Detailed description of the invention
Being described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar implication from start to finish.The embodiment described below with reference to accompanying drawing is illustrative of, and is only used for explaining the present invention, and is not considered as limiting the invention.
As it is shown in figure 1, the invention provides a kind of abnormal track-detecting method divided based on region, including: the GPS historical trajectory data of Mobile solution being classified, extracts feature, the trajectory map that track region carries out region division processes;Then the track data after carrying out region division is carried out territory element extension, make up the sample frequency of GPS track data and move the track characteristic extraction error that object translational speed diversity causes;Track data to be detected is carried out region division and from normal trace sequence library, extracts the track data set TR that initiation region unit with it is identical with termination area unit;Travel through the territory element track of trajectory map to be detected, obtain each territory element supporting rate in normal trace set, and compared with threshold value, obtain abnormal area unit set A (gi);Judge the abnormal conditions of track to be detected, according to the track in set TR and set A (gi) length | A (gi) | relation judges the abnormal conditions of track to be detected, carries out the track abnormality detection that region divides again.Specifically comprise the following steps that
S1: the GPS historical trajectory data of mobile subscriber is classified, extracts normal trace data track characteristic, the track extracting feature carries out region and divides mapping process.
S2: the track after step S1 is processed carries out track data territory element extension, the track characteristic that the diversity of the sample frequency and mobile object velocity of revising GPS track data causes extracts error, obtains algorithm data input.
S3: track data to be detected carried out region division process and extracts the track data that initiation region unit is identical with termination area unit with it from normal trace sequence library, obtaining normal trace set TR.
S4: travel through the cell track obtained after track regions to be detected divides, obtain each cell supporting rate in normal trace set, and compared with threshold value, obtain abnormal area unit set A (gi);
S5: judge the abnormal conditions of track to be detected, according to set TR and set A (gi) length relation judge the abnormal conditions of track to be detected.
S6: carry out according to the concrete condition of GPS track data that region is subdivided and abnormality detection.
The present invention is that the GPS track data to mobile terminal collection carry out abnormal detection, is possible not only to the abnormal conditions of whole track are differentiated, and may indicate that abnormal sub-trajectory occurs track;And according to the concrete condition of track, track can being carried out the abnormality detection that region is subdivided, due to the abnormality detection that region is subdivided, efficiency of algorithm obtains a degree of raising, and the detection time is shorter, in hgher efficiency.There is using value in practice more.
The sample of the present invention is the historical track of mobile object, and GPS track historical data is classified, and extracts the longitude of track, latitude and timestamp, pi(longitude, latitude, time), piRepresenting the GPS raw data points of motion track, it is to comprise longitude, latitude and three basic information of timestamp.Then track collection area scope being divided into the territory element specifying size, the scope of each territory element being scanned for, if there is tracing point piSo this territory element is the ingredient of the track after track regions divides, without tracing point piThen this cell is not then the ingredient of track;Track data is carried out GPS track data after region division processes and has become the set Tr=(g being made up of territory elementi)。
Territory element lattice after dividing have been carried out extension process by the present invention, reason due to the sample frequency of gps data, even the same track, region may obtain different territory element set after dividing, carry out cell detection time, may be abnormal track by wherein normal track detection, cause testing result and practical situation not to meet.In order to solve this situation, it is necessary to being extended for track after region is divided, territory element adjacent thereto is also concluded in the unit set of track regions, timestamp is the same.
The abnormal track-detecting method that the present invention divides based on region, extract the normal trace set of identical initiation region unit and termination area unit: the track to be detected according to input, region obtains initiation region unit and the termination area unit of this track after dividing, then from normal trace sequence library to the identical track group of beginning and end, these tracks group form track set TR.Then normal trace set TR={tr is obtained1,tr2,tr3,...,tri, wherein i is number | TR |, the TR of track in TR and track tr to be detectedcheck={ g1,g2,g3,...,giAs the input of detection algorithm.
The abnormal track-detecting method that the present invention divides based on region, track abnormality detection stage etch:
S41: to trcheck={ g1,g2,g3,...,giCarry out abnormal conditions detection time, travel through trcheckEach compositing area cell, with normal trace set TR={tr1,tr2,tr3,...,triIn track tri={ gi1,gi2,gi3,...,gijTerritory element compare, travel through trcheckIn each territory element, TR={tr1,tr2,tr3,...,triWhether there is track triWith trcheckThere is identical territory element.If there is such track tri, then by track triDeposit into track set Inc (TR, trcheck) in, wherein Namely the quantity of each later territory element of trajectory map to be detected track identical with track regions unit in normal trace set is calculated.Track set Inc (TR, trcheck) weigh track tr to be detectedcheckTerritory element g with normal trace set TR (identical initiation region unit and termination area unit)iSituation about overlapping.
