Hereinafter will be described in detail with reference to the accompanying drawings, the lighting control system according to the present invention according to this configuration.

3 to 7 are diagrams illustrating the use of a street lamp to which a light control system according to a first embodiment of the present invention is applied.

First, referring to FIG. 3, a street lamp 100 is disposed along a road, and a street lamp 100 and a lighting control unit 200-1 are disposed together at a crossroad. Conventionally, in the case of the street lamp 100 disposed on the road as described above, when lighting is required by night or the weather, it is always turned on.

On the contrary, in the case of the lighting control system according to the first embodiment of the present invention, the street lamp 100 maintains a state where all the lights are turned off, and the photographing unit 210 of the lighting control means 200-1 is disposed at the crossroad. Will shoot around the fork. At this time, the lighting control means 200-1 may be provided with a separate illumination for shooting of the photographing unit 210.

The object recognition unit 220 recognizes the presence or absence of the pedestrian P by comparing the front and rear frames of the image photographed by the photographing unit 210, which is made within the recognition effective area. The recognition effective area may be the maximum area that may be captured by the photographing unit 210, or may be an area where the object recognition unit 220 may identify an object in the captured image.

While the object recognition unit 220 compares the captured images, when the pedestrian P appears in the recognition effective area as shown in FIG. 4 and recognizes it, the manipulation unit 240 shows a street lamp closest to the pedestrian P that appeared. 100 will be turned on.

In addition, the path extractor 230 detects a moving area area of the pedestrian P by limiting the motion detection range of the pedestrian P in the captured image, and selects a reference point from the moving area area of the pedestrian P. By checking the moving path of the pedestrian (P) through the extraction direction of the pedestrian (P). Accordingly, the operation unit 240, as shown in Fig. 5 so that the street light 100, that is, the street light 100 disposed in the crossroads on the traveling direction of the pedestrian P, is turned on, and the pedestrian P faces the crossroads. When moving over a certain distance, the first lit street light 100 is turned off. At this time, the light-off of the street lamp 100 will be described in detail below.

Next, as shown in FIG. 6, the path extracting unit 230 checks which way the pedestrian P reaches the forked road and selects which path to proceed. When the pedestrian P selects the road to determine the traveling direction, Extract the direction of pedestrian P. Thus, when the pedestrian P moves over a predetermined distance, the operation unit 240 causes the street lamp 100 on the traveling direction to be turned on, and the street lamp 100 disposed at the crossroad is turned off. The lighting or turning off of the street lamp 100 will be described in detail below.

In this way, the lighting and turning off of the street lamp 100 disposed on the direction of the pedestrian P is performed within the recognition effective area of the lighting control means 200-1, and the pedestrian P continues to move forward. In this case, the recognition effective area of the lighting control means 200-1 is departed.

At this time, the pedestrian P leaves the recognition effective area of the lighting control means 200-1 and enters the recognition effective area of the other lighting control means 200-2 in the traveling direction of the pedestrian P. If so, the presence of the pedestrian P is recognized by the object recognition unit 220 of the other lighting control means 200-2, and the street lamp 100 in the traveling direction is turned on.

However, as shown in FIG. 7, after the pedestrian P leaves the recognition effective area of the lighting control means 200-1, the pedestrian P is further advanced a predetermined distance, so that the other lighting control means 200-in the traveling direction of the pedestrian P is moved. When entering into the recognition effective area of 2) the lighting control means 200-1 is another lighting control means 200-2 in the advancing direction of the neighboring lighting control means 200-2, that is, the pedestrian P. ) Will transmit the access information of the pedestrian (P).

The other lighting control means 200-2 receiving the access information of the pedestrian P in this way helps the safe movement by turning on the street lamp 100 closest to the pedestrian P in the traveling direction of the pedestrian P. I can give it.

8 to 11 are views illustrating a state in which a street light is on-off in the lighting control system according to the first embodiment of the present invention.

First, (a) of FIG. 8 is a state before the street light 100 in the traveling direction of the pedestrian P is turned on, and FIG. 8 (b) shows that the street light 100 is moved as the pedestrian P moves forward. 8C is a state in which the street light 100 is turned off as the pedestrian P moves forward. Here, the state in which the street light 100 is turned on and off in accordance with the advance of the pedestrian P is shown in the order of the upper part of (a) to (c) of FIG. 8, and in the lower part by the photographing unit 210 The state in which the street light 100 is turned on and off in accordance with the advance of the pedestrian P in the captured image is shown in order.

