Description
Technical field
The present invention relates to the communications field, and in particular to the network coverage of the indoor and outdoor of the communications field based on picture or video
Can the anti-false survey method and device of test.
Background technology
In communication technical field, when carrying out network covering property test, it is desirable to beat test point position in Zou Biance, and one
Tester original place in test process is static, original place is turn-taked, walks part way etc. a bit beats test point position, causes indoor and outdoor to cover
It is inaccurate to test the network covering property index, signaling and time of collection, great difficulty is caused to network coverage optimization.
The content of the invention
The problem to be solved in the present invention is to provide a kind of based on the anti-false survey side of the network covering property of picture or video test
Method, avoid network covering property tester original place in test process is static, original place is turn-taked, walks part way etc. from getting test ready
False survey behavior, improve the test effect of network covering property.
In order to solve the above technical problems, the scheme that the present invention uses is：The network covering property based on picture or video
Anti- false survey method is tested, is comprised the following steps：
(1) comparison threshold value C and contrast sequence are set；
(2) photo or video shot during network covering property tester test is obtained；Wherein, if what is obtained is to regard
Frequently, video is changed into picture；
(3) the reduced value R of picture in the step (2) is obtained；
(4) the reduced value R and the comparison threshold value C set in the step (1) size in the step (3) are judged；If R
>=C, non-false survey result is exported, if R ＜ C, vacation is exported and surveys result.
What comparison threshold value was defined as：Acquired picture is named as Y1、Y2、Y3……Yn, picture pixels are right
Than the consistent degree of each picture pixels, wherein reduced value R=(Y1With Y2Differ number/Y of addressed pixel1Or Y2Number of pixels)
× 100%；In the inventive solutions, it is Y that we, which simply compare one group of picture,1With Y2The comparison threshold value drawn, when
So, we can also adjust different contrast sequences so that section span picture group a little greatly (such as contrast sequence selection 5, then it is
Y1With Y6) contrasted, and then comparison threshold value is drawn, the specific selection for contrasting sequence can be according to the movement velocity of tester
To determine, if speed is fast, then contrast sequence just selects smaller, if speed is slow, then contrasts sequence and just selects greatly；Pass through net
Real-time or interval collection photo or video when network covering performance tester tests, to judge that network covering property personnel are surveying
Walking manner and method during examination, avoid network covering property tester original place in test process is static, original place is turn-taked,
The false survey behavior that part way etc. gets test ready is walked, improves the test effect of network covering property.
Preferably, in the step (1), the pixel and resolution ratio for gathering picture are set；If what need to be shot is video,
The frame of the pixel for gathering video, resolution ratio and video recording is then set.
Preferably, it is used to shoot picture in the step (2) or the camera of video must the unobstructed carrying of forward vertical.
This mode sets the environment that could really reflect network covering property tester course in test,
The picture or video of shooting carry out contrast could more objective reality reflection tester walking manner and method；This side
Formula shooting it also avoid shooting the scenes without significant change such as ceiling.
Preferably, the picture of acquisition or the mode of video and frequency, it is lasting real-time collection in the step (2)
, or interval time is set, according to interval time, gap collection.
Preferably, in the step (2), if obtain be video, configure video extraction frame, by Video Quality Metric into
Picture, the acquisition frame of video is X1、X2、X3、……、XnIf it is 1 to set extraction frame, the picture X extracted1、X2、X3、……、Xn
And Xn+1；If it is 2 to set extraction frame, the picture X extracted1、X3、X5、……、XnAnd Xn+2。
The mode not limited to this of above-mentioned conversion picture, other extraction frames can also be arranged to, it is therefore an objective to by the video of acquisition
It is converted into picture.
Preferably, picture will be obtained or after the picture pixels of video extraction, in the step (3), contrast is each
The consistent degree of picture pixels, and configure contrast sequence or comparison threshold value；
Configure aligned sequences：As acquired picture is named as Y1、Y2、Y3、……、Yn, it is 1 to set contrast sequence, then schemes
Piece Y1And Y2、Y2And Y3、……、YnAnd Yn+1；
Configure comparison threshold value：Comparison threshold value scope is 1%~100%, when it is 1 to contrast sequence, if setting comparison threshold value C
For 30%, reduced value R=(Y1With Y2Differ number/Y of addressed pixel1Or Y2Number of pixels) × 100%.
As previously described, the mode not limited to this of above-mentioned aligned sequences, can be set according to the speed of service of tester
Into other, comparison threshold value is also in this way, different comparison threshold values is configured according to environmental requirement, such as surrounding enviroment similarity-rough set
Greatly, comparison threshold value can be set smaller, as surrounding enviroment differ greatly, comparison threshold value can be set larger.
The invention solves another problem be to provide it is a kind of anti-based on the test of the network covering property of picture or video
Device is surveyed in vacation.
This is included based on the anti-false device of surveying of the network covering property of picture or video test：
Picture or video capture module, shoot picture when being tested for network covering property tester or regard
Frequently；
Obtain picture or video module, shoot for obtaining network covering property tester when being tested picture or
Video；
Picture processing analysis module, by the Video Quality Metric received in the acquisition picture or video module into picture, then
The picture of the conversion or the picture for obtaining the acquisition picture or video module are analyzed, judge the network coverage
Performance personnel walking manner and method in test process, export judged result.
If what acquisition picture or video module obtained is picture, then picture processing analysis module then omits conversion picture step
Suddenly.
Preferably, the picture processing analysis module is additionally operable to, and for the video of acquisition, the acquisition frame of video is X1、X2、
X3……XnIf it is 1 to set extraction frame, the picture X extracted1、X2、X3……、XnAnd Xn+1；If it is 2 to set extraction frame, carry
The picture X taken1、X3、X5……、XnAnd Xn+2。
Preferably, the picture processing analysis module is additionally operable to, and is received request, is parsed the configuration aligned sequences of picture and match somebody with somebody
Put comparison threshold value.