S42: for each compositing area unit g of track to be detectediThere are corresponding set Inc (TR, a trcheck), calculate Inc (TR, the tr of each territory elementcheck) tracking quantity | Inc (TR, trcheck) | the proportion accounted in normal trace set TR, define a threshold θ (0≤θ≤1) according to practical situation simultaneously and judge the effect that track is abnormal of proportion.Proportion functionJust can determine whether whether this territory element is track tr according to proportion functioncheckIn normal trace point, as Sup (Tr, trcheck) < this territory element is put into abnormal area unit set A (g by θi) in, and as Sup (Tr, trcheckThis territory element is deposited into normal region unit set N (g by) >=θi) in, this territory element is the normal segments of track.Namely when the territory element of track obtain the support of more track time be considered as the normal part of track, but the less part obtaining normal trace support is considered as unusual part, after whole piece track has all detected, it is possible to obtain abnormal area unit set A (gi) and normal region unit set N (gi), wherein i is A (gi) in the number of territory element set | A (gi)|。
The abnormal track-detecting method that the present invention divides based on region, it is judged that the abnormal conditions method of track to be detected is:
S51: obtain abnormal area unit set A (gi) after, the detection of the abnormal conditions of track is converted to the abnormal area element number problem to the territory element forming path, when the quantity of abnormal area unit | A (gi) | more than one preset valueTime,Value be usually track to be detected composition territory element quantity 1/2, i.e. abnormal area unit set A (gi) number of elements | A (gi) | time more, this track is abnormal;Otherwise, this track is normal.
S52: exceptional value determining type is as follows:Wherein α is constants, and k is the constant relevant to the meansigma methods of the territory element number of the set each track of TR.The judgement of track abnormal conditions is not only needed to detect the number of abnormal area unit | A (gi) |, also have the average length of the track of normal trace set, so more conform to the situation of reality, it is to avoid erroneous judgement.Average length according further to the track of normal trace set can also avoid following a kind of special situation, and the accuracy of the detection being is higher.
The present invention further optimizes detection algorithm, when GPS track carries out region division mapping, the length of side of territory element is changeless, also just says that the size of territory element is constant, the type that the size of territory element is according to gps data determines, very big deviation will not occur the result of detection.But when territory element is less, the territory element opposed area unit larger amt of composition track wants many, and the place of territory element is comprehended and causes more energy consumption and time loss by detection algorithm, can be also higher to the performance requirement of system.The present invention proposes a kind of based on the subdivided detection method in region according to the practical situation of track, reduces the energy consumption of detection and reduces the time of detection.The basic thought of method is first by bigger territory element, track to be detected, so can just can detecting track obvious for some off-notes when territory element is bigger, it is made without the process that territory element is less, the territory element of the track of composition increases, the amount of calculation that the algorithm of abnormality detection needs increases, and the requirement of time is also increased by the increase of amount of calculation accordingly, if online detection, then will result in ageing bad effect.The subdivided abnormal track detection algorithm in region that the present invention adopts will reduce the power consumption of system to a certain extent and make the ageing of detection be improved to some extent.
nullThe data volume dropping on same territory element owing to dropping on the tracing point in identical strip path curve is different,Sample frequency is fixing,Speed is then various,The distance different (distance=speed/frequency) that mobile object moves can be caused,Namely the distance between object trajectory data point is moved different,So the present invention uses the territory element track to carrying out after the division of region to be extended,First the traversal all of data point of track,Obtain the trajectory map sequence at the cell of area planar map,Then in order to reduce error,The adjacent area unit of the territory element that tracing point is fallen into (include itself one have nine) is also required to give a basic numerical value (being denoted as the territory element of 1 in Fig. 2),The track preventing path identical produces bigger diversity,Testing result is made to there is bigger deviation with practical situation,Track abnormal conditions are judged by accident.Fig. 2 grey area unit is the territory element that track data point falls into, and its value is the quantitative value of the data point falling into this territory element, uses g in figureiRepresent;The value of its neighbours' territory element is 1;The value of other territory elements is 0.Track can be expressed as tr=(g1,g2,...,g11) wherein also include neighbours' territory element of territory element sequence.
Fig. 3 is the flow chart of invention algorithm, first the input of algorithm is the historical trajectory data of mobile object and track data to be detected, two class data carries out region division respectively and extension obtains the territory element sequence tr of historical track territory element sequence library TR and track to be detectedcheck={ g1,g2,...,gn};Then by TR and trcheck={ g1,g2,...,gnCalculate trcheckIn the proportion function Sup value of each territory element, it is judged that Sup and the magnitude relationship of threshold value, if the Sup value of territory element is less than threshold value, then corresponding territory element is deposited into abnormal area unit set A (gi) in until travel through whole trcheck;Then A (g is comparedi) the average area unit number of track, to judge that whether track to be detected abnormal, and may indicate that abnormal sub-trajectory occurs in the territory element number gathered and TR;Concrete condition finally according to track to be detected decides whether track is carried out the track abnormality detection that region divides again.
Although an embodiment of the present invention has been shown and described, it will be understood by those skilled in the art that: these embodiments can being carried out multiple change, amendment, replacement and modification when without departing from principles of the invention and objective, the scope of the present invention is limited by claim and equivalent thereof.
