Embodiment one
The embodiment of the present application provides a kind of method of shooting stereo image, as shown in Figure 1, method packet provided by the present application
It includes:
Step 11: the first probing light of transmitting, it is true according to the first probing light by subject reflection received
Determine the first distance information of subject, the first distance information is three-dimensional for characterizing the subject and shooting
The distance between device of image.
Stereo image shooting is carried out by video camera in application scheme embodiment, subject is sphere.This step
In 11, the first distance information is used to characterize the position of the subject, specifically, first distance information can be
One coordinate points, region or other be used to characterize the data information of position.In this example, first distance information be sphere with take the photograph
The distance between camera lens.
Specifically, can emit first probing light by infrared module, the infrared module, which can be, to be set to
Light emitting module inside video camera, for emitting infrared light, which may include near infrared light, also may include
Far red light.The wavelength of infrared light is typically larger than 770 nanometers, and less than 1 millimeter, infrared light has preferable penetration performance.
Since its wavelength is longer, light-wave energy is not easy to lose in communication process, can be shot in the environment such as night, underwater.
Therefore, stereo image shooting is carried out using infrared light, energy consumption can not only be reduced, moreover it is possible to be suitable for a variety of shooting environmentals, application
Range is wide.
Above-mentioned infrared module specifically can be Infrared laser emission pipe array, can specifically include the multiple of array arrangement
Infrared light-emitting diode, the infrared light-emitting diode are alternatively referred to as infrared diode.Above-mentioned first probing light is for detecting
The position of subject.When the first probing light is infrared light, the intensity of the infrared light of transmitting should be greater than environment light
In infrared light intensity.Infrared light difference to be subsequently received and the infrared light in environment light, avoid environment light
Line has an impact the ambient light received.
Under normal conditions, the infrared light in environment light is related with many factors in environment, for example, in sunshine abundance
Outdoor, the infrared light in environment light is often stronger, and in dark lighttight interior, the infrared light in environment light is past
It is past weaker.The intensity of the first probing light emitted in the application can be preset according to actual photographed environment.
Preferably, before above-mentioned steps 11, as shown in Fig. 2, the above method further include:
Step 15: with the first preset strength emission detection light, if received reflection light does not meet ranging requirement, with
Second preset strength emits the first probing light, and second preset strength is greater than first preset strength.
Above-mentioned first preset strength can be preset according to actual needs, be wanted if received reflection light meets ranging
It asks, then can emit the first probing light according to the first preset strength.If the reflection light received does not meet ranging and wants
It asks, then the first probing light is emitted with the second preset strength for being better than the first preset strength.Second preset strength can be camera shooting
The maximum intensity that function issues, is also possible to preset intensity according to actual needs.
Ranging requirement in this step, can specifically refer to: the reflection light received is better than ambient light.Work as reception
To reflection light be better than ambient light when, can guarantee that ranging is accurate in subsequent step.When the reflection light received close to
It carries out being easy to produce error when ranging when ambient light, in subsequent step.
Technical solution provided by the present application can primarily determine the emissive porwer of the first probing light, and then improve subsequent step
The accuracy of the first distance information of the shooting object determined in rapid, reduces range error.And then it improves in subsequent step and determines
Second distance information accuracy, improve the clarity of the stereopsis of generation.
Infrared light is reflected in subject close to the surface of video camera, and the infrared light of reflection, which travels to, to be taken the photograph
Camera, specifically, the infrared light of reflection can be received by photosensitive element (Charge-coupled Device, CCD).It should
Photosensitive element can be arranged in video camera with array structure to be multiple.
Specifically, the time span by the infrared light S1 of video camera transmitting is Tp, the corresponding shade table of Tp referring to Fig. 3
Levy the power consumption of infrared light-emitting diode.The power consumption of the infrared light-emitting diode corresponds to the intensity of infrared light, therefore, in figure
Region shown in shade can characterize the intensity of the infrared light of video camera transmitting.
Above-mentioned time span Tp can be understood as the time span of infrared light-emitting diode unlatching, in Fig. 3, when high level
Light emitting diode opens (luminous), and light emitting diode turns off (extinguishing) when low level.
