The location information of mouth) it can be acquired.Wherein, the location information of ball can be coordinate information, can identify the ball
Specific location on table top, in order to position its relevant position in subsequent calculating process；The ball of ball be identified as
Type, the color etc. of different balls are identified, for calculating corresponding score during subsequent.It in the present embodiment, can be with
Different balls is identified by letter or number.For example, mother bulb is identified as W1, red ball in snooker
Be identified as R, the mark of colour ball can also be identified according to the color of colour ball, wherein the mark for being identified as Y, green ball of yellow ball
To know be G, coffee ball be identified as C, basketball be identified as B, the sphere of powder be identified as P, black ball is identified as H.For another example opening human relations
In billiard ball, mother bulb or cue ball are identified as W or Y, and red ball is identified as R.It specifically can be according to the ball in corresponding billiard ball type
It quantity and is specifically identified to be classified and be determined.
After the position of each ball on table top determines, that is, all choosings for can determine player currently and can batting
It selects.
Step S104: determining at least one batting corresponding with the current table top selects and corresponding with batting selection
Batting parameter, determine with each corresponding batting financial value of batting selection, the batting parameter including at least direction of stroke,
One or more of cue power and/or hitting point position, it is corresponding with batting selection according to batting parameter determination
Income probability.
In the present embodiment, batting each time can be according to the direction (direction of stroke) of batting, hitting point position, batting
The relevant batting parameter such as dynamics determines, the road that changes of any one batting parameter may bring the ball after batting to be walked
Line, the difference of collision situation and score namely different batting parameters have corresponded to different results.
For example, in the case where considering batting parameter includes direction of stroke, hitting point position, this 3 factors of cue power
(other factors may also impact batting, but wouldn't be considered in the present embodiment), direction of stroke include level side
To with vertical direction (prick bar angle), horizontal direction includes 0-360 °；Hitting point position is with the position of club impact Archon, example
Such as, the high and low position and left-right position of hitting point；Cue power shows as the initial velocity etc. when Archon is knocked off.
For the ease of being calculated, in the present embodiment, batting parameter can be subjected to discrete quantized, direction of stroke includes
Horizontal direction and vertical direction (pricking bar angle) only consider that (direction of stroke referenced below refers to horizontal direction in the present embodiment
Horizontal stroke direction), for ease of calculation, with 1 degree for interval in specific implementation, by direction of stroke be quantified as 360 kinds of directions (
It, can also be with 0.5 degree for interval or using other intervals in other embodiments)；Hitting point position is to strike Archon with club
Position, as shown in Fig. 2, specific implementation can be quantified as the left plug of middle bar, high bar, low bar, middle bar, the left plug of high bar, a low bar left side
9 positions such as the right plug of plug, middle bar, the right plug of high bar, the right plug of low bar (in other embodiments, can also carry out hitting point position
The segmentation more refined)；Cue power shows as initial velocity when Archon is knocked off, during specific implementation can be quantified as
Power, medium and small power, small power, in 5 kinds of dynamics (in other embodiments can also carry out the quantization of cue power energetically, energetically etc.
Thinner division).Under above-mentioned quantization scheme, primary batting includes that 360 × 9 × 5=16200 kind is possible, namely there are 16200
Middle batting selection, and each batting selection corresponds to different batting parameters.
That is, in the present embodiment, according to the batting such as direction of stroke, cue power and/or hitting point position parameter
Possible value range (default value range), determining multiple parameters of batting corresponding with the value of different batting parameters
Combination (batting combination), each batting combination are a kind of batting selection.
Further, batting group in part, which is combined into, invalid (such as score or can not have the obstacle ball that can not be struck
Deng), in specific calculating process, the batting combination of the part is scored at 0.In this case, considering various batting choosings
When selecting, directly this kind can also not batted to combine is calculated in the batting selection determined in step S104.Specifically, judgement is true
Fixed batting combination whether with preset batting rule match, which is the rule of corresponding billiard ball type, for example,
When secondary should strike is red ball in snooker.The case where determining batting combination is with preset batting rule match
Under, by batting combination as one of batting corresponding with the current table top selection determined in step S104.
