Preferably, the determining a second adjustment coefficient U2 for currently adjusting the light source according to the current lighting environment of the target child includes:
acquiring the illumination intensity of the current illumination environment and the color information of the indoor wall;
and obtaining the second adjusting coefficient according to the illumination intensity and the color information and a mapping table of a pre-constructed illumination environment and a second adjusting coefficient U2.
Preferably, the mapping table is configured to establish a one-to-one correspondence relationship with the second adjustment coefficient after weighted combination of a first weight based on a plurality of illumination intensity data and a second weight of each color.
Preferably, the HSV pathway image includes: hue H, saturation S and lightness V, wherein H ranges from 0 to 180 degrees, saturation S ranges from 0 to 1, lightness V ranges from 0 to 255, the color information is obtained by calculating the average brightness of a channel S in the HSV image, and the calculation formula is as follows:
W1＝Sum(Mi*N(i))
where Mi is the S channel value, represented as a floating point value from 0 to 1, and N (i) is the number of points in the image with a saturation of Mi.
The illumination intensity in the adjustment parameter is obtained by calculating the average brightness W1 of the current V channel, and the specific calculation formula is as follows:
W2＝Sum(Pi*Q(i))
wherein Pi is the pixel value in the V channel and represents an integer pixel value of 0-255, and Q (i) is the number of points in the image corresponding to the pixel value Pi.
Preferably, the first adjustment factor U1 is calculated as follows:
(1) If the current behavior state of the target child in the child room is recognized as a learning activity, considering that strong illumination is needed during learning, in an HSV channel image, the average brightness of a V channel needs to be improved, a weight coefficient a is added to the average brightness, wherein a is greater than 1, if the learning activity is not recognized, a =1, and the adjusted illumination brightness is calculated as:
Wnew＝W1×a
wherein the value range of a is preferably between 1.0 and 1.15.
(2) If the target child is identified to perform entertainment in the child's room, the illumination intensity also needs to be increased, so a weight coefficient b is added to the average brightness of the V channel, where b >1, and if the entertainment is not identified, b =1, and the adjusted illumination intensity is calculated as:
Wnew＝W1×b
wherein the value range of b is preferably 1.0-1.1, which can better satisfy the atmosphere of entertainment activities.
(3) If it is recognized that the rest (including sleep) is performed, considering that the rest is affected by the brighter room of the child when the rest is performed, the illumination brightness can be reduced, so a weight coefficient c is added to the brightness of the V channel, where c is less than 1, and since the rest flame is mainly blue and yellow, a positive increase is generated for the saturation S in the HSV channel, a weight coefficient d is added to the average saturation, where d is less than 1, if the rest is not recognized, c =1, d =1, and the adjusted average brightness is:
Wnew＝W1×c
Snew＝S×d
here, c is generally set in the range of 0.85 to 0.95, and d is generally set in the range of 0.80 to 0.95, which is preferable.
In addition, in some scenes, the problem of definition of indoor scenes is also considered, because when the acquired images are not clear, the processing of the subsequent HSV channel images is not favorable. For the definition, mainly considering the calculation of a Sobel edge image of a V-channel image and the calculation of an average gray value S of the Sobel edge image, the Sobel edge image is obtained by performing convolution operation on the image by using a Sobel operator of 3 multiplied by 3. Wherein, the image with the average gray value S more than or equal to 1.0 is a clear image, and the corresponding coefficient e is calculated by the following method:
if S≥1,e＝1
if S<1,e＝0.9
when the image is clear, the illumination in the scene is uniform, no obvious strong reflection light or local astigmatism exists, the adjustment coefficient is 1, and the image does not need to be modified; when the scene is blurred, the brightness of the scene needs to be reduced, the reflection or diffusion intensity needs to be reduced, and the adjustment coefficient e is smaller than 1.
Preferably, the regulation formula of the HSV channel is as follows:
if S≥1.5×Sstd,S＝Sstd
else S＝W2×d
if V≥1.5×Vstd,V＝Vstd
else V＝W1×a×b×c×e
wherein Sstd and Vstd are standard values calculated by testing under multiple illumination conditions.
In one embodiment, according to the relationship between the light source parameters and the HSV channels, the calculation method is to fit a functional relationship f1 (S) between the average brightness value of the S channel and the current corresponding color temperature value of the light source and a functional relationship f2 (V) between the brightness value of the V channel and the current corresponding color temperature value of the light source under different illumination and color temperatures.
In one embodiment, pictures collected in the children room need to be classified, and the classification method preferentially adopts a Resnet classification model to classify and judge scenes in the children room.
Preferably, the current adjusting coefficient U1 is calculated by adopting a method based on picture classification in the activities of learning, entertainment and rest.
In the embodiment of the invention, when the light source parameters are adjusted, the adjustment of the color temperature and the brightness value is mainly considered, and the corresponding brightness and color temperature values can be obtained by adopting the f1 (S) and f2 (V) for calculation.
In addition, due to the natural liveliness of the children, when the children are switched among different behavior states in the children room, the invention also has a gradual change process of the adjusting parameters of the light source, the gradual change can make a more accurate gradual change decision of the light source according to the behavior state change and whether the children wear glasses, the decision is an intelligent decision, and can be a gradual change decision of the light source according to a mathematical model after a plurality of groups of data are obtained in a big data mode in advance. The present invention will be described herein in terms of light source regulation for healthy lighting with a full spectrum light source.
When it is determined that the target child is transitioning from a learning activity to an entertainment activity, then a direct transition from the second illumination intensity and the second color temperature to the first illumination intensity and the first color temperature may be significantly uncomfortable to the eye, and may also affect the performance of the entertainment activity during such a hard transition. In order to solve the problem, the light source of the invention is a full-spectrum light source, at the second illumination intensity and the second color temperature, the second color temperature is adjusted to gradually decrease and transition to the first color temperature within the first preset time, and then the second illumination intensity is correspondingly adjusted within the second preset time. The adjustment can also be carried out simultaneously, but at the moment, a plurality of discrete combinations of the illumination intensity and the color temperature are arranged in the middle, but the combined change of the two adjacent discrete combinations of the illumination intensity and the color temperature is in a range which can not be obviously perceived by human eyes.
In one embodiment, when there are more than two children, only one of the children can be targeted unless all of them are in the state of restful sleep, which is the first judgment condition. The invention provides a mode which can be accepted by most people for determining the target children:
determining the current behavior states of all children;
according to the current behavior state of the children, the learning and entertainment in the behavior state are sequenced according to the priority;
when a child is in a learning activity, the child wearing the glasses is taken as a target child;
when there is no child at the learning activity, a child wearing glasses among children at the entertainment activity is targeted. This selection ensures that all children are visually good.
