From such image information, the object recognition unit 122 may recognize a moving object, determine whether the recognized object is a person or a vehicle, and determine which direction the object moves.

The information on the identified object is classified according to the type and direction of the object, and transmitted to the server 3000 to derive lighting control information capable of providing optimal lighting according to the movement of the object. can do.

For example, information of an object shown in FIG. 9 may be displayed as (vehicle, L -> C), and information of an object shown in FIG. 10 may be displayed as (person, C -> L). have.

11 is a diagram schematically showing a camera system and mapping information for the camera system according to an embodiment of the present invention.

In (a) of FIG. 11, only the camera system #1 (1000.1) of the camera system 1000 of the parking lot shown in FIG. 2 is shown. The camera module #1 (100.1) of the camera system #1 (1000.1) of FIG. 11 is located at an intersection of a moving section of a vehicle in a parking lot, and controls six lights installed near the intersection.

Referring to (a) of FIG. 11, the camera system #1 (1000.1) according to an embodiment of the present invention identifies four directions of the camera module #1 (100.1) with symbols of L, R, U, and D. The center where module #1 (100.1) is located is identified by the symbol of C. In addition, according to the distance from the camera module #1 (100.1), it is divided into 1, 2, 3, 4 zones in a distant order.

Among the lights of the camera system #1 (1000.1), lights 1-1 and 1-2 are installed in the L direction, lights 1-3 are in the U direction, lights 1-4 are in the D direction, and the lights 1-5 and lights 1-6 are installed in the R direction.

11B shows a part of mapping information for the camera system #1 (1000.1).

Object information is stored in column 1 of the mapping information, and brightness information for each light is stored in columns 2 to 7.

Looking at the object information among the mapping information shown in Fig. 11(b), PLC1 in row 1 indicates that the recognized object is a person (P), is moving from the L direction to the C direction, and is located at a distance of the 1 area. Show.

VLC3 in line 6 of the object information indicates that the recognized object is a vehicle (V), is moving from the L direction to the C direction, and is located at a distance of the 3rd area.

Looking at the mapping information shown in FIG. 11, the situation of PLC1, that is, when a person moves from zone 1 in the L direction to the direction C, means that the person moves from the vicinity of the illumination 1-1 to the illumination 1-2 direction. . At this time, according to the mapping information, in the context of PLC1, lighting 1-1 has a brightness of 60%, lighting 1-2 has a brightness of 40%, lighting 1-3, lighting 1-4, lighting 1-5, and lighting 1 -6 corresponds to 30% brightness. In other words, it is possible to save energy by blocking lights that are not necessary for people's movement while providing lighting necessary for people to move by keeping the lights close to the place where the person is located bright and the lights far away from the place where the person is located. .

In the situation of PLC2, a person moves between light 1-1 and light 1-2 in the direction of light 1-2. At this time, according to the mapping information, the light 1-1 and the light 1-2 have a brightness of 60%, the light 1-3, the light 1-4, and the light 1-5 have 40% brightness, and the light 1-6 is 30%. Corresponds to the brightness of. Compared to the PLC1, the brightness of the lights 1-2 is brightened from 40% to 60%, and the brightness of the lights 1-3, lights 1-4 and 1-5 is brightened from 30% to 40%, which is recognized Since the person is closer to the camera module #1 (100.1), the brightness of the illumination is brightened as a result of the closer illumination 1-3 to illumination 1-6. As described above, according to the mapping information, lighting required for the object can be efficiently provided by controlling lighting according to the position of the recognized object.

In the situation of PLC3, a person moves in the direction of the camera system #1 (1000.1) in the vicinity of the illumination 1-2. At this time, according to the mapping information, light 1-1 has a brightness of 40%, light 1-2 has a brightness of 60%, light 1-3, a light 1-4 and a light 1-5 have a brightness of 50%, and a light 1 -6 corresponds to 40% brightness. Compared to the PLC2, the brightness of the lights 1-3 to the lights 1-6 was brightened by 10%, and the illumination 1-1 was darkened from 60% to 40%. In this case, the illumination 1-1 has a similar distance to a recognized person compared to the illuminations 1-3 to 1-5, but the brightness is darker. This is because the recognized person moves in the direction of the camera module #1 (100.1) in the illumination 1-2, so it is the opposite direction of the movement of the recognized person, so there is no need for bright lighting, and energy can be saved by dimming the brightness. There will be. As described above, in an exemplary embodiment of the present invention, by adjusting the brightness of lighting in consideration of the direction of movement of the recognized object, it is possible to achieve an effect of saving energy while providing necessary lighting to the object.