It should be noted that in the present embodiment, above-mentioned direction of stroke, batting can be not limited to when considering to bat parameter
Dynamics, the batting parameter of hitting point position this 3 can also may influence the batting parameter of batting result comprising other.Also,
In other embodiments, the factor considered in impact can also be reduced, only with above-mentioned direction of stroke, cue power, batting
The factors considered during some or certain several auxiliary recommendations as batting in point position this 3 batting parameter.Example
Such as, direction of stroke can only be considered for low order player, but for high-order player can be considered direction of stroke, cue power,
The batting parameter of hitting point position this 3.Therefore, before carrying out batting auxiliary, it is also necessary to determine the rank or preference of player
Deng to carry out personalized setting.
After determining batting selection according to batting parameter, it can determine according to the location information of the ball on current table top
The batting select lower ball track and with the collision situation of Ku Bian and/or ball or whether have ball into sack, so as to true
Determine the corresponding score of this time batting, which is the batting financial value under batting selection.
Specifically, according to batting parameter, the ball mark of multiple balls and location information and preset physical model determine with
Batting selection it is corresponding walk course of action line, that is, determine the associated crash information such as collision side of the ball in the track of movement, collision ball, and
And determine the motion profile and final stop position of each ball after collision, be also included in the case where marsupial billiard ball into
Ball situation, to calculate corresponding batting financial value according to preset batting score computation model.
Different combinations between batting parameter have determined batting selection, the group of the corresponding batting parameter of a batting selection
Conjunction is more, and the probability of score is higher.In the present embodiment, a batting selection can only correspond to the group of each batting parameter
It closes, scoring probability (i.e. income probability) is 1；In another embodiment, a batting selection can correspond to multiple batting ginsengs
Several combinations (combination of one group of batting parameter), for example, direction of stroke is 90 degree, hitting point position can be middle bar, high bar, low
9 positions, the cue powers such as the left plug of bar, middle bar, the left plug of high bar, the left plug of low bar, the right plug of middle bar, the right plug of high bar, the right plug of low bar are
Middle power, in energetically, 3 dynamics selections such as energetically, batting selection includes the combination of 1 × 9 × 3=27 batting parameter, receipts
Beneficial probability is 27.
It should be noted that the possible corresponding completion of different direction of stroke, hitting point position and cue power is general
Rate is different, for example, player is easy to appear batting error, and when cue power is middle power, player is not when cue power is small power
It is easy to appear very much batting error, therefore, when calculating income probability, it is also contemplated that corresponding difficulty or ease under unused batting parameter
Degree.
Step S106: according to preset income calculation model and the batting financial value, the income probability, calculate with
Each batting selects corresponding expected revenus value.
According to foregoing teachings, each batting selection has been corresponded to corresponding to its corresponding batting financial value and the income
Income probability, according to batting financial value and income probability can calculate expected revenus situation corresponding with batting selection,
Expected revenus value i.e. corresponding with batting selection.
For example, in one embodiment, expected revenus value is equal to the product of batting financial value and income probability, that is,
It says, preset income calculation model is are as follows:
Expected revenus value=batting financial value × income probability.
It should be noted that in the present embodiment, the calculating of expected revenus value can also be consideration repeatedly batting or the
Score does not change the defence situation in the case where other side's batting for primary batting.That is, batting selection include for the first time batting and
Batting (second of batting), even last call again.
In the case where considering repeatedly batting, the case where calculating expected revenus value, is also required to point multistep and carries out.
Specifically, as shown in figure 3, including following step S202-S206:
Step S202: the situation of Profit of batting for the first time is calculated: according to the corresponding batting financial value, income of batting for the first time
Probability calculates and corresponding first expected revenus of batting for the first time；
Step S204: under each batting selection of first time batting, calculating bats again or repeatedly bats corresponding
Income of batting and income probability, and determine its corresponding second expected revenus, wherein the second expectation financial value is for being characterized in
The score situation of Profit batted again and/or repeatedly under batting selection；
Step S206: the expected revenus value is determined according to the first expected revenus and the second expected revenus, for example, according to pre-
If expected revenus formula calculate expected revenus value.
The calculating of expected revenus value is illustrated below.
Specifically, only to consider to be illustrated for secondary batting, that is to say, that batting selection is only contained hits when secondary
Ball is batted for the first time when the batting of secondary batting is selected as.That is, need to first time bat under score situation of Profit into
Row explanation.
Expected revenus value calculation formula are as follows:
E=P1G1,
It is wherein E expected revenus value, P1For income probability, G1For financial value of batting.
Situation of Profit in the case where considering to bat twice, in addition to calculating batting for the first time, it is also necessary to deduce respectively
Situation after being batted with this bats again to every kind of situation consideration and calculates its situation of Profit.
