In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following description will explain the specific embodiments of the present invention with reference to the accompanying drawings. It is evident that the drawings in the following description are only examples of the invention, from which other drawings and other embodiments can be obtained by a person skilled in the art 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 intelligent desk lamp is annular, and the link on the lamp source is connected on a rotation axis that can upper and lower, left and right regulation, 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 an illumination angle adjustment method of the present invention, which can be applied to an intelligent desk lamp, and the illumination angle adjustment method includes the following steps:
s101, when an illumination angle adjusting instruction is received, a user image is acquired through a camera.
Specifically, the user may send the illumination angle adjustment instruction through voice, or may use other manners, for example: the intelligent desk lamp sends the illumination angle adjusting instruction through a mobile phone or sends the illumination angle adjusting instruction through a relevant sending area (for example, a relevant button is pressed down, and the intelligent desk lamp receives the illumination angle adjusting instruction by default).
The illumination angle adjusting instruction is an instruction containing 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 "the lamp source rotates 30 degrees to the left" to intelligent desk lamp, this is an illumination angle adjustment instruction, intelligent desk lamp can be according to the rotatory operation of clear instruction execution.
For another example: the user presses a characteristic key (the size of the instruction angle is adjusted by an up key and a down key, one stepping value corresponds to one stepping value at a time, for example, 5 degrees, the number of times of pressing the characteristic key is the input of the illumination angle adjustment instruction), and the intelligent desk lamp considers that the illumination angle adjustment instruction input by the user is received.
And, for 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 'adjust the lamp source to the left by 15 degrees' on the mobile phone and sends the lamp source to the intelligent desk lamp, and the intelligent desk lamp considers that the intelligent desk lamp receives the illumination angle adjusting instruction input by the user.
After receiving the illumination angle adjusting instruction (input by a user), the intelligent desk lamp does not immediately execute according to the illumination angle adjusting instruction, but acquires the user image through the camera to confirm the current azimuth information of the user, so that the lamp source can be further ensured to irradiate the actual position wanted by the user more accurately.
In order to acquire the user image, the intelligent desk lamp is provided with a camera which can be in an inactive state at ordinary times, and when an illumination angle adjusting instruction is received, the camera is automatically activated to acquire the user image, so that the power consumption of the intelligent desk lamp can be reduced to a certain extent.
Of course, in other embodiments, the camera may be activated for a long period of time to facilitate rapid acquisition of the user image.
S102, identifying sitting posture characteristics of the user from the user image.
Specifically, based on the restriction of the structure and the placement position of the intelligent desk lamp, the shooting area of the camera of the intelligent desk lamp is limited, and the effect of the intelligent desk lamp is considered to provide a light source for a user sitting beside the desk, so that the shooting area comprises a sitting posture after the user sits on a 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 in the middle of the desk and covers the area where the user sits.
The identification of the sitting posture features can be achieved by using an existing image identification algorithm, and the specific identification process is not limited herein, and reference can be made to the prior art.
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 characteristics.
Specifically, when the sitting gesture is identified, the user is considered to sit beside the table, and the light source needs to be driven to the side of the table, so that the azimuth information corresponding to the sitting gesture is the area to be covered by the light source.
The adjusting angle of the lamp source can be successfully calculated through the current illumination angle of the lamp source and the azimuth information corresponding to the sitting posture characteristics, so that the lamp source can be conveniently adjusted subsequently.
Optionally, S103, in combination with the current illumination angle of the light source and the azimuth information corresponding to the sitting gesture feature, analyzing the adjustment angle of the light source includes:
according to the parameter information of the lamp source, calculating a standard illumination angle of the lamp source covering the azimuth information corresponding to the sitting posture characteristics;
and calculating the adjusting angle of the light source according to the standard illumination angle and the current illumination angle of the light source.
Specifically, the azimuth information corresponding to the sitting posture feature is azimuth information corresponding to the hand feature or the position of a learning tool (for example, a book, a pen, a tablet computer, etc.) in the user image.
When a user sits, two hands are generally placed on the desktop, and the positions of the two hands are the places where the user wants the light source to shine; of course, sometimes the user may just sit down, his or her hands are not necessarily placed on the table, and the position of the learning tool placed on the table may be used as the orientation information of the sitting posture feature.
