In some embodiments, the scene image is an image including the user acquired by the image acquisition unit 140 when the user uses the desk lamp, or an image excluding the user acquired by the image acquisition unit 140 when the user leaves the desk lamp in a short time when using the desk lamp.

The image acquisition unit 140 may continuously acquire a plurality of scene images, and the duration may be a preset time period. In some embodiments, the image acquisition unit 140 may send all the multiple scene images acquired within the preset duration to the processing unit, may screen the multiple scene images acquired, send the multiple scene images with better definition and better quality to the processing unit, and may acquire the multiple scene images from the acquired scene images with the preset frame number as the frequency and send the multiple scene images to the processing unit.

In some embodiments, the operating state of the light emitting member 130 may include: the system comprises a first working state, a second working state and a third working state, wherein the first working state, the second working state and the third working state are used for reminding a user of working. When the user turns on the desk lamp, the light emitting member 130 is changed from the second operation state to the third operation state. The user turns on the AI intelligent reminding function of the desk lamp, the image acquisition unit 140 of the desk lamp starts to acquire scene images, and when the processing unit determines that the user state is abnormal based on the scene images, the processing unit controls the light emitting part 130 to change from the third working state to the first working state so as to prompt the user that the current state is abnormal; when the processing unit determines that the user has left the desk lamp based on the scene image, the processing unit controls the light emitting element 130 to change from the first operating state or the third operating state to the second operating state.

Wherein the seventh through hole, the eighth through hole and the ninth through hole have the same diameter. The fifth rotating member 123 is disposed in a space between the fourth fixing member 1112 and the fifth fixing member 1113, and the third rotating shaft 1111 is disposed through the seventh through hole, the eighth through hole, and the ninth through hole. Wherein the connection member 120 is capable of rotating with respect to the base 110 about the third rotation axis 1111. For example, when the connection member 120 receives an external force, the connection member 120 can rotate about the third rotation axis 1111 with respect to the base 110.

In some embodiments, the base 110 includes a lamp socket 112 and a lamp post 113 vertically disposed on the lamp socket 112; one end of the lamp post 113 is fixedly connected with the lamp holder 112, and the other end is provided with a fifth rotating member.

In some embodiments, the fifth rotating member 123 may be disposed on the lamp socket 112, and accordingly, the sixth rotating member 111 may be disposed at the bottom of the connecting member 120. Thus, the effect that the connecting piece rotates around the third rotating shaft relative to the base can be achieved.

In some embodiments, the processing unit in the desk lamp comprises an identification unit and a control unit, the control unit being connected with the identification unit; wherein, the liquid crystal display device comprises a liquid crystal display device,

the identification unit is used for detecting each scene image in the plurality of scene images to obtain a key point detection result of each scene image; and the key point detection result is used for representing whether a target object exists in the scene image.

The identification unit is used for generating a control instruction based on a key point detection result of each scene image and sending the control instruction to the control unit;

the control unit is used for controlling the working state of the luminous element based on the control instruction.

Here, the target object refers to a user who uses a desk lamp. When a user starts an AI intelligent reminding function of the desk lamp, the identification unit can receive a plurality of scene images acquired by the image acquisition unit, and then the identification unit can detect each scene image in the plurality of scene images to obtain a key point detection result of each scene image.

The recognition unit may sequentially or simultaneously input the received plurality of scene images into the locally deployed AI module, and determine whether the keypoint information of the target object exists in each scene image. And when the key point detection result of any scene image carries the key point information of the target object, indicating that the target object exists in the scene image. In some embodiments, the keypoint information of the target object may include at least one of: head keypoint information and body keypoint information.

After the recognition unit obtains the key point detection result of each of the scene images, a control instruction may be generated based on the key point detection result of each of the plurality of scene images. The control instruction corresponds to a key point detection result of each scene image. For example, when the keypoint detection result of each scene image does not carry the keypoint information of the target object, it is indicated that no target user exists in the plurality of scene images acquired by the image acquisition unit, that is, it is indicated that the user is not within the range of image acquisition by the image acquisition unit. At this time, the identification unit may generate a control instruction to change the operating state of the light emitting element into the second operating state; when the key point detection result of any scene image carries the key point information of the target object, the user is in the image acquisition range of the image acquisition unit, then the identification unit can determine the user state of the target object in the scene image according to the key point information corresponding to each scene image, and then a control instruction corresponding to the user state of the target object is generated based on the determined user state of the target object.

After the recognition unit generates a control instruction based on the key point detection result of each scene image, the recognition unit sends the control instruction to the control unit, and the control unit can control the working state of the luminous element according to the control instruction.

