Description

Eye-protecting intelligent desk lamp capable of reminding sitting posture

Technical Field

The invention relates to an eye-protecting intelligent desk lamp capable of reminding sitting postures, and belongs to the field of household appliances.

Background

"Wangzhiong" and "Wang nv" are ancient idioms and still used up to now. Parents all want their children to have the most excellent results and top ranking, and to enter society from a higher starting point in the future. Thus, the increasing frequency of learning and the increasing learning pressure have led to a rare outdoor relaxation time for decades, resulting in a doubling of the domestic myopia rate. The myopia rate of primary and secondary school students (6-18 years old) in China is over 80%, wherein particularly urban students occupy most of the wall and the mountain of myopia patients. Researches show that electronic screens and dazzling light in life, particularly wrong sitting postures, too long time of using eyes, too close to eyes when people look at objects and the like are main causes of myopia. The myopia-preventing desk has the advantages that good eye using habits and sitting postures are developed, the distance between eyes and the seen objects is kept well, and especially when reading and writing are carried out, on one hand, myopia can be avoided, the myopia degree can be relieved, and even pseudomyopia can be cured.

Detailed Description

The invention is further described below with reference to the accompanying drawings.

Referring to fig. 1-2, the eye-protecting intelligent desk lamp capable of reminding a sitting posture comprises a lamp holder 1 and a lampshade 2, wherein a lighting lamp group 3 and a buzzer window 5 are arranged on the lampshade 2. The lamp holder 1 plays a supporting role, the lampshade 2 plays a containing role, the lighting lamp group 3 is arranged downwards, and a reading area is formed in a lighting area.

The lampshade 2 is internally provided with an electronic control device which is provided with a power supply circuit and a processor for carrying out centralized control, the power supply circuit provides a lighting power supply to drive the lighting lamp group 3 and other circuits of the electronic control device. The processor is connected with an image acquisition module 4 and a buzzer, the image acquisition module 4 is arranged below the lampshade 2, and the buzzer is arranged on the inner side of the buzzer window 5. Under the control of the processor 1, the image acquisition module 4 acquires images of the reading area, and the buzzer can make a reminding sound.

The processor is internally provided with a sitting posture identifying and reminding algorithm, and the sitting posture identifying and reminding algorithm comprises the following steps:

(1) the processor acquires an image f of the illumination area through the image acquisition module 4_i(x,y)=(R_i(x,y),G_i(x,y),B_i(x, y)), wherein i =1, 2, 3_i(x,y)，G_i(x, y) and B_i(x, y) are the red, green and blue components of the image, respectively;

(2) calculating R_i(x,y),G_i(x,y),B_iMinimum Min among (x, y)_i(x, y), and then the saturation S is calculated_i(x,y)=1-3Min_i(x,y)/(R_i(x,y)+G_i(x,y)+B_i(x, y)), luminance I_i(x,y)=(R_i(x,y)+G_i(x,y)+B_i(x,y))/3；

The brightness I_i(x, y) and saturation S_i(x, y) is used to determine whether the photographic subject is black, specifically, a subject with low brightness and low saturation.

(3) When the condition S is satisfied_i(x,y)<S_T，I_i(x,y)<I_TAnd then the processor judges that the current pixel point (x, y) is dark and is marked as F⁰ _i(x, y) =1, otherwise F⁰ _i(x, y) =0, wherein S_TIs a saturation threshold, I_TIs a brightness threshold;

step (3) image f_iThe black areas in (x, y) are identified and stored in F⁰ _i(x,y)。

(4) To F⁰ _i(x, y) is subjected to corrosion expansion to obtainTo image F¹ _i(x,y)；

Step (4) etching F⁰ _iFiltering the isolated and stray points in (x, y), combining the isolated area and the pixel points after corrosion through the expansion process to form a whole area, and finally storing the whole area in F¹ _i(x,y)。

(5) Statistics F¹ _iThe number N of non-zero pixel points in (x, y)_iIf N is present_i>And T, the processor judges that the sitting posture of the user is incorrect, and controls the buzzer to generate a reminding sound, wherein T is a judgment threshold value.

If the sitting posture is incorrect, the distance between the eyes and the desktop is too short, the image acquisition module 4 acquires the image of part of or the whole head, and therefore F¹ _i(x, y) there will be large non-zero pixel areas, number N_iCan be used as an effective parameter for judging sitting posture.