Of course, the azimuth information corresponding to other features can be set as the azimuth information of the sitting posture feature, so long as the lamp source can better shine for the user.
The parameter information of the light source comprises the height of the light source from the table top and the position of the light source on the table. The parameter information of the lamp source determines the illumination areas which can be covered by different rotation angles, so that after the azimuth information corresponding to the sitting posture characteristics 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 according to the current illumination angle of the lamp source and the difference operation of the current illumination angle of the lamp source.
For example: after the azimuth information corresponding to the sitting posture characteristics is determined, when the standard illumination angle of the lamp source is analyzed to be A, the lamp light can cover the position corresponding to the azimuth information, and the current illumination angle of the lamp source is B, so that the adjustment angle of the lamp source can be calculated through difference operation between A and B.
Optionally, in practical application, the rotatable angle range of the lamp source is set to be 0-N degrees from left to right, positive when the lamp source rotates from left to right, negative when the lamp source rotates from right to left, and the standard illumination angle of the lamp source and the current illumination angle of the lamp source are compared to be larger, so that the rotation direction of the adjustment angle is confirmed.
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 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 comparison shows that the standard illumination angle is smaller than the current illumination angle, so that the lamp source needs to be rotated leftwards by 40 degrees.
Of course, the rotation direction of the adjustment angle is not limited to the embodiment, and other methods in the prior art are not limited thereto as long as the rotation direction of the adjustment angle can be indicated.
And S104, when the illumination angle adjusting instruction and the adjusting angle are not matched, a prompt message is sent, wherein the prompt message is used for prompting a user whether to continuously adjust the illumination angle of the light source according to the illumination angle adjusting instruction.
Specifically, when a user sends an illumination angle adjusting instruction, the instruction angle is input according to the sense of the user in most cases, the accuracy is not high, the adjusting angle is calculated by the intelligent desk lamp according to the sitting posture characteristics of the user, and the high probability meets the actual demands of the user.
Therefore, when the two do not coincide, the reason for sending the prompt information is that: firstly, the user is reminded that if the lamp source is regulated according to the instruction angle in the illumination angle regulation instruction sent just before, the actual effect may not be good; secondly, the user is given a choice opportunity, and there are other reasons why the light source may not be in the position corresponding to the sitting posture feature, for example: the user wants to carefully observe the product under the weak light, so that the light source needs to be removed, and the user does not need to take the area corresponding to the sitting posture characteristics of the user.
The sending of the prompt information can take the reasons as well, so that the user can know that the instruction angle is not proper, the user can have more selection opportunities, and the actual demands of the user are considered in many aspects.
S105, after receiving a confirmation instruction sent by a user according to the prompt information, adjusting the illumination angle of the lamp source according to the illumination angle adjusting instruction.
Specifically, the confirmation instruction refers to that the user confirms that the lamp source is regulated according to the illumination angle regulation instruction, and the specific form is not limited.
For example: the content of the prompt information is that the illumination angle adjusting instruction is not in line with the actual situation, the user cannot shine to the place where he sits down and works and learns, ask whether to adjust the lamp source according to the adjusting angle, if the user answers no, the intelligent desk lamp considers that the illumination angle adjusting instruction is received, namely, the intelligent desk lamp confirms that the illumination angle of the lamp source is adjusted according to the illumination angle adjusting instruction.
Optionally, the method for adjusting the illumination angle further includes: and after receiving a rejection instruction sent by a user according to the prompt information, adjusting the illumination angle of the lamp source according to the adjustment angle.
Similarly, the rejection instruction refers to that the user confirms that the lamp source is adjusted according to the adjustment angle, and the specific form is not limited.
For example: for example: the content of the prompt information is that the illumination angle adjusting instruction is not in line with the actual situation, the user cannot shine to the place where the user sits down and works and learns, ask whether the adjustment of the light source is still required according to the illumination angle adjusting instruction, the user answers no, and the intelligent desk lamp considers that the intelligent desk lamp receives the rejection instruction, namely confirms that the adjustment of the light source is carried out according to the adjusting angle.
Optionally, when adjusting the illumination angle of the light source, if the light source is not turned on, turning on the light source; if the light source is turned on, only the illumination angle of the light source is adjusted.
