Detailed Description
In order to make the objects, features and advantages of the present invention more apparent and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In order to solve the problem that the light effect of an atmosphere lamp in the related art is relatively single, a first embodiment of the present application provides an atmosphere lamp control method, which is specifically applied to a side-emitting optical fiber having an end provided with multiple light color adjustable light sources, and the atmosphere lamp is implemented by using an optical fiber, as shown in fig. 1, the optical fiber structure diagram provided in this embodiment is shown.
Fig. 2 is a schematic flow diagram of an atmosphere lamp control method provided in this embodiment, where the atmosphere lamp control method includes the following steps:
step 201, converting the atmosphere light effect indication data into a plurality of single-frame static images corresponding to different lighting periods.
Specifically, the atmosphere light effect indication data of the embodiment includes environment perception data and atmosphere light effect reference data. In practical applications, the environmental audio signal may be converted into a plurality of single-frame still images corresponding to different lighting periods according to sound frequency and/or amplitude information of the environmental audio signal; additionally, the mood light effect indication data may be a dynamic image (e.g., a water flow dynamic image), a video, or the like.
Step 202, respectively extracting image characteristic information of each single-frame static image, and mapping a first light-emitting effect parameter of the optical fiber changing along with a time domain based on the image characteristic information.
Specifically, the light-emitting effect parameters of the present embodiment include light intensity and chromaticity. In practical application, light-emitting effect information such as light intensity and chromaticity of a single-frame static image is extracted and mapped to each part of an optical fiber, and a time dimension mapping effect is obtained.
In some embodiments of this embodiment, the step of extracting the image feature information of each single frame of still image includes: equally dividing each light-emitting period into a plurality of variation periods; respectively aiming at the single-frame static image corresponding to each light-emitting time interval, acquiring multi-frame static images corresponding to a plurality of change time intervals; and respectively extracting image characteristic information corresponding to the multiple frames of static images.
Specifically, in this embodiment, in order to achieve a more realistic lighting effect of the atmosphere lamp, each lighting period may be further subdivided into a plurality of variation periods, taking a single lighting period as 1 second as an example, 1 second may be divided into 20 variation periods, and then a lighting effect of one frame is subsequently fitted through a plurality of static images of a single period.
And 203, acquiring a second light-emitting effect parameter of the optical fiber by adopting the spectral information of the multi-light-color adjustable light source and combining a preset light attenuation function and a preset color synthesis function.
Specifically, in this embodiment, parameter fitting is performed through a light attenuation function and a color synthesis function to form a control function of the multi-light source changing along with the time domain, that is, corresponding light intensity and chromaticity can be obtained according to spectral information emitted by the optical fiber, the light intensity information is input to the light attenuation function to obtain the light intensity attenuated in the length direction of the optical fiber, then the chromaticity information is synthesized through the color synthesis function to obtain the chromaticity at each position in the length direction of the optical fiber, and the light intensity obtained through the light attenuation function and the chromaticity obtained through the color synthesis function constitute a second light emission effect parameter.
In this embodiment, the light attenuation function can be expressed as: i ═ I0·e-a·dWherein I represents the intensity of light after attenuation, I0Denotes initial light intensity, e denotes a natural constant, d denotes light penetration depth, and a denotes light absorption coefficient. In practical applications, the coefficients in the formula can be influenced according to the density of the optical fiber and the corresponding material and optical characteristics of the side emission.
Further, it is considered that the physical properties of the optical fiber in practical use are influenced by the manufacturing processThe present embodiment may take the consideration of the physical properties of the optical fiber into consideration in the optical attenuation function to eliminate the error introduced by the physical properties of the optical fiber and improve the accuracy of the optical attenuation function, and accordingly, the optical attenuation function of the present embodiment may also be expressed as: i ═ k · I0·e-a·dWherein I represents the light intensity after attenuation, k represents the modification coefficient of the physical property of the optical fiber, and I0Denotes initial light intensity, e denotes a natural constant, d denotes light penetration depth, and a denotes light absorption coefficient. It should be understood that the optical fiber physical property correction coefficient of the present embodiment may include one or more of an optical fiber material characteristic correction coefficient, an optical fiber structure characteristic correction coefficient, and the like, and when the optical fiber physical property correction coefficient takes into consideration a plurality of different types of coefficients at the same time, it may be expressed as k ═ α k1+βk2+…γknWherein k is1,k2…knThe correction coefficients of the physical properties of the optical fibers of different types are respectively expressed, and alpha and beta … gamma respectively express the weighting coefficients corresponding to the correction coefficients of the physical properties of the optical fibers of different types.
It should also be noted that the color composition function of the present embodiment is a CIE colorimetry system, such as the CIE1931 colorimetry system.
