The lens parameter adjusting method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Referring to fig. 1, an embodiment of the present application provides a method for adjusting parameters of a lens, optionally, the method may be applied to glasses, where the glasses may be wearable devices, and the method includes:
Wherein the target image comprises a periocular region of the user's eyewear; the periocular region, i.e., the area around the lens; optionally, a camera may be arranged on the glasses, and the image of the user is acquired through the camera, and facial recognition is performed to obtain the eyes of the user; then, the area around the eye, which is a predetermined distance range from the center of the eyeball, is used as the periocular area. As a first example, referring to fig. 2, a portion between a broken-line frame S1 and a broken-line frame S2 in fig. 2 is a periocular region.
After the periocular region is determined, extracting a periocular image corresponding to the periocular region in the target image; that is, the periocular image is an image of the periocular region in the target image.
It is understood that, in the embodiment of the present application, the user refers to a user wearing the eyeglasses.
Dividing the eye periphery image into a plurality of sub-regions so as to improve the accuracy of adjusting the parameters of the lens; optionally, in the process of the molecular region, a preset number of pixel points may be used as one sub-region, the eye periphery image is divided into a plurality of sub-regions, and brightness parameters are respectively determined; specifically, the brightness parameter is brightness of the sub-region, and brightness is also called brightness, which is how bright a color is. Lightness is one of three elements (hue, lightness and saturation) of color, and different colors have difference of light and shade, and the same color also has change of light and shade, for example, various colored objects generate light and shade of color due to difference of reflected light quantity of the colored objects. For eyes, areas affecting the appearance, such as dark circles and various pigmentation, are common; therefore, the brightness parameter of each sub-region in the periocular image is determined to determine whether the sub-region has a condition that affects the appearance.
After determining the brightness parameters of each sub-area, adjusting the lens parameters of the target lens area of the glasses corresponding to the sub-area based on the brightness parameters of all the sub-areas. The transparency is the transparency of the lens, and the brightness is the color brightness of the light source of the glasses.
For example, a corresponding relationship is preset, the corresponding relationship includes a target parameter value corresponding to each brightness value, and the lens parameters of the lens area are adjusted to the target parameter values; for example, taking the example that the lens parameter includes transparency, after determining the brightness parameter, according to the correspondence, a target transparency value corresponding to the brightness parameter is determined, and then the transparency of the lens area corresponding to the sub-area is adjusted to the target transparency value.
The parameters of the lenses are adjusted through the brightness parameters, so that the aesthetic degree of the intelligent glasses is improved; for example, by adjusting the parameters of the lens, the technical effect of covering the eye shadow on the eyelid of the user is achieved; or the technical effect of removing black eyes.
In the embodiment of the application, a target image comprising a periocular region of eyes of a user is obtained, and a periocular image corresponding to the periocular region in the target image is extracted; according to the brightness parameters, the lens parameters of the target lens area of the glasses corresponding to the sub-area are adjusted, brightness difference with other sub-areas is offset, and the attractiveness of the glasses worn by a user is improved. The embodiment of the application solves the problem that in the prior art, the appearance of the intelligent glasses is usually single.
Optionally, in this embodiment of the application, the step of adjusting the lens parameter of the target lens area of the glasses corresponding to the sub-area according to the brightness parameter includes:
determining brightness parameters of each sub-region in the periocular image;
determining a target parameter of the periocular image according to the brightness parameter;
and adjusting the lens parameters of the target lens area of the glasses corresponding to the sub-area according to the target parameters and the brightness parameters.
Wherein the target parameter is used for evaluating the brightness of the whole periocular image; alternatively, the target parameter may be a mean or median of all the brightness parameters, or the like.
After determining the target parameter and the brightness parameter, for each sub-area, adjusting the lens parameter of the target lens area based on the difference between the brightness parameter of the sub-area and the target parameter; the target lens area is a lens part corresponding to the subarea in the lens; for example, for a first sub-area of the sub-areas, a portion of the lens corresponding to the first sub-area is a first lens area, and the lens parameter of the first lens area is adjusted according to a difference between the brightness parameter of the first lens area and the target parameter.
The lens parameters include at least one of transparency and brightness. When the lens parameter comprises transparency, for sub-regions having brightness lower than the target parameter, the transparency of the target lens region may be increased; otherwise, the brightness is reduced, so that the brightness around the eyes of the user can be balanced; for example, if the user has a black eye around the user's eyes, and the brightness of the sub-region of the black eye is lower than that of the other sub-regions, the transparency of the sub-region of the black eye is increased to offset the brightness difference with the other sub-regions, so as to eliminate the visual effect of the black eye, thereby playing the effect of hiding the black eye, and improving the aesthetic degree of the user wearing the glasses.
When the lens parameters include brightness, taking the black eye sub-area as an example, the brightness of the target lens area can be increased for the sub-area with brightness lower than the target parameter; otherwise, the brightness is reduced, so that the brightness around the eyes of the user can be balanced; for example, if the user has black eyes around the eyes, and the brightness of the black eye sub-region is lower than that of the other sub-regions, the brightness difference between the black eye sub-region and the other sub-regions is offset by increasing the brightness of the black eye sub-region, so as to achieve the effect of hiding the black eyes.
In an optional embodiment, a camera module is arranged on one side of the glasses facing the face of the user;
the step of acquiring an image comprising a periocular region of a user's eye comprises:
through the camera module, gather the image including the periocular region of user's eyes.
As a second example, as shown in fig. 3, a camera module C is disposed on a side of the glasses G facing the face of the user, and the camera module C is configured to collect images of the eye circumference area of the eyes of the user, so as to obtain the eye circumference images of the eye circumference area of the user in real time, and improve the wearing beauty in real time by adjusting the lens parameters.
