Height, development cycle are long.Therefore in order to reduce the difficulty for improving picture recognition accuracy rate, it is different from conventional method, this programme is from improvement
The angle of picture quality to be identified improves picture recognition accuracy rate and will not take at once that is, after the shooting for completing picture
Picture as picture to be identified, but using the picture taken as picture to be determined, due to picture to be determined embody it is pre-
If the corresponding parameter information of parameter included by photographing request, therefore according to the available parameter information of picture to be determined, parameter letter
Breath meets the picture to be determined of default photographing request, it is believed that its picture quality is higher.Therefore alignment parameters information and default bat
Take the photograph requirement, however, it is determined that go out the corresponding parameter information of target component in parameter and be unsatisfactory for default photographing request, then according to comparison result
The first adjustment operation instruction is generated, the first adjustment operation instruction can indicate that the terminal of user's adjustment shooting picture to be determined is set
Standby, to re-shoot picture to be determined, the parameter information until shooting obtained picture to be determined meets default photographing request, will
Picture to be determined is as picture to be identified.In this way, the picture to be identified got is all that parameter information meets default photographing request
Picture, picture quality is higher, and picture to be identified higher to picture quality identifies that the accuracy rate of picture recognition can also mention
It is high.Compared with traditional approach, this programme only needs user to adjust terminal device according to the first adjustment operation instruction, and should not
User is asked to have higher technical capability, it is simple to operate, it can quickly obtain the higher picture to be identified of picture quality.
It is understood that presetting photographing request under different situations since default photographing request is there may be a variety of situations
Included parameter is different, correspondingly, the specific implementation of S101 is different.Next, will be under different situations
The specific implementation of S101 is introduced.
If default photographing request be the pitch angle of terminal device within a preset range, preset parameter included by photographing request
For the pitch angle of terminal device, parameter information is pitch angle angle value.The pitch angle of terminal device may include within a preset range
A variety of situations, a kind of it may is that terminal device pitch angle is 0, i.e. terminal device obtains picture Shi Bucun to be determined in shooting
It overlooks or is looking up, it is vertical with horizontal direction.
In this case, the specific implementation of S101 is to be obtained according to the gyroscope testing result built in terminal device
Pitch angle angle value when the terminal device being taken to shoot the picture to be determined.
Gyroscope built in terminal device can recorde the pitch angle angle value that terminal device shoots picture to be determined, in this way,
The pitch angle angle value of the available gyroscope record of terminal device.Under normal circumstances, the pitch angle angle value that gyroscope is recorded is
Terminal device pitch angle angle value is 0 or is not 0.
Correspondingly, after getting pitch angle angle value, however, it is determined that going out elevation angle angle value is not 0, i.e., terminal device, which exists, overlooks
Or look up, at this point, generating the according to the comparison result of the parameter information of target component (pitch angle) and the default photographing request
One adjustment operation instruction is as shown in Figure 2.Wherein, if the angle of depression is not 0, it is determined that terminal device, which exists, to be overlooked, and the first adjustment is generated
Operation instruction is as shown in the "+" of logos in Fig. 2, to indicate that user adjusts terminal device towards the direction for reducing the angle of depression；If
The elevation angle is not 0, it is determined that terminal device, which exists, to be looked up, and the "+" institute of the first adjustment operation instruction such as white indicia in Fig. 2 is generated
Show, to indicate that user adjusts terminal device towards the direction for reducing the elevation angle.
If default photographing request is the left and right directions inclination angle of terminal device without departing from preset threshold, photographing request institute is preset
Including parameter be terminal device left and right directions inclination angle, parameter information be left and right directions inclination angle value.In such case
Under, referring to Fig. 3, the specific implementation of S101 are as follows: firstly, carrying out gray proces to the picture to be determined, obtain the first ash
Spend picture；Wherein, as shown at 301 in fig. 3, the second gray scale picture is as shown in 302 in Fig. 3 for picture to be determined.Then, described in acquisition
Meet the first straight line and second straight line of preset condition in first gray level image with horizontal direction angle；It is due to calculative
Left and right directions inclination angle value, therefore, first straight line and second straight line are the straight lines for meeting preset condition with horizontal direction angle.
Then, the vanishing point for calculating the first straight line and second straight line determines the end as shown in 303 in Fig. 3, and according to the vanishing point
End equipment shoots the left and right directions inclination angle value when picture to be determined.
In one possible implementation, determine that left and right directions inclination angle value is specifically as follows determination and goes out according to vanishing point
O'clock to the first gray scale image edge distance, the distance of vanishing point to the first gray scale image edge determines left and right directions inclination angle value
It can reflect left and right directions inclination angle value, distance is bigger, and left and right directions inclination angle value is bigger.Therefore vanishing point is to the first gray scale
The distance of image edge can determine left and right directions inclination angle value.
If the clarity that default photographing request is picture to be determined reaches preset requirement, ginseng included by photographing request is preset
Number is the clarity of picture to be determined, and parameter information is the definition values of picture to be determined.In this case, S101's is specific
Implementation are as follows: gray proces are carried out to the picture to be determined, obtain the second gray scale picture；To the second gray scale picture into
Row frequancy signal anaysis determines the definition values of the picture to be determined according to accounting of the high-frequency signal in frequency-region signal.
It should be noted that in application scenes, it is understood that there may be require division into plurality of pictures for photographic subjects
It is shot, photographic subjects just can completely be shot to situation about coming, for example, photographic subjects are the quotient on multiple shelf
Product, at this time, it may be difficult to by completing shooting by a picture to the commodity on multiple shelf, alternatively, on multiple shelf
Commodity by a picture to complete the picture quality of picture to be determined that shooting obtains lower.Therefore, it is necessary to for shooting mesh
Mark requires division into plurality of pictures and is shot, so that plurality of pictures to be spliced to obtain the corresponding complete graph of photographic subjects
Piece.
In order to guarantee to be spliced plurality of pictures to obtain the corresponding full picture of photographic subjects, the first picture is removed
Outside, other pictures needs shot later are shot referring to previous picture, to know that current image needs to shoot shooting
Which region of target.Therefore, if requiring division into plurality of pictures for photographic subjects and being shot, with and picture to be determined be not
For the first picture of the target to be captured, before executing S101, referring to fig. 4, the method also includes:
S401, practical repeat region of the picture to be captured relative to previous picture is obtained.
In the present embodiment, it in addition to first image to be determined shot for photographic subjects, is obtained in shooting
During other pictures to be determined, need to obtain the practical repeat region for treating shooting picture relative to previous picture, so as to
Determine whether picture to be captured meets splicing and require.Wherein, the picture to be captured is that shooting obtains the picture to be determined
Picture in view-finder in the process.
S402, pass through the comparison practical repeat region and the default repeat region, determine that the picture to be captured is
No satisfaction splicing requires.
S403, it is adjusted if it is not, generating second according to the comparison result of the practical repeat region and the default repeat region
Whole operation instruction.
