The VRS server is a GPS location information system operated by the National Geographic Information Service, and the location coordinate calculator 21 receives the location correction signal in real time with the VRS server using 4G and LTE communication methods. The position coordinate calculator 21 digitizes the precise position coordinates and the position correction signal, and calculates high-precision position coordinates using the digitized precise position coordinates and the position correction signal. In the case of soil sensors, since they are installed at very dense intervals, accurate location information of power facilities may not be calculated when the location coordinates calculated from the GPS module are used. In such a case, there may be a problem in that information is synthesized and displayed in the wrong location, so the location coordinate calculation unit 21 according to the embodiment collects information from the VRS server and calculates high-precision coordinates with an error smaller than the installation interval of the soil sensor. to make it usable.

In addition, the Kinect sensor may further include a pan/tilt unit for adjusting the angle of the microphone arrangement and the photographing unit 23 .

The basic principle of the Kinect sensor is that when a laser pattern irradiated from an infrared emitter is projected onto an object and reflected, the distance to the surface of the object is obtained using the position and size of the pattern at the reflection point. According to this principle, the photographing unit 23 may generate image data including depth information for each object by irradiating a laser pattern to an open-air vegetable garden and sensing the laser pattern reflected from the object.

The user interface unit 26 may receive various commands for operation of the augmented reality device 20 .

When the information on at least one plant growth factor is out of a preset threshold range, the control unit 27 may overlap the warning image on the composite image and display it on the display unit 25 . In this case, the display of the warning image may be performed by displaying an image including symbols, letters, numbers, figures, etc. or by changing the contrast, color, and saturation.

In addition, the control unit 27 may compare the plant growth factor information with a preset threshold range and display the difference value overlaid on the composite image. In this case, the difference value may be displayed in units of grams or percentages. Through this, the garden manager can specify the plant growth factors that fall short of the critical range and fertilize the soil by adjusting the amount by the difference value. In this case, the control unit 27 may convert the insufficient amount of the plant growth factor into a gram unit to reach the critical range and display the overlapped image on the composite image.

Also, the controller 27 may compare the plant growth factor information with a preset threshold range, update the difference value in real time, and display it on the composite image. When the plant growth factor information measured in the embodiment is less than a preset threshold range, the difference value may mean a difference value between the lower limit value of the critical range and the plant growth factor information. Also, when the measured plant growth factor information exceeds a preset threshold range, the difference value may mean a difference value between the upper limit value of the critical range and the plant growth factor information. Through this, the garden manager can grasp in real time whether the information on the plant growth factors through fertilization goes within the critical range, and can fertilize the soil with only an appropriate amount of the plant growth factors.