In the lighting control system according to the first embodiment of the present invention, the street lamp 100 is turned on by setting an effective lighting area of the street lamp 100 or setting an on reference point and an off reference point of the street lamp 100. Or it can be turned off. In this case, the on reference point of the street lamp 100 is referred to as a lighting reference point, and the off reference point is referred to as an unlit reference point.

First, when setting the effective lighting area of the street lamp 100, the distance from I to I 'displayed at the top of (a) to (c) of FIG. 8, that is, the bottom of (a) to (c) of FIG. In the image of the photographing unit 210 shown in the radius of a predetermined range from the street lamp 100 becomes the effective lighting area of the street lamp 100, such an effective lighting area is the minimum that the pedestrian (P) can secure the field of view It is a good idea to set the area where lighting is maintained. The effective lighting area depends on the distance from the street lamp 100 to the point in the vertical direction, that is, the height h of the street lamp 100. Also, the street lamp 100 includes sodium, halogen, incandescent and LED lights. It may vary depending on the type of streetlight 100, such as made of any of the lamps.

Accordingly, the effective lighting area of the street lamp 100 may be actually measured, and then the measured information may be input to the lighting control means 200, and the type of the street lamp 100 and the height h of the street lamp 100 may be used. When input to the lighting control means 200, it may be calculated to set the effective lighting area of the corresponding street light 100, or may be estimated to set the effective lighting area of the general street light 100 to the effective lighting area of the corresponding street light (100).

On the other hand, when setting the lighting and extinguishing reference point of the street lamp 100, I shown at the upper end of Figs. 8A to 8C is the lighting reference point, and I 'is the extinguishing reference point. The lighting reference point (I) and the extinguishing reference point (I ') is preferably set based on the effective lighting area of the above-described street light 100, and thus the street light 100 is turned on as the pedestrian P moves forward. The light off can be made at the same point when the effective lighting area is set and the case where the lighting and the light off reference points I and I 'are set.

Therefore, in FIGS. 8A to 8C, when the pedestrian P reaches the effective lighting area or the lighting reference point I of the street light 100 disposed in the traveling direction, the street light 100 is turned on. When the lamp deviates from the effective lighting area of the street lamp 100 or reaches the extinguishing reference point I ′, the street lamp 100 is turned off.

In FIG. 9A, two street lamps 100-1 and 100-2 are disposed, and effective lighting regions of the street lamps 100-1 and 100-2 overlap each other, and the direction in which the pedestrian P travels. According to the pedestrian (P) reaches the effective lighting area or the lighting reference point (I) of the street light (100-1), the first street light (100-1) is turned on, and continues to move forward of the neighboring second street light (100-2) When the effective lighting area or the lighting reference point II is reached, the neighboring second street lights 100-2 are also turned on so that both street lights 100-1 and 100-2 are turned on.

As shown in FIG. 9B, when the pedestrian P continues to advance and leaves the effective lighting area of the first street light 100-1, or reaches the extinguishing reference point I ′, the first street light 100-1 is moved. It will be turned off. Similarly, the neighboring second street light 100-2 is also turned off when the pedestrian P leaves the effective lighting area or reaches the extinction reference point II '.

On the other hand, Figure 10 (a) shows a state in which the effective lighting areas of the street lights (100-1, 100-2) abut each other, in this case pedestrian (P) is the effective lighting area of the first street light (100-1) or By reaching the lighting reference point I, the first street light 100-1 is turned on and continues to advance, and then leaves the effective lighting area or the extinguishing reference point I 'of the first street light 100-1 as shown in FIG. At the same time, the effective lighting area or the lighting reference point II of the neighboring second street light 100-2 is reached and the first street light 100-1 is turned off, and the neighboring second street light 100-2 is turned on.

