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 flow chart of an implementation of a method for adjusting an illumination angle according to the present invention, which can be applied to an intelligent desk lamp, and the method for adjusting an illumination angle includes the following steps:
s101, when receiving an illumination angle adjusting instruction, acquiring a user image through a camera.
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 lighting angle adjusting instruction is sent by a mobile phone, or sent by a related sending area with the lighting angle adjusting instruction on the intelligent desk lamp (for example, related buttons are pressed several times, and the intelligent desk lamp receives the lighting angle adjusting instruction by default).
The lighting angle adjusting instruction comprises an instruction angle, so that the intelligent desk lamp can directly adjust the lamp source according to the instruction angle.
For example: the user says that the lamp source rotates 30 degrees to the left for the intelligent desk lamp, which is a lighting angle adjusting instruction, and the intelligent desk lamp can execute the rotation operation according to the clear instruction.
For another example: the user presses a feature key (the size of the command angle is adjusted through an up key and a down key, one step value corresponds to one step, for example, 5 degrees, and the number of times of pressing the feature key is the input of the illumination angle adjustment command) on the intelligent desk lamp, and the intelligent desk lamp considers that the illumination angle adjustment command input by the user is received.
For another example: the mobile phone (terminal equipment such as a tablet computer) of the user is in communication connection with the intelligent desk lamp, the user inputs 'the lamp source is adjusted by 15 degrees leftwards' on the mobile phone and then the lamp source is sent to the intelligent desk lamp, and the intelligent desk lamp considers that the intelligent desk lamp receives an illumination angle adjusting instruction input by the user.
After receiving the illumination angle adjusting instruction (input by the user), the intelligent desk lamp cannot be executed immediately according to the illumination angle adjusting instruction, but acquires the user image through the camera to confirm the current direction information of the user, and further ensures that the lamp source can more accurately irradiate the actual position desired by the user.
In order to obtain the user image, the camera can be installed on the intelligent desk lamp, the intelligent desk lamp can be in an inactivated state at ordinary times, when the illumination angle adjusting instruction is received, the camera is automatically activated to obtain the user image, and the power consumption of the intelligent desk lamp can be reduced to a certain extent by the aid of the method.
Of course, in other embodiments, the camera may be activated for a long time, so as to quickly acquire the user image.
S102, the sitting posture feature of the user is recognized 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 sitting posture characteristic can be recognized by adopting the existing image recognition algorithm, the specific recognition process is not limited, and the prior art can be referred.
S103, analyzing the adjusting 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.
Specifically, when the sitting posture characteristic is recognized, the user is considered to be sitting beside the desk and needs to drive the light source to the side, 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 subsequently.
Optionally, in S103, by combining the current illumination angle of the light source and the orientation information corresponding to the sitting posture characteristic, analyzing the adjustment angle of the light source includes:
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;
and 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 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 illumination angle needing the lamp source is analyzed to be A, the lamp light can cover the position corresponding to the position information, the current illumination angle of the lamp source is B, and therefore the adjustment angle of the lamp source can be calculated through the difference operation of 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, 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 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 of determining the rotation direction of the adjustment angle is not limited to the embodiment, 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.
And S104, when the illumination angle adjusting instruction does not accord with the adjusting angle, sending out prompt information, wherein the prompt information is used for prompting a user whether to continuously adjust the illumination angle of the lamp source according to the illumination angle adjusting instruction.
Specifically, when a user sends a lighting angle adjusting instruction, the instruction angle is input according to the feeling of the user in most cases, the accuracy is not high, and the adjusting angle is calculated according to the sitting posture characteristics of the user by the intelligent desk lamp, so that the actual requirements of the user are met approximately.
Therefore, when the two do not match, the reason for issuing the prompt message is that: firstly, reminding a user that the actual effect is possibly not good if the lamp source is adjusted according to the instruction angle in the illumination angle adjusting instruction sent just now; secondly, the user is given the opportunity to choose, and there are other reasons why he may leave the light source out of the position corresponding to his sitting posture feature, for example: the user wants to carefully observe the product under weak light, so the light source needs to be removed and the area corresponding to the sitting posture feature of the user does not need to be illuminated.
The sending of the prompt message can take the above reasons into consideration, so that the user can know that the instruction angle is not appropriate, and the user can have more choices, and the actual requirements of the user are considered in many ways.
And S105, after receiving a confirmation instruction sent by the user according to the prompt message, adjusting the illumination angle of the lamp source according to the illumination angle adjusting instruction.
