Problems solved by technology

[0003] The supplementary light method provided in the related art completely depends on the supplementary light, which is not flexible enough
Although it is possible to adjust the overall brightness of the captured image, it cannot ensure that the brightness of the region of interest meets the recognition requirements
Not only that, the supplementary light method provided by related technologies is not universal, and it does not perform well when applied to some surveillance cameras
In addition, there will be a problem of repeated flashes during the fill-in light process.

[0040] Please refer to figure 2 , figure 2 The image supplementary light adjustment method provided by the embodiment of the present invention is shown. The above-mentioned image supplementary light adjustment method may be applied to the above-mentioned electronic device 100 . Such as figure 2 As shown, the above image supplementary light adjustment method includes the following steps:

[0041] Step S101, acquiring the average brightness value of the region of interest in the collected image data.

[0042] The above-mentioned electronic device 100 continuously collects images of the monitored area, and puts the image data into a queue to be processed when the image data of the region of interest is collected. The queue to be processed is used to store image data with regions of interest. Optionally, the acquired image data with the region of interest is sequentially buffered in the queue to be processed according to the order of acquisition time. After the queue to be ...

example 1

[0087] S1. A human face image area appears in the image data collected by the electronic device 100, and the image data is stored in a queue to be processed.

[0088] S2, according to the preset time period, sequentially calculate the average brightness value of the faces appearing in each piece of image data in the queue to be processed.

[0089] S3. After superimposing the average brightness value of the faces appearing in each image data in the queue to be processed, divide by the number of images in the queue to be processed to obtain the corresponding average brightness value.

[0090] S4, judging whether the average brightness value belongs to a preset stable brightness interval. If not, enter the intelligent adjustment mode, that is, the process enters step S5. If yes, enter the brightness stabilization mode, that is, the process enters step S11.

[0091] S5. If the average brightness value is greater than the upper limit of the preset stable brightness interval, calc...

[0099] D1, a human face image area appears in the image data collected by the electronic device 100, and the image data is stored in a queue to be processed.

[0100] D2, according to the preset time period, sequentially calculate the average brightness value of the faces appearing in each piece of image data in the queue to be processed.

[0101] D3, after superimposing the average brightness value of the faces appearing in each image data in the queue to be processed, dividing by the number of images in the queue to be processed, to obtain the corresponding average brightness value.

[0102] D4, judging whether the average brightness value belongs to the current stable brightness interval. Wherein, the current stable brightness interval may be a preset stable brightness interval, or may be an extended brightness interval. The extended brightness interval is an extended brightness interval based on a preset stable brightness interval.

Abstract

Embodiments of the present invention provide an image supplementary light adjustment method, device and electronic equipment, which relate to the technical field of monitoring. Wherein, the image supplementary light adjustment method includes: obtaining the average brightness value of the region of interest in the collected image data; according to the linear index of the supplementary light of the electronic device, judging whether the brightness average value satisfies a preset stable condition ; If the average brightness value does not satisfy the stability condition, adjust the working state of the supplementary light or the exposure of the electronic device according to the average brightness value. In this way, not only can it adapt to various electronic devices with linearity, realize intelligent and flexible fill light, but also adopt two ways of adjusting flash and adjusting exposure to make full use of the advantages of both to avoid the problem of repeated flashing of fill light .

Description

technical field [0001] The invention relates to the technical field of monitoring, in particular to an image supplementary light adjustment method, device and electronic equipment. Background technique [0002] With the development of artificial intelligence technology, image recognition technology has been widely used in various industries. Especially in the security industry, surveillance cameras capable of image recognition of captured images are also widely used in urban construction. The key to ensure accurate image detection and high recognition rate is image quality. The lighting environment when collecting images has a great impact on image quality. For example, when the lighting environment is poor, the brightness of the collected image data is low, making it difficult to perform image processing. However, surveillance cameras are usually installed in an outdoor environment where the lighting environment is uncontrollable. Therefore, it is very important to suppl...