Corresponding with the time span that light emitting diode is opened, photosensitive element is opened in above-mentioned time span Tp, that is, is existed
Above-mentioned photosensitive element is photosensitive by camera lens in the Tp period, is reflected back video camera to receive from subject
Infrared light.As shown in S2 in Fig. 3, since light reaches subject from camera, then is reflected and reached by subject
During camera, infrared light propagation needs elapsed time, therefore, compared with the infrared light of transmitting, receives infrared
The time of light, there are delay time length Td, time span Td, that is, infrared light compared with the time of transmitting infrared light
Travel to and fro between the time between camera and subject.The energy for the infrared light that shade characterization in S2 receives, is based on
Light velocity c, (1) is it is estimated that the distance between video camera and subject surface according to the following formula.
Technical solution provided by the present application can primarily determine the position of subject, by the side for emitting infrared light
Formula calculates the approximate location of subject according to the time that infrared light is propagated.The above method is convenient and efficient, accuracy compared with
It is high.Infrared light-emitting diode used in this programme and CCD photosensitive element both can be used for determining subject in this step
Position, can also further determine that the surface shape of subject, the process of shooting stereo image in a subsequent step
In can use identical hardware, using excessive hardware device when avoiding shooting stereo image, so that it is whole just to improve scheme
Victory.
Step 12: determining the emissive porwer of the second probing light according to the first distance information of the subject, send out
The second probing light is penetrated, second probing light is used to detect the surface shape of the subject.
Specifically, above-mentioned second probing light can be sent by infrared module, during infrared light is propagated,
It inevitably can be causing energy attenuation due to colliding, scatter etc., so that the energy of the infrared light received is lower than and to launch
The energy of infrared light.If the energy for the infrared light launched is lower, and the infrared light energy in environment light is higher,
The energy for being then likely to result in the infrared light received is close with the energy of environment light, cause the infrared light received by
It then handles to obtain by the infrared light received to the influence of environment light so that the infrared light that video camera obtains is unintelligible
Data and accuracy of information it is not high so that generate stereopsis it is unintelligible.So for apart from the farther away quilt of video camera
Object is shot, it, can be with the higher probing light of emitted energy, in the present solution, should according to the intensity of environment light mid-infrared light line
Probing light can be infrared light.
And for apart from the closer subject of video camera, since infrared light travels to and fro between video camera and subject
Distance between body is shorter, and the amount of energy attenuation is less, so that the energy of the infrared light of transmitting and the infrared light received
Energy it is close.If the energy of the infrared light of transmitting is higher, the energy of the infrared light received is apparently higher than environment light
Line, it will cause energy wastes.In fact, the difference of the infrared light in the infrared light received and environment light reaches one
Determine preset value, the infrared light received is enabled to be different from ambient light.Therefore, for closer apart from video camera
Subject can be with the lower probing light of emitted energy, so that receiving according to the intensity of the infrared light in environment light
To infrared light can be distinguished with the infrared light in environment light.
Referring to Fig. 3, the energy of the area attribute probing light in figure shown in shade, therefore, lengthening pulse width can be mentioned
The energy of the infrared light of high-incidence injection, similarly, chopped pulse width can reduce the energy for the infrared light launched.
In the present solution, determining that the pulse of the second probing light of transmitting is wide according to the first distance information of subject
Degree, i.e., the energy value of the second probing light of controllable transmitting.For apart from farther away subject, pulse width is wider,
I.e. the opening time is longer；For the subject being closer, pulse width is relatively narrow, i.e. the opening time is shorter.
Scheme provided by the present application is for guaranteeing apart from the farther away higher infrared light of subject emitted energy
The infrared light received can be different from the infrared light in environment light, for the subject emitted energy being closer
Lower infrared light, on the basis of guaranteeing that the infrared light received can be different from the infrared light in environment light, moreover it is possible to
Power consumption is further decreased, energy-efficient effect is reached.
Step 13: determining that the second distance of the subject is believed according to the part of reflection second probing light
Breath, the second distance information are used to characterize the surface shape of the subject.
After the probing light launched reaches subject surface, transmitting reflection is propagated back to the position where video camera,
The probing light of reflection can be received by CCD photosensitive element.Due to transmitting probing light at the time of with received probing light
At the time of there are differences, the distance between subject and video camera can be calculated according to above-mentioned formula (1).
