Description
Technical field
The present invention relates to a kind of pre- myopia prevention device of the wear-type based on stereoscopic vision and behavioural analysis, belong to computer and regard
Feel technical field.
Background technology
Adolescent myopia is the very big social concern that we face at present, and the generation of myopia is frequently due to see
The posture of book/computer is not right, and eye distance target is excessively near, the reason such as the overlong time and illuminating ray of reading/computer are dim
Cause.The occurrence of how effectively monitoring above-mentioned, so that effective pre- myopia prevention is a problem demanding prompt solution.
Have by ultrasonic wave or the infrared pre- myopia prevention device found range and reminded at present, but such device is only
The distance of drawing axis object distance eyes can be measured, and cannot judge whether object at the moment is book/computer, when user at the moment
Object when not being book/computer, or user be not carry out reading activities and when simply having book/computer at the moment, such device
Will be reminded, interference and inconvenience are brought to the life of user；Simultaneously user computer of reading a book/see/with mobile phone etc. difference field
, it is necessary to different reading distance and reading interval under scape, device before cannot automatic decision be which kind of reading scene, it is impossible to from
Dynamic is configured, and the use to user is made troubles.
In order to overcome the problem above of current pre- myopia prevention device, we have proposed one kind based on stereoscopic vision and behavior point
The pre- myopia prevention device of wear-type of analysis.By the device can with the distance of automatic measurement eye distance book/computer/Pad/ mobile phones with
And judge the behavior of user, if user is in reading/with computer/with Pad/ mobile phones, if the distance of eye distance target
Cross near, then may remind the user that, correct posture；The computer/with the overlong time of Pad/ mobile phones if it is determined that user reads/uses,
Or light in scene is excessively dark, it is also possible to remind user；Simultaneously the device can automatic decision be currently which kind of reading activities, root
Relevant parameter can be automatically set according to different reading activities, pre- myopic-preventing purpose can be effectively accomplished.
The content of the invention
Occur the invention aims to effectively pre- myopia prevention, it is proposed that a kind of based on stereoscopic vision and behavioural analysis
The pre- myopia prevention device of wear-type.
A kind of pre- myopia prevention device of wear-type based on stereoscopic vision and behavioural analysis, the abbreviation present apparatus, mainly by binocular
Camera, wireless module, computing module and prompting module composition.
Wherein, wireless module connects computing module by wireless network, and the image transmitting that binocular camera is obtained is to meter
Module is calculated, while the result that will be calculated and analyze sends prompting module to；
Wherein, wireless network is the LAN with wireless transmission function and related protocol, WiFi or Metropolitan Area Network (MAN)；
Computing module receives the image that binocular camera is obtained by wireless network, and carries out stereo restoration and behavior point
Analysis, stereo restoration and the result of behavioural analysis send prompting module to by wireless module afterwards；Prompting module is extensive according to solid
The result of multiple and behavioural analysis reminds user to keep at a distance by way of based on voice and vibrations, appropriateness rest or increase are illuminated
With pre- myopia prevention.
The present apparatus is worn on a user's head when in use, wherein, the eye position for being closely located to user of binocular camera.
It is as follows based on the pre- myopic-preventing concrete operation step of the present apparatus：
Step one, the present apparatus, by demarcating, determine the inside and outside parameter of binocular camera using preceding；
Step 2, binocular camera obtain two-way scene image, and computing module is sent to by wireless module；
Step 3, computing module are based on the three-dimensional information of the two-way image restoration scenario for obtaining and user behavior are divided
Analysis, and corresponding operating is carried out according to analysis result；
Wherein, the three-dimensional information of restoration scenario refers to the three-dimensional information for recovering scene point corresponding to every bit on image, right
It refers to judge whether user is being read that user behavior is analyzed, and whether reading time long, eyes with read correlative
Whether excessively whether near and scene lighting is suitable for body distance, and it refers to that user is reminded to carry out corresponding operating according to analysis result
Or return to step two reacquires two-way scene image；Step 3, specially：
The two-way scene image that step 3.1 is obtained according to binocular camera, in obtaining two images by Stereo matching
Corresponding points, draw stereo matching results；
The inside and outside parameter of the binocular camera that step 3.2 is obtained according to step one, by the method for trigonometric ratio to step 3.1
The stereo matching results of output are processed, and obtain the three-dimensional information at scene midpoint；
Step 3.3 is analyzed to user behavior and carries out corresponding operating for behavioural analysis result, specially：
Detect that book, computer, Pad and mobile phone etc. read related object in the picture by object detecting method, and work as
After detecting this type objects, judge whether the distance of such object distance user keeps stabilization, entered according to the result whether stablized
Row reading time measures and reminds or the reacquisition two-way scene image of return to step two, specially：
If the distance that 3.3A books, computer, Pad and mobile phone etc. read related object distance user is more stable and continue one
The section time, then it is considered that user is in reading/with computer/with Pad/ mobile phones；Now, in the scene for being obtained according to step 3.2
The distance of the three-dimensional information of point and the testing result of book, computer, Pad or mobile phone, measurement user and target, and obtained according to measurement
Distance, decide whether to point out user by way of prompting module is with sound or vibrations；And it is further according to reading time
The time of realization successively decreases intensive prompting；
Wherein, continue for some time and be defined as greater than being equal to 30 seconds；
Wherein, time intensive prompting of successively decreasing refers to reading/with computer/holding with Pad/ mobile phone time of the act
It is continuous, the increased prompting frequency of index is set；Simultaneously with reading behavior continue and scene image real-time analysis result, to
Family illumination is accordingly reminded；
If the distance that 3.3B books, computer, Pad and mobile phone etc. read related object distance user is unstable and also not lasting
For a period of time, then it is considered that user jumps to step 2 in reading/use computer/with Pad/ mobile phones；
So far, from step one to step 3, complete based on the pre- myopic-preventing concrete operations of the present apparatus.
Beneficial effect
The pre- myopia prevention device of a kind of wear-type based on stereoscopic vision and behavioural analysis, compared with prior art, with such as
Lower beneficial effect：
The present invention is a kind of wear-type device, can anywhere or anytime detect the reading of user/with computer/with Pad/ hands
Machine behavior；Corresponding parameter is automatically set according to different behaviors, more preferable pre- myopic-preventing generation, while will not be read to non-
Reading behavior is judged by accident and disturbed, user-friendly.
The present apparatus can anywhere or anytime remind user to be kept for good reading distance and appropriate reading time；
The present apparatus can also remind user to keep good reading lighting, effective pre- myopic-preventing generation.
