It is configured with field.Such as applying when the field of driving, this target size is the width of road, and this predetermined threshold value is vehicle body
Width.When judging this target size more than predetermined threshold value, then terminal performs step S208；When judge this target size less than or
When person is equal to predetermined threshold value, then terminal performs step S209.
Step S208, when the target size of this object under test is more than this predetermined threshold value, shows the first cue.
Such as, when terminal judges this target size more than predetermined threshold value, then terminal sends the first prompt tone, and terminal is also
The first information can be shown on screen.
Step S209, when the target size of this object under test is less than or equal to this predetermined threshold value, shows the second prompting letter
Number.
Such as, when terminal judges this target size less than or equal to predetermined threshold value, then terminal sends the second prompting
Sound, terminal can also show the second information on screen.
The processing method of the information data of the present embodiment, on the basis of embodiment one, by obtaining object under test in sense
Correspondingly-sized on tabula rasa, obtains target size according to this size, improves accuracy；The most also by target size and default threshold
Value compares, and provides a user with different cues according to comparative result, not only brings conveniently to user, also improve
The treatment effeciency of terminal, further increases the motility of terminal in addition.
Refer to the flow chart of the processing method of the information data that Fig. 3, Fig. 3 provide for the embodiment of the present invention three.
The present embodiment is described in detail as a example by target size is as width, the process of the information data of this preferred embodiment
Method, including:
Step S301, carries out taking pictures for the first time, and obtains the pixel of object under test and the focal length of photographic head, obtain the first picture
Element and the first focal length.
Such as, objects in front is taken pictures for focus by user with crossing, obtains preview picture；Terminal obtains crossing afterwards
Pixel P1 and the focal length L1 of current photographic head.
Step S302, when the distance detected between object under test changes, obtains the distance of movement.
Such as, automobile move forward a segment distance time, terminal detects its distance moved.When such as automobile moves forward,
The polarity of distance is just, when automobile is moved rearwards by, the polarity of distance is negative.
Step S303, carries out second time and takes pictures, and obtain the pixel of object under test and the focal length of photographic head, obtain the second picture
Element and the second focal length.
Such as, objects in front is taken pictures for focus by user again with crossing, obtains preview picture；Terminal obtains afterwards
Pixel P2 at crossing and the focal length L2 of photographic head.
Step S304, obtains this object under test the first imaging chi on the photographic plate of this photographic head according to this first pixel
Very little.
Such as, between the resolution of preview image when terminal can obtain the resolution of photographic plate and take pictures for the first time
Ratio beta, calculates the pixel on photographic plate according to this ratio beta and the first pixel P1；Terminal also obtains preview when taking pictures for the first time
The resolution K of image, is calculated the crossing the first one-tenth image width on photographic plate by the pixel of photographic plate divided by this resolution K
Degree N1.
Specifically, N1 is calculated by formula 2:
N1=β * P1/K formula 2
Step S305, obtains this object under test the second imaging chi on the photographic plate of this photographic head according to this second pixel
Very little.

Element, divided by above-mentioned resolution K, is calculated the crossing the second imaging width N2 on photographic plate.Owing to resolution is usually fixed
, the resolution of image when therefore second time is taken pictures is equal to the resolution of image when taking pictures for the first time.
Specifically, N2 is calculated by formula 3:
N2=β * P2/K formula 3
Step S306, according to this displacement, this first imaging width, this first focal length, this second imaging width, this
Two focal lengths obtain the width of this object under test.
During owing to taking pictures for the first time, the ratio of the first imaging width N1 and the first focal length L1 is equal to width H and the road at crossing
Distance M1 ratio between mouth and terminal, as shown in Equation 4:
N1/L1=H/M1；Formula 4
When taking pictures due to second time, the ratio of the second imaging width N2 and the second focal length L2 is equal to width H and the road at crossing
Distance M1 ± m ratio between mouth and terminal, as shown in Equation 5:
N2/L2=H/ (M1 ± m)；Formula 5
Obtain formula 6,7 in conjunction with formula 2 to formula 5, when automobile move forward carry out second time take pictures time, the width at this crossing
Degree H1 is concrete as shown in Equation 6:
H1=m* (β/K) * (P1*P2/ (L1*P2-L2*P1))；Formula 6
When car reversed carries out taking pictures for the second time, the width H2 at this crossing is concrete the most as shown in Equation 7:
H2=m* (β/K) * (P1*P2/ (L1*P2+L2*P1))；Formula 7
Wherein H1 or H2 is the width at this crossing, and m is this displacement, and β is this ratio, and P1 is this first pixel, P2
For this second pixel, L1 be this first focal length, L2 be this second focal length, K is this resolution.
Step S307, it is judged that whether the width of this object under test is more than predetermined threshold value.
Such as, the width at the crossing that step S306 obtains is compared by terminal with predetermined threshold value, and this predetermined threshold value is vehicle body
Width.When the width judging this crossing is more than body width, then terminal performs step S308；When the width judging crossing is less than
Or during equal to body width, then terminal performs step S309.
Step S308, when the width of this object under test is more than this predetermined threshold value, shows the first cue.
Such as, when terminal judges the width at this crossing more than body width, then terminal sends the prompting of " can pass through "
Sound, terminal can also show " continuing with moving ahead " on screen.
Step S309, when the width of this object under test is less than or equal to this predetermined threshold value, shows the second cue.
Such as, when the width judging crossing is less than or equal to body width, then terminal sends carrying of " can not passing through "
Showing sound, terminal can also show " junction ahead is narrower, please detour " on screen.
The processing method of the information data of the present embodiment, by carrying out taking pictures of different distance, obtains the width of object under test
Degree；And the width of acquisition is compared with predetermined threshold value, if this width is more than predetermined threshold value, then show the first prompting letter
Number, if this width is less than or equal to predetermined threshold value, then shows the second cue so that user uses convenient, carry
The high motility of Consumer's Experience and terminal.
