Description
Technical field
The present invention relates to field of computer technology, particularly relate to a kind of user terminal, card detection method, device and a game card pause detection method, device.
Background technology
The history of mobile phone games is almost synchronous with mobile phone, early stage mobile phone due to framework simple, configuration is low, so functionally also do not enrich, corresponding mobile phone games are also generally confined to play with words, simple developmental game (such as Tetris, Snake, pushes box).There is not the concept that card pauses in this kind of game.
In Java language, the J2ME of mobile branch occurs, create a collection of early stage smart mobile phone (such as Nokia Saipan etc.), mobile phone games start to be enriched a little, have occurred the game such as a large amount of Simulating management, racing car.Mobile phone games start the concept having had card to pause, all can be the same with end trip on general game downloading web pages, can identify the minimum mobile phone configuration playing this game.In this stage, owing to being subject to the constraint of mobile phone hardware manufacturing capacity, the research that card pauses is very deep, the standard only just defined by cpu frequency and mobile phone EMS memory size, mobile phone lower than this standard goes to play this game, just there will be card, cannot avoid.
Real mobile phone games emerge in multitude still at iOS (Mobile operating system of Apple's exploitation) and Android (Android system, a cell phone system that Google releases) appearance of cell phone system, mobile phone games type is more and more abundanter, index in handset capability also gets more and more, comprise CPU, EMS memory occupation, flow electric quantity consumption, game FPS (Frames Per Second, transmission frame number per second) etc., game card pauses also as an importance of mobile phone games performance index.
At present, the following two schemes of main employing judges that the card of mobile phone games pauses:
Scheme one: hardware based video analysis scheme.
The program is a kind of by game content recording is output into video and the method analyzed video.Specifically comprise step:
In A, the process of playing games, use video frequency collection card to gather mobile phone screen (frequency acquisition 30 times/second) and also save as video file;
B, video file are actually high-frequency successive image frame and are spliced into video file, utilize program code to be extracted by each two field picture in video, preserve into the picture of a series of free order;
Similarity between C, analysis continuous print two pictures, can obtain a similarity sequence curve;
D, a simple mathematical modeling is carried out to this similarity, finally show that game card pauses result and report.
The mathematical model of the program is briefly described as follows:
For similarity sequence, if the double similarity of setting is greater than 99.99%, then being can be regarded as is a card pause point, and once in test, card pause point quantity determines that game card pauses degree.
The card of hardware based video analysis pauses research approach, and the defect of existence clearly, comprising:
1, need extra cost of equipment, and a card test process is more loaded down with trivial details;
2, a card test effect depends on hardware (video frequency collection card) performance, and the game that the picking rate that video frequency collection card is 30 times/second is greater than 30 frames for frame per second exists certain error; Image analysis algorithm also can be larger by picture audio in addition.
Scheme two: the card based on the numerical value of FPS pauses judgement.
Whether this scheme utilizes FPS numerical value to judge to play to block exactly times.FPS refers to the number of times of game in picture refreshing in each in second, and this point is similar to show a film the same, and under normal circumstances, FPS >=30, human eye just cannot perceive card and pause, if when FPS<30, the possible card that just can perceive game pauses.On this basis, in the process of playing hand trip, the FPS numerical value of different time points can be recorded simultaneously, be then depicted as time/FPS curve, the card that can obtain the trip of this hand pauses distribution curve.
