiments may calculate the distance between the laser range finding apparatus and at least one object on the basis of the inclination of the laser range finding apparatus.

## Claims

### Claim 1

A measurement device capable of communicating with a laser range finding apparatus, the measurement device comprising:
a display unit;
one or more processors; and
a memory, wherein:
the device is allowed to communicate with the laser range finding apparatus, the memory comprises at least one program executed by the one or more processors, and the at least one program comprises one or more instructions, and
the one or more instructions are configured to:
display, on the display unit, alarm information indicating that an inclination of the laser range finding apparatus is less than a preset value when the inclination of the laser range finding apparatus is less than the preset value;
display a user interface for operation of the laser range finding apparatus on the display unit; and
select any one of a plurality of measurement modes including a one-way range finding mode, a two-way range finding mode, an area measurement mode, and a volume measurement mode, and calculate a value according to the selected measurement mode based on a distance between the laser range finding apparatus and at least one object measured based on a time at which an output laser beam is received or a phase thereof and the inclination of the laser range finding apparatus according to a user input signal commanding output of the laser beam from at least one of a first laser module or a second laser module included in the laser range finding apparatus according to the selected measurement mode.

### Claim 2

A recording medium storing at least one program configured to be executed by one or more processors of a measurement device allowed to communicate with a laser range finding apparatus and comprising a display unit, the at least one program comprising one or more instructions configured to:
display, on the display unit, alarm information indicating that an inclination of the laser range finding apparatus is less than a preset value when the inclination of the laser range finding apparatus is less than the preset value;
display a user interface for operation of the laser range finding apparatus on the display unit; and
select any one of a plurality of measurement modes including a one-way range finding mode, a two-way range finding mode, an area measurement mode, and a volume measurement mode, and calculate a value according to the selected measurement mode based on a distance between the laser range finding apparatus and at least one object measured based on a time at which an output laser beam is received or a phase thereof and the inclination of the laser range finding apparatus according to a user input signal commanding output of the laser beam from at least one of a first laser module or a second laser module included in the laser range finding apparatus according to the selected measurement mode.

### Claim 3

A laser range finding apparatus comprising:
a body;
a first laser module and a second laser module located at both ends along a vertical axis of the body, the first laser module outputting a first laser beam, the second laser module outputting a second laser beam in a direction opposite to the first laser module;
a sensor unit included in the body, the sensor unit securing an inclination of the laser range finding apparatus;
a display unit located on a surface of the body; and
a controller included in the body,
wherein the controller determines whether the secured inclination is less than a preset value, generates an alarm indicating that the secured inclination is less than the preset value, performs a control operation so that a laser beam is output from at least one of the first laser module or the second laser module, and calculates a distance between the laser range finding apparatus and at least one object based on a time at which the output laser beam is received or a phase change of the output laser beam and the secured inclination.
