[0022] S1: Get a map of the lighting area;

[0023] S2: Acquire monitoring images including each position of the lighting area, and then determine the lighting brightness of each position of the lighting area. For each position of the lighting area, perform corresponding lighting brightness on the corresponding position on the map according to the lighting brightness of the position, and form a marked map;

[0024] S3: comparing the marked map with a preset standard brightness distribution map of the lighting area to determine insufficiently lit areas, adequately lit areas, and excessively lit areas in the real-time brightness distribution map, thereby forming a real-time brightness distribution map;

[0025] S4: adjusting the lighting direction and / or light brightness of the street lamp, executing steps S2 to S3 to update the real-time brightness distribution map, and repeating this step until the insufficiently lit area and the excessively lit area in the real-time brightness distribution map are converted into the adequately lit area;

[0026] S5: After the adjustment is completed, execute steps S2 to S3 to determine whether the real-time brightness distribution map has added insufficient lighting areas and / or excessive lighting areas. If the real-time brightness distribution map has added insufficient lighting areas and / or excessive lighting areas, execute step S4 and repeat this step until the street light is turned off.

[0027] In this embodiment, if Figure 2 As shown, the lighting area is a ground area that needs to be illuminated as preset by the staff when carrying out street planning. A number of street lamps are installed in the lighting area, and the street lamps have adjustable light direction (adjustable by controlling the lamp head of the street lamp to rotate) and brightness; a number of cameras are arranged in the lighting area, and the cameras can be set on the street lamps or at other positions, so that the sum of the ground range in the field of view image of each camera covers the entire lighting area; the method is executed in a terminal device, and the terminal device can be an independent physical server or terminal, or a server cluster composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud servers, cloud databases, cloud storage and CDN; the terminal device communicates with each street lamp and camera, and can obtain corresponding monitoring images from the camera, and adjust each camera accordingly.

[0028] In this embodiment, each position in the lighting area refers to an area of ​​a specific size, such as a square area with a length and width of 10 cm respectively, which is a component unit of the lighting area. When demarcating the lighting area, the staff divides the lighting area into several positions that constitute the lighting area; the corresponding positions are also divided on the map of the lighting area to form a grid map; at the same time, the staff first formulates a standard brightness distribution map according to the actual use needs of the lighting area (representing the same area as the map of the lighting area, and divided into grids with the same corresponding positions), and the standard brightness distribution map is divided into multiple sub-areas according to the use needs (each sub-area consists of several positions), and each sub-area is for a purpose, such as a road area and an entertainment area; a lighting brightness range is preset for different sub-areas to meet the lighting brightness requirements of the area; the annotated map is a map formed by annotating the real-time lighting brightness of each position on the map, and it can be compared with the standard brightness distribution map to determine the insufficiently lit area, the sufficiently lit area and the over-lit area, and these three areas are all composed of several positions.

[0029] In the present application, real-time monitoring of the lighting brightness at each location in the entire lighting area is achieved, and clear boundary adjustments are defined, based on which the lighting direction and brightness of each street lamp are coordinated and adjusted, so that both insufficiently lit areas and over-lit areas can be converted into sufficiently lit areas, thereby achieving uniformity of illumination, ensuring lighting effects and effective use of light; and being able to monitor in real time the changes in ambient light (such as lights from businesses, lights from residents, etc.) that affect the lighting brightness at each location, and making corresponding adjustments to the street lamps based on these changes in real time, thereby ensuring continuous uniform lighting effects; in addition, at a set time, such as at 5 a.m., all street lamps are turned off, and this method is repeatedly executed at night until the street lamps are turned off, thereby achieving an adjustment effect within the entire working time range of the street lamps.