The calculation formula of expected revenus value are as follows:
E=E1+E2=P1G1+P1P2G2,
Wherein, E is expected revenus, E1For the first expected revenus, E2For the second expected revenus, P1For the receipts of first time batting
Beneficial probability, G1For the batting financial value of first time batting；P2For the income probability of second of batting, G2For hitting for second of batting
Ball financial value.
By taking the quantization of aforementioned batting parameter as an example, in the case where considering to bat twice, when considering batting selection, need
Including 162002Kind combination；And so on, if considering continuous n times batting, need to consider 16200 in totalNKind combination.
Step S108: determining target batting selection at least one described batting selection according to the expected revenus value,
Export the target batting selection.
In general, player is when hitting the ball, it is desirable to which the corresponding maximum revenue of batting selection is received in the present embodiment
Benefit, which maximizes, can show as the maximization of expected revenus value.
In this step, each batting is selected, maximum revenue is selected as that expected revenus value is maximum to hit
Ball selection, also as target batting selection.That is, being equivalent in the combination of aforesaid plurality of batting parameter, determine
The optimal combination of its situation of Profit, the optimal combination are target batting selection.
In the present embodiment, according to expected revenus maximization principle, target batting selection is determined in batting selection, and is obtained
Target batting selection batting parameter is taken, and is exported, thus to assist sportsman or player to bat.It needs to illustrate
It is that in the present embodiment, the batting selection that the batting selection of output can bat more than once (can be only comprising when time batting
Batting selection, also may include multiple batting batting selection).
Further, in the present embodiment, output target bat selection mode can be carried out in a manner of text it is defeated
Out (for example, by display screen output character, alternatively, being prompted by voice), it is also possible to carry out in visual form
Output, for example, being shown by the line map of display screen output simulation, or by being projected on Billiards table.
As previously mentioned, in the present embodiment, obtaining when time batting can be only considered during considering maximum revenue
Divide income (i.e. the first expected revenus), it is also contemplated that corresponding score incomes except when other times except secondary batting are batted
Situation (i.e. the second expected revenus).In order to further improve user experience, batting is considered during considering score income
Step number can be configured, for example, being configured according to the different rank of player, for example, only being examined for primary player
Consider when time batting or bat twice, for high-order player, considers batting twice or more than twice.That is, can
To be determined according to the rank of player, or it is determined according to the input of user.
It should be noted that in the present embodiment, also needing to consider target batting selection when considering target batting selection
Whether corresponding expected revenus value reaches expected, if do not reached expected, it is believed that current income is excessively poor, it may be considered that
Other schemes, such as defend.
Specifically, during determining target batting selection, it is also necessary to which the expectation determined in each batting selection is received
Whether the expected revenus value of the maximum selection of batting of beneficial value is greater than or equal to preset score threshold, only in its expected revenus value
In the case where more than or equal to preset score threshold, the batting is just selected as target batting selection., whereas if the phase
It hopes financial value be less than preset score threshold, then needs to consider other strategies.In the present embodiment, defence situation can be continued with
Under situation of Profit.
Specifically, being determined in the case where the expected revenus value of the selection to be selected of batting is less than preset score threshold
Defence financial value corresponding with each batting selection, the defence financial value select lower opposing team for being characterized in the batting
The score income of batting；Target batting selection is determined according to the income probability and the defence financial value.
Considering the not score (G of batting for the first time1=0) it, changes other side to bat, then other side may score or may also
It loses points.In this case, financial value E is defended3Other side's situation of Profit under different batting selections, E is desired financial value:
E=P1/E3=P1/P3G3,
Wherein, P3For the income probability of other side's batting, G3For the batting financial value of other side's batting.
That is, target is batted, the determination of selection is that expected revenus value is the bigger the better, and is also to bat for the first time in place
Probability it is bigger, the probability of success of other side's batting is small, income is small.
In the batting selection that different batting parameter determines, there are multiple batting select between be it is similar, adjacent,
For example, only there are 1 degree of difference (210 degree, 211 degree) for direction of stroke, other batting parameters are identical, and score income is also identical,
That is in this case, player can choose any angle in 210-211 degree.