In some embodiments, the keypoint detection result of the scene image carries keypoint information of the target object; the identification unit is further used for determining the user state of the target object in the scene image based on the key point information corresponding to each scene image; and generating a control instruction corresponding to the user state of the target object.

Here, the user state of the target object is used to indicate whether the physical state of the target object at the current time is an abnormal state and/or to indicate whether the mental state of the target object at the current time is an abnormal state. The body state can be a sitting state of the target object, and when the sitting state of the target object is determined to be a nonstandard state and lasts for a certain time based on key point information of the target object, the body state of the target object at the current moment is determined to be an abnormal state; when the sitting posture state of the target object is determined to be the standard state based on the key point information of the target object, determining that the body state of the target object at the current moment is the normal state; the mental state may represent the fatigue of the target subject at the current moment. The fatigue of the target object at the current moment can be determined in a direct manner or in an indirect manner. For example: the recognition unit may directly determine the fatigue condition of the target object at the current moment based on the facial key point information of the target object corresponding to each of the scene images. The recognition unit can also determine the existence time of the target object based on the key point information of the target object in each scene image, and indirectly determine the fatigue condition of the target object at the current moment based on the existence time.

In some embodiments, the keypoint information carried in the keypoint detection result of the scene image includes head keypoint information and body keypoint information; the recognition unit is further configured to determine, for each of the scene images, a sitting posture state of the target object based on the head key point information and the body key point information of the target object in the scene image; and determining the user state of the target object based on the sitting posture state of the target object in each scene image.

Here, the sitting posture state of the target object includes a standard state and an nonstandard state, the nonstandard state including a first nonstandard state in which the target object has a low head and/or a askew head, and a second nonstandard state in which the target object has a body tilted forward and/or sideways.

The body key point information comprises left shoulder key point information and right shoulder key point information, the head key point information comprises face key information, and the face key information comprises nose tip key point information and chin key point information; when the included angles of the first connecting line and the second connecting line of the nose tip key point information and the chin key point information are determined to be in a first preset range, determining the sitting posture state of the target object to be a first nonstandard state, wherein the second connecting line is a line segment which is perpendicular to the connecting line between the left shoulder key point information and the right shoulder key point information on a first preset plane, and the first preset plane is a plane parallel to the front surface of the target object. In some embodiments, the first predetermined range is 35 ° to 45 °. When the included angle is the included angle on the first preset plane, the first nonstandard state indicates that the sitting posture of the target object is in a head-tilting state; when the included angle is the included angle on the second preset plane, the first nonstandard state at the moment indicates that the sitting posture of the target object is in a low head state, and the second preset plane is a plane perpendicular to the front surface of the target object.

When the included angle between a second connecting line perpendicular to the connecting line between the left shoulder key point information and the right shoulder key point information and the first preset plane is determined to be in a second preset range, determining that the sitting posture state of the target object is a second nonstandard state representing forward inclination of the body of the target object; and when the included angle between a second connecting line perpendicular to the connecting line between the left shoulder key point information and the right shoulder key point information and a second preset plane is determined to be in a second preset range, determining that the sitting posture state of the target object is a second nonstandard state representing the body side inclination of the target object. In some embodiments, the first predetermined range is greater than 30 °.

After determining the sitting posture state of the target object in each scene image, the identification unit is used for determining the number of frames that the sitting posture state of the target object in the plurality of scene images is in the first nonstandard state and/or the second nonstandard state based on the sitting posture state of the target object in each scene image; and under the condition that the frame number meets a first preset time range, determining that the user state of the target object is an abnormal state. The first preset time range can be set by a user or set by a desk lamp automatically; in some embodiments, the first preset time range may be 20s or more.

In practical application, the number of frames of the first nonstandard state and/or the second nonstandard state of the sitting state of the target object in the plurality of scene images can be determined, and then the duration of the first nonstandard state and/or the second nonstandard state of the sitting state of the target object is determined based on the number of frames and parameters of the image acquisition unit; and finally judging whether the duration meets a first preset time range, and determining that the user state of the target object is an abnormal state under the condition that the duration meets the first preset time range. For example, when the parameter of the image capturing unit is 25fps, the number of frames for determining that the sitting posture state of the target object in the plurality of scene images is the first nonstandard state and/or the second nonstandard state is 500 frames, that is, the duration for determining that the sitting posture state of the target object is the first nonstandard state and/or the second nonstandard state is 20s, and the duration satisfies the first preset time range, and then the user state of the target object can be determined to be the abnormal state.