[0030] As a preferred embodiment, a plurality of cameras are arranged in the lighting area, and the sum of the ground ranges in the field of view images of the various cameras covers the entire lighting area; the lighting brightness at each position in the lighting area is represented by the grayscale value of the position in the field of view image of the camera;

[0031] Acquire monitoring images including each position of the lighting area, and then determine the lighting brightness of each position of the lighting area. For each position of the lighting area, perform corresponding lighting brightness analysis on the corresponding position on the map according to the lighting brightness of the position, including:

[0032] S21: Get a field of view image of a camera;

[0033] S22: Identify the ground range in the field of view image, and then determine the map range corresponding to the ground range on the map;

[0034] S23: grayscale processing of the visual field image;

[0035] S24: for each position in the ground range, identifying the grayscale value of the position point, and marking the grayscale value at the corresponding position in the map range;

[0036] S25: Get the field of view image of another camera, and execute steps S21 to S25 until the corresponding grayscale value is marked at each position on the map.

[0037] Identifying the ground range in the field of view image and then determining the map range corresponding to the ground range on the map includes:

[0038] S221: identifying a ground reference object in the ground range of the field of view image, taking the position of the ground reference object as a first position, and determining a second position corresponding to the first position on the map;

[0039] S222: Select another position within the ground range as a comparison position;

[0040] S223: Identify the relative position between the comparison position and the first position;

[0041] S224: determining a target position corresponding to the comparison position on the map according to the identified relative orientation and the second position;

[0042] S225: Repeat steps S221 to S224 until a target position corresponding to each other position in the field of view image is obtained, and each target position and the second position constitute a map range corresponding to the ground range on the map.

[0043] In this embodiment, in a night environment, the grayscale value (0 to 255) of a position can represent the lighting brightness of the position, and the higher the grayscale value, the higher the lighting brightness; for each position, the average grayscale value of all pixels in the position can be taken as the grayscale value of the position; in this embodiment, the ground range in the field of view image of each camera is a local range of the lighting area, and the map range corresponding to the ground range in each lighting area is spliced ​​together to obtain a map of the entire lighting area; the ground reference object is an object recorded on the map, such as a street lamp or a telephone pole, and the position corresponding to the bottom center of the ground reference object is taken as the first position, and then the second position can be locked on the map; the relative orientation of the comparison position and the first position, that is, the direction and distance of the comparison position compared to the first position, can be identified according to the existing image depth of field recognition algorithm (such as the OpenCV algorithm); this embodiment realizes the one-to-one correspondence between the actual area in the monitoring video and the position on the map, and marks the lighting brightness of each position, so as to facilitate further division of the map according to the lighting brightness.

[0044] As a preferred embodiment, the standard brightness distribution map is divided into several sub-areas, and each sub-area is pre-marked with a standard grayscale value range; the grayscale value range of each position in the standard brightness distribution map is the standard grayscale value range of the sub-area where the position is located; the marked map is compared with the preset standard brightness distribution map of the lighting area to determine the insufficient lighting area, the sufficient lighting area and the excessive lighting area in the real-time brightness distribution map, and the real-time brightness distribution map is formed, including:

[0045] Overlay the standard brightness distribution map with the annotated map;

[0046] For each position of the annotated map, determine whether the grayscale value of the position falls within the standard grayscale value range of the position of the standard brightness distribution map corresponding to the position, and if so, render the position point as the first color on the annotated map;

[0047] If not, determine whether the grayscale value at the position is greater than the maximum value of the corresponding standard grayscale value range or less than the minimum value of the corresponding standard grayscale value range;

[0048] If the grayscale value of the location is greater than the maximum value of the corresponding standard grayscale value range, the location is rendered as a second color on the annotated map;

[0049] If the grayscale value of the location is less than the minimum value of the corresponding standard grayscale value range, the location is rendered as a third color on the annotated map;

[0050] On the annotated map, the area composed of positions rendered in the first color is regarded as a well-lit area, the area composed of positions rendered in the second color is regarded as an over-lit area, and the area composed of positions rendered in the third color is regarded as an under-lit area, thereby forming a real-time brightness distribution map.

