Specific embodiment
Accompanying drawing is combined below by specific embodiment to be described in further detail the present invention.The application provides a kind of 3D
The localization method and device of ball machine, accurately can position to target, and can recover original monitor state.
Embodiment one：
Fig. 1 is referred to, Fig. 1 is the method flow diagram of the embodiment of the present application one, as shown in figure 1, the embodiment of the present application is provided

Wherein, x and y are respectively the transverse and longitudinal coordinate value of the coordinate position of the impact point, and α is the current level of ball machine movement
Visual angle, w is the width of video resolution.
The detailed process and principle that move horizontally angle that the present embodiment step S20 calculates impact point is explained below
State：
As shown in Fig. 2 level walks, principle is according to the position of impact point place screen, current movement horizontal view angle and works as
Front code distinguishability, gets through a series of geometric operations.
Step 1. analyzes target
After the impact point A on screen determines, relevant parameter (abscissa value x and ordinate y) of impact point A of point A
Also determine that.Because the picture of movement collection is spherical, when movement vertical angle is constant to horizontally rotate, each on screen
Impact point all can run along corresponding track.Such as Fig. 2, after impact point A determines, vertical angle of view is constant horizontally rotate when, A points
Track on screen is a fixed camber line.Angle is moved horizontally in order to more accurately calculate, will be corresponding on screen
Spot projection is analyzed on horizontal plane OZN from Fig. 2, and ∠ EOM are the level of impact point A and walk angle, wherein assuming that E is A
Put the location point after moving horizontally.
Step 2. Algorithm Analysis
Because video resolution, movement present level visual angle are known, a width of w of setting video resolution ratio PH, movement is current
Horizontal view angle ∠ HOK are α, and screen perpendicular bisector OK is h, can obtain relationship below：
H=w/ (2*tan (α/2)) is 1.
Due to impact point A coordinates, it is known that i.e. BK=y, if ∠ EOK are β, a length of m of straight line OE, in Vertical Triangular BOK
There is relationship below：
β=atan (| y |/h) is 2.
M=| y |/sin (β) are 3.
Movement current vertical angle is ∠ KOM, and straight line OE and OK is with a plane, if movement is understood to Fig. 2 analyses
Current vertical angle ∠ KOM is ＆, and ∠ EOM are φ, then φ=β+＆, in Vertical Triangular EOM and Vertical Triangular BOM, if
OM is s, and angle on target ∠ BOM are γ, then
γ=atan (| x |/s) is 5.
In sum, 1., 2., 3., 4., 5. can obtain level by formula to walk angle on target γ：
γ=atan (| x | * sin (atan (2* | y | * tan (α/2)/w))/(| y | * cos (＆+atan (atan (2* | y | *
tan(α/2)/w)))))
In the present embodiment, above-mentioned coordinate value according to the impact point on screen, width and height, with reference to the mesh
Punctuate moves horizontally angle, and S30 the step of vertically moving angle for calculating impact point specifically includes：
Angle, θ is vertically moved according to below equation calculating impact point：
θ=asin (2* | x | * sin (β/2)/(w*sin (γ)))-asin (cos (90-＆) * sin (β/2)/w)；
Wherein, γ is the angle that moves horizontally of impact point, and β is the present level visual angle of ball machine movement, and ＆ is when movement is vertical
Angle, w is the width of video resolution.
Below the detailed process and principle that vertically move angle to calculating impact point in the present embodiment step S30 is explained
State：
As shown in figure 3, the principle that vertically walks be according to the position of impact point place screen, current movement vertical angle, when
The horizontal and vertical visual angle of front movement, gets through a series of geometric operations.Vertically walk and dependent, it walks with level phase
Close, the angle for moving horizontally is one of |input paramete as the algorithm that vertically walks.
Step 10. analyzes impact point
After impact point A determines on screen, i.e. impact point A is determined in the coordinate value of screen, wide and higher position.System meeting
The angle that level walks is obtained after computing automatically according to the relevant parameter of target, because the picture of movement collection is for spherical,
Each point i.e. in screen can run on corresponding arc track, and the vertical angle of view of movement is bigger, corresponding to circular arc
Radius is less.Such as impact point A (x, y) in Fig. 3, when movement vertical angle ＆ is constant, point A will be with radius as r2 in screen
Circular arc on move, knowable to top view, A points will move to center's point of screen, and the points of A first will move horizontally γ angles, then enter
Row is vertically moved.Knowable to side view, after the mobile γ angles of A point levels, the upright position (y) of A has occurred and that change, i.e. A
The vertical angle of view of point is altered, changes to B points.Therefore, calculate vertically walk angle when can not with the y values of A points come as
Vertically walk the input variable of algorithm, this can cause vertically to walk be moved through it is many or very few.
Step 20. Algorithm Analysis
From the target point analysis of movement, with reference to top view and side view, the movement angle, θ that vertically walks is：
θ=Φ-α
Before impact point A determines, according to the present level visual angle β of movement, the radius R of sphere can be tried to achieve：
R=w/ (2*sin (β/2)) (1)
Before impact point A determines, according to current vertical angle ＆ of movement, r1 can be tried to achieve：
R1=R*cos (90-＆) (2)
Calculate vertically walk angle when, need the angle that moves horizontally for first determining impact point, then using its number of degrees as hanging down
A points in one of input quantity of straight algorithm, such as Fig. 3, A points can be calculated movement and moved horizontally after determining by the level algorithm that walks
Angle γ, thus can try to achieve r3 such as following formulas：
R3=| x |/sin (γ) (3)
From side-looking map analysis,
α=asin (r1/R), Φ=asin (r3/R) (4)
To sum up analyze, by formula (1), (2), (3), what (4) can obtain point A vertically moves angle, θ：
θ=asin (2* | x | * sin (β/2)/(w*sin (γ)))-asin (cos (90-＆) * sin (β/2)/w)