In the present embodiment, similar, adjacent batting as described above a combination cluster can also be selected as (to hit
Ball combines cluster).By taking snooker as an example, it is assumed that direction of stroke be one of 50 degree, 51 degree, 52 degree, hitting point position be middle bar,
One of high bar, low bar, cue power be middle power, in one of energetically, totally 3 × 3 × 2=18 kind batting selection constitutes batting combination
Cluster, the batting financial value of this 9 kinds of selections of batting all are available 3 points, then batting financial value is 3.For another example direction of stroke
Be one of 210 degree, 211 degree, hitting point position be middle bar it is left plug, high bar it is left plug one of, cue power be middle power, medium and small power, in
One of energetically, totally 2 × 2 × 3=12 kind batting selection constitutes batting combination cluster, and the combined batting financial value of this 12 kinds batting is all
It is available 5 points, then batting financial value is 5.
That is, in the present embodiment, financial value of batting according to batting parameter and accordingly, to multiple batting selection
Classified or clustered, all batting selections are divided into multiple batting and combine cluster, wherein the institute in each batting combination cluster
Batting select corresponding batting financial value be it is identical, the value for parameter of batting is continuous.
Further, in the present embodiment, the process of the subsequent expected revenus for calculating selection of batting can be calculating batting
The process of the corresponding expected revenus value of cluster is combined, the target batting of final output selects also as output one optimal batting combination
Cluster.
Specifically, in one embodiment, calculating each corresponding expected revenus value of batting combination cluster.For example, calculating
The multiple batting for including in batting combination cluster select the process of the sum of corresponding expected revenus value.
In a specific embodiment, as it is aforementioned batting combination cluster example, it is assumed that direction of stroke be 50 degree, 51 degree,
One of 52 degree, hitting point position is one of middle bar, high bar, low bar, cue power be middle power, in one of energetically, totally 3 × 3 × 2=
18 kinds of batting selections constitute batting combination cluster, and the batting financial value of this 9 kinds of selections of batting all is available 3 points, then hitting
Ball financial value is 3, and income probability is 18, and expected revenus value is 18 × 3=54.For another example direction of stroke be 210 degree, 211 degree it
One, hitting point position is one of the left plug of middle bar, the left plug of high bar, cue power be middle power, medium and small power, in one of energetically, totally 2 × 2
The batting selection of × 3=12 kind constitutes batting combination cluster, this 12 kinds combined batting financial values of batting are all available 5 points,
So batting financial value is 5, and income probability is 12, and expected revenus value is 12 × 5=60.
That is, the calculating process of the expected revenus value of batting combination cluster can be and be selected by batting financial value and batting
It selects quantity determination and combines the corresponding expected revenus value of cluster with the batting, wherein batting selects quantity to combine cluster quilt according to batting
The batting selection quantity for including determines, also as income probability.
When progress target bats the recommendation of selection, output expected revenus is worth maximum batting and combines cluster.As previously mentioned, false
If having to this two expected revenus value non-zeros or the cluster beyond default score threshold (such as 50) in all batting combination clusters, that
Wherein expected revenus only can be worth maximum second batting and combine cluster.Description batting combination cluster can take wherein to be connect as far as possible
The batting parameter of entad describes, such as second batting combination cluster can be described as: direction of stroke is 210 degree, hitting point
Position is the left plug of middle bar, cue power is middle power；Cluster, such as second can also be combined with the virtual batting of its center placement configurations
Batting combination cluster can be described as: direction of stroke is 210.5 degree, hitting point position is the left plug of middle high bar, cue power is middle power.
Likewise, in the case where considering batting twice or repeatedly batting, the also as batting combination of multistep of consideration
Cluster, the calculation formula of expected revenus value are E=P1G1+P1P2G2+…+P1P2…PNGN.Take expected revenus value maximum or biggish
Cluster is combined in the batting of a kind of or several multistep, as recommends the continuous several times batting scheme of sportsman, such as: the batting of the first bar
Direction is 210 degree, hitting point is the left plug of middle bar, cue power is middle power, and the second bar direction of stroke is 120 degree, hitting point is high
Bar, cue power be in energetically.
Likewise, in the case where the batting of the target of the recommendation of final output is selected as a batting combination cluster, equally
Defence can be considered in the case where the expected revenus value of multiple batting combination clusters is less than default score threshold；That is, G1=0, it is right
The calculating of the expected revenus value E answered is as follows:
E=P1/E3=P1/P3G3,
Wherein, P3For the income probability of the batting combination cluster of other side's batting, G3For the batting of the batting combination cluster of other side's batting