In the situation of VLC1, VLC2 and VLC3, that is, when the vehicle is recognized, the brightness of the lighting is controlled similarly to the situation of PLC1, PLC2 and PLC3.

However, in the case of a vehicle, a moving speed is faster than that of a person, and since a person in the vehicle sees the outside of the vehicle through the glass of the vehicle, a brighter light is required even further away. Accordingly, the situation of VLC1, VLC2, and VLC3 when the vehicle is recognized can be controlled to have a brighter brightness of each light than that of PLC1, PLC2 and PLC3. According to the mapping information, in the situations of VLC1, VLC2 and VLC3, the brightest illumination is controlled to 100% brightness, and is generally controlled to be about 30 to 40% brighter than that of PLC1, PLC2 and PLC3.

12 is a diagram schematically illustrating a camera system and mapping information for the camera system according to an embodiment of the present invention.

As shown in FIG. 11, the brightness of lighting may be controlled according to the situation of the object recognized through the mapping information. In this case, by adjusting the data of the mapping information, it is possible to control the lighting suitable for the situation.

12(a) shows the camera system #1 (1000.1) as shown in FIG. 11(a). At this time, if the parking lot where the camera system #1 (1000.1) is installed has an vacant seat 30 where a vehicle can be parked, a guide will be provided so that the vehicle entering the parking lot can easily find and go to the vacant seat 30. I can. As shown in (a) of FIG. 12, the empty seat 30 is located near the illumination 1-4.

In FIG. 12B, mapping information of lighting that can induce the vehicle to easily find the empty seat 30 is shown.

The mapping information shown in (b) of FIG. 12 is the same as the mapping information shown in (b) of FIG. 11 in the case of PLC1, PLC2, and PLC3 where humans are recognized.

On the other hand, in the case of VLC1, VLC2, and VLC3 in which the vehicle is recognized, there is a difference from the mapping information shown in FIG. 11B.

Specifically, in the case of VLC1, the brightness of illumination 1-3 and illumination 1-5 was 60% in FIG. 11(b), but 40% in FIG. 12(b). In addition, in the case of VLC2, the brightness of illumination 1-3 and illumination 1-5 was 70% in FIG. 11(b), but 60% in FIG. 12(b), and in the case of VLC3 illumination 1-3 and illumination 1-5 The brightness of was 80% in FIG. 11(b), but 60% in FIG. 12(b). As described above, in the embodiment of FIG. 12 (b), the brightness of the lights 1-3 and 1-5 is controlled to be dark by about 10 to 20%.

In this way, at the intersection where the camera module #1 (100.1) is located, the lights 1-3 and the lights 1-5 are controlled to be relatively dark compared to the lights 1-4, so that the driver of the vehicle can easily find an empty seat in the direction of the lights 1-4 ( It can be seen that 30) is located, and it is possible to arrive at the vacant seat 30 by moving along the light controlled brightly.

In a similar way, the vehicle may be guided through lighting, such as to the exit of the parking lot instead of the empty seat 30. To this end, by tracking a vehicle in a parking lot through the camera unit 110 of the camera module 100 or the like, it is possible to determine whether the vehicle is a vehicle entering for parking or a vehicle leaving after parking.

As described above, according to an exemplary embodiment of the present invention, a vehicle recognized by controlling the brightness of lighting may be guided to a specific place to guide the vehicle.

According to an embodiment of the present invention, by controlling the lighting of a parking lot through a server, it is possible to achieve an effect of simultaneously controlling a plurality of lights.

According to an exemplary embodiment of the present invention, by controlling lighting using object recognition, it is possible to achieve the effect of operating and managing a control system quickly and accurately.
