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.
The invention realizes the automatic adjustment of the illumination angle of the lamp source of the intelligent desk lamp, so that the lamp source of the intelligent desk lamp is required to have a movable mechanical structure, thereby realizing the adjustment of the illumination angle.
For example: the lamp source of intelligence desk lamp is the annular, and the link on the lamp source is connected on the rotation axis that can adjust from top to bottom, left and right, realizes adjusting the illumination angle of lamp source through the angle of adjusting the rotation axis.
Fig. 1 shows a flowchart of an implementation of a method for adjusting an illumination angle according to the present invention, where the method for adjusting an illumination angle can be applied to an intelligent desk lamp, and the method for adjusting an illumination angle includes the following steps:
s101, when the illumination angle adjusting instruction is received, whether the illumination angle adjusting instruction is clear or not is analyzed.
Specifically, the user may send the illumination angle adjustment instruction through voice, or may send the illumination angle adjustment instruction through other manners, for example: the illumination angle adjustment instruction is sent by a mobile phone, or sent by a related sending area with the illumination angle adjustment instruction on the intelligent desk lamp (for example, a related button is pressed, and the intelligent desk lamp receives the illumination angle adjustment instruction by default).
The illumination angle adjustment command may be a command for only adjustment, and may include a detailed adjustment information command without specific adjustment information. The intelligent desk lamp judges whether the adjustment information contained in the illumination angle adjustment instruction is clear or not.
Optionally, the step S101 of analyzing whether the illumination angle adjustment instruction is clear specifically includes the following steps:
when the illumination angle adjusting instruction does not contain angle information, the illumination angle adjusting instruction is not clear;
and when the illumination angle adjusting instruction contains angle information, the illumination angle adjusting instruction is clear, and the illumination angle of the lamp source is adjusted according to the angle information.
Specifically, the angle information is basic information that needs to be known when the illumination angle of the lamp source is adjusted by the intelligent desk lamp, and if the illumination angle adjustment instruction does not contain the angle information, the intelligent desk lamp cannot clearly adjust the lamp source, so that the illumination angle adjustment instruction that does not contain the angle information is considered to be unclear, and the help of a subsequent camera is needed.
For example: the user voice says 'help me adjust the illumination angle' to the intelligent desk lamp, this sentence is equivalent to the illumination angle adjustment instruction, but the illumination angle adjustment instruction does not contain specific angle information, so the intelligent desk lamp thinks it is unclear.
For another example: the user presses a feature key (the key is an input trigger key of the illumination angle adjusting instruction) on the intelligent desk lamp, the intelligent desk lamp considers that the illumination angle adjusting instruction is received, but the illumination angle adjusting instruction only enables the intelligent desk lamp to adjust the lamp source and does not contain specific angle information, and therefore the intelligent desk lamp considers that the intelligent desk lamp is unclear.
For another example: the mobile phone (terminal equipment such as a tablet computer) of a user is in communication connection with the intelligent desk lamp, the user inputs '15 degrees left adjustment of the light source' on the mobile phone and sends the light source to the intelligent desk lamp, the intelligent desk lamp considers that the intelligent desk lamp receives an illumination angle adjustment instruction input by the user, and '15 degrees left' is angle information, so that the illumination angle adjustment instruction contains the angle information, the intelligent desk lamp considers that the illumination angle adjustment instruction is clear and can directly adjust the light source according to the illumination angle adjustment instruction, and in the example, the light source is adjusted 15 degrees left.
It should be noted that when a voice sending instruction is adopted, specific voice content is not limited in form, and the intelligent desk lamp can understand the specific meaning of the illumination angle adjusting instruction through voice recognition and semantic analysis to judge whether the instruction is clear or not.
And S102, if the illumination angle adjusting instruction is not clear, acquiring a user image through the camera.
Specifically, the camera can be installed to the intelligence desk lamp, and it can be in the unactivated state at ordinary times, and when finding illumination angle adjustment instruction not clear, automatic activation is in order to obtain user's image, and this kind of mode can reduce the consumption of intelligence desk lamp to a certain extent.
Of course, in other embodiments, the camera may be activated for a long time, so as to quickly acquire the user image.