[0051] A number of street lamps are arranged in the lighting area; the lighting direction and / or light brightness of the street lamps are adjusted, that is, the street lamps are coordinated and the lighting direction and / or light brightness of each street lamp is adjusted when the street lamp is adjusted.

[0052] In this embodiment, if Figure 3 As shown, the standard grayscale value ranges of positions in different sub-areas are different. This is an implementation method determined by the specific settings of the staff and is not limited here. The standard brightness distribution map is superimposed on the annotated map, that is, the two maps are completely overlapped, so that each group of corresponding positions overlaps for easy comparison. The first color, the second color and the third color can be green, red, blue, or other color combinations, respectively, which are not limited here. For the second color and the third color, the depth of the color can be adjusted according to the specific value of the position. For example, the closer to the standard grayscale value range, the lighter the color condition, and vice versa, the darker the color; when adjusting, the terminal device coordinates to control each street lamp to perform ergodic adjustment, which takes the set boundary adjustment as the goal (converting the insufficiently illuminated area and the over-illuminated area into the fully illuminated area), and converts various lighting states (lighting direction and brightness) of each street lamp. The adjustment method includes but is not limited to adjusting the brightness, adjusting the direction, illuminating a certain area together with other street lamps, separating the street lamp lights that jointly illuminate a certain area, etc., and finally stops adjusting after achieving the adjustment target; the terminal device can refer to the changes in the real-time brightness distribution map in real time when performing each step of adjustment, which has higher adjustment efficiency.

[0053] As a preferred embodiment, during the process of executing step S4, the following steps are further included:

[0054] Storing each updated real-time brightness distribution map and the lighting direction and light brightness of each street lamp corresponding to the real-time brightness distribution map;

[0055] If the insufficiently lit area and the over-lit area are still not completely converted into the well-lit area after adjusting the preset duration of the street lamp, the proportion of the insufficiently lit area in each stored real-time brightness distribution map is calculated;

[0056] Filter out the real-time brightness distribution map with the smallest proportion of insufficiently lit areas;

[0057] The lighting direction and light brightness of each street lamp are adjusted to the lighting direction and light brightness of the street lamp corresponding to the screened real-time brightness distribution map.

[0058] The proportion of insufficient lighting area is calculated by the following formula:

[0059]

[0060] Among them, P is the proportion of insufficient lighting area, S 3 is the area of ​​the insufficiently illuminated area, S t is the area of ​​the real-time brightness distribution map.

[0061] In this embodiment, the preset duration can be 2 minutes, 5 minutes or other durations, which are not limited here; sometimes the adjustment target cannot be achieved. In order to avoid endless adjustment, the maximum adjustment time is limited by setting a preset duration; furthermore, during the adjustment process, the real-time brightness distribution diagram after each step of adjustment and the corresponding lighting status of each street lamp can be recorded to select the currently known best lighting state and adjust each street lamp to this lighting state.

[0062] As a preferred embodiment, it is determined whether the real-time brightness distribution map has newly added under-lit areas and / or over-lit areas, that is, the latest real-time brightness distribution map is compared with the real-time brightness distribution map when the last adjustment was completed, so as to determine whether the latest real-time brightness distribution map has newly added under-lit areas and / or over-lit areas compared with the real-time brightness distribution map when the last adjustment was completed.

[0063] In this embodiment, the ambient light may change, such as when a business closes and turns off the lights, opens the door and turns on the lights, or when residents on the floor turn on the lights, etc. This embodiment realizes real-time adjustment of each street lamp according to the changes in the ambient light to ensure the lighting effect of the lighting area under various ambient light conditions; in this embodiment, when a new area that needs to be adjusted is added, the terminal device can first determine whether it is a temporary addition or a continuous addition. The judgment standard can be whether the maintenance time of the newly added area that needs to be adjusted exceeds a set time (such as 30 seconds), thereby reducing unnecessary adjustments.
