Fig. 1 is a flowchart of a light adjusting method according to an embodiment of the present invention, where the method is used to adjust a light irradiation angle of a desk lamp, and the method may be executed by a light adjusting device, and the light adjusting device may be implemented by software and/or hardware and integrated in an intelligent desk lamp. The light adjusting method specifically comprises the following steps:
s100, acquiring a preset area image containing a target user;
specifically, a preset area image containing a target user is shot and acquired through a camera on the desk lamp. The preset area is a sector area which is radiated to the periphery of the desk lamp by taking a camera on the desk lamp as a base point, and in order to enable the shot preset area image to contain the image of the target user, the sector area is set to be as large as possible so as to radiate a larger range. For example, the desk lamp is placed on a desktop, and a sector area is formed at a preset angle (e.g., approximately 180 degrees) with a camera arranged on the desk lamp as a base point, and the sector area is the preset area. When a user exists in front of the desk lamp, the user is a target user, and an image of a preset area containing the target user is shot through a camera on the desk lamp. The position of the preset area in this embodiment may change according to the change of the position of the camera, and the shape and size of the preset area may not change with the change of the position of the camera after being set, and of course, the shape and size of the preset area may be set and changed by the user.
S200, determining the sitting posture orientation of the target user according to the preset area image;
specifically, the sitting posture orientation refers to a direction in which a user faces his body when sitting at a table. For example, when the user sits at a table and faces the right front, the user is in a sitting state; when the user sits in front of the desk and the body faces to the right front, the sitting posture of the user is indicated to be towards the right; when the user sits in front of the desk with the body facing to the front left, the sitting posture of the user is indicated to be towards the left. Here, the left and right directions are based on the body of the user, and the sitting posture toward the left direction means toward the left side of the user, and the sitting posture toward the right direction means toward the right side of the user.
After the preset area image is obtained, the sitting posture orientation of the target user can be identified by processing and identifying the target user image in the preset area image. When the sitting posture orientation of the target user is determined through the preset area image, the image recognition method in the prior art can be used for recognition.
For example, assume a preset area image acquired when the desk lamp is positioned directly in front of the target user. After the preset area image is obtained, firstly carrying out binarization processing on the preset area image, extracting a target user image from the preset area image, then extracting coordinate information of any point in the eye watching direction of the target user from the target user image, and finally determining the sitting posture orientation of the target user according to the coordinate information of the center point of the preset area image and the coordinate information of any point in the eye watching direction of the target user. For example, when the eye gaze direction of the target user is determined to be located on the left side of the center point according to the coordinate information of any point in the eye gaze direction of the target user and the coordinate information of the center point in the preset area image, it indicates that the sitting posture orientation of the target user is towards the right side of the target user. When the eye gaze direction of the target user is determined to be to the right of the center point, it is indicated that the target user is oriented in a sitting position toward the left of the target user.
When the preset area image is acquired, the desk lamp is not positioned right in front of the target user, the central point of the target user image is used as a reference, the eye gazing direction of the target user is determined to be positioned on the side of the target user, and then the sitting posture orientation of the target user is determined.
S300, adjusting the illumination angle of the table lamp light according to the sitting posture orientation of the target user.
Specifically, after the sitting posture orientation of the target user is determined according to the method, the illumination angle of the lamp light of the desk lamp can be adjusted left and right according to the sitting posture orientation of the target user.
For example, if the sitting posture of the target user is towards the right, which indicates that the target user needs to irradiate light towards the right side, the desk lamp rotates towards the right side of the target user to adjust the irradiation angle of the desk lamp light; if the sitting posture of the target user is towards the left, which indicates that the target user needs to irradiate light towards the left side, the desk lamp rotates towards the left side of the target user to adjust the irradiation angle of the desk lamp light.
When the irradiation angle of the table lamp light is adjusted left and right, the light source on the upper portion of the table lamp may rotate, or the supporting rod supporting the light source on the table lamp may rotate.
In this embodiment, through the preset regional image who contains the target user who obtains, confirm the position of sitting orientation of target user, then according to user's position of sitting orientation, adjust the angle of illumination of desk lamp light, after user's position of sitting orientation changes, can adjust the angle of illumination of light according to user's position of sitting orientation automatically, make the user still can obtain suitable light illumination automatically after changing work area, user's eyesight has not only been protected, and need not user's manual direction of illumination to the desk lamp and adjust, user's use experience has been improved.

When the user is in the same sitting posture, the user is photographed from the left side or the right side of the user, and there may be a difference in image characteristics of the user in the obtained image, so in order to accurately judge the sitting posture orientation of the user, it is necessary to determine the positional relationship between the target user and the table lamp.
S220, determining a corresponding target image library according to the position relation;
specifically, after the position relationship between the target user and the desk lamp is determined, the corresponding target image library is determined according to the position relationship between the target user and the desk lamp. In this embodiment, each position relationship corresponds to one image library, and each image library is used for storing an image of each sitting posture orientation in the corresponding position relationship. And if the position relation between the target user and the desk lamp is that the target user is positioned in the left front of the desk lamp, searching a target image library corresponding to the left front.
When determining the corresponding target image library according to the position relationship, a mapping table may be stored in advance, where the mapping table is used to store the mapping relationship between the position relationship and the image library, and then the corresponding target image library is determined according to the position relationship and the pre-stored mapping table.
S230, extracting an image of the target user from the preset area image;
Specifically, in order to reduce interference of noise such as a background image in the preset region image when the images are matched and improve the matching rate, binarization processing or other image processing methods may be performed on the preset region image to extract the image of the target user from the preset region image.
S240, matching the image of the target user with the image in the target image library;
specifically, the target image library stores therein various sitting posture images of the user, for example, a sitting posture image directed to the right side and a sitting posture image directed to the left side. To improve the matching rate, the sitting posture image toward the right side can be further subdivided into a sitting posture image toward the right side by 10 degrees, a sitting posture image toward the right side by 20 degrees, a sitting posture image toward the right side by 30 degrees, and the like. The sitting posture image toward the left side is subdivided into a sitting posture image toward the left side by 10 degrees, a sitting posture image toward the left side by 20 degrees, a sitting posture image toward the left side by 30 degrees, and the like. After the image of the target user is extracted from the preset area image, the extracted image of the target user can be matched with various sitting posture images stored in a target image library.
And S250, determining the sitting posture orientation of the target user according to the matching result.
Specifically, when the image of the target user is matched with a sitting posture image in the target image library, the sitting posture orientation of the target user can be determined according to the matched sitting posture image.
In the embodiment, the image library is divided according to the position relationship between the user and the desk lamp, the target image library is determined according to the position relationship between the user and the desk lamp, finally, the image of the target user is matched with the image in the target image library, the sitting posture orientation of the target user is determined according to the matching result, and the sitting posture orientation judgment accuracy can be improved.
