Fig. 2 is the module diagram of embodiment 3;
Fig. 3 is the structural representation of embodiment 3.
Embodiment
By reference to the accompanying drawings the present invention is described in further detail below by embodiment.
Embodiment 1:
A kind of binary channels merges projection calibration method, as shown in Figure 1, comprises the following steps:
S101: processing module controls the first projection module to projection screen projection primary importance image, controls the second projection module to projection screen projection second place image.
Projection screen is positioned at the front of the first projection module and the second projection module, and primary importance image and second place image just project on the projection screen.Wherein, primary importance image and second place image can be that visible ray is formed, and also can be that the invisible light such as infrared light is formed, and the two is used for indicating the projected position of projection module, so that follow-up calibration.
S102: induction module obtains primary importance image and second place image position on the projection screen, and this positional information is sent to processing module.
Induction module is arranged on the projection screen, because primary importance image and second place image can be that visible ray is formed, also can be that the invisible lights such as infrared light are formed, induction module can respond to the invisible light such as visible ray or infrared light, thus determine primary importance image and second place image position on the projection screen, then this positional information is sent to processing module.
S103: processing module judges that whether the position of primary importance image and second place image is corresponding.
Because the position of primary importance image in the first projection module drop shadow spread is fixing, the position of second place image in the second projection module drop shadow spread is also fixing, when the first projection module and the second projection module are in calibrating position, primary importance image and second place image certainly exist the corresponding relation on a kind of position, and primary importance image and second place image position have on the projection screen been known by induction module, therefore, can judge primary importance image and second place image whether corresponding.
S104: if not corresponding, processing module controls driver module and regulates the first projection module corresponding with the position of second place image to primary importance image with the projected position of the second projection module.
When primary importance image and second place image not to correspondence time illustrate that the first projection module and the second projection module are not in calibrating position, namely processing module controls driver module and regulates the first projection module corresponding with the position of second place image to primary importance image with the projected position of the second projection module, and also just adjustment the first projection module and the second projection module are in calibrating position.
Embodiment 2:
Preferred as embodiment 1, primary importance image and second place image are formed by infrared light, and induction module is infrared induction module.Because infrared light is invisible, first projection module and the second projection module are when projecting normal images, by the infrared module of inside by primary importance image and second place image projection on the projection screen, can't see during human eye, but the first projection module and the second projection module can adjust calibrating position when projecting normal picture, also can carry out the object of calibrating when reaching work.
Further, the drop shadow spread of the first projection module and the drop shadow spread of the second projection module distributes in the horizontal direction or in the vertical direction distribution.
Embodiment 3:
A kind of binary channels merges projection calibration system, as shown in Figures 2 and 3, it comprises processing module 1, first projection module 21, second projection module 22 and is arranged on the projection screen 4 in the first projection module 21 and the second projection module 22 front, projection screen 4 is also provided with induction module 5, also comprises driver module 3; Processing module 1 to project primary importance image 43 to projection screen 4 for controlling the first projection module 21, controls the second projection module 22 and to project second place image 44 to projection screen 4.Induction module 5 is photoinduction resistance, it is covered with whole projection screen 4, when primary importance image 43 and second place image 44 project on projection screen 4, photoinduction resistance is triggered, thus primary importance image 43 and the position of second place image 44 on projection screen 4 can be obtained, then this positional information is sent to processing module 1.Processing module judges that whether the position of primary importance image 43 and second place image 44 is corresponding, if not corresponding, illustrate that the first projection module 21 and the second projection module 22 are not in calibrating position, then control driver module 3 and regulate the first projection module 21 and the second projection module 22, the projection angle of adjustable first projection module 21 and the second projection module 22 and the spacing distance of the two, be finally adjusted to primary importance image 43 corresponding with the position of second place image 44.
In the present embodiment, the first drop shadow spread 41 of the first projection module 21 and the second drop shadow spread 42 of the second projection module 22 distribute in the horizontal direction.In Fig. 2, primary importance image 43 and second place image 44 are "+" shape that grid line bar is formed, when its position is to illustrating during correspondence that the first projection module 21 and the second projection module 22 are in calibrating position.
Above content is in conjunction with concrete execution mode further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made.
