In this step, image acquisition device is installed to the lamp holder portion of high-pole lamp, acquires the experimental image in a plurality of park squares through this image acquisition device, and this image acquisition device acquires the experimental image in a plurality of park squares through the angle of overlooking. The position of the image acquisition device is unchanged, so the angle of the acquired image is also fixed. The experimental images are images of park squares at different times, for example, images of squares with more than eight to ten people at night and images of squares with less than twelve to two people at noon, and the moving areas of people in the images can be obtained by comparing the images of squares at different times.

S103, analyzing the plurality of experimental images and finding out the human activity area in the experimental images.

By comparing the images of squares at different times, for example, the images of squares with eight to ten people at night and the images of squares with twelve to two people at noon, the difference between the two images can be found out, so that the moving area of people in the images, namely the moving area of people on the park square, can be obtained.

S105, determining a first number of elliptical contours in the human activity area in the first state.

The first state includes, for example, a time of eight to ten nights, that is, a time point of many people. Because the image acquisition device obtains the experimental image of a plurality of park squares through the angle of overlooking, that is the camera is with the angle of overlooking collection square people's image, in the image of gathering, people's head is the ellipse, through obtaining the first quantity of oval outline in the people's active area, just can obtain people's quantity.

The image acquisition device installed through the lamp holder part of high-pole lamp acquires the first image of park square. The second number of elliptical contours of the region of human activity in the first image, i.e. the number of people on the square at the moment the first image was acquired, is then analyzed.

Controlling the brightness of the outdoor LED lamp according to the comparison result of the first number and the second number, for example, includes: when the second quantity is larger than or equal to the first quantity, the brightness of the outdoor LED lamp is kept unchanged; when the second number is smaller than the first number, namely, the number of people on the square at the present moment is less than that of people at ordinary times, determining the difference value between the second number and the first number; when the difference value between the second quantity and the first quantity is in a first gradient, the brightness of the outdoor LED lamp is reduced by 10%; when the difference value between the second quantity and the first quantity is in a second gradient, the brightness of the outdoor LED lamp is reduced by 20%; and so on; the ranges of the first gradient and the second gradient may be determined experimentally or empirically.

When the brightness of the outdoor LED lamp is reduced to the threshold value, the brightness of the outdoor LED lamp is not reduced any more, so that the brightness of the outdoor LED lamp is reduced to a certain degree and is not reduced any more, and a basic lighting function is guaranteed.

In some embodiments, the control method of the outdoor LED lamp further includes: acquiring a first sound decibel of an outdoor LED lamp within a first distance; comparing the first sound decibel with a preset sound decibel, wherein the preset sound decibel is the decibel in the first state; and controlling the brightness of the outdoor LED lamp according to the comparison result of the first sound decibel and the preset sound decibel and the comparison result of the second quantity and the first quantity. The first state includes, for example, time points from eight to ten nights, that is, time points at which there are more people, and if the current sound decibels are lower than the sound decibels in the first state, it indicates that there are fewer people than in the first state. The preset sound decibels can be obtained in advance, the sound decibels in the first distance of the outdoor LED lamp are collected from eight to ten points at night, the sound decibels can be collected for multiple times, and then the average value is calculated.
