In some embodiments, when the controller 205 controls the following detection component 20 to follow the user, then the following detection component 20 adjusts the angle and the adjustment direction to the target detection position, and generates a real-time pose image at the target detection position. Further, the controller 205 controls the illumination assembly 14 to rotate according to the adjustment direction and the angle according to the angle adjusted to the target detection position by the following detection assembly 20 and the adjustment direction.

For example, the infrared thermal imaging sensor senses the temperature of infrared rays (hot wires) emitted by a user through a temperature difference detection principle, and outputs the outline of an image according to the temperature difference, and the controller 205 can recognize whether a person exists or not by acquiring a multi-dot matrix image (e.g., 8 × 8 dot matrix image) output by the infrared thermal imaging sensor and recognize a posture of a human body, and can also determine the change of the posture according to the posture of the human body acquired at the previous time and the next time.

Specifically, when the controller 205 recognizes that the posture of the human body is facing left, or the posture of the human body changes facing left, the controller 205 controls the rotating motor and the driving motor to rotate left, so as to drive the detecting component and the light emitting component to rotate left relative to the base; when the controller 205 recognizes that the posture of the human body is facing to the right, or the posture of the human body changes to the right, the controller 205 controls the rotating motor and the driving motor to rotate to the right, so as to drive the detecting part and the light emitting part to rotate to the right relative to the base.

The controller 205 controls the motors to rotate according to the posture of the human body, so that the detection part can face the direction of the human body, the error of sitting posture detection caused by position change of the desk lamp or seat change is avoided, further, the angle of the light-emitting part can be adjusted, the reading and writing area is located in the optimal illumination area, the learning environment is improved, and the influence of uneven illumination on eyesight is reduced.

Referring to fig. 3, the desk lamp 100 further includes a first motor driving circuit 301 and a second motor driving circuit 302, an input end of the first motor driving circuit 301 is connected to the controller 205, an output end of the first motor driving circuit 301 is connected to the rotating motor 231, an input end of the second motor driving circuit 302 is connected to the controller 205, and an output end of the second motor driving circuit 302 is connected to the driving motor 303.

The controller 205 drives the rotation motor 231 to rotate through the first motor driving circuit 301, and further drives the detection component to rotate along with the user. The controller 205 drives the driving motor 303 to rotate through the second motor driving circuit 302, so as to drive the light emitting component to rotate.

In some embodiments, a position encoder 304 is disposed on the rotating motor 231, the position encoder 304 is electrically connected to the controller 205, and the controller 205 obtains the rotation angle of the rotating motor 231 through the position encoder 304. When the rotating motor 231 rotates, the position encoder 304 rotates by a corresponding angle along with the concentric shaft, and the rotating angle of the rotating motor 231 is obtained according to the absolute position of the position encoder 304.

In some embodiments, the rotation motor 231 and the driving motor 303 may be any suitable type of motor, such as a stepper motor, or the like.

The first controller 2051 is also equivalent to a main controller, the second controller 2052 is also equivalent to a slave controller, and the two controllers are arranged in the desk lamp because the rotating motor 231 and the driving motor 303 are arranged at different positions, so that the two controllers can be arranged on different circuit boards, and the wiring in the desk lamp is simple. The first controller 2051 and the second controller 2052 are processors with certain logical operation capability, and may be a single chip microcomputer (e.g., STM32), a microprocessor, or the like of a suitable type.

The first controller 2051 includes a storage block 307, and the storage block 307 stores therein the correspondence between the rotation angle of the rotation motor 231 and the rotation angle of the drive motor 303. In practical application, in order to make the following detection component face the direction of the human body so as to accurately monitor the posture of the human body in front of the desk, the deflection angle of the posture of the human body relative to the center of the multi-point array image is consistent with the rotation angle of the rotating motor 231, and the rotation angle of the driving motor 303 of the rotation angle of the rotating motor 231 can be the same or different.

It can be understood that the illumination area of the light emitting part is a larger range, and the direction of the light emitting part may not be adjusted in the case that the deflection angle of the human body posture is small or the rotation angle of the rotation motor 231 is small; in the case where the deflection angle of the human body posture is large or the rotation angle of the rotation motor 231 is large, the direction of the light emitting part is adjusted by the driving motor 303.

For example, the corresponding relationship between the rotation angle of the rotation motor 231 and the rotation angle of the driving motor 303 is a piecewise function, and when the rotation angle α of the rotation motor 231 is smaller than a preset value, the rotation angle β of the driving motor 303 is 0; when the rotation angle α of the rotation motor 231 is equal to or greater than the preset value, the rotation angle β of the drive motor 303 becomes K α (0< K < 1).

In the above embodiment, the ultrasonic sensor 306 is electrically connected to the first controller 2051, the ultrasonic sensor 306 is configured to detect a distance between the user and the desk lamp, and the first controller 2051 is further configured to control the infrared thermal imaging sensor 305 to perform human posture detection when the distance is smaller than a preset distance threshold, so as to reduce power consumption of the desk lamp.

