For solving the above problems, in embodiment of the disclosure, terminal can obtain projection information, and projection information is sent To projector, projector determines the Focusing parameter of itself it is not necessary to projector measurement is used for by the projection information that terminal sends Calculate each item data of Focusing parameter, the hardware decreasing projector puts into, and has saved the process resource of projector.
The embodiment of the present disclosure provides a kind of projector focusing method, as described below：
Projector side
Fig. 2 a is a kind of flow chart of the projector focusing method according to an exemplary embodiment, and the method is applied to Projector, projector can by image projection to projection screen or projection metope, wherein, projection screen or projection metope institute Plane be perspective plane.As shown in Figure 2 a, the method comprises the following steps 201 to step 203：
In step 201, the projection information that projector receiving terminal sends.
Wherein, the projection relevant information of the projector that projection information collects for terminal.This projection information can include with At least one lower：Between the first relative position information between terminal and the perspective plane of projector, terminal and projection lens Two relative position informations, the second Focusing parameter of the photographic head of terminal, the first Focusing parameter of projector projection lens, environment are bright Angle value etc..Example, after terminal gets projection information, by infrared connection or bluetooth connection, projection information can be sent out Give projector, or projection information can also be sent to projector by WLAN by terminal.
In step 202., described projector determines the first of the projection lens of described projector according to described projection information Focusing parameter.
Example, the first Focusing parameter can include at least one of focal distance, focusing angle or focusing points.Its In, focal distance refer to projection lens to distance and the projection lens on perspective plane to photo-sensitive cell apart from sum；Focusing angle It is the axis of projection lens and the relative angle on perspective plane in projection；Focusing points are the finding a view of projection lens in projection The focus quantity that can find in interface.
For example, it is assumed that putting in the case of the relative distance that projection information is included between terminal and the perspective plane of projector The relative distance reflected between the relative distance between camera lens and perspective plane and terminal and perspective plane is equal, because projector shows mirror Head to photo-sensitive cell distance it is known that therefore projection lens arrive the distance on perspective plane and projection lens to photo-sensitive cell distance it With the focal distance for projection lens.In addition, according to imaging in projection lens for the perspective plane under this focal distance, you can obtain The focusing angle of projection lens and focusing points.
In step 203, described projector controls described projection lens to be focused according to described first Focusing parameter.
Example, projector is according to the first Focusing parameter obtaining, the angle of adjustment projection lens and each light of optical system Learn the position of element so that the projection lens of projector is focused to projection screen or projection metope, and then can be in projection screen The picture of complete display is presented on cloth or projection metope.
In the technical scheme that embodiment of the disclosure provides, projector determines itself by the projection information that terminal sends It is not necessary to projector measures each item data for calculating Focusing parameter, the hardware decreasing projector puts into Focusing parameter, section The about process resource of projector.
In one embodiment, described projection information includes first between described terminal and the perspective plane of described projector Relative position information.As shown in Figure 2 b, in step 202., described projector determines described projector according to described projection information Projection lens the first Focusing parameter, can be realized by step 2021 and step 2022：
In step 2021, described projector obtains the second relative position letter between described terminal and described projection lens Breath.
Example, the first relative position information can be the distance between perspective plane of terminal and projector, and second relatively Positional information can between terminal and the projection lens of projector along perspective plane vertical direction distance.
Due to the essence being positioned by GPS (Global Positioning System, global positioning system) in correlation technique Really property is very high, and popularity in the terminal is higher, and therefore projector can be carried out by the GPS positioning device that itself carries Positioning, terminal also can be positioned by the GPS positioning device that itself carries, and the two carries out location information based on communication module again Interaction, and then obtain between terminal and the projection lens of projector along perspective plane vertical direction distance.
In the case that one kind is possible, as shown in Figure 2 c, the plane at the projection lens 20a of projector and terminal 20b place Parallel with perspective plane 20c, projector and terminal can be positioned by the GPS positioning device that itself carries respectively, and to positioning Information interacts, you can getting projection lens 20a and terminal 20b along the vertical direction of perspective plane 20c is 0 apart from L3, I.e. projection lens 20a and perspective plane 20c be equal to terminal 20b with perspective plane 20c apart from L2 apart from L1.
