In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following description will be made with reference to the accompanying drawings. It is obvious that the drawings in the following description are only some examples of the invention, and that for a person skilled in the art, other drawings and embodiments can be derived from them without inventive effort.
One embodiment of the present invention, as shown in fig. 1, is a method for eliminating illumination shadows based on an auxiliary light source, comprising:
s100, acquiring a starting instruction, and starting a main lamp source according to the starting instruction;
specifically, when the user learns that the ambient light is darker, or when the user needs to open the intelligent device and throw light on, send the opening instruction to the intelligent device. After the intelligent device obtains the starting instruction, the main lamp source of the intelligent device is started, and a light source is provided for the user to learn. The main light source of the intelligent device is a light source arranged in a lampshade above the intelligent device.
The intelligent device is a device which is similar to an intelligent desk lamp and used for providing illumination for a user, and comprises a base, a connecting rod and an illuminating device, wherein the connecting rod is connected with the base and the illuminating device, the illuminating device comprises a main lamp source, and an auxiliary lamp source is arranged on the connecting rod and can freely move on the connecting rod. As shown in fig. 2, a schematic diagram of an intelligent desk lamp (an auxiliary light source is not shown) of one of the intelligent devices includes a lighting device 1, a connecting rod 2 and a base 3, which are only used for facilitating understanding of the structure of the intelligent device, but in practice, the intelligent desk lamp is not limited to the one shown in the schematic diagram.
In addition, because the current light intensity of the learning environment where the external user is located is different, the corresponding light intensity levels required for turning on the main light source are also different. The intelligent device externally arranged on the body and used for controlling the mechanical device for turning on and off the main lamp source can be used for setting light intensity levels of different gears corresponding to different main lamp sources, and a user can manually adjust the intelligent device. Also can dispose light intensity inductor by intelligent device, according to the external environment light intensity that senses, combine external environment light intensity and the corresponding mapping table of lamp source light intensity, select suitable lamp source light intensity.
S200, after the main light source is turned on, acquiring a learning picture;
specifically, after all light source light beads of the intelligent device are turned on, the camera is synchronously turned on to obtain a learning picture, and the learning picture comprises all positions where shadows are likely to be generated in a learning area of a user. The positions and the number of the cameras are also not particularly limited.
The camera can be set up in the optional part of intelligent device, can be close with the position of main lamp source, for example, place the camera near main lamp source. Or the camera is placed at any position of the connecting rod of the intelligent device, or the camera is arranged on a flexible support with an extensible adjustable position, and the position of the camera can be automatically adjusted by the intelligent device or manually adjusted by a user.
S300, when the shadow exists in the learning picture, calculating the shadow angle of the shadow;
specifically, when the shadow exists in the obtained learning picture, it is shown that the region is shielded by the user or other objects, and enough light is not provided for the user to check and learn, so that the user needs to adjust the sitting posture to look down, on one hand, the sitting posture is incorrect, the spine is affected, and on the other hand, the eyes are too close to the desktop, and the influence on the eyesight is bad.
Therefore, the shadow angle of the shadow in the learning picture is calculated by combining the position relation of the main light source, the camera and the shielding object, so that the light intensity of the shielded part is judged, and in the same learning picture, the farther the shadow area is away from the edge of the shielding object, the smaller the shadow angle is, and the weaker the light intensity is.
For example, when the main light source is above the head of the user, the head of the user may block part of the light emitted from the light source light bead, and the rest of the main light source light is less irradiated, so as to form a shadow area, and the user is the blocking object. And judging a shadow angle formed by combining the position of each point in the shadow area with the position of the camera and the edge of the shielding object according to the position of the main light source and the light irradiation direction and combining the edge of the shielding object.
S400, acquiring user information, and acquiring preset standard brightness according to the user information;
specifically, user information of a user who is currently using the smart device, that is, identity information such as age and sex of the user is acquired. For example, each user needs to enter his or her own identity information, including but not limited to sex, age, facial head portrait, fingerprint, etc., when the smart device is turned on for use, the facial head portrait of the user is obtained by the camera for analysis, and then is matched with the identity information collected in the previous period, so as to determine the user information of the user. Then, a preset standard brightness is obtained according to the user information, for example, the optimum illumination brightness of the user under the age and gender corresponding to the user information is obtained as the preset standard brightness.
