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 lighting shadows based on a user picture, 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 is 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, and the illuminating device comprises an auxiliary lamp source. 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.
The intelligent device obtains the mode of opening the instruction diversified, and comparatively traditional mode has the mechanical device that the control was opened and is closed main lamp source on for the intelligent device body, can be the form of button, also can be the form of touch. Secondly, a voice control mode may also be adopted, for example, when the user says "turn on the desk lamp", and when the intelligent device detects keywords such as "turn on", "desk lamp", etc., it is equivalent to acquiring a turn-on instruction. In addition, the intelligent device can be in an induction control mode, similar to a faucet capable of automatically discharging water in an induction mode, and when a user places a handle or other objects in a preset induction area and the intelligent device senses the existence of the user, the main light source is turned on. Or when the intelligent device detects that the learning environment is low in brightness and detects that a user is learning, the intelligent device is required to provide illumination. The light source light bulb is turned on, for example, a sensor senses that a user is continuously present near the smart device for a certain period of time.
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 lamp source is turned on, obtaining a user picture;
specifically, after a main light source of the intelligent device is started, a camera is synchronously started to obtain a user picture, the user picture comprises a user and the surrounding environment of the user, the user direction in the user picture is convenient to identify subsequently, all positions which possibly generate shadows in a learning area of the user are also included, and the shadow in the user picture is convenient to identify subsequently and the shadow angle is convenient to analyze. Therefore, the number and the obtaining mode of the user pictures are not limited, and the positions and the number of the cameras arranged on the intelligent device are also not specifically 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 user picture, identifying the user direction according to the user picture;
specifically, when the shadow exists in the obtained user picture, it is indicated 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 may need to adjust the sitting posture to look down, and therefore, on one hand, the sitting posture of the user is incorrect, the spine and the like are affected, and on the other hand, the eyes are too close to the desktop, and the influence on the eyesight is bad. Therefore, light needs to be supplemented to the shadow area.
However, in order to reduce unnecessary calculation processes, before analyzing the light supplement adjustment scheme, it is determined whether the shadow in the user picture affects the learning of the user, if so, the shadow is defined as an effective shadow, and then the subsequent calculation of the light supplement scheme is continued. If the study of the user cannot be influenced, light supplement is not needed.
For example, a part of books are stacked far away from the learning area of the user, and the books form a shadow under the irradiation of the light beads of the main light source, but the analysis of the picture of the user can lead the shadow to be completely irrelevant to the learning area of the user and not to influence the learning of the user, so the shadow is not an effective shadow area, and the shadow is not required to be supplemented with light.
If the effective shadow needs to be supplemented with light, the user direction needs to be identified firstly. Because the learning habits of each user are different, the relative positions of the user and the intelligent device are possibly different during each learning, and particularly, when the learning area is large and the number of the intelligent devices is small, if an auxiliary light source arranged on the connecting rod is required to supplement light for the learning area of the user, the direction of the user needs to be determined.
And identifying the user direction according to the acquired user picture, wherein the user direction is the direction of the user relative to the intelligent device, the user picture comprises the user and the surrounding environment thereof, and the user direction is analyzed and obtained by combining the acquired direction of the surrounding environment relative to the intelligent device.
S400, adjusting the auxiliary light source direction of the auxiliary light source according to the user direction;
specifically, the auxiliary light source direction of the auxiliary light source is determined according to the user direction, and the auxiliary light source is adjusted to the auxiliary light source direction. That is, the irradiation direction of the auxiliary light source is adjusted to face the user direction, so that the light of the auxiliary light source can be directly irradiated to the user direction.
The auxiliary light source is arranged on the connecting rod of the intelligent device, can freely slide up and down along the direction of the connecting rod, can freely rotate by taking the connecting rod as a center, and can stably stand at any position of the connecting rod for light supplement.
For example, the user's picture is analyzed, and the user is studying on the left half of the desk by using the desk as a reference, so that if the auxiliary light source needs to supplement light, the auxiliary light source needs to be adjusted to face the left half of the desk.
S500, calculating a shadow angle of the shadow according to the user picture, and calculating an auxiliary light source position and a brightness level of the auxiliary light source according to the shadow angle;
specifically, the shadow angle of the shadow in the user picture is calculated according to the obtained user picture, and then the position and the brightness level of the auxiliary light source are calculated according to the shadow angle. The position of the auxiliary light source is the position of the auxiliary light source on the connecting rod when the auxiliary light source is needed to supplement light, and the position is determined by the position of the learning plane of a 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.
For the brightness levels, even if all the shadow areas are shaded, the shading depth degree between the shadow areas has influence on light supplement, the brightness level of the area with the darker shade needing light supplement is higher, and the brightness level of the area with the lighter shade needing light supplement is lower.
Therefore, the user picture is used for analyzing the shielding object causing the shadow, and then the shadow angle of the shadow in the user picture is calculated by combining the position relation of the main lamp source, the camera and the shielding object, so that the light intensity of the shielded part is judged, and the corresponding brightness level needing light supplement is analyzed. In the same user picture, the farther the shadow area is from the edge of the obstruction, 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 can block part of light emitted by the main light source, and the rest of the light which is not blocked and irradiated into the user is less, so that a shadow area is formed, and the user is a blocking object at this time. 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 lamp source and the light irradiation direction and combining the edge of the shielding object.
S600, adjusting the auxiliary light source according to the position of the auxiliary light source and the brightness level.
Specifically, the auxiliary light source is adjusted to the auxiliary light source position obtained through analysis, the auxiliary light source is started, and the brightness of the auxiliary light source is adjusted to the brightness level determined through calculation.
In this embodiment, the auxiliary light source is arranged on the connecting rod of the intelligent device, and the auxiliary light source is specifically adjusted by analyzing the acquired user picture and determining the light supplement scheme according to the user picture, so that the purpose of eliminating the shadow is achieved.
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 obtaining human body induction information when the environment brightness information is less than or equal to the preset brightness information;
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. However, it is necessary to further analyze whether a user is learning in the current environment, and if so, the smart device needs to be turned on. Thus, the human body sensing information is acquired.
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.
S030 analyzing the human body induction information;
s040 sends a starting instruction when the distance between the user and the intelligent device is analyzed to be smaller than or equal to a preset distance;
specifically, the acquired human body sensing information is analyzed, the intelligent device can sense whether a user exists through an infrared sensor, a human body sensor and the like, if so, the distance between the existing user and the intelligent device and the stay time of the user are further judged, and only if the distance between the user and the intelligent device is smaller than or equal to a preset distance, the situation that the user is near the intelligent device currently is shown, and the situation that the user stays in the range for a preset time length, the situation that the user is learning or working currently is shown, and then an opening instruction is sent. Therefore, the situation that the intelligent device is started to waste resources when the user only stops for a short time or is not near the intelligent device is avoided.
