Referring to FIG. 1 , an optical information measuring system for each region according to an embodiment of the present invention may include a region setting device 10 and a mobile optical information measuring device 20 .

The area setting device 10 is formed to set a plurality of optical information measurement areas by using a plurality of sensors 31 formed to distinguish areas. The light information measurement space 30 may be part or all of an indoor space in which a user intends to measure light information. The area setting device 10 may set an optical information measurement area by installing a plurality of sensors 31 in the optical information measurement space 30 . In one embodiment of the present invention of FIGS. 1 to 4 , it is described that optical information is measured for all of the optical information measuring space 30 for convenience of description.

The area setting device 10 is formed to include an area standard setting unit 110, a measurement area setting unit 120, and a measurement area information generating unit 130 as shown in FIG. 2 to set an optical information measurement area. It can be.

The region standard setting unit 110 is configured to obtain measurement information using the sensor 31 and set a region standard using the obtained measurement information. The area setting device 10 may be configured to install a plurality of sensors 31 in an optical information measurement space, which is a space in which optical information is to be measured. At this time, the area standard setting unit 110 may set the entire optical information measurement area 30 using a line connecting the outermost peripheries of the installed sensors.

When the area standard setting unit 110 sets the entire optical information measurement area 30, the partial optical information measurement area 32 is set using a plurality of sensors 31 installed in the entire optical information measurement area 30. Area reference information, which is a criterion for doing so, is acquired. Hereinafter, for convenience of description, the partial optical information measurement region 32 will be referred to as an optical information measurement region.

The area reference setting unit 110 may obtain measurement information from the plurality of sensors 31 to obtain area reference information for setting the partial light information measurement area 32 . Here, the measurement information may vary according to the type of sensor 31 .

For example, when the sensor 31 is the position measurement sensor 31, the region reference setting unit 110 may acquire the position of the sensor as measurement information. Through this, the region reference setting unit 110 may set a region reference using the positional information of the plurality of sensors 31 as one-dimensional measurement information and transmit it to the measurement region setting unit 120 to be described later.

Also, as another example, when the sensor 31 is the distance measurement sensor 31, the area reference setting unit 11 may obtain the position of the sensor acquired by the sensor 31 and the measured distance as measurement information. Through this, the region standard setting unit 110 may set a region standard using the location information and distance information of the plurality of sensors 31 as 2D measurement information and transmit it to the measurement region setting unit 120 to be described later.

The measurement area setting unit 120 may set a polygonal area having a plurality of sides using the area criterion transmitted from the area standard setting unit 110 and set the set polygonal area as the optical information measurement area. When the standard of the optical information measurement area is determined, the measurement area setting unit 120 sets a plurality of polygonal areas using the area standard to create the optical information measurement area 32 according to the standard.

Here, when the 1D measurement information is obtained, the measurement area setting unit 120 may set the measurement area using the 1D measurement information. The 1D measurement information includes the positions of the sensors 31 . Accordingly, the measurement area setting unit 120 may check only information of a specific location. Using this, the measurement area setting unit 120 may generate a plurality of polygonal areas by setting the location of the sensor 31 as a vertex of the polygon.

In addition, if the measurement area setting unit 120 acquires the 2D measurement information, it can set the optical information measurement area 32 using the 2D measurement information. The 2D measurement information includes not only the position of the sensor 31 but also the distance measured by the sensor. Here, the distance may be a distance to a wall, a distance to another sensor, or a distance to an object loaded in the space. The measurement area setting unit 120 may obtain a specific location and a distance measured from the specific location to the specific place using the 2D measurement information. Using this, the measurement area setting unit 120 may create a plurality of polygonal areas by using a line generated using the position and distance of the sensor 31 as one side of the polygon.

Here, the measurement region setting unit 120 can easily set the optical information measurement region when a plurality of sensors 31 are sprayed and installed throughout the optical information measurement space as shown in FIG. ) is installed, it is difficult to easily obtain the optical information measurement area as shown in FIG. Accordingly, the measurement region setting unit 120 may create a virtual 2D plane and project 2D measurement information onto the created 2D plane to create a plurality of optical information measurement regions. For example, the measurement area setting unit 120 marks the positions of the sensors 31 on a two-dimensional plane and generates extension lines of electromagnetic waves emitted from the sensors from the marked positions. Then, the measurement area setting unit 120 may set a polygonal area generated by using each extension line as one side as an optical information measurement area.

In FIG. 1 , for convenience of explanation, it has been described that the optical information measuring regions 32 of the present invention are all rectangular, but the present invention is not limited thereto. The shape of the polygon generated by the measurement area setting unit 120 may be changed according to a user's setting, and preferably may be a rectangle as shown in FIG. 1, but the shape may be changed as needed.

The measurement area information generation unit 130 is configured to generate measurement area information representing an optical information measurement area. Here, the measurement region information may be information for distinguishing and recognizing a plurality of optical information measurement regions set by the measurement region setting unit 120 . To this end, the measurement region information generation unit 130 may generate region ID information by tagging optical information measurement regions with different IDs. Here, the region ID information may be IDs represented by A1 to E6 as shown in FIG. 1 .