S103, identifying the behavior characteristics of the user from the user image.
Specifically, based on the structure of intelligent desk lamp, the restriction of emplacement position, the shooting region of the camera of intelligent desk lamp is limited, considers that the effect of intelligent desk lamp just provides the light source for the user of sitting beside the desk, consequently, this shooting region has contained the position of sitting that can shoot the user after sitting on the chair.
For example: the intelligent desk lamp is placed on the left side of the desk, a user sits in the middle of the desk, and the camera shooting area is the area in the middle of the desk and covered on the area where the user sits.
The behavior features can be identified by using the existing image identification algorithm, and the specific identification process is not limited herein.
S104, controlling the lamp source to execute corresponding illumination angle adjustment operation according to the behavior characteristics of the user.
Specifically, when the user image is obtained, behavior characteristics (such as sitting posture characteristics, standing posture characteristics, no user and the like) on the user image can be identified, and according to the corresponding behavior characteristics, how to control the illumination angle of the light source is determined.
Optionally, the step S104 of controlling the light source to perform the corresponding lighting angle adjustment operation according to the behavior characteristics of the user includes the following steps:
when the behavior characteristic is a sitting posture characteristic, analyzing the adjustment angle of the light source by combining the current illumination angle of the light source and the azimuth information corresponding to the sitting posture characteristic;
adjusting the illumination angle of the lamp source according to the adjustment angle of the lamp source;
when the behavior characteristic is the non-sitting posture characteristic, the illumination angle of the light source is not adjusted.
Specifically, the intelligent desk lamp generally provides a light source for people sitting at a desk or a bedside, so that sitting posture is set in a preset database as a target feature, the recognized behavior feature is matched with the target feature, and when the matching is successful, the behavior feature is the sitting posture feature.
When the sitting posture characteristic is recognized, the user is considered to be sitting beside the desk and needs the light source to be driven beside the desk, and therefore the direction information corresponding to the sitting posture characteristic is the area which needs to be covered by the light source.
The adjustment angle of the lamp source can be successfully calculated through the current illumination angle of the lamp source and the position information corresponding to the sitting posture characteristic, and the lamp source can be conveniently adjusted according to the adjustment angle subsequently.
Optionally, when the illumination angle of the lamp source is adjusted, if the lamp source is not turned on, the lamp source is turned on; if the light source is turned on, only the illumination angle of the light source is adjusted.
Specifically, the illumination angle in adjustment lamp source is mainly in order to provide the light of better angle for the user, when the lamp source of intelligent desk lamp just opened originally, do not need to go to open the lamp source again, as long as adjustment illumination angle can, if the lamp source of intelligent desk lamp does not open, then when the illumination angle in adjustment lamp source, open the lamp source automatically, save the step that the user manually opened the lamp source, user's operation has been simplified, make intelligent desk lamp more intelligent, improve user's use and experience.
In this embodiment, the illumination angle of lamp source can be adjusted by oneself according to the user's image that the camera was shot, also can adjust by oneself through this instruction when receiving clear illumination angle adjustment instruction, need not the position of user's manual removal lamp source, and convenient to use makes intelligent desk lamp more intelligent, and the illumination angle self-adaptability of its lamp source is better.
In another embodiment of the present invention, as shown in fig. 2, a method for adjusting an illumination angle is applied to an intelligent desk lamp, and the method for adjusting an illumination angle includes the following steps:
s201, when the illumination angle adjusting instruction is received, whether the illumination angle adjusting instruction is clear or not is analyzed.
Optionally, when the illumination angle adjustment instruction is received, analyzing whether the illumination angle adjustment instruction is clear includes the following steps:
When the illumination angle adjusting instruction does not contain angle information, the illumination angle adjusting instruction is not clear;
and when the illumination angle adjusting instruction contains angle information, the illumination angle adjusting instruction is clear, and the illumination angle of the lamp source is adjusted according to the angle information.
And S202, if the illumination angle adjusting instruction is not clear, acquiring a user image through the camera.
S203 identifies the behavior feature of the user from the user image.