In an alternative embodiment, where the lens parameter comprises the transparency,
the step of adjusting the lens parameters of the target lens area of the glasses corresponding to the sub-area according to the brightness parameters includes:
determining a first brightness difference value between the brightness parameter and the target parameter;
determining a first transparency adjustment value corresponding to the first brightness difference value according to a preset corresponding relation between the brightness difference value and the transparency adjustment value;
and adjusting the transparency of the target lens area of the glasses corresponding to the sub-area according to the first transparency adjustment value.
The preset corresponding relationship includes a corresponding relationship between each brightness difference value and the transparency adjustment value. The brightness difference is obtained by subtracting the target parameter from the brightness parameter, and therefore, the brightness difference may be a positive number or a negative number, and therefore, the brightness differences having the same absolute value in the corresponding relationship have different transparency adjustment values.
The transparency adjustment value is used for adjusting the transparency of the target lens area so as to adjust the brightness of the sub-area and reduce the brightness difference between the brightness parameter of the sub-area and the target parameter. For the case that the brightness difference value is negative, namely the brightness is lower than the sub-area of the target parameter, the transparency adjustment value is positive number to increase the transparency of the target lens area; otherwise, the transparency adjustment value is a negative number so as to reduce the transparency of the target lens area and realize the brightness balance around the eyes of the user; for example, if the user has a black eye around the user's eyes, and the brightness of the sub-region of the black eye is lower than that of the other sub-regions, the transparency of the sub-region of the black eye is increased to offset the brightness difference with the other sub-regions, so as to eliminate the visual effect of the black eye, thereby playing the effect of hiding the black eye, and improving the aesthetic degree of the user wearing the glasses.
As a third example, taking the elimination of the black eye as an example, the lens parameter adjusting method provided in the embodiment of the present application includes the following steps:
in step 401, the eyewear identifies a user's periocular image.
When the glasses detect that the wearer starts to use the glasses, the micro-camera (camera module) collects the periocular images of the wearer.
According to the periocular image, firstly, the outline of the eye is identified, and then the color brightness of the periocular is calculated through a preset algorithm.
The brightness value range is between 0 and 1, 0 is the place with the lowest brightness, 1 is the place with the highest brightness, and the average value of the brightness is calculated and is used as the target parameter.
And determining a transparency adjustment value of the lens area of the corresponding lens according to the brightness difference value of each subarea, and adjusting the lens area according to the transparency adjustment value.
Optionally, the lens may be a Light Emitting Diode (LED), and in the process of adjusting the transparency, different electric fields may be set for different areas of the liquid crystal lens according to different transparency adjustment values, so as to increase the transparency of the lens correspondingly in an area where the brightness is lower than the average value, and conversely, decrease the transparency, balance the brightness around the eye of the wearer, and achieve the technical effect of hiding the black eye.
In an alternative embodiment, where the lens parameter comprises the brightness,
the step of adjusting the lens parameters of the target lens area of the glasses corresponding to the sub-area according to the brightness parameters comprises:
determining reference brightness of a reference sub-region corresponding to the target parameter in the sub-region;
if the brightness parameter of the sub-area is lower than the target parameter, adjusting the brightness of the target lens area of the glasses corresponding to the sub-area to the reference brightness.
The reference sub-region is a sub-region with brightness parameters closest to the target parameters; determining reference brightness of a reference sub-area, and for the sub-area with brightness parameters lower than the target parameters, adjusting the brightness of a target lens area of the glasses corresponding to the sub-area to be the reference brightness; that is, the sub-region closest to the target parameter is selected as the standard region, and the brightness of the sub-region with brightness lower than that of the standard region is adjusted to the brightness of the standard region to balance the brightness around the eyes of the user; for example, if the user has black eyes around the eyes, and the brightness of the black eye sub-region is lower than that of the other sub-regions, the brightness difference between the black eye sub-region and the other sub-regions is offset by increasing the brightness of the black eye sub-region, so as to achieve the effect of hiding the black eyes.
Taking the example of eliminating the dark eye circles, for the sub-area with brightness lower than the target parameter, the lens area corresponding to the lens emits light with specified brightness, and the specified brightness is the reference brightness of the reference sub-area; thus, the lower the brightness, the brighter the light emitted from the lens, thereby achieving the effect of hiding the dark circles.
In an optional embodiment, the method further comprises:
identifying a target sub-region of the sub-regions; target sub-areas such as eyelid areas, eyelash areas, etc.;
determining preset lens parameters corresponding to the target subarea; the preset lens parameters may include a preset value for each lens parameter; the lens parameters can also comprise the color of the LED light source and the like besides the transparency and the brightness;
controlling the lens parameters of the target lens area of the glasses corresponding to the target subarea to be the preset lens parameters so as to improve the aesthetic degree of wearing the glasses; for example, if the target sub-area includes an eyelid area, the lens parameters include light of a preset color, and the light of the eye shadow color is emitted through the LED light source, so that the technical effect of presenting the eye shadow when the user wears the eye shadow is achieved, and the wearing aesthetic degree is improved.
In the embodiment of the application, a target image comprising a periocular region of eyes of a user is obtained, and a periocular image corresponding to the periocular region in the target image is extracted; determining brightness parameters of each sub-region in the periocular image; according to the brightness parameters, the lens parameters of the target lens area of the glasses corresponding to the sub-area are adjusted, brightness difference with other sub-areas is offset, and the attractiveness of the glasses worn by a user is improved.