In addition, on above-mentioned basis, then modeling analysis is carried out to FPS and the relation of time, then to pause situation from the card numerically analyzing game.Model brief description is as follows:
A. frame per second distribution is upper analyzes: compose a weight, as following table 1 to different frame per second scope accountings respectively:
| Inspection item | Weight | Result |
| [30, ~) frame per second accounting >=90% | 3 | |
| [40, ~) frame per second accounting >=60% | 2 |
| [40, ~) frame per second accounting >=75% | 2 | |
| [45, ~) frame per second accounting >=75% | 2 | |
| [45, ~) frame per second accounting >=90% | 1 | |
| [50, ~) frame per second accounting >=85% | 1 |
(table 1)
B. frame per second fluctuation is upper analyzes: compose a weight to different frame per second Continuous Play respectively, concrete scheme is as following table 2:
| Frame per second from [30, ~) reduce continuously [20, ~) frequency be (~, 10] beat/min | 2 | |
| Frame per second from [30, ~) reduce continuously [20, ~) frequency be (~, 3] beat/min | 1 | |
| Frame per second from [30, ~) reduce continuously [and 15,20) frequency be (~, 15] beat/min | 2 | |
| Frame per second from [30, ~) reduce continuously [and 15,20) frequency be (~, 10] beat/min | 2 | |
| Frame per second from [30, ~) reduce continuously [and 15,20) frequency be (~, 3] beat/min | 1 |
(table 2)
Finally, according to A, B two model criteria weights, card score value and a grading can be obtained respectively, then get minimum grading, be the grading of this game.Concrete marking mode is as follows:
For the form clause x in above-mentioned A, B two, weight is respectively a, and what pass through is 1, not by for 0, to ignore be that 1, two kinds of analysis mode scores are respectively Ya, Yb, final score is Z, and formula is as follows:
Y＝(x1*a1+x2*a2+…+xn*an)/(a1+a2+…+an)
Z＝min(Ya，Yb)
By final score Z, the rating scale with reference to definition can show that game card pauses and be rated S, A, B, C.Standard sees the following form 3:
| Rank | Describe | Score |
| S | Very smooth | 0.9+ |
| A | Substantially smooth | 0.7～0.9 |
| B | Some card | 0.4～0.7 |
| C | Serious card pauses | 0.4- |
(table 3)
Compare hardware based video analysis scheme one, adopt the decision scheme of pausing of the card of numerical value of FPS to reduce costs.In addition, use FPS numerical value to have certain science as a card decision procedure of pausing, and be that whether the card that can determine game pauses from the perception of human eye for picture really.But can not the card of real fine-grained reaction game to pause problem, a game FPS can be stabilized in 50 ~ 60 frames, even if like this, player also may be allowed to experience Ka Dun and not well sensation.
The card of FPS pauses research can only the going research and judge card of coarseness, this is because FPS account form causes.The calculating of FPS is not real-time, but sampled point interior between regulation, the FPS of calculating is actually the mean value before two ability 2.Detailed process following (supposing that sampled point was 1 second):
Sampled point 1: system always refreshes frame number f1
Sampled point 2: system always refreshes frame number f2
So the frame per second of sampled point 2 is: (f2-f1)/1 (frame number/second)
It is formal because FPS is a mean value concept, in what it numerically represented is in this second real time frame rate level and smooth after value, it has very large relation at not numerical value in the same time and sampling time interval, and interval is larger, FPS time curve is more level and smooth, and more difficult foundation FPS detects card release and pauses.In theory, if the FPS sampling time is reduced to minimum, real FPS value can be obtained, but uncertain due to time of system refresh picture, so sampling time minimum FPS numerical value is without any meaning.
Based on above explanation, study card only when the sampling time is suitable based on FPS numerical value, just have certain card to pause Research Significance, the research and analysis and the card that can only do the sampling time (such as 1 second) such coarseness pauses.This is that FPS is for card the limitation analyzed and shortcoming place.
In addition, Mathematical Models process and the dissimilar game relation of the program are very big, different game needs a set of different model parameter, and the determination of this parameter carrys out experimental check by a large amount of standard game, there is very large subjective factor in the determination of parameter values, the card going inspection one to play not sending out objective science completely pauses.
To sum up, the card based on the numerical value of FPS pause the defect that judges have two: one be FPS data due to its concept reason, be used for doing a card careful not and accurate problem of research existence itself; Two is that Selecting parameter in FPS mathematical model is very subjective, can not the card of reflection game of objective science to pause situation.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, Fig. 1 is that card that first embodiment of the invention provides pauses the schematic flow sheet of detection method.Specifically comprise the steps:
S101, when on the terminal screen of Real-time Obtaining, the rgb value of some pixels changes, record current time stamp, thus obtain a timestamp sequence;
In embodiments of the present invention, described terminal can be smart mobile phone (as the mobile phone of Android system, the i Phone of IOS system or the mobile phone of WP system) or panel computer etc.Described terminal can be used for running various application program, as game or various application etc.
When adopting described terminal operating application program, the situation of change coming on monitoring screen by selecting N number of (such as, N can equal 4) control point on a terminal screen.In the present embodiment, frame buffering (FrameBuffer) device file by monitoring Linux carrys out the rgb value of this N number of control point on Real-time Obtaining terminal screen.
