Detailed description of the invention
Fig. 1 is the structural schematic diagram of the intelligent glasses of the embodiment of the present invention 1.
Fig. 2 is another structural schematic diagram of the intelligent glasses of the embodiment of the present invention 1.
Fig. 3 is the flow chart of the file encrypting method of the embodiment of the present invention 2.
Specific embodiment
The present invention is further illustrated below by the mode of embodiment, but does not therefore limit the present invention to the reality
It applies among a range.
Embodiment 1
Referring to fig. 2, the present embodiment provides a kind of intelligent glasses, the intelligent glasses include one for being fixed on user's head
Wearing main body, the wearing main body be frame 11, the intelligent glasses further include one be set to the frame on the inside of eyeball chase after
Track device 12, a photographic device 13 and a processing module.
The photographic device includes a camera and a rotating device.
The camera lens that the rotating device is used to adjust the camera is axial.
The eyeball tracking device includes an acquisition camera lens being fixed on the frame, and the acquisition camera lens is for acquiring
Eyeball axis direction 121 and eyeball apical position 122 (pupil position) when user looks squarely is using as initial axis and initial bit
It sets.
The acquisition camera lens is also used to acquire active user's eyeball apical position 123 using as current location.
The processing chip is used to obtain current axis 124 according to the initial axis, initial position and current location, and
It is axial that the camera lens is adjusted according to rotating device described in the current axial line control.
Referring to fig. 2, the acquisition camera lens is set to inside the frame position that can be directed at eyeball pupil to specific algorithm, by
It is all different in the eyeball position of each user, interpupillary distance, bridge of the nose height, user calibrates in first wear, to adopt
Collect the initial position of user eyeball.
The acquisition camera lens can obtain the position of pupil 122, that is to say, that the acquisition camera lens can obtain pupil 122
It, can by calculating with the angle 127 of plane where the length and the line segment and eyeglass of acquisition 125 line formed section 126 of camera lens
To obtain initial projections point 128 of the pupil on lens plane, i.e. eyeball center 129, pupil 122 and initial projections point
128 place straight lines (initial axis) are vertical with lens plane 141.
When user eyeball watches certain point attentively, eyeball center 129 and current 123 place straight line 124 (current axis) of pupil
It can be with initial axis at an angle 142 to be measured.Current the distance between pupil 123 and the acquisition camera lens 125 (current line segment)
And the angle of current line segment and lens plane can be obtained by eyeball tracking device.In current pupil, the acquisition camera lens
And in right angled triangle composed by current projection of the pupil on lens plane, it is known that the length of the hypotenuse and angle can be with
Two right-angle sides are calculated, obtain current pupil to lens plane distance.
Under the premise of eyeball radius 144 is essentially identical, the radius length of available eyeball, eyeball center 129, when
Preceding pupil 123 and current pupil are in the triangle composed by the projection 145 on initial axis, the length of the hypotenuse (eyeball radius)
With a right-angle side (eyeball center to lens plane distance subtracts current pupil to the distance of lens plane) is known to be calculated
The angle to be measured 142, according to the information of current axis, handles chip controls so as to obtain the information of current axis 124
The rotating device adjusting camera lens axially arrives parallel with the current axis direction.
Since camera lens can rotate adjustment angle, to make user that need not rotate body, neck to look for shooting angle, make to clap
It is more convenient to take the photograph process.
The eyeball tracking device is also used to acquire the pupil information of user's pupil size, and the processing chip is also used to root
The focal length and exposure of the photographic device shooting image are controlled according to the pupil information.
The wearable device further includes a logging modle, and the logging modle is used to record 1 second before current time axis
Line information.
The eyeball tracking device is also used to detect user's blink information.
The processing chip is for controlling the photographic device root when number of winks is 2 in blink information satisfaction one second
Image is shot according to the first 1 second axis information.
The intelligent glasses of the application can be shot by capturing number of winks, keep shooting process more convenient.
Using above-mentioned intelligent glasses, the present embodiment also provides a kind of image pickup method, and referring to Fig. 3, the image pickup method includes:
100, eyeball axis direction when acquisition user head-up and eyeball apical position are using as initial axis and initial bit
It sets.
101, the eyeball apical position of acquisition camera lens acquisition active user's eyeball is using as current location.
102, current axis is obtained according to the initial axis, initial position and current location.
103, record current time before 1 second current axis information.
104, detection user blink information controls the camera shooting and fills when number of winks is 2 in blink information satisfaction 1 second
It sets and image was shot according to 1 second before current time axis information, shooting the mode of image is the processing chip according to institute
State current axis information control the rotating device camera lens of the camera is adjusted axially it is parallel with current axis, and
The focal length and exposure of the photographic device shooting image are controlled according to the pupil information.
Embodiment 2
The present embodiment is substantially the same manner as Example 1, the difference is that only: the photographic device includes a wide-angle imaging
The intelligent glasses of head, the present embodiment are shot after getting shooting signal using wide-angle camera to obtain wide-angle view,
Position after shooting using current axis intercepts the picture of specified size on wide-angle view.
Concrete mode is, using the horizontal component and vertical component of the available angle to be measured of angle to be measured,
Using the center of the wide-angle view as coordinate origin, horizontal component and vertical component respectively correspond the transverse and longitudinal of the coordinate system
Coordinate is to obtain the higher image of quality.
Although specific embodiments of the present invention have been described above, it will be appreciated by those of skill in the art that these
It is merely illustrative of, protection scope of the present invention is defined by the appended claims.Those skilled in the art is not carrying on the back
Under the premise of from the principle and substance of the present invention, many changes and modifications may be made, but these are changed