Specifically, the confirmation instruction is that the user confirms that the light source is adjusted according to the illumination angle adjustment instruction, and the specific form is not limited.
For example: the content of the prompt message is that the lighting angle adjusting instruction is not in line with the actual situation, and cannot be used in places where people work and learn after sitting down, and ask whether to adjust the light source according to the adjusting angle, if the user answers no, the intelligent desk lamp considers that the confirmation instruction is received, and then the lighting angle of the light source is adjusted according to the lighting angle adjusting instruction is confirmed.
Optionally, the method for adjusting the illumination angle further includes: and after a rejection instruction sent by the user according to the prompt message is received, adjusting the illumination angle of the lamp source according to the adjustment angle.
Similarly, the rejection instruction means that the user confirms to adjust the light source according to the adjustment angle, and the specific form is not limited.
For example: for example: the content of the prompt message is that the lighting angle adjusting instruction is not in line with the actual situation, and can not be used in places where people work and study after sitting down, and ask whether the light source needs to be adjusted according to the bright angle adjusting instruction, if the user answers no, the intelligent desk lamp considers that the rejection instruction is received, and then the intelligent desk lamp confirms that the light source is adjusted according to the adjusting angle.
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.
The utility model discloses a lamp source, the illumination angle who adjusts the lamp source is mainly in order to provide the light of better angle for the user, when the lamp source of intelligence desk lamp just opened originally, it is unnecessary to go to open the lamp source again, as long as adjustment illumination angle can, if the lamp source of intelligence desk lamp does not open, then when the illumination angle of 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 intelligence desk lamp more intelligent, improve user's use and experience.
In this embodiment, the illumination angle of lamp source can combine position of sitting characteristic and illumination angle adjustment instruction to carry out the comprehensive consideration when adjusting, need not user's manual participation, ensures that the illumination angle after the regulation can accord with user's actual demand, improves its and uses experience.

S204, calculating the adjusting angle of the lamp source according to the standard lighting angle and the current lighting angle of the lamp source.
When the illumination angle adjusting instruction is not in accordance with the adjusting angle, the step of sending out prompt information comprises the following steps:
s205, when the error value between the command angle and the adjusting angle in the lighting angle adjusting command is larger than the preset error value, the lighting angle adjusting command and the adjusting angle are considered not to be matched, and prompt information is sent, wherein the prompt information is used for prompting a user whether to continuously adjust the lighting angle of the lamp source according to the lighting angle adjusting command.

And carrying out error operation on the calculated adjusting angle and the instruction angle in the illumination angle adjusting instruction, and if the error value of the calculated adjusting angle and the instruction angle in the illumination angle adjusting instruction is greater than a preset error value, indicating that the illumination angle adjusting instruction is not in line with the actual sitting posture condition of the user, so that the user can further confirm the adjustment by considering that the illumination angle adjusting instruction and the adjusting angle are not in line with each other and sending prompt information to ensure that the actual requirement of the user can be met after the illumination angle of the lamp source is adjusted.
Optionally, the method for adjusting the illumination angle further comprises the following steps:
s207, when the illumination angle adjusting instruction and the adjusting angle are in accordance (namely the error value between the instruction angle and the adjusting angle in the illumination angle adjusting instruction is not larger than a preset error value), calculating the average angle of the instruction angle and the adjusting angle in the illumination angle adjusting instruction;
s208, adjusting the illumination angle of the lamp source according to the average angle.
Specifically, when the error value of the lighting angle adjustment instruction and the adjustment angle is not greater than the preset error value, it is indicated that the orientation information corresponding to the sitting posture characteristic of the user is the place that the user wants the lamp source to illuminate, but the user may have some special requirements to reach the lighting angle adjustment instruction, so that the lighting angle of the lamp source is adjusted by comprehensively considering the instruction angle and the adjustment angle, and the adjustment of the lamp source is more accurate.
For example: the instruction angle is 15 degrees left, and the angle of adjustment is 13 degrees left, and the average angle of both is 14 degrees left, and intelligent desk lamp just adjusts the illumination angle of lamp source according to 14 degrees left.
In the embodiment, according to the condition of the error value between the instruction angle and the adjustment angle, different modes are selected to automatically adjust the illumination angle of the lamp source, so that the adjusted lamp source can meet the actual requirements of users, manual participation of the users is not needed, the intelligent desk lamp is more intelligent, and the use experience of the users is greatly improved.