The identification unit determines that the user state of the target object is an abnormal state when the number of frames in which the sitting state of the target object is the first nonstandard state and/or the second nonstandard state satisfies the first preset time range, because the identification unit indicates that the abnormal sitting state of the target object has been maintained for a long time when the duration of the sitting state of the target object is the first nonstandard state and/or the second nonstandard state satisfies the first preset time range. The recognition unit can change the working state of the light emitting part into a first working state for reminding the user according to the determined user state of the target object so as to prompt the target object to change the sitting posture of the target object.

In some embodiments, the identification unit is further configured to: determining, for each of the scene images, a mental state of the target object based on facial key point information of the target object in the scene image; a user state of the target object is determined based on the mental state of the target object in each of the scene images.

Here, the face key point information of the target object includes eye key point information and mouth key point information. In some embodiments, the identifying unit is configured to determine, for each scene image, whether the eyes of the target object are in the eye-closed state based on the eye-key information of the target object in the scene image; determining the number of frames in which the eyes of the target object are in the eye-closing state in the plurality of scene images based on the scene images in which the eyes of the target object are in the eye-closing state; under the condition that the frame number meets a second preset time range, determining that the user state of the target object is an abnormal state; the recognition unit is also used for determining whether the mouth of the target object is in a mouth opening state or not according to the mouth key point information of the target object in the scene image for each scene image; determining the number of frames of the mouth of the target object in the plurality of scene images in a mouth opening state based on the scene images of the mouth of the target object in the mouth opening state; under the condition that the frame number meets a second preset time range, determining that the user state of the target object is an abnormal state; the second preset time range can be set by a user or set by a desk lamp automatically; in some embodiments, the second preset time range is 20 seconds or more.

In some embodiments, the identifying unit is further configured to determine, for each scene image, a number of times that the eye of the target object is in the closed-eye state and/or the mouth of the target object is in the open-mouth state within a third preset time range, based on the eye key point information and the mouth key point of the target object in the scene image; and when the number of times is equal to or greater than the preset number of times, determining that the user state of the target object is an abnormal state. The third preset time range and the preset times can be set by a user or set by a desk lamp automatically; in some embodiments, the third preset time range is 3 minutes or less and the preset number of times is 3.

Thus, when the duration of the eye-closing or mouth-opening action of the target object meets the second preset time range, or the eye-closing and/or mouth-opening action occurs for a plurality of times within the third preset time range, the user state of the target object is indicated to be in a fatigue state (namely, an abnormal state). The recognition unit can change the working state of the luminous element into a first working state for reminding the user according to the determined user state of the target object so as to prompt the target object to rest in time.

In some embodiments, the identifying unit is further configured to determine a duration of existence of the target object based on keypoint information of the target object in each of the scene images; and determining the user state of the target object based on the presence duration.

When the recognition unit detects that the key point information of the target object exists in the scene images, the recognition unit indicates that the target object is using the desk lamp, and at the moment, the recognition unit can determine the existence time of the target object based on the key point information of the target object in each scene image; the presence duration may indicate a time of use when the user is using the desk lamp. And when the existence duration meets a fourth preset time range, determining that the user state of the target object is an abnormal state. The fourth preset time range can be set by a user or can be set by a desk lamp automatically; in some embodiments, the fourth preset time range may be 2 hours or more.

In some embodiments, the determining manner of the presence duration may be based on parameters of the image recognition unit and scene image frame numbers of the key point information of the target object in the plurality of scene images, and the specific determining manner may refer to determining a duration of time that the sitting posture state of the target object is the first nonstandard state and/or the second nonstandard state.

Therefore, when the existence duration of the target object meets the fourth preset time range, the user can be determined to be in a long-time working state and belongs to an abnormal state of fatigue. The recognition unit can change the working state of the luminous element into a first working state for reminding the user according to the determined user state of the target object so as to prompt the target object to rest in time.

In some embodiments, the identifying unit is configured to generate a first control instruction in a case where the user state is an abnormal state; the control unit is used for controlling the working state of the luminous element to be a first working state based on the first control instruction.

Here, the first operation state means that the light emitting element may flash at a certain frequency to prompt the user.

In some embodiments, the desk lamp further comprises an audio output unit, and the control unit is further configured to control the audio output unit to send out a voice prompt based on the first control instruction. Thus, when the user state is abnormal, the control unit can control the working state of the light emitting part to be changed into the first working state and/or control the audio output unit to send out a voice prompt.

In some embodiments, the user state is determined to be an abnormal state when at least one of the following occurs:

the number of frames in which the sitting posture state of the target object in the plurality of scene images is the first nonstandard state and/or the second nonstandard state meets a first preset time range;
