Suppose that horizontal direction is X-axis, vertical direction is Y-axis, directly over the sight line of people is displaced to by calibration point in addition a bit, the Y direction angle read at this point is β 1, the angle value that calibration point reads is β 2, so just can calculate the distance in Y-axis according to the angle relativity shift value of Y direction, namely current gaze is in the distance of calibration point.
△β＝β1-β2
Ly＝tan△β*distance
Wherein △ β represent initial with at the end of angle difference (Circular measure).Distance is the value that aforementioned formula alignment calculates.
Because display wall is plane, basically identical in the computing method in X-direction and Y-axis.X-direction is circular arc, repeats no more.Directly provide the distance in X-direction:
△α＝α1-α2
Lx＝△α*distance
If using calibration point is as the initial point of two-dimensional coordinate, any point coordinate that so on wall, sight line is seen just can be obtained by formula above:
On wall, any point is relative to coordinate=(Lx, the Ly) of calibration point;

People calculates at the outer any point coordinate of wall, can consult Figure 13, for the coordinate of window operation personnel when any point of window operation method of the present invention calculates one of schematic diagram.
Display metope is ABCD, and the size of metope is known.
AB is circular arc, and AD is straight line, and display wall is all generally build according to viewing ratio, therefore OD is known, set up coordinate system as shown in the figure with the center O of cylinder for true origin, suppose people any point P before wall, during calibration, P point sends ultrasound wave resolved measurement to A, the distance that B, D are 3
PA＝V0*Ta/2
PB＝V0*Tb/2
PC＝V0*Tc/2
Wherein V0 is hyperacoustic speed, is known constant, and Ta, Tb, Tc are the time that ultrasonic transmission/reception is used, and it is also known that the processor on glasses is measured.If P point coordinate is (X, Y, Z), calculate P point coordinate value below.
∠ DOC=CD/OD (Circular measure)
The coordinate of A is (OD*sin ∠ DOC, OD*cos ∠ DOC, AD)
The coordinate of B is (0, OC, AD)
The coordinate of C is (0, OC, 0)

The coordinate figure of P point can be drawn by above-mentioned three formula group solution ternary quadratic equation groups.The position that calculating arbitrfary point P sight line moves on rear wall is below determined.
Refer to Figure 14, for the coordinate of window operation personnel when any point of window operation method of the present invention calculates schematic diagram two.
As shown in figure 14, the sight line of people stops S1 place on the wall, first calculates S1 point coordinate (Xs, Ys, Zs).
This formulae discovery of distance of P to S1:
PS1＝V0*Ts1/2
S1 must meet Xs on the face of cylinder
2+ Ys
2=OD

PS1
2＝|Xs-Xp|
2+|Ys-Yp|

The S1 that corrects one's mistakes in fig. 14 is the vertical line S1R of XY axle, cross the PQ that slavers over that P makes XY axle, coplanar by the knowledge PQRS1 of solid geometry, and PQRS1 forms a right-angled trapezium, cross P and make the vertical and S1R of PG, if human eye is being just PG to so its sight line of wall, if had, to offset so ∠ GPS1 be exactly the deviation angle of sensor measurement.In triangle PGS1,
PS1＝|Zs-Zp|/sin∠GPS1
The coordinate of any point on wall just can be calculated by aforementioned formula.
Calculate wall uplifting window length and width below: the length of wall is the length of circular arc, and the width of wall is the difference of Z coordinate, as shown in figure 14.
Figure 14 is vertical view, only gets XY coordinate plane and gets final product computational length, supposes have S1 to move to S2, S1 can be calculated, the coordinate (X1, Y1) of S2 according to inference above, (X2, Y2), all can obtain the length of circular arc after calculating ∠ S1OS2.
tan∠1＝|X1|/|Y1|
tan∠2＝|X2|/|Y2|
So ∠ S1OS2=π-arctan (| X1|/| Y1|)-arctan (| X2|/| Y2|), what calculate is Circular measure herein.
The length of windowing=arc S1S2=∠ S1OS2*OD.
The height of windowing=| Zs2-Zs1|.
So far, people just completes in the computation process of any point operation coordinate.