When in video camera including the CCD photosensitive element of array arrangement, each photosensitive element passes through the above method
The distance between subject and video camera are calculated, can be obtained multiple distance values of array arrangement.These array arrangements
Distance value can characterize the surface shape of subject.The quantity of CCD photosensitive element in video camera is more, camera shooting
The surface shape for the subject that machine obtains is more clear, these the second probing lights received by multiple CCD photosensitive elements
The information that processing obtains is above-mentioned second distance information.
Step 14: the stereopsis of the subject is generated according to the second distance information.
Due to include in second distance information characterize subject surface shape information, according to second away from
Subject can be generated close to the stereopsis of video camera side from information.
Specifically, may include the multiple range informations for having array arrangement in second distance information, each information can be right
It should be in a pixel of the stereopsis of generation.When CCD photosensitive elements multiple in video camera are arranged as rectangular array structure
When, then calculating the second distance information obtained also can wrap multiple distance values containing array arrangement, when each distance value pair
The rectangle stereopsis of above-mentioned subject should then can be generated when a pixel of stereopsis.
Technical solution provided by the present application primarily determines the approximate location of subject first, and then basis is determined
Position determine transmitting the second probing light intensity, determine subject further according to the second probing light of reflection
Surface shape, the last stereo-picture that subject is generated according to the surface shape determined.Technical side provided by the present application
Case is able to achieve stereo image shooting.In shooting process, the second probing light is emitted according to the range information of subject,
It can guarantee that the second probing light intensity after being reflected by subject is better than ambient light, improve the clarity of stereopsis,
Be able to achieve subject distance farther out when guarantee image-capturing resolution, when subject is closer, guarantee shoot
Shooting energy consumption is reduced under the premise of clarity.
The method based on the above embodiment, the method also includes:
When the second distance information and the first distance information meet preset condition, described clapped is redefined
The range information for taking the photograph object updates the first distance information according to new range information.
Under normal conditions, the first distance information and the time interval of second distance information got is shorter, subject
The surface shape of body tends not to that there are excessive differences.In the present solution, above-mentioned first distance information and second distance information are equal
It is to be calculated and determined with the time difference for receiving probing light according to transmitting, by the time difference for emitting and receiving probing light
The relative position between subject and video camera can be calculated.
In the present solution, can according to first distance information calculate subject between video camera at a distance from, can also
With according to second distance information calculate the distance between subject and video camera, if two be calculated apart from base
This is identical, then can be considered and obtaining first distance information and obtaining in the time between second distance information, video camera with clapped
The relative position for taking the photograph object does not have significant change.In this case, due to being sent out according to first distance information in above scheme
Penetrate probing light, then according to the probing light of reflection obtain second distance information, therefore, the second probing light of transmitting with
The position for the subject that first distance information is detected is corresponding, so obtain second distance information also with first away from
The position of the subject detected from information is corresponding, and the second distance information obtained in this case can be clearly anti-
Mirror the surface shape of subject.
But if two distances being calculated there are biggish gap, show obtain first distance information and
It obtains in the time between second distance information, biggish variation has occurred in the relative position of video camera and subject.?
In this case, although the second probing light of transmitting is opposite with the position for the subject that first distance information is detected
It answers, but according to the different surface shape for surely clearly reflecting subject of the probing light of reflection.Subject with
The relative position of video camera is possible to reflecting the first probing light and occurring in the period reflected between the second probing light
Biggish variation.
For example, the distance between video camera and subject increase sharply in above-mentioned shooting process, subject
Body is more and more remoter apart from video camera, emits the first probing light by video camera, reflects on subject surface, propagates
After returning video camera, calculating the distance between first distance information representation video camera and subject of acquisition is M.According to this
Distance M emits the second probing light, since the distance between subject and video camera are continuously increased, so that subject
It is farther apart from video camera when body reflecting the second probing light than the first probing light of reflection.This visits second be propagated back to
There is biggish decaying in the energy for surveying light, the second probing light of the reflection that video camera receives be possible to in environment light
The energy of infrared light is essentially identical.It can not at this point, calculating the second distance information obtained according to the second probing light of reflection
The accurately surface shape of reaction subject, so that the stereopsis finally obtained is smudgy clear.
