Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Term " first " in instructions of the present invention and claims and above-mentioned accompanying drawing, " second ", " the 3rd " " 4th " etc. (if existence) are for distinguishing similar object, and needn't be used for describing specific order or precedence.The data that should be appreciated that such use suitably can exchanged in situation, so as embodiments of the invention described herein for example can with except diagram here or describe those order enforcement.In addition, term " comprises " and " having " and their any distortion, intention is to cover not exclusive comprising, for example, those steps or unit that process, method, system, product or the equipment that has comprised series of steps or unit is not necessarily limited to clearly list, but can comprise clearly do not list or for these processes, method, product or equipment intrinsic other step or unit
The embodiment of the present invention provides a kind of visual angle feedback method, is mainly used in the terminal that shows multidimensional image, and this terminal shows multidimensional image by display screen, and the method flow diagram of the present embodiment as shown in Figure 1, comprising:
Step 101, determines the position of the visual angle feedback thing of multidimensional image.
Here feedback thing in visual angle can comprise human eye, induction pen or staff etc., here do not limit, but due to the difference of visual angle feedback thing, the position of the definite visual angle feedback thing adopting is also different, such as, if visual angle feedback thing is human eye or staff, terminal can be carried out capturing visual and be located human eye or the position of staff by the included camera of this terminal; If feedback thing in visual angle is induction pen, terminal can be determined by the module of in this terminal, this induction pen being responded to the position etc. of this induction pen.
Step 102, measures respectively visual angle feedback thing to the distance between multiple measurement points, and measurement point comprises: visual angle feedback thing is to the vertical projection point of the display screen place plane of terminal.
Be appreciated that, terminal can be used camera included in terminal to measure visual angle feedback thing to the distance between multiple measurement points, here multiple measurement points can comprise the vertical projection point of feedback thing in visual angle to some planes, or visual angle feedback thing is to the vertical projection point on a certain axis etc.And terminal is measured visual angle feedback thing to the distance between which measurement point, be mainly to be decided by the visual angle of visual angle feedback thing a direction of display screen place plane in terminal, the geometry forming to the line of which measurement point at Ji Gai visual angle, the visual angle of a direction feedback thing according to this visual angle feedback thing particularly decides.
Step 103, the distance of measuring according to step 102, calculate the visual angle of visual angle feedback thing at least one direction of display screen place plane in terminal, here the visual angle of visual angle feedback thing a direction of display screen place plane in terminal can be defined as this visual angle feedback thing to the line of the central point of display screen and the angle of this direction, is mainly that the geometry forming by distance and this visual angle of measurement in above-mentioned steps 102 calculates this visual angle.
Step 104, adjusts at the visual angle of at least one direction the multidimensional image that terminal shows according to the visual angle feedback thing calculating.
The multidimensional image of adjusting terminal demonstration at the visual angle of at least one direction according to visual angle feedback thing has various ways, be mainly see terminal show be which type of multidimensional image, such as: what terminal showed is a static square, when visual angle feedback thing (human eye) is vertical with the central point of the display screen of terminal, the square surface that terminal shows is vertical with visual angle feedback thing; In the time that visual angle feedback thing is offset certain number of degrees such as 30 ° left, mean that user wants to see the side on the square left side, now terminal can image, to the right, (for user) be offset 30 °.It is more that thing skew is fed back at visual angle like this, and the skew of the square that terminal shows is just more, but be limited to the visual angle of display screen in terminal, and while being offset 90 ° such as human eye, parallel with display screen, at this moment human eye cannot have been seen the content of display screen in terminal.
What show such as: terminal again is the racing car type scene of game at multidimensional image the first visual angle, in the time that visual angle feedback thing is offset left, mean and need to turn left, the imaging of the racing car that now terminal shows itself can not be offset, but the situation that the scene outside racing car can be turned left according to car is adjusted.
Such as: visual angle feedback thing is a at the visual angle of a direction, terminal can move the multidimensional image of demonstration the angle of a in this direction, by that analogy again.
It should be noted that, terminal can be determined according to some cycles the position of visual angle feedback thing, if detected when the position of visual angle feedback thing changes, and can be for the position after changing, and according to the method in above-mentioned steps 102 to 104, to adjust the shown multidimensional image of terminal.
Visible, in the feedback method of the visual angle of the present embodiment, by measuring visual angle feedback thing to the distance between multiple measurement points, these measurement points comprise the vertical projection point of visual angle feedback thing to the display screen place plane of terminal, thereby calculate the visual angle of visual angle feedback thing at least one direction of display screen place plane in terminal, and adjust according to the visual angle calculating the multidimensional image that terminal shows.So just can feed back in thing and terminal the movement of relative angle between display screen and control by visual angle the demonstration of multidimensional image, and the sensor that need not carry by other user's direction of operating bar or terminal is determined the visual angle adjustment of multidimensional image, reduce the requirement to terminal hardware.
Shown in figure 2, in a specific embodiment, terminal, in the time of the measurement of carrying out in above-mentioned steps 102, specifically can be measured in accordance with the following steps:
A: with the single camera in terminal, or the line mid point of dual camera is initial point, is first direction axle perpendicular to the axle of the display screen place plane of terminal, measures first distance of visual angle feedback thing to the vertical projection point of first direction axle.
B: measure the second distance of visual angle feedback thing to the vertical projection point of the display screen place plane of terminal.
The first distance and the second distance that measure by above-mentioned steps A and B, terminal just can calculate the visual angle of visual angle feedback thing in a direction, terminal in this case, while carrying out above-mentioned steps 103, particularly, the first distance and the second distance of measuring according to terminal, and the line mid point of single camera in terminal or dual camera is to the distance between the central point of the display screen of terminal, calculate the line between the central point of display screen of visual angle feedback thing and terminal, and angle between second direction axle.Wherein, second direction axle is with single camera, or the line mid point of dual camera is initial point, points to the axis of orientation of the central point of display screen.