And 204, matching the second light-emitting effect parameter with the first light-emitting effect parameter to obtain a time-domain change control function of the multi-color adjustable light source.
Specifically, in this embodiment, the obtained second light-emitting effect parameter may be matched with the first light-emitting effect parameter by using a least square method or other computer algorithms, so as to control an error, and form a single-frame simulation effect control parameter.
In an optional implementation manner of this embodiment, the step of matching the second light-emitting effect parameter with the first light-emitting effect parameter includes: selecting part of first luminous effect parameters from all the first luminous effect parameters according to preset parameter characteristics; and matching the second light-emitting effect parameter with part of the first light-emitting effect parameters.
Specifically, in practical application, all the first light-emitting effect parameters can be matched, however, in consideration of the fact that the data volume is large and all the data can not guarantee high effectiveness, in this embodiment, only part of the characteristic parameters are selected from all the first light-emitting effect parameters to be matched, the characteristic parameters can form effective reference for light-emitting control, and the data volume processed by the light-emitting control is reduced while the accuracy of the light-emitting control is guaranteed.
And step 205, controlling the multi-light-color adjustable light source by referring to the control function changing along with the time domain.
Specifically, in practical application, the light source light emission control of this embodiment may be single-ended control of a multi-light-color tunable light source at one end of an optical fiber, or double-ended control of a multi-light-color tunable light source at two ends of an optical fiber at the same time, where light mixing at two ends can form a differentiated light mixing change effect in the optical fiber, so as to further enrich the diversity of the light emission effect of the optical fiber, as shown in fig. 3, an overall optical fiber light distribution diagram provided by this embodiment corresponds to an application scenario where light intensities at two ends (i.e., an end a and an end B) of the optical fiber are consistent, as shown in fig. 4, another overall optical fiber light distribution diagram provided by this embodiment corresponds to an application scenario where light intensities at two ends of the optical fiber are inconsistent. Based on the double-end multi-color light source of this embodiment, through time domain control intensity, can form full-color atmosphere lamp and change the effect.
Further, in an optional implementation manner of this embodiment, after the step of controlling the multi-light-color tunable light source by referring to the time-domain-varying control function, the method further includes: acquiring actual light-emitting effect parameters of the optical fibers; the actual lighting effect parameter is compared with the expected lighting effect parameter.
Correspondingly, when the actual light-emitting effect parameter exceeds the preset error range, the equal number of the light-emitting periods is increased, and then the step of equally dividing each light-emitting period into a plurality of variation periods is executed.
Specifically, in practical application, the actual light emitting effect of the optical fiber may be unexpected when the light emitting control is performed according to the control logic, so that in order to improve the light emitting effect, a single frame of static image may be divided into more frames of static images, so as to simulate the single frame effect, and then a corresponding control function changing along with a time domain is regenerated, and the light emitting control is performed again, so as to implement dynamic correction of the light emitting effect of the optical fiber.
The present embodiment is described by taking a dynamic effect of simulating water flow as an example, different frame presentation effects in a dynamic region may be formed first, each frame effect is mapped to a corresponding length portion of an optical fiber (i.e., an optical fiber portion in a different distance interval with respect to a light source in a length direction), light intensity and chromaticity characteristic information that changes with time domain is extracted, and then a light color synthesis effect of the light sources at two ends of the optical fiber is adjusted to form a light emitting effect that changes regularly with time in a water color interval. It should be noted that the present embodiment forms a multi-frame variation effect in a single period (for example, 1 second) for each frame of water flow information, for example, divides 1 second into 20 variation periods, controls the light emission intensity, fits one frame of water flow image information, and forms a more realistic light emission effect as much as possible.
Based on the technical scheme of the embodiment of the application, the atmosphere lamp effect indication data are converted into a plurality of single-frame static images corresponding to different lighting periods; respectively extracting image characteristic information of each single-frame static image, and mapping a first luminous effect parameter of the optical fiber changing along with a time domain based on the image characteristic information; acquiring a second light-emitting effect parameter of the optical fiber by adopting spectral information of the multi-light-color adjustable light source and combining a preset light attenuation function and a preset color synthesis function; matching the second light-emitting effect parameter with the first light-emitting effect parameter to obtain a time domain change control function of the multi-light color adjustable light source; and controlling the multi-light-color adjustable light source by referring to the control function changing along with the time domain. By implementing the scheme, the light source is controlled to emit light at any time domain, so that the change effect of the full-color atmosphere lamp can be formed; the light source spectrum composition is adjusted to simulate the full spectrum light source effect, and a functional lighting use light source is formed; the light source control function can be adaptively generated through environment signal perception to control light emission, and more diversified light effects are guaranteed.