In the case of alternatively possible, as shown in Figure 2 d, projection lens 20a is vertical along perspective plane 20c with terminal 20b There is certain distance L 3 in direction.If the axis of the photographic head 20b1 of the axis of projection lens 20a and terminal 20b is each perpendicular to Perspective plane 20c, projector can directly be positioned by the GPS positioning device that itself carries, and terminal 20b also can pass through itself The GPS positioning device carried is positioned, and the two interacts to location information, thus obtaining projection lens 20a and end End 20b is along the vertical direction of perspective plane 20c apart from L3.
Or, in practical application, there is also the axis of projection lens 20a and the axis of terminal 20b photographic head 20b1 Uneven situation.In order to accurately obtain projection lens 20a and the distance between terminal 20b L3, terminal can adjust certainly first Body direction is so that photographic head 20b1 axis is perpendicular to perspective plane 20c；Then photographic head 20b1 axis is obtained by compass Direction, and the direction is sent to projector；Projector adjusts the direction of projection lens 20a so that putting by rotation motor Reflect the axis of camera lens 20a and the axis parallel of photographic head 20b1；And then, projector and terminal are respectively by itself carrying GPS positioning device is positioned, and location information is interacted, thus obtaining projection lens 20a with terminal 20b along perspective plane The vertical direction of 20c apart from L3.
For example, terminal 20b adjusts photographic head 20b1 axis to after vertical with perspective plane 20c, is obtained by compass The direction getting photographic head 20b1 axis is 56 ° of northeast, and the direction is sent to projector, is also equipped with referring in this projector Compass.Projector adjusts the direction of projection lens 20a axis so that the side of projection lens 20a axis by rotation motor To being similarly 56 ° of northeast, now projector is positioned by the GPS positioning device that itself carries, and terminal 20b is also by certainly The GPS positioning device that body carries is positioned, and the two interacts to location information, you can obtain projection lens 20a with Terminal 20b is along the vertical direction of perspective plane 20c apart from L3.
Or, the angle of projection lens 20a can not also be adjusted in the case, terminal 20b can obtain shooting first The distance between the photocentre of the photocentre of head 20b1 and projection lens 20a S, and two photocentre place rectilinear directions and perspective plane 20c Vertical direction between angle i, and this is sent to projector apart from S and angle i, scialyscope can according to this apart from S and Angle i calculates projection lens 20a and the distance between terminal 20b L3.
In one embodiment, described projector can directly receive the described second relative position letter that described terminal sends Breath.
Example, with reference to shown in Fig. 2 d, terminal 20b getting terminal 20b with perspective plane 20c after L2, Can be positioned by the GPS positioning device that terminal and projector itself carry respectively, and location information is interacted, be obtained Take projection lens 20a and terminal 20b along the vertical direction of perspective plane 20c apart from L3, then by get apart from L2 and away from Carry in projection information from L3, be sent to projector.
In step 2022, described projector is according to described first relative position information and described second relative position letter Breath, determines described first Focusing parameter.
Example, in the first scenario, the distance of projection lens 20a and the vertical direction along perspective plane 20c for terminal 20b L3 is 0, now projection lens 20a and perspective plane 20c be equal to terminal 20b with perspective plane 20c apart from L2 apart from L1.Projector After receiving the projection information of terminal transmission, can directly terminal 20b be appointed as showing apart from L2 with perspective plane 20c Camera lens 20a and perspective plane 20c apart from L1.And the first Focusing parameter is determined apart from L1 according to this, this first Focusing parameter includes Focal distance, focusing angle and/or focusing points, wherein, apart from L1 with projection lens 20a to photo-sensitive cell apart from sum be For focal distance.According to imaging in projection lens for the perspective plane under this focal distance, you can obtain the focusing of projection lens 20a Angle and focusing points.
In another case, projector apart from L2 and is obtained with perspective plane 20c according to terminal 20b that terminal sends first The distance between the projection lens 20a getting and terminal 20b L3, obtain projection lens 20a and perspective plane 20c apart from L1, L1 =L2+L3.Then the first Focusing parameter is determined apart from L1 according to this, this first Focusing parameter includes focal distance, focusing angle And/or focusing points, wherein, it is focal distance to photo-sensitive cell apart from sum apart from L1 and projection lens 20a.According to this Imaging in projection lens for the perspective plane under focal distance, you can obtain focusing angle and the focusing points of projection lens 20a.