Specifically, adjust the illumination angle of lamp source mainly in order to provide better angle's light for the user, when the lamp source of intelligent desk lamp originally was opened, need not go to open the lamp source again, as long as adjust illumination angle can, if the lamp source of intelligent desk lamp does not open, then when the illumination angle of adjustment lamp source, automatic start lamp source, save the step that the manual start lamp source of user, simplified user's operation, make intelligent desk lamp more intelligent, improve user's use experience.
In this embodiment, when adjusting, the illumination angle of lamp source can combine position of sitting characteristic and illumination angle adjustment instruction to carry out comprehensive consideration, need not the manual participation of user, ensures that the illumination angle after adjusting can accord with user's actual demand, improves its use experience.
Based on the improvement of the above embodiment, 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 includes the following steps:
s201, when an illumination angle adjusting instruction is received, a user image is acquired through a camera.
S202 identifies the sitting posture feature of the user from the user image.
Combining the current illumination angle of the lamp source and the azimuth information corresponding to the sitting posture characteristics, analyzing the adjustment angle of the lamp source comprises the following steps:
s203, calculating a standard illumination angle of the lamp source covering the azimuth information corresponding to the sitting posture characteristics according to the parameter information of the lamp source (the parameter information of the lamp source comprises the height of the lamp source from the desktop and the position of the lamp source on the desk); optionally, the orientation information corresponding to the sitting posture feature is orientation information corresponding to the hand feature or the position of a learning tool (e.g., book, pen, tablet computer, etc.) in the user image.
S204, calculating the adjustment angle of the light source according to the standard illumination angle and the current illumination angle of the light source.
When the illumination angle adjusting instruction and the adjusting angle are not matched, sending prompt information comprises the following steps:
and S205, when the error value between the instruction angle and the adjusting angle in the illumination angle adjusting instruction is larger than a preset error value, the illumination angle adjusting instruction and the adjusting angle are not met, and prompt information is sent out, 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.
S206, after receiving a confirmation instruction sent by the user according to the prompt information, adjusting the illumination angle of the lamp source according to the illumination angle adjusting instruction.
Specifically, the preset error value is set according to the accuracy requirement, for example: may be set to 20 degrees, 5 degrees, 10 degrees, 8 degrees, or the like.
And carrying out error operation on the calculated adjusting angle and the instruction angle in the illumination angle adjusting instruction, if the error value of the calculated adjusting angle and the instruction angle in the illumination angle adjusting instruction is larger than a preset error value, the illumination angle adjusting instruction is not in accordance with the actual sitting posture condition of the user, so that the illumination angle adjusting instruction and the adjustment angle are considered to be not in accordance, prompt information is required to be sent out, the user can further confirm, and the actual requirement of the user can be met after the illumination angle of the light source is adjusted.
Optionally, the method for adjusting the illumination angle further comprises the following steps:
s207, when the illumination angle adjustment instruction and the adjustment angle are in accordance (namely, the error value between the instruction angle and the adjustment angle in the illumination angle adjustment instruction is not more than a preset error value), calculating the average angle of the instruction angle and the adjustment angle in the illumination angle adjustment instruction;
s208, adjusting the illumination angle of the lamp source according to the average angle.
Specifically, when the error value of the illumination angle adjustment command and the adjustment angle is not greater than the preset error value, the azimuth information corresponding to the sitting gesture feature of the user is indicated to be the place where the user wants the light source to illuminate, but the illumination angle adjustment command is given by considering that the user possibly has some special demands, so that the illumination angle of the light source is adjusted by comprehensively considering the command angle and the adjustment angle, and the adjustment of the light source is more accurate.
For example: the instruction angle is 15 degrees to the left, the adjustment angle is 13 degrees to the left, the average angle of the instruction angle and the adjustment angle is 14 degrees to the left, and the intelligent desk lamp adjusts the illumination angle of the lamp source according to the 14 degrees to the left.
In this embodiment, according to the condition of error value between instruction angle and the angle of regulation, select different modes to carry out automatically regulated to the illumination angle of lamp source, make the lamp source after adjusting more satisfy user's actual demand, and need not the manual participation of user, make intelligent desk lamp more intelligent, improved user's use experience greatly.
It should be understood that, in the foregoing embodiment, the size of the sequence number of each step does not mean that the execution sequence of each step should be determined by the function and the internal logic, and should not limit the implementation process of the embodiment of the present invention in any way.