Here, when the pedestrian P reaches the effective lighting area or the lighting reference point (I, II) of the street lamp 100-1 or the neighboring street lamp 100-2, the corresponding street lamps 100-1, 100-2 are Although it is described as being lit, when the pedestrian (P) reaches the effective lighting area or the lighting reference point (Ⅰ) of the street lamp (100-1) according to various conditions such as rainy weather or the region is a hot spot. Not only the street lamp 100-1 but also one or two or more of the neighboring street lamps 100-2 in the traveling direction of the pedestrian P may be turned on at the same time.

In FIG. 11, more street lights are disposed than the street lamps shown in FIG. 9 or 10.

In the case of FIG. 11, the effective lighting area of the street lights 100-1, 100-2, 100-3, and 100-4 is set and used in FIGS. 9A and 10B or FIG. 10A. Like in the case of) and (b), the street lamps 100-1, 100-2, 100-3, 100-4 are turned on or off, but they are applied differently when the lighting and extinguishing reference points are used instead of the effective lighting area. One example is shown.

For example, in FIG. 9, each of the street lights 100-1 and 100-2 has a lighting reference point I and II and an extinguishing reference point I 'and II', and the pedestrian P has a lighting reference point I and. When the lamp reaches (II), the corresponding street lights 100-1 and 100-2 are turned on. When the lamp lights reach the extinguishing reference points I 'and II', the corresponding street lights 100-1 and 100-2 are turned off.

That is, in FIG. 9, when the pedestrian P reaches the extinguishing reference point I ′ of the first street light 100-1, the first street light 100-1 is turned off. However, in FIG. 11A, the pedestrian ( When P) reaches the extinguishing reference point I ′ of the first street lamp 100-1, the first street lamp 100-1 is not turned off, but a lighting reference point for turning on the third street lamp 100-3 in the traveling direction ( Ⅲ) and not shown, but used as an extinction reference point at which the street light before the first street light 100-1 in the direction of travel of the pedestrian P is turned off.

Next, when the pedestrian P continues to advance so that the pedestrian P reaches the extinguishing reference point II ′ of the second street light 100-2, the second street light 100-2 is turned off in FIG. 9, but FIG. 11. In (b), the fourth street lamp 100-4 is turned on in the traveling direction of the pedestrian P and at the same time, the first street lamp 100-1 is turned off to be the lighting reference point IV of the fourth street lamp 100-4 and the first street lamp. It becomes an extinction reference point (I ') of (100-1).

That is, the lighting reference points (Ⅰ, II, Ⅲ, Ⅳ) and the extinguishing reference points (I ', II', Ⅲ ', Ⅳ') are pedestrians depending on various conditions such as rainy weather or the region is a hot spot. Change the lighting or extinguishing condition of the street lights (100-1, 100-2, 100-3, 100-4) in the traveling direction of P), and the front and rear of the pedestrian (P) until the pedestrian (P) advances a certain distance or more. One or more street lamps disposed in the can be configured to be turned on or off. In addition, when the pedestrian P reaches the lighting reference point I of the first street lamp 100-1 according to the setting in FIG. 11, the first street lamp 100-1 and the second street lamp 100-2 are simultaneously turned on. According to the distance change between the pedestrian P and the street lights 100-1, 100-2, 100-3, 100-4, the street lights 100-1, 100-2, 100-3, 100-4 The illuminance of may be configured to change. For example, as the pedestrian reaching the lighting reference point I of the first street lamp 100-1 moves toward the second street lamp 100-2 in FIG. 11, the second street lamp 100-2 may be brighter. It is.

Meanwhile, in the drawing, the lighting reference points I, II, III, and IV and the extinguishing reference points I ', II', III ', and IV' are shown in the street lights 100-1, 100-2, 100-3, and 100-. Located at the end of the effective lighting area of 4), the pedestrian P reaches the effective lighting area and the lighting reference points I, II, III, and IV are the same, and the pedestrian P defines the effective lighting area. Departure and reaching the extinction reference point (I ', II', III ', IV') is shown to be the same, but lights up depending on the area in which the lighting control system according to the first embodiment of the present invention is installed or the situation in which it is used. The reference point (I, II, III, IV) or the extinction reference point (I ', II', III ', IV') can be variously applied, such as being set near the center of the effective lighting area.

FIG. 12 illustrates a state in which the street light 100 is turned off when the pedestrian P disappears, as opposed to recognizing the appearance of the pedestrian P in FIG. 4 and turning on the street light 100.