Below in conjunction with Fig. 2, how detailed description is by the change on the next real-time monitoring screen of the framebuffer device file of monitoring Linux.As shown in Figure 2, step S101 comprises further:
S1011, reading frame buffer zone device file;
Generally, user terminal image information is shown on screen often by FrameBuffer.The device file that frame buffer zone equipment is corresponding is /dev/graphics/fb0, and file reading/dev/graphics/fb0 is equivalent to reading screen buffer zone.Such as can, by the copy content of current screen in a file, cp tmp>/dev/graphics/fb0 be ordered then to be presented on screen by graphic file tmp with cp/dev/graphics/fb0tmp order.
S1012, by map operation, described frame buffer zone device file is mapped in internal memory;
Because Linux is operated in protected mode, each application program has oneself virtual address space, directly can not access physical address buffer in the application.For this reason, Linux provides mmap function in file operation file_operations structure, can by the content map of file to user's space.For framebuffer device, then by map operation, can by the physical address map of screen buffer in one section of virtual address of user's space, user just by read-write this section of virtual address access screen buffer zone, screen can have been drawn afterwards.In fact, the application program of framebuffer device is used all to carry out display graphics by map operation.
S1013, the changes in coordinates of some screen pixels points monitored as required, to the side-play amount in internal memory, read out the rgb value of corresponding coordinate point at a certain time interval;
After by mmap to memory-mapped, then the changes in coordinates passing through the screen pixels point monitored as required, to the side-play amount in internal memory, just can take out the on-screen data of corresponding coordinate point from internal memory, and here, we only need the rgb value reading corresponding coordinate point.In the present embodiment, the described time interval is 2 milliseconds.
The rgb value of the corresponding coordinate point that S1014, the rgb value of corresponding coordinate point read by current time and a upper moment read contrasts, when the rgb value of any one coordinate points changes, record current time stamp, thus obtain the timestamp sequence of a test period.
Wherein, what each timestamp in described timestamp sequence identified is in test process, the time that screen changes at every turn.
Visible, the present embodiment realizes monitoring screen change by the FrameBuffer device file monitoring Linux, can in millisecond rank (such as, the screen change of reading control point 2ms), compare level operation second carrying out mobile phone screen sectional drawing, performance improves very large, and the research that card pauses is only just more convincing when time granularity is smaller.
S102, described timestamp sequence converted to a card time-delayed sequence, the described card each card paused in the time-delayed sequence delay data that pauses is the difference of adjacent two timestamps in described timestamp sequence;
In this step, need the raw data to step S101 collects to process, specifically timestamp sequence transformation is become a card time-delayed sequence, concrete processing mode is as follows:
Suppose that timestamp sequence T sequence is: T=[t0, t1, t2 ... .t (n-1), tn], so a card time-delayed sequence D is: D=[t1-t0, t2-t1 ... tn-t (n-1)].
Can find out, a card time-delayed sequence D is the spacing of adjacent time stamp time in timestamp sequence T.Be understood that, what block each data representation in a time-delayed sequence D is the time interval that screen-picture remains unchanged, and is a card delay time.Wherein, Fig. 3 shows a card time-delayed sequence.
S103, the time-delayed sequence that to pause based on described card calculate and obtain a card information, the described card information of pausing comprises following one or more: described card pause the variance of time-delayed sequence, described card pause the card that is greater than predetermined threshold value than the mean value of a card time-delayed sequence in time-delayed sequence pause delay data quantity, meet time delay accounting function and be more than or equal to the minimum value of 95% and the difference of the mean value of a card time-delayed sequence, described time delay accounting function is the ratio data being less than or equal to described minimum value in a described time-delayed sequence.
After the data processing of step S102, obtaining card time-delayed sequence, by carrying out mathematical modeling to it, to pause situation to calculate card release.In the present embodiment, carry out analyzing card to pause situation mainly through calculating following three indexs:
Index 1: delay time variance
From Fig. 3 curve, significantly can see a stable horizontal line, this root line is the average line of a card time delay.Card in calculation procedure 2 the pause mean value average of delay data, the average of all cards in time-delayed sequence D that pause is that screen card pauses averaging time of time delay at numerical response, and this averaging time, as card averaging time, is a basic data of a card analysis.
The variance of a card time-delayed sequence D can reflect the fluctuation situation of data in this sequence.The pause fluctuation situation of delay time of screen card can be paused severe degree from reflecting on the one hand the card of application program (such as, playing); If the screen change of a game is for a moment fast for a moment slow, can be easy to present the sensation that card release pauses to player, otherwise if the change of game screen is all stabilized in average value ranges, so game will give the very smooth sensation smoothly of player.The pause variance variance of time-delayed sequence D of computer card can reflect that the card of game pauses situation, and variance is larger, illustrates that game time delay fluctuation is larger, and the card Shaoxing opera that pauses is strong.