In addition, the measurement area information generation unit 130 may generate area location information that is a position between optical information measurement areas. In summary, the measurement area information generated by the measurement area information generation unit 130 is information for classifying and recognizing a plurality of optical information measurement areas into different areas. Area ID information and location information may be linked to corresponding information.

The mobile optical information measuring device 20 receives area movement information as user request information from a user terminal (not shown) connected using a wired or wireless communication network, and uses the received area movement information to measure optical information in a space ( 30) It may be formed to measure optical information of a specific optical information measuring area 32 by moving inside. Here, the light information may include at least one of illuminance, flicker, luminance, average value, standard deviation, and variance of the corresponding region, and at least one of color temperature, color coordinates, color rendering properties (Ra, R1 to R15, Rf, Rg, etc.) and DuV. may contain one.

For this purpose, the mobile optical information measurement device 20 may include a movement path generation unit 210, an optimal path selection unit 220, and an optical information measurement unit 230, as shown in FIG. 3 .

The movement route generator 210 is configured to generate at least one movement route when region movement information is acquired. The region movement information includes an optical information measurement region in which optical information measurement is required and a measurement sequence requested by the user. Here, the optical information measurement area may be represented by area ID information as described above.

An example of this is shown in FIG. 4 . Referring to FIG. 4A , in an embodiment, region movement information includes content requesting optical information measurement for optical information measurement regions having region ID information of A2, A4, B6, C3, and D5. In this case, the area movement information may request the measurement order in the order of A2, C3, D5, A4, and B6.

Meanwhile, in another embodiment of the present invention, the region movement information may include only region ID information of A2, A4, B6, C3, and D5, which are optical information measurement regions to be measured.

If the region movement information includes the optical information measurement order, the movement path generation unit 210 may generate a movement route connecting the corresponding region in the measurement order, as shown in FIG. 4A.

In addition, the movement path generation unit 210 may generate another movement path as shown in FIG. 4B if the region movement information does not include an optical information measurement sequence.

Although not shown in the drawing, the movement path generation unit 210 may set two paths from area C3 to area D5 in FIG. 4A, a path returning downward and a path returning upward.

Also, in FIG. 4B , since the movement path generation unit 210 generates movement paths in any order, it is possible to further generate a movement path that starts measurement at C3 and ends measurement at B6, which is not shown in the figure.

The optimal path generation unit 220 is configured to verify the movement path generated by the movement path generation unit 210 and select an optimal movement path. The optimum path generation unit 220 may check whether there is a problem with the movement path generated by the movement path generation unit 210 and generate an optimum path according to a predetermined optimal path determination condition. Here, the preset optimal path determination condition may be a condition of remaining battery power of the mobile optical information measuring device 20 or may be a condition of an optical information measurement execution area determined by an optical information measuring unit, which will be described later.

The optical information measuring unit 230 is formed to measure optical information of the optical information measuring region 32 to be measured. Here, the optical information measuring unit 230 may set an area adjacent to the optical information measuring area 32 included in the movement path as an optical information measuring area to measure optical information.

The mobile optical information measuring device 20 of the present invention is configured to move and measure optical information of a specific area 32 . At this time, as in the “X region” represented in FIGS. 4A and 4B , an area where loaded objects to which the mobile optical information measuring device 20 cannot approach exists within the optical information measuring space. These objects can cast shadows in certain directions, usually due to lighting radiating from the ceiling to the floor. Furthermore, the mobile optical information measuring device 20 also includes a system or device for measurement, and as a result, the mobile optical information measuring device 20 also has a height, and therefore, the light of the mobile optical information measuring device 20 Shadows are also created.

The mobile optical information measuring device 20 is a device that moves and stays for a while to measure, rather than being loaded and always located in the corresponding optical information measuring space. Therefore, in order to reach the objects and effects of the present invention, it is necessary to prevent or minimize measurement errors due to the shadow of the mobile optical information measuring device 20 .

Accordingly, the optical information measuring unit 230 of the present invention may be configured to newly designate an optical information measurement performing area. To this end, the optical information measuring unit 230 checks the ambient light source and measures the light information so that the mobile optical information measuring device 20 is not located between the checked ambient light source and the optical information measuring area where the current light information should be measured. to specify

More easily explained through the figure, it is assumed that the light source is positioned vertically above C3 in FIG. 4B. When light is emitted from the upper part of C3, there is some difference depending on the height of the "X area", but in the A4 area, a shadow may be generated in the 1 o'clock or 2 o'clock direction by the two "X areas" below. At this time, when the mobile optical information measuring device 20 of the present invention is located in A4 and measures light information, there is a possibility of measurement error due to the height and shadow of the mobile optical information measuring device 20 .

Therefore, in order to prevent such a measurement error, the optical information measuring unit 230 may determine to measure the optical information of A4 in the area A5 (see FIG. 1) between A4 and B6 and designate the area A5 as an area for performing optical information measurement. there is.

That is, in summary, the optical information measuring unit 230 of the present invention checks the location of the ambient light, and determines the location with the lowest probability of occurrence of measurement errors among the areas adjacent to the optical information measurement area to be measured according to the location of the ambient light. It is determined as an optical information measurement performing region, and may be configured to measure optical information of the optical information measuring region in the optical information measurement performing region.
