The LED lamp ring is widely used on intelligent hardware, and along with the development of the LED lamp ring, the brightness uniformity of the lamp ring formed by a plurality of LEDs is more and more strongly required by users. As the lamp ring is used as a main user interaction means of the intelligent product, the user is very sensitive to the effect of the light, so that the actual light effect on the product can hardly meet the requirement of the user. And one colored LED lamp just contains the three sub-lamps of RGB, because the luminance of the RGB three-color lamp of every lamp is inconsistent, sees exactly that the RGB parameter that spreads into is the whole is the same, and the actual light effect is some lamps on the green side, some lamps on the blue side, some lamps on the red side, has increased the debugging degree of difficulty more, has also influenced the lamp effect. Therefore, how to accurately control the brightness of the lamp light is a problem to be solved at present.
In order to solve the problems in the background art and the above-mentioned problems, an embodiment of the present application provides a method for controlling light brightness based on an LED, please refer to fig. 1, and fig. 1 is a schematic flow chart of the method for controlling light brightness according to the embodiment of the present application. The light brightness control method is applied to electronic equipment, the electronic equipment is connected with an LED light-emitting system, and the LED light-emitting system comprises at least one LED lamp. The light brightness control method comprises the following steps:
s200, acquiring a plurality of luminous images of the LED luminous system under a preset condition.
S201, acquiring brightness calibration information of at least one LED lamp according to the plurality of luminous images.
The brightness calibration information is used for indicating that each LED lamp is adjusted to a specified brightness, and the brightness calibration information comprises an identification of each LED lamp.
S202, adjusting the LED light-emitting system to the specified brightness according to the brightness calibration information.
It can be understood that the brightness calibration information of the LED light-emitting system is obtained by obtaining the image of the LED light-emitting system under the preset condition, and the brightness of the LED light-emitting system in use is adjusted through the brightness calibration information, so that the using effect of the LED light-emitting system does not depend on the uniformity of the LED lamp, the requirement on the consistency of the LED lamp is reduced, and the light effect is improved.
It is anticipated that the process of collecting the plurality of light-emitting images can be performed in a darkroom, so as to obtain the RGB brightness of the LED tri-color lamp in real time, analyze the brightness difference of the light-emitting images, digitize the brightness difference by the number of photosensitive elements of the camera or the camera, and complete the collection of the brightness calibration information, so as to serve as a data support for the subsequent control of the LED lighting system.
In an alternative embodiment, in order to obtain the brightness calibration information, a possible implementation manner is provided on the basis of fig. 1, please refer to fig. 2, and fig. 2 is a schematic flow chart of another method for controlling the brightness of the light provided in this embodiment of the present application. The above S201 may include:
s201a, preprocessing the multiple luminous images, and acquiring the luminous center of at least one LED lamp.
The above-mentioned preprocessing may include: binarization, edge detection, image filling and circle center connected domain calculation. As can be understood, the binarization processing is performed on the light-emitting image to obtain the edge information of the LED lamp in the light-emitting image, and the pattern filling processing (for example, filling the edge information into a circle) is performed on the edge information of the LED lamp; and calculating a connected domain of the region filled with the pattern, wherein the connected domain is the filled pattern, and further acquiring the light emitting center of the LED lamp. It is anticipated that the above-mentioned preprocessing is only one of many possible implementations, and those skilled in the art may also adopt other preprocessing methods with higher or lower precision for obtaining the luminescence center.
S201b, acquiring the average gray scale of each LED lamp in the light-emitting area.
The light emitting area is an area with a light emitting center as a circle center and a radius of a preset pixel. For example, the preset pixel may be 100 pixels or 200 pixels, and the specific value thereof may be determined according to the brightness adjustment requirement of the LED lighting system; it should be understood that although the embodiments of the present application exemplify the light emitting area with a radius, the embodiments may also be other pattern areas, such as a hexagon, a triangle, a square, etc.
S201c, establishing an association relation between the identity of each LED lamp and the corresponding average gray scale, and storing the association relation as the brightness parameter information of the LED light-emitting system.
