Embodiment 1

[0047]实施例一是利用使用者与基准屏位置相对固定出发的,通过获取参考屏与基准屏之间的角度,而实现对图像进行与视点角度相适应的调整和显示。

[0048] 首先,设定使用者正前方的显示屏为基准屏,其余为参考屏,获取各参考屏与基准屏之间的角度,并将角度传送给控制器;然后,当有图像要在某参考屏上传输的时候,控制器利用获得的该参考屏与基准屏角度,对图像进行变换;最后,将变换后的图像传送给显示屏进行显示。

[0049] figure 2 是本发明中多屏显示场景示意图,其中,显示屏202位于使用者的正前方,作为基准屏,相应地,显示屏201、203作为参考屏,而且各显示屏都是垂直地面放置的;坐标轴x、y分别代表基准屏202显示平面的水平方向和垂直方向,显示屏202作为基准屏它的默认坐标是(0,0)。 Depend on figure 2 可知,基准屏与参考屏的y轴是重合的,所以只考虑在x轴方向的夹角即可。显示屏201与显示屏202之间的夹角为225°,显示屏203与显示屏202之间的夹角为-45°。参考屏与基准屏之间的角度可以通过测量得到,包括自动测量和手动测量;优选地,通过在每个参考屏上安装角度感应装置获得;或者,在基准屏上安装角度感应装置统一获得各参考屏相对角度。

[0050] 在获取到参考屏与基准屏之间的角度之后,将此角度传送给控制器。此控制器对参考屏要显示的图像进行变换,变换的依据就是此参考屏与基准屏的角度。

[0051] Such as image 3 所示,实施例一的实现流程包括:

[0052] 步骤301:设定一个基准屏,除基准屏外的作为参考屏;一般设定正面正对使用者的显示屏为基准屏,设置基准屏的基准角度X(0),例如X(0)为0°;X代表此角度是与x轴方向的夹角;

[0053] 步骤302:获取各参考屏与基准屏的角度X(1)、X(2)....X(n),其中1,2...n代表参考屏序号;可利用在每个参考屏上安装角度感应装置,通过角度感应装置自动得到各角度;

[0054] 步骤303:将X(1)、X(2)....X(n)传送给控制器;

[0055] 步骤304:判断是否有传往第i个参考屏的图像,若有,执行步骤305,否则,执行步骤307;

[0056] 步骤305:控制器利用X(i)对图像...

Embodiment 2

[0061] 与实施例一通过获取参考屏与基准屏的角度不同,本实施例直接获取使用者与显示屏的角度;控制器根据参考屏与使用者的角度,对其要显示的图像做适应性调整,以保证显示效果。

[0062] Such as Figure 4 所示,显示屏401与显示屏402成一定角度放置在使用者前方,由于二者与使用者相对位置和角度相似,所以直接利用使用者作为角度基准;坐标轴x、y是以使用者为基准的,分别代表使用者两侧连线方向,以及从身体向头方向,若使用者端正站立或正坐,就可以得知他的默认坐标是(0,0)。可得到,显示屏401与x轴为225°,显示屏402与x轴为-45°。

[0063] 显示屏401(402)与使用者之间的角度可以通过测量得到,包括自动测量和手动测量;优选地,通过在使用者401的座位上安装角度感应装置而实现。

[0064] 对于实施例二的其余步骤,与实施例一类似,在此不再赘述。

Embodiment 3

[0066] 上面实施例一与实施例二都是对沿水平方向伸展的显示屏进行阐述,本发明还适用于沿竖直方向伸展的多屏显示。

[0067] Such as Figure 5 所示,包括作为基准屏的显示屏502,以及其两侧的显示屏501、503,还有在上方的显示屏504。对于这种多屏显示,两侧的显示屏501、503采用上述介绍的方法,而对显示屏504图像的调整方法与此类似,只不过是在确定其与基准屏或使用者的角度关系时,是通过y轴上的角度来确定的。显示屏504与显示屏502在y轴上的角度为45°,在x轴方向重合。其它步骤与实施例一或实施例二类似,在此不再赘述。

[0068] 对于在x轴和y轴都与基准屏或使用者存在角度的显示屏,需要同时考虑两个方向的夹角,控制器在对发往此显示屏的图像进行变换时,变换依据也是x轴和y轴两个方向的夹角。

[0069] 下面介绍实施例四。

[0070] 与前面三个实施例不同,实施例四不需要采用角度感应装置,控制器直接在其内部对机械调整参数进行解析,就能获取各显示屏的视点角度,从而利用视点角度对图像进行相应变换。

[0071] 对显示屏的位置进行调整,可以采用手动方式,优选地,实施例四在显示屏上安装机械调整装置,此机械装置在控制器的控制下对显示屏的物理位置进行调整,从而,显示屏与使用者的视点角度就发生了改变。 具体是,控制器内部保存有机械调整参数,此机械调整参数可以预先设置,也可以由使用者实时更新和设置,可以由显示屏序号、调整方向和调整幅度等组成;在要对显示屏的位置进行调整时,将此机械调整参数发送给机械调整装置,驱动其执行调整动作。 可见,控制器主动掌握显示屏的视点角度,就不需要角度感应装置为其提供。 still with figure 2 为例,控制器设置显示屏202为基准屏,分别对显示屏201、203的机械调整参数进行设置:显示屏201:序号1、调整方向x轴、调整角度225°;显示屏203:序号3、调整方向x轴、调整角度-45°。控制器通过解析机械调整参数就能获知显示屏的视点角度,然后利用视点角度对图像作适应性调整。可见,由控制器统一控制,显示屏与图像的调整是相应、协调进行的,准确高效,不需要使用者介入,非常方便。

[0072] 特别说明的是,安装机械调整装置对显示屏物理位置进行调整的方式,同样适...

Abstract

The invention discloses a multi-screen display method, which comprises the steps of: a controller acquires the viewpoint angles of each display screen and the user; transforms an image according to the viewpoint angle, and sends the converted image to a display screen corresponding to the viewpoint angle for display . The present invention transforms the image adaptively to the angle of view, and transmits the transformed image to the display screen for display to the user, ensuring that the image displayed on each display screen is closer to the user's viewing angle, making the image more real, It effectively solves the problem of unsatisfactory display effect caused by the viewing angle; especially for three-dimensional display, it can achieve a realistic and peculiar display effect; the present invention can be realized only by installing a low-cost angle sensor, and does not need to increase Other hardware devices are economical and practical; and no additional operations are required by the user, which is very convenient. The invention also discloses a multi-screen display system.

Description

technical field [0001] The invention relates to the technical fields of graphics processing and multi-screen display, in particular to a multi-screen display method and system. Background technique [0002] When people watch images on a display screen, they hope to obtain a wide visual effect. One method is to increase the size of a single display screen, which increases the price of the display screen, and the huge display screen is not conducive to moving and carrying, especially for LCD (Liquid Crystal Display, liquid crystal display) screens. , it is also difficult to achieve from a technical point of view; another way is to use multi-screen display, which is becoming more and more common, and can bring users a wide field of view and more display content, and the active connection between each display screen, It can be folded and carried, very convenient. [0003] In the current multi-screen display, it is mainly applied in two aspects: [0004] One is that each displ...