S500, calculating the position of an auxiliary lamp source of the auxiliary lamp source according to the shadow angle;
specifically, the position of the auxiliary light source is calculated according to the shadow angle, and when the position of the auxiliary light source needs to be supplemented with light, the position of the auxiliary light source on the connecting rod is determined by the position of the learning plane of the user. For example, when a user draws on a desk, the learning plane is the desk top, but when the user browses materials such as dictionary, the learning plane is the material paper, and due to the thickness of the materials themselves, if the materials are all learned on the desk, the learning plane of the latter is higher than the learning plane of the former, and the corresponding auxiliary light source position should be higher than the former.
S600, calculating the brightness level of the auxiliary light source according to the shadow angle and the preset standard brightness;
specifically, for the brightness levels, even if all the shadow areas are shaded, the shading depth degree between the shadow areas has an influence on light supplement, the brightness level of the area with the darker shade requiring light supplement is higher, and the brightness level of the area with the lighter shade requiring light supplement is lower. And analyzing the corresponding brightness grade needing light supplement according to the preset standard brightness, so that the environment brightness after light supplement reaches the optimum brightness which can be accepted by the user using the intelligent device at present.
S700, acquiring a user operation instruction;
s800, adjusting the auxiliary light source to the position of the auxiliary light source according to the user operation instruction, and adjusting the auxiliary light source according to the brightness level.
Specifically, a user operation instruction is obtained, the auxiliary light source is adjusted to the analyzed position of the auxiliary light source, the auxiliary light source is started, and the brightness of the auxiliary light source is adjusted according to the calculated brightness level. After adjustment, a new learning picture can be obtained, if the learning picture does not have a shadow any more, the light supplement scheme is shown to achieve the effect, and if the shadow still exists, the adjustment is carried out again. In addition, the status of the user is detected if the user status changes, such as sitting. And if the head position and the like are changed, the learning picture is obtained again to adjust the light supplement scheme.
In the embodiment, the position of the auxiliary lamp source is analyzed by learning the shadow angle of the shadow in the picture, and then the brightness level of the auxiliary lamp source is determined by combining the preset standard brightness, so that the light is supplemented to the shadow area in a targeted manner, and the brightness of the environment after light supplementation is suitable for the current user.
Another embodiment of the present invention is a preferable embodiment of the above-mentioned embodiment, as shown in fig. 3, including:
s010 obtains environment brightness information;
s020 sending the starting instruction when the ambient brightness information is less than or equal to the preset brightness; and/or the presence of a gas in the gas,
specifically, the intelligent device acquires the ambient brightness information of the current ambient environment, compares the ambient brightness information with the preset brightness, and when the ambient brightness information is less than or equal to the preset brightness, it indicates that the current ambient environment is too dark, and if the user continues to learn under such a condition, adverse effects are caused to the eyesight, so that an opening instruction is sent.
The preset brightness is obtained based on analysis statistics, and the user learns in an environment lower than the preset brightness, which results in the pupils of the eyes. The abnormal contraction of ciliary muscle and other parts can cause eye fatigue and myopia and other adverse consequences.
In addition, the intelligent device does not acquire the ambient brightness information of the current surrounding environment all the time, and the ambient brightness information can be acquired at regular intervals in consideration of energy saving and other factors. Moreover, the precondition for turning on the desk lamp is that a user is learning in the current environment, and then the desk lamp needs to be turned on when the current surrounding environment is too dark. Therefore, before the ambient brightness information is acquired, whether a user is learning or not can be detected through the sensor, and if so, the ambient brightness information is further acquired.
S030 acquires user voice information;
s040, when the user voice information contains a keyword, the opening instruction is sent; and/or the presence of a gas in the gas,
specifically, the voice information of the user is obtained, the voice information of the user is identified, and when the voice information of the user contains a keyword, an opening instruction is sent. For example, the user says "turn on the desk lamp", and when the desk lamp detects keywords such as "turn on", "desk lamp", etc., a turn-on instruction is sent.
The keywords may be set in an early stage based on the user's requirement, such as "turn on", "desk lamp", "lamp", and a series of words with similar meanings that indicate to turn on the smart device. In addition, the related keywords should be included as comprehensively as possible in consideration of the influence of the accents, dialects, and other factors of the users in different areas and the language.
S050 obtaining user operation information and sending the opening instruction according to the operation information;
specifically, user operation information is acquired, and a start instruction is sent according to the operation information. The specific type of the user operation information depends on the on mode of the intelligent device, for example, if the intelligent device body is provided with a key button or the like for controlling the on/off of the light source, the user operation information is the change of the control device.