S201d, acquiring brightness calibration information according to the brightness parameter information.
It can be understood that the identification marks are used for distinguishing the brightness calibration information for each LED lamp, and the brightness of the LED light-emitting system can be accurately controlled.
It is foreseen that, in one case, the identification mark may be a serial number of the LED lamp, which may be set, or a serial number that is set by the electronic device according to the collected multiple luminescent images in the luminescent image.
In an optional embodiment, in order to obtain the plurality of light-emitting images and further obtain the luminance calibration information, a possible implementation manner is provided on the basis of fig. 1, please refer to fig. 3, and fig. 3 is a schematic flow chart of another lighting luminance control method provided in the embodiment of the present application. The above S200 may include:
s200a, acquiring a first image when the LED light-emitting system is monochromatic red light and the brightness is a preset gray scale.
S200b, acquiring a second image when the LED light-emitting system is monochromatic green light and the brightness is a preset gray scale.
S200c, acquiring a third image when the LED light-emitting system is monochromatic blue light and the brightness is a preset gray scale.
S200d, acquiring a fourth image when the LED light-emitting system is a three-color mixed light and the brightness is a preset gray scale.
It should be understood that the light-emitting images of the LED light-emitting system under the condition of different colors and preset gray scales are obtained, and the number of the photosensitive elements of the camera or the camera is digitized through the brightness analysis, so as to complete the collection of the light-emitting images and the brightness calibration information of the LED light-emitting system. It is anticipated that the above-mentioned sequence of acquiring the luminescence images may be other sequences, so as to acquire the luminescence images of the LED luminescence system under different conditions, and further acquire the luminance calibration information of the LED lamp.
For example, if the full brightness of the LED lighting system is 255 grayscales, the preset grayscale can be set to 127 grayscales. It should be understood that the process of acquiring the light-emitting image may be to control the camera or the camera to capture the corresponding image at regular time, for example, the electronic device sets a preset sequence (e.g. red, green, blue, and mixed) for the LED lighting system, emits light for a preset time (e.g. 2s), and controls the camera to capture the light-emitting image under different conditions, so as to store the light-emitting image for subsequent processing. In the process of acquiring the luminescence image, it is expected that a plurality of luminescence images in the same scene may be acquired, so as to obtain more accurate luminance calibration parameters.
It can be understood that, if the LED lighting system is an LED lamp ring, when a camera is used to collect a lighting image, a bracket may be used to fix the LED lamp ring, so as to keep the LED lamp ring and the camera lens parallel to each other, and ensure that a connection line between the center of the lamp ring and the center of the camera is perpendicular to the plane of the LED lamp ring, so as to ensure that the distances from each LED lamp to the camera in the obtained lighting image of the LED lamp are the same, and correct placement of the bracket can reduce lens distortion. It should be understood that the above is only one placement setting for collecting the luminescence images, and when the processing capability of the power equipment is sufficient, the power equipment can also process a plurality of luminescence images with different distances, so as to achieve the purpose of acquiring the brightness calibration information.
In an alternative embodiment, in order to control the LED lighting system to generate white balance light, on the basis of fig. 3, taking the three-color mixed light and the specified brightness as white balance light as an example, please refer to fig. 4, and fig. 4 is a flowchart of another method for controlling the brightness of the lamp light provided in this embodiment of the present application. The above S202 may include:
s202a, adjusting the LED light-emitting system to be white balance light according to the brightness calibration information.
It can be understood that, according to the brightness calibration information, the designated brightness is set as the white balance light, so that the brightness compensation information of the LED light-emitting system is not clear when the LED light-emitting system generates the white balance light, and then all the LED lamps are all turned on to the maximum power consumption, so as to save the power consumption of the LED light-emitting system.
It is anticipated that when a lighting system comprising a plurality of colored LED lamps is used, different colored LED lamps may be set to different colors and intensities of light to achieve the purpose of obtaining a light source with a specified brightness. For example, a light ring of 6 colored LED lights that alternately emit red, green, and blue lights in sequence, with a brightness of 127 gray levels, is perceived by a distant user as white balance light.