According to the behavior characteristics of the user, the control light source executes the corresponding illumination angle adjustment operation, and the control light source comprises the following steps:
s204, when the behavior characteristic is a sitting posture characteristic, analyzing an adjustment angle of the light source by combining the current illumination angle of the light source and the azimuth information corresponding to the sitting posture characteristic;
s205, adjusting the illumination angle of the lamp source according to the adjustment angle of the lamp source;
and S206, when the behavior characteristic is the non-sitting posture characteristic, not adjusting the illumination angle of the light source.
Optionally, when the behavior feature is a sitting posture feature, the step S204 of analyzing the adjustment angle of the light source by combining the current illumination angle of the light source and the orientation information corresponding to the sitting posture feature includes the following steps:
s214, when the behavior characteristic is a sitting posture characteristic, identifying the orientation information corresponding to the sitting posture characteristic;
S224, calculating a standard illumination angle of the lamp source covering the azimuth information corresponding to the sitting posture characteristic according to the parameter information of the lamp source;
s234, calculating the adjusting angle of the lamp source according to the standard illumination angle and the current illumination angle of the lamp source.
Specifically, the orientation information corresponding to the sitting posture feature is orientation information corresponding to the position of a hand feature or a learning tool (such as a book, a pen, a tablet computer, and the like) in the user image.
When a user sits, the two hands are generally placed on a table top, and the positions of the two hands are the places where the user wants to light the light sources; of course, sometimes the user may just sit down, and the user's hands are not necessarily placed on the table top, and the position of the learning tool placed on the table top can be used as the orientation information of the sitting posture feature.
Of course, the orientation information corresponding to other features can be set as the orientation information of the sitting posture feature as long as the light source can be better used for lighting the user.
The parameter information of the light source comprises the height of the light source from the desktop and the position of the light source on the desk. The parameter information of the lamp source determines the illumination area which can be covered by the lamp source by rotating different angles, so that after the azimuth information corresponding to the sitting posture characteristic is confirmed, the standard illumination angle of the lamp source when the lamp source covers the position corresponding to the azimuth information is reversely calculated, and then the adjustment angle of the lamp source is calculated by performing difference operation on the current illumination angle of the lamp source and the standard illumination angle according to the current illumination angle of the lamp source.
For example: after the position information corresponding to the sitting posture characteristic is determined, when the standard angle of the lamp source is analyzed to be A, the lamp light can cover the position corresponding to the position information, and the current illumination angle of the lamp source is B, so that the adjustment angle of the lamp source can be calculated by performing difference operation on A and B.
Optionally, in actual application, the rotatable angle range of the light source is set to be 0-N degrees from left to right, positive when rotating from left to right, and negative when rotating from right to left, which is greater than the standard illumination angle of the light source and the current illumination angle of the light source is compared, and the rotation direction of the adjustment angle is determined.
For example: the standard illumination angle of the lamp source is calculated to be 60 degrees, the current illumination angle of the lamp source is 45 degrees, and the comparison shows that the standard illumination angle is larger than the current illumination angle, so that the lamp source needs to rotate by 15 degrees to the right.
For another example: the standard illumination angle of the lamp source is calculated to be 60 degrees, the current illumination angle of the lamp source is 100 degrees, and the comparison shows that the standard illumination angle is smaller than the current illumination angle, so that the lamp source needs to rotate by 40 degrees leftwards.
Of course, the method is not limited to the embodiment for determining the rotation direction of the adjustment angle, and other methods in the prior art may be used as long as the rotation direction of the adjustment angle can be indicated, and the method is not limited herein.
Optionally, when the illumination angle of the lamp source is adjusted, if the lamp source is not turned on, the lamp source is turned on; if the light source is turned on, only the illumination angle of the light source is adjusted.
In this embodiment, intelligence desk lamp can be according to the position information that the position of sitting in a sitting posture characteristic in the user's image corresponds, and the illumination angle with the lamp source is turned to the position that covers this position information and corresponds automatically, need not the position of user's manual removal lamp source in the adjustment process of the illumination angle of whole lamp source, is accomplished by intelligent desk lamp is automatic, has simplified user's operation, makes intelligent desk lamp more intelligent, has improved user's use greatly and has experienced.
