In order to illustrate technical solutions according to the invention, the following is a description of specific embodiments.
Embodiment one
It is the flow diagram of the eye care method of smart projector provided in an embodiment of the present invention, this method can referring to Fig. 1
With the following steps are included:
Step S101, the image in the default drop shadow spread of projector is obtained；
In concrete application, the image in default drop shadow spread can be acquired by image capture devices such as cameras, and
Image capture device can be with timing acquiring image, can also be with real-time image acquisition.
Generally, can be with timing acquiring image, and the shorter time cycle is set, it has been avoided that in this way due to acquiring in real time
There is the excessive problem of data volume in image, is also avoided that the too long caused identification of the time cycle of acquisition image is less accurately asked
Topic.Certainly, in real time or timing acquiring image, without materially affect whether to the realization of the present embodiment.
It, i.e., can be according to certain when acquired is the video flowing in the default drop shadow spread when real-time image acquisition
Time sequencing intercept a certain frame image, for example, then intercept a frame image every n frame image, n can according to time demand into
Row setting.In this case, it is understood that be timing acquiring image.
It is to be appreciated that above-mentioned default drop shadow spread refers to translating along projecting direction with the vertical plane where projector
Pre-determined distance is formed by rectangular parallelepiped space region.When pre-determined distance be equal to projector between curtain at a distance from when, then this is default
Drop shadow spread is then whole drop shadow spreads of projector, and when translation distance be less than projector between curtain at a distance from when, then should
Default drop shadow spread is then the part drop shadow spread of projector.Certainly, after above-mentioned default drop shadow spread also may include curtain
Spatial dimension, be not limited thereto.
Generally, as people apart from projector farther out when, influence of the strong light that projector is issued to human eye is smaller, therefore,
In practical applications, should make as much as possible pre-determined distance be less than projector between curtain at a distance from.In this way, can it is close in people or
When close to projector, eyeshield mode is opened, is avoided or reduced due to being closer, the strong light that projector is issued causes human eye
Harm.
Step S102, it using face recognition technology, detects and whether there is face in described image；
It is appreciated that the process of existing face recognition technology generally comprises Face datection, facial image pretreatment, face figure
As processes such as feature extraction, the identifications of facial image characteristic matching.And the face recognition technology in this step relates generally to face inspection
It surveys link and detects whether that there are faces that is, from acquired image.
It can be the detection algorithm based on Adaboost as method for detecting human face, be also possible to other detection algorithms, In
This is not construed as limiting.And corresponding Face datection process is well known to those skilled in the art, details are not described herein.
Step S103, when there are when face, detect the corresponding human body of the face and the projector in described image
Distance；
In the present embodiment, it can be human body sensing technology for carrying out technology apart from detection, can be infrared distance measuring
Technology, or others are not limited thereto apart from detection technique.
It is to be appreciated that there may also be two or more faces there may be a face in above-mentioned image.That is,
In default drop shadow spread, it is understood that there may be a people, it is also possible to which there are multiple people.When there are multiple people, then calculate separately every
Individual between projector at a distance from.
In some embodiments, above-mentioned steps 103 can be such as are as follows: utilizes infrared distance measuring technology or human body sense
Technology is answered, detects the corresponding human body of the face at a distance from the projector.I.e. using infrared distance measuring technology either people
Body induction technology is carried out apart from detection.
In addition, alleged distance also refers to the linear distance between human body and projector above, may also mean that vertically away from
From.Generally, above-mentioned distance is interpreted as the linear distance of human body and projector.
Step S104, when the distance is less than or equal to pre-determined distance threshold value, then enter eyeshield mode.
It is to be appreciated that above-mentioned pre-determined distance threshold value can be and is manually set according to actual needs, it is not limited thereto.
The distance threshold of eyeshield mode is opened, by setting with the eyeshield distance between reasonable set human body and projector.
Above-mentioned eyeshield mode can be specifically to dim projection ray, or change projection tone, it might even be possible to be to close
Projector also or is other eyeshield modes.The difference of projector type, corresponding eyeshield mode also can be corresponding different,
But this does not influence the realization of the present embodiment.
When there are multiple faces in acquired image, correspondingly, multiple distance values are also had.At this point it is possible to be all
Distance value be respectively less than when being equal to above-mentioned pre-determined distance threshold value, just enter eyeshield mode；It is small to can be the smallest distance value of numerical value
When being equal to above-mentioned pre-determined distance threshold value, then enter eyeshield mode；Be also possible to less than or equal to above-mentioned pre-determined distance threshold value away from
When reaching a certain number of from value number, just enter eyeshield mode.Under normal circumstances, each in drop shadow spread in order to preferably protect
A human eye, should can when the smallest distance value of numerical value be less than or equal to above-mentioned pre-determined distance threshold value when, i.e., when nearest apart from projector
Human body present position meet open eyeshield mode condition when, then enter eyeshield mode.
Further, it is contemplated that distance is different to the extent of injury of human eye, when human body is closer apart from projector, projection
The strong light that instrument issues is higher to human eye.Can be different at a distance from projector according to human body, correspondingly open different eyeshield moulds
Formula.At this point, above-mentioned distance threshold can have it is multiple.For example, above-mentioned distance threshold has first distance threshold value and second distance threshold value,
First distance threshold value is greater than second distance threshold value, when being less than first distance threshold value, when being greater than second distance threshold value, then opens and dims
Projection tone is changed to warm tones by projection ray；And when being less than second distance threshold value, then close projector.
As it can be seen that in the present embodiment, by face recognition technology and apart from detection, judge be in the preset range of projector
It is no with the presence of face；In the presence of judging to have face in a certain range, then eyeshield mode is opened.In this way, entering projection in people

Art.Above-mentioned pre-determined distance threshold value can be manually set according to actual needs, and can have a distance threshold, can also be had
Multiple distance thresholds.
When having a pre-determined distance threshold value, when the smallest distance value of numerical value is less than the pre-determined distance threshold value, then into eyeshield
Mode；When having at least two distance thresholds, then it can be based on when human body is closer apart from projector, the strong light that projector issues is to people
The higher situation of eye is set.For example, respectively the first pre-determined distance threshold value, second are preset there are two above-mentioned distance thresholds
Distance threshold, and the first pre-determined distance threshold value is greater than the second preset threshold, at this point, when the smallest distance value of numerical value is pre- less than first
If distance threshold, when being greater than the second pre-determined distance threshold value, then opens and dim projection ray or projection tone is changed to warm tones；And
When less than the second pre-determined distance threshold value, then projector is closed.Pre-determined distance threshold value can also there are three or more, specifically
Corresponding eyeshield measure can then be set according to the actual situation.
That is, in the presence of having multiple people in the drop shadow spread, the position locating for that people nearest apart from projector
It sets, meets the condition of eyeshield mode unlatching, then enter eyeshield mode, without just opening eyeshield after owner enters
Mode.In this way, proprietary eyes can be protected as much as possible, avoid the strong light of projector to certain closer apart from projector
The eyes of people cause bigger harm.