The computing formula of variance is as follows:
Suppose the mean value M:M=(x1+x2+x3+ of a card time-delayed sequence D ... + xn) (n represents this group data amount check to/n, x1, x2, x3 ... xn represents the concrete numerical value of these group data)
So variance S:S
2=< (M-x1)
2+ (M-x2)
2+ (M-x3)
2+ ... + (M-xn)
2> ╱ n
Index 2: doubtful card pause point quantity
Card pause point is an index for judging a card situation, and in fact this point is readily appreciated that, such as, the point that in game, delay time is long is many, illustrates that the number of times that game card pauses is more, plays more not smooth certainly to the sensation of people exactly.In this programme, the preset rules of doubtful card pause point is:
Described card pauses in time-delayed sequence D and is greater than the point of more than predetermined threshold value as doubtful card pause point than described card the pause mean value average of delay data of all cards in time-delayed sequence D that pauses.That is if: D (i)-average> predetermined threshold value, then i is doubtful card pause point.
In the present embodiment, described predetermined threshold value is 20ms.In screen display, the selection of 20ms is the average delay time that can identify according to human eye.If doubtful card pause point is more, instruction card situation of pausing is more serious.Namely the doubtful card pause point quantitative value calculated can be paused as analyzing card an index of situation.
Index three, 95% accounting delay inequality
95% is the critical value defining small probability event in theory of probability, if the probability of a thing generation is less than 5%, so can think that it is small probability event.Such as, when game screen time delay accounting is greater than 95% time, can think and almost comprise all card pause points, be positioned at the pause difference of delay value average of the minimum time delay of this accounting and mean 0100 calorie and be this desired value, the size reflection of this value be that card pauses the vibrations scope of time delay, be appreciated that this vibrations scope is less, illustrate that duration curve is relatively more level and smooth, play also more smooth.
First, define time delay accounting function p (d), this time delay accounting p (d) illustrates, in all data of a card time-delayed sequence D, time delay is less than or equal to the ratio data of d, such as:
Suppose a card time-delayed sequence D=[21,33,46,50,62,69], so,
p(30)＝1/6
p(60)＝4/6
p(70)＝1.0
To be paused by computer card the time delay accounting of time-delayed sequence D, can obtain one " time delay/accounting curve ", as shown in Figure 4.
Wherein, 95% this index of accounting delay inequality refers to the minimum d value that meets time delay accounting function p (d) >=95% and mean 0100 calorie and to pause the difference of delay value average.The card of this value reflection pauses the scope of time delay and concentrated situation.The accounting of >=95% can think most time delay all within this scope, to pause the difference x of delay value average, represent that most of data all restrain in the scope of average+x, as shown in Figure 4 with mean 0100 calorie.
Visible, when 95% this index of accounting delay inequality is less, the data that instruction card is paused in time-delayed sequence D more concentrate near mean value average, and it is also faster that curve rises, and plays also more smooth.
To pause information (comprising at least one index in delay time variance, doubtful card pause point quantity, 95% accounting delay inequality) at the card obtained after step S103, display screen can be sent to carry out showing or send to storage unit to store.
In addition, for different application (such as, dissimilar game), can be obtained and the card stored pauses information (comprising at least one index in delay time variance, doubtful card pause point quantity, 95% accounting delay inequality) by the embodiment of the present invention and carry out contrast conclusion, the card be convenient between different game situation of pausing contrasts.Table 4 pauses detection method to 3 different correlation datas after carrying out a card detection of playing by the card of the embodiment of the present invention:
Table 4
Visible, utilize data can obtain multiple game card clearly and to pause situation comparing result, measure a card order of severity with the index of reasonable science, the card of the different game of convenient contrast pauses degree, instructs development of games to improve game, improve the Consumer's Experience of game with this.Therefore, the card utilizing the embodiment of the present invention to obtain information of pausing is analyzed between difference game has objective meaning.
The card of the present embodiment pauses the time that detection method is changed by the rgb value that the framebuffer device file monitoring Linux carrys out some pixels on real-time monitoring screen, efficiently (Millisecond) time stamp data of pixel change can be gathered, thus improve sample frequency; Carry out processing based on the sampled data of such real-time high-efficiency within a test period and calculate to obtain, as some indexs of a card analysis result, making analysis result more careful and accurate.