Therefore, when first distance information and second distance information gap are larger, scheme provided by the present application is redefined
The range information of the subject, using new range information as first distance information, so that subject exists
It reflects between the second probing light of the first probing light and reflection, the relative position between video camera does not have excessive variation, from
And guarantee that the stereopsis finally obtained is clear.
The method based on the above embodiment, a referring to fig. 4, in above-mentioned steps 11, according to receiving by being taken
The first probing light of part of object reflection determines the first distance information of subject, specifically includes:
Step 16: the first probing light of part reflected by the subject, root are received by part photosensitive element
The first distance information of the subject is determined according to the first probing light of part received；
Above-mentioned steps 13, according to the part of reflection second probing light determine the second of the subject away from
From information, specifically include:
Step 17: being received by least partly photosensitive element and light is detected by the part second that the subject reflects
Line determines the second distance information of the subject according to second probing light received.
In the above scheme, the first probing light received is mainly used for primarily determining subject and video camera
Between relative position, then to emit and received second probing light can clearly reflect the table of subject
Face shape.The first probing light for receiving reflection in this programme by part photosensitive element, i.e., only open the photosensitive member of part CCD
Part receives above-mentioned first probing light of reflection, the energy consumed when so as to further decrease shooting.And in subsequent step
In, the second probing light of reflection is received by least partly photosensitive element, preferably, is received by whole photosensitive elements anti-
The second probing light penetrated, i.e. unlatching whole CCD photosensitive element, can receive as much as possible by subject surface reflection
Probing light improve the stereopsis subsequently generated to capture subject surface shape details as much as possible
Resolution ratio, optimize shooting effect.
Specifically, as shown in Figure 4 b, the CCD photosensitive element arranged with 5 row, 5 column array is shown in figure, when reception reflection
When the first probing light, multiple photosensitive elements in unlatching figure shown in shade are preferably opened when receiving the first probing light
The photosensitive element positioned at corner and center is opened, on the basis of reducing energy consumption, comprehensively obtains subject corner as far as possible
With the position at center, to substantially determine the relative distance of subject and video camera.It is with situation shown in scheming
Example, opens 5 photosensitive elements, can calculate 5 distance values according to this 5 photosensitive elements.Preferably, to calculated 5
Distance value calculates average value, will calculate the average value obtained and is determined as the distance between video camera and subject, generation the
One range information.
Then, when receiving the second probing light of reflection, as illustrated in fig. 4 c, whole photosensitive elements are opened, this unlatching
Photosensitive element also include 5 photosensitive elements opening when receiving the first probing light.It in this case, can be as more as possible
The second probing light for rebounding back of reception, so that the clarity of the subject surface shape of acquisition is improved, so that then
The stereopsis of generation resolution ratio with higher and preferably shooting effect.
Technical solution provided by the present application receives reflected by subject first by small number of photosensitive element
Probing light receives the second probing light reflected by subject by greater number of photosensitive element.Wherein, by connecing
The first probing light received can determine that the relative position between subject and video camera, and can reduce in shooting process
Energy consumption.The surface of more subjects can be obtained as far as possible by receiving the second probing light by more photosensitive element
Shape details make the stereopsis subsequently generated resolution ratio with higher, guarantee preferably shooting effect.
The scheme based on the above embodiment, the intensity value of the second probing light of the determination and described is taken
The distance between device of object and shooting stereo image is positively correlated.
If the distance between device of subject and shooting stereo image is farther out, since probing light is being propagated
There is energy loss in the process, shooting body surface can be touched and the energy for being reflected back the probing light of above-mentioned apparatus is lower,
It is easy to cause the unsharp situation of shooting picture.Therefore, the intensity value of the second probing light is directly proportional to above-mentioned distance value, right
In apart from farther away subject, emissive porwer is worth biggish second probing light, for the subject being closer
Body can send lesser second probing light of intensity value, to guarantee probing light arrival subject and be reflected back
Energy with higher when the device of shooting stereo image guarantees that the device of shooting stereo image can be by the second detection of reflection
Light is distinguished from environment light, and then improves image-capturing resolution.
