The display of all depth of field positions is effectively set on diagram picture.
The setting that the method for calculating and setting shows the depth of field is converted into mathematical computations, provides a kind of setting side of simplicity
Method its advantage lies in being able to quickly draw the display data of the depth of field.But since error unavoidably occur in mathematical computations, not necessarily
High definition can be met to show and the display requirement of the accurate depth of field, in addition can not be intuitive to see the effect that the depth of field is set.In order into one
Accurate depth of field display effect is walked, the scheme of laser setting may be employed in we.
When carrying out laser setting, we calculate the angle of left and right an eye line according to depth of field data, and calculate sight
Angle corresponding graduation position D1, D2.Virtual direction of visual lines can also be simulated, according to sight extended line and graduated scale 144
Intersection point determine D1, D2 position.Two observation eyepieces 23 in adjustment left and right make the laser that its top laser 24 emits correspond to respectively
D1, D2 position of graduated scale 144 are got to, the intersection point E of two laser and theoretic depth of field position are in same plumb line at this time
On.4 order display screen 16 of processing unit shows detection information, and first, display screen 16 is in units of column of pixels from display screen 16
First end show longitudinal light by column to second end, first end and second end is opposite, can artificially specify as needed, generally
In the case of we specify in terms of from observation unit 2 to the direction of the test cell 1 after fixation, the left end of display screen 16 is first end,
Right end is second end, when elementary area 3 detects that the display information of display screen 16 reaches the calibration of observation unit 2 after distortion
During position, elementary area 3 carries the information to processing unit 4, and processing unit 4 records the abscissa position of light in display screen 16 at this time
It puts, which is the abscissa positions that display screen 16 correctly shows the depth of field, since display screen 16 is during display
It is shown respectively at left and right sides of point, two images being visually observed in corresponding left and right, therefore abscissa positions under the same depth of field
There are two, two observation eyepieces 23 are corresponded to respectively.After the abscissa positions of the correct measurement depth of field, display screen 16 is with entire row of pixels
Transverse light rays are shown line by line to lower end from the upper end of display screen 16 for unit, when elementary area 3 detects the display of display screen 16
When information reaches the calibration position of observation unit 2 after distortion, elementary area 3 carries the information to processing unit 4, processing unit
4 record the ordinate position of light in display screen 16 at this time, which is that display screen 16 correctly shows the vertical of the depth of field
Coordinate position, similarly, ordinate position is also two under the same depth of field.Corresponding display abscissa of depth of field and ordinate are at this
It determines.Then observation unit 2 moves to next point of observation, and 4 order test cell 1 of processing unit shows detection information, repeats
Above-mentioned detection process.Until measurement in need the depth of field all obtain measurement until.The calibration position of observation unit 2 can basis
It needs to specify, the center that measurement will generally demarcate position and be arranged on the captured image of observation unit 2 for convenience can be with
The target center of one fixed width around the position is set, the display information of display screen 16 is can consider when luminous point image falls in target center
The calibration position of observation unit 2 is reached after distortion.
Human eye has opposite choice when observation shows image, when eyes adjustment focal length watches some object,
Other images different from the object depth of field will become Relative Fuzzy, this is the behavior that the mankind are formed during evolution.Cause
This is when showing image, if all carrying out depth of field setting, entire picture all right and wrong using the method that laser is set
Often clearly, false sensation can be so caused, influences the feeling of immersion of virtual reality.Therefore we need when setting the depth of field
Fuzzy Processing is deliberately carried out to the image of some vision edge positions, to form relatively real image scene.We use
Laser sets the mode being combined with calculating and setting to carry out this processing.First, when image needs to set the depth of field, we are right
It is divided in image, marks off accurate setting area and general setting area.Accurate setting area and general setting area
Criterion is mainly divided by mainly showing object and the display object closely located with main display object depth, due to
Main display object is often subject to the more concern of observer, therefore the image of main display object covering during display
Region is accurate setting area.Due to the relation of the depth of field, show that object also can be relatively clear similar in object depth with main show
It is clear, therefore this part shows that object also falls within accurate display area.It can be set not to meet more accurate display requirement
The accurate display area of same level, this can voluntarily be set according to demand by developer.Mark off accurate setting area and
Behind general setting area, accurate setting area carries out depth of field setting using the mode that laser is set, and general setting area utilizes
The mode of calculating and setting carries out depth of field setting.So not only save the time, but cause accurate setting area the depth of field show compared with
High display quality.Fuzzy processing is carried out to image after the depth of field is provided with, fog-level can be according to the accurate of setting
The different stage of setting area and accordingly set.The processing of image is accused and completed after the completion of Fuzzy Processing.
Compared with prior art, the present invention causes the display of image to be more nearly people using by the method in image division region
The scene that eye is actually seen enhances the feeling of immersion of virtual reality.By the division of accurate setting area and general setting area,
The Efficiency and accuracy of depth of field setting is effectively improved using the different depth of field plans of establishment for different zones.It provides sharp
Light is set and two kinds of depth of field setting methods of calculating and setting, the setting for making the depth of field are more convenient.The present invention is using according to depth of field relation
The correspondence position on graduated scale 144 calculated beats the method in 144 correspondence position of graduated scale using the transmitting laser of laser 24
The formation of the depth of field is simulated, can intuitively confirm depth of field position.Observation by the observation eyepiece 23 being connected with laser 24, really
The corresponding display abscissa in the image depth position adjusted and display ordinate are needed calmly, provide a kind of upper side that the depth of field is set
Method, it is convenient and easy.The image for by setting calibration position processing unit being allow to observe observation eyepiece 23 differentiates, sentences
Breaking, whether it meets the requirement of the depth of field.View directions are calculated by depth of field relation, calculate the correspondence position of graduated scale 144.
When theoretic luminous point and actual luminous point, there are during error, can directly utilize the amendment of theoretic luminous point position actual
The position of luminous point ensures that the depth of field meets preset requirement.Utilize test cell 1, observation unit 2, elementary area 3 and processing unit
4 combination effectively simply solves the problems, such as depth of field verification.By motor 27 observation unit 2 is driven to be transported along eyepiece track 25
It is dynamic, it can facilitate from multiple angles from carrying out, to facilitate the setting of multiple points of observation.