As shown in fig. 5a, the method S500 includes:

s510, acquiring a real-time attitude image of a user;

in the present embodiment, the user includes a living body having a physiological activity, such as a natural human, an animal, or the like. When the desk lamp works, a user sits towards the desk lamp, and then the following detection component in the desk lamp can generate each posture image of the user in different postures. According to the acquisition cycle, the following detection assembly can obtain the attitude image corresponding to each current moment, for example, the following detection assembly can generate the real-time attitude image according to a preset time interval, and for example, if the preset time interval is t, the following detection assembly respectively generates the real-time attitude image at 0, t, 2t, 3t … … and the like. In the present embodiment, the attitude image corresponding to each current time is made to be a real-time attitude image.

In some embodiments, optionally, each pose image generated by the following detection component at different poses is a uniform format dot matrix image, such as an 8 x 8 dot matrix representation or a 64 x 64 dot matrix representation, and so on.

S520, determining the current posture of the user according to the real-time posture image;

in this embodiment, the desk lamp analyzes the real-time posture image through an image analysis algorithm to obtain a real-time posture contour of the user, and the real-time posture contour is used as the current posture of the user.

And S530, controlling the following detection assembly to follow the user according to the current posture of the user so as to generate a target posture image, wherein the portrait of the user is presented at the preset image position of the target posture image.

In this embodiment, after the sitting posture of the user deviates from the original position, the desk lamp controls the following detection component to follow the user, and the desk lamp further analyzes each frame of real-time posture image generated in the process that the following detection component follows the user, and if it is detected again that the portrait of the user is presented at the preset image position of the real-time posture image at the specific moment, the desk lamp stops driving the following detection component to rotate at the specific moment.

In the present embodiment, the "preset image position" is a portrait position of the user in the attitude image set in advance. In this embodiment, after the real-time pose image of the user is acquired, it may be determined whether the portrait of the user in the real-time pose image is located at a preset image position in the real-time pose image through image processing. For example, assuming that the preset image position is the center of the gesture image, after the real-time gesture image of the user is acquired, the portrait position of the user in the real-time gesture image is determined, if the portrait position of the user is the center of the real-time gesture image, the portrait of the user is located in the preset image position in the real-time gesture image, and if the portrait position of the user is not the center of the real-time gesture image, the portrait of the user is not located in the preset image position in the real-time gesture image.

Referring to fig. 5b, when the pose image is a dot matrix image, the predetermined image position is a central region of the dot matrix image.

In this embodiment, after the target posture image is detected by the desk lamp, the following detection component is adjusted to the target detection position. The "target detection position" is a position at which the portrait of the user can be presented at a preset image position of the target posture image. The preset image position may be a central position of the target posture image.

In this embodiment, the specific implementation may be: if the posture change of the user is detected, controlling the following detection assembly to move to a first detection position and acquiring a posture image of the user, if the posture image acquired at the first detection position is the same as the posture image before the posture change, enabling the following detection assembly to be located at a target detection position, and taking the posture image acquired at the first detection position as a target posture image; if the position of the attitude image acquired at the first detection position is different from the position of the attitude image before the attitude change, controlling the following detection component to move to a second detection position and acquire the attitude image of the user, if the position of the attitude image acquired at the second detection position is the same as the position of the attitude image before the attitude change, the following detection component is already at the target detection position, taking the attitude image acquired at the second detection position as the target attitude image, and if the position of the attitude image acquired at the second detection position is different from the position of the attitude image before the attitude change, continuously adjusting the position of the following detection component until the position of the acquired attitude image is the same as the position of the attitude image before the attitude change. For example, if it is determined that the posture of the user changes to move leftward based on the posture image a at the previous time and the posture image B at the current time, the following detection component is controlled to rotate leftward to acquire a posture image C of the user, and if the position of the user in the posture image a is the same as that in the posture image C, the following detection component is already at the target detection position, and the posture image C is taken as the target posture image.

Optionally, in some other embodiments, the target posture image may be generated by the following detection component by adjusting the motion amplitude of the following detection component according to the amplitude of the posture change of the user to move the following detection component to the target detection position. For example, if it is determined that the posture of the user changes to move leftward and the change distance is X, and the change angle of the follow-up detection component is converted to X × M, from the posture image a at the previous time and the posture image B at the current time, the follow-up detection component is controlled to rotate X × M leftward and the posture image C of the user is acquired, and if the position of the user in the posture image a is the same as that in the posture image C, the follow-up detection component is already at the target detection position, and the posture image C is taken as the target posture image.

If the gesture of the user changes towards the first direction, determining that the change type of the current gesture of the user is a first gesture change type; and if the gesture of the user changes towards the second direction, determining that the change type of the current gesture of the user is a second gesture change type. For example, assuming that the first direction is the left direction and the second direction is the right direction, in the real-time posture image A, B, if the posture of the user moves to the left, the change type of the current posture of the user is determined to be the first posture change type, and if the posture of the user moves to the right, the change type of the current posture of the user is determined to be the second posture change type.

And if the change type of the current posture of the user is the second posture change type, controlling the following detection assembly to follow the user according to the second direction so as to generate a target posture image. For example, assuming that the first direction is the left direction and the second direction is the right direction, if the posture of the user moves to the left direction, the following detection component is adjusted to the target detection position to generate the target posture image to the left direction, and if the posture of the user moves to the right direction, the following detection component is adjusted to the target detection position to generate the target posture image to the right direction.
