In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. 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.
Fig. 1 is a flowchart of an embodiment of a method for adjusting partial transmittance of glasses according to the present invention, as shown in fig. 1, including the following steps:
step S11, determining the intensity of light passing through each set area of the front filter module of the glasses;
step S12, adjusting the transmittance of the setting area according to the intensity of the light passing through the setting area and the preset threshold range of the intensity of the light.
Preferably, the glasses contain a glasses frame, a lens, a front filter module, a camera module, and an image processing module, wherein: the spectacle frame consists of a left spectacle frame, a right spectacle frame and a bracket for connecting the left spectacle frame and the right spectacle frame; the front light filtering module is arranged in front of the lens and used for adjusting the light transmittance of each set area of the front light filtering module; the camera module is arranged at the central point position of the bracket and used for generating a real-time image; the image processing module is used for determining the light intensity entering the camera module through each set area of the front filtering module according to the real-time image generated by the camera module; and adjusting the light transmittance of the set area according to the light intensity passing through the set area and a preset light intensity threshold range.
In one preferred implementation of step S11,
preferably, a real-time image generated by a camera module arranged on the glasses bracket is processed to obtain the brightness of the image; and determining the light intensity of each set area passing through the pre-filtering module according to the corresponding relation between each set area of the pre-filtering module and the image.
The external light enters the camera module through the front light filtering module to form an image; the camera module generates a real-time image and transmits the real-time image to the image processing module; and after receiving the real-time image from the camera module, the image processing module processes the image.
Preferably, the camera is a wide-angle camera capable of collecting images in the entire field of view of a user wearing the glasses.
Wherein the prefilter module comprises: the liquid crystal display panel comprises an outer glass panel, an intermediate layer liquid crystal array and an inner glass panel. Each set area of the prefilter module corresponds to one or more liquid crystal pixels of a liquid crystal array of the prefilter module.
Preferably, each set region of the prefilter module corresponds to a liquid crystal pixel of a liquid crystal array of the prefilter module, so that accurate control of light transmittance can be realized.
Preferably, each setting area of the prefilter module corresponds to a plurality of liquid crystal pixels of a liquid crystal array of the prefilter module, and the fewer the liquid crystal pixels corresponding to each setting area, the higher the adjustment accuracy of the light transmittance, but the more calculation amount is increased accordingly. The setting area may be divided into N rows and M columns, which is more common.
Preferably, the corresponding relation between each set area of the prefiltering module and the image is determined according to an optical imaging principle. This is because, in an actual glare environment, the glare light source is far from the user wearing the glasses, and therefore, the position of the glare light source in the image corresponds to the position of the glare light source in the prefilter module.
The lens of the camera is generally arranged in a circular shape, and thus, the prefilter module is generally arranged according to the shape of the eyeglass lens. Preferably, a correspondence relationship between each set region of the prefilter module and a pixel of the image is set in advance. The light transmittance is adjusted from the pixel level to prevent excessive filtering from causing loss of picture information.
Preferably, if there are more liquid crystal pixels corresponding to each setting region, that is, the number of setting regions is small, the brightness of the pixel with the highest brightness in the image region corresponding to each setting region of the prefilter module is taken as the light intensity of each setting region of the prefilter module. This is to avoid that only some of the pixels in the image area corresponding to a single setting area have high luminance, and the luminance of the strong light cannot be reflected by averaging.

Preferably, the prefiltering module comprises: the liquid crystal display panel comprises an outer glass panel, an intermediate layer liquid crystal array and an inner glass panel; and the middle layer liquid crystal array changes the rotation state of liquid crystal molecules according to the determined target driving voltage of the liquid crystal array of the set area, so that the light transmittance of the liquid crystal array of the set area reaches the target light transmittance.
Preferably, the inner side of the outer glass panel is attached with a transparent electrode, and the inner side of the inner glass panel is attached with a switch array, a transparent row-column electrode wire and a transparent electrode. Liquid crystal molecules in the middle layer liquid crystal array sandwiched between the two layers of glass panels can change along with the change of field intensity between the two layers of electrodes, and the voltage of the transparent electrodes is controlled by the transparent leads in the row and column directions line by line; the specific progressive control mode is as follows: and the first row of electrodes are electrified, when the voltage reaches the starting threshold of the switch array in the first row, the transparent electrodes in the first row are conducted with the lead wires in the column direction, an electric field is generated between the transparent electrodes of the two layers of glass panels, liquid crystal molecules in the middle of the two layers of glass panels are sent and turned over, and the light transmittance is changed. Therefore, different voltage values of different positions of the switch array are set, namely the target driving voltage of the liquid crystal array in the set area is determined, so that liquid crystal molecules can be inverted to different degrees, and finally different light transmittance at different positions is achieved.
Preferably, the target transmittance of the set area is: (lower predetermined light intensity value + upper predetermined light intensity value) divided by (2) the light intensity passing through the predetermined region. The problem that the brightness of an image is reduced and the image cannot be automatically recovered when a strong light source disappears after the transmittance is reduced due to strong light is solved.
Preferably, manual adjustment of a user can be accepted, so that adjustment can be carried out according to different habits of different people, different overall control signals can be generated, and the overall filtering intensity can be adjusted.
Through this embodiment, carry out local luminousness to the prefiltering module and adjust, every setting region all is according to the light intensity that passes through this setting region to and the light intensity threshold value scope of presetting, should set for regional luminousness. Thereby being capable of avoiding the influence of strong light to adapt to the strong light environment, and the human eyes can still see the surrounding environment clearly. Specifically, the following beneficial effects are achieved:

The image brightness is analyzed by adopting an image processing method, so that a control signal is output, the cost is low, the real-time performance is better, and the maintenance is easy.
The control algorithm can be updated, different filtering rules are set according to different environment requirements, and the method is more suitable for the complexity of the wearing environment.
