本申请提供一种基于大屏创建全景图片的方法、装置、智能终端及介质,为使本申请的目的、技术方案及效果更加清楚、明确,以下参照附图并举实施例对本申请进一步详细说明。应当理解,此处所描述的具体实施例仅用以解释本申请,并不用于限定本申请。

下面结合附图以及具体实施例对本申请的技术方案加以说明,如下:
请参阅图1,图1为一种基于大屏创建全景图片的方法的流程图。应该说明的是,本发明实施方式的基于大屏创建全景图片的方法并不限于图1所示的流程图中的步骤及顺序,根据不同的需求,流程图中的步骤可以增加、移除或者改变顺序。如图1所示,基于大屏创建全景图片的方法包括:
S10、系统获取目标图片的图片分辨率和大屏的屏幕分辨率。
具体地,目标图片指的是需要合成为全景图的对象。在本实施例中该目标图片为标清图片,即目标图片的图片分辨率为标清分辨率,该标清分辨率通常为480p(720×480像素分辨率等)或 576p ,用度SD(Standard Definition)表示标清分辨率。
需要说明的是,如480p中480指的是垂直分辨率,垂直方向有480条水平线的扫描线。
目标图片可来源于网络,也可来源于拍摄。因此,为了提高合成全景图的质量,可对目标图片进行预处理操作。该预处理操作指的是根据用户需求所设定的处理规则,如对目标图片进行亮度增强处理,或对目标图片进行裁剪处理等。该处理规则并非限定的,可根据不同场景进行自由设定。
大屏指的是显示屏的屏幕对角线尺寸大于40英尺以上。例如:直观式彩电或背投式投影电视中的大屏幕。因此,大屏的屏幕分辨率可以是高清分辨率HD(High Definition),720p(1280×720像素分辨率) ;可以是全高清分辨率FHD(Full High Definition),1080p(1080×720像素分辨率) ;可以是超高清分辨率UHD(Ultra High Definition),4k (4096×2160像素分辨率);还可以是全超高清分辨率FUHD(Full Ultra High Definition),8k (7680×4320像素分辨率,16:9)。
具体地,系统获取目标图片的图片分辨率和大屏的屏幕分辨率具体包括:
S11,当监测到智能终端发送目标图片的命令时,系统接收目标图片并获取目标图片的图片分辨率;图片分辨率表示为目标图片的水平像素数*垂直像素数;
S12,系统获取大屏的屏幕分辨率;屏幕分辨率表示为大屏的水平像素数*垂直像素数。
在本实施例中,若大屏的屏幕分辨率为1080p(1920*1080),1920表示为水平像素数,1080表示为垂直像素数,目标图片的图片分辨率为720*640,其中,720表示为水平像素数,640表示为垂直像素数。
S20、系统计算图片分辨率和屏幕分辨率的分辨率差值,根据分辨率差值对目标图片进行调整,得到与屏幕分辨率匹配的大屏图。
具体地,由于图片分辨率和屏幕分辨率均包括水平像素数和垂直像素值,因此,计算图片分辨率和屏幕分辨率的分辨率差值表示为计算图片分辨率中水平像素数与屏幕分辨率中水平像素数的分辨率差值以及图片分辨率中垂直像素数与屏幕分辨率中垂直像素数的分辨率差值。在本实施例中,以计算图片分辨率中水平像素数与屏幕分辨率中水平像素数的分辨率差值为调整分辨率比例。
进一步地,将图片分辨率中的水平像素数与屏幕分辨率中的水平像素数作差,得到水平分辨率差值。由于屏幕分辨率大于或等于图片分辨率,因此,获取水平分辨率差值的绝对值。
若水平分辨率差值的绝对值等于0,则将目标图片作为与屏幕分辨率匹配的大屏图。也就是说,目标图片的图片分辨率与大屏的屏幕分辨率相同,因此,无需对目标图片进行填充操作。
若水平分辨率差值的绝对值不等于0,则将水平分辨率差值的绝对值作为目标图片的水平方向上待填充像素个数。
例如:
目标图片Pic_X(x1) = 640//水平方向640水平像素;
大屏_XDisplay(x1) = 1080//大屏物理显示分辨率;
水平分辨率差值Dis_ChaRu(x1) = | 大屏_XDisplay(x1) - Pic_X(x1) |=1080-640=440,440即为水平分辨率差值,将440作为目标图片的水平方向上待填充像素个数。
在填充过程中,需要预先确定待填充颜色,在获取了待填充颜色的颜色像素值后利用该颜色像素值对目标图片进行填充,以使得填充目标图片后得到的大屏图的图片分辨率与大屏的屏幕分辨率相同、匹配。
具体地,系统确定待填充颜色,并获取待填充颜色对应的颜色像素值的过程为:
S211,获取目标图片上各填充色的颜色像素值及各填充色对应的像素个数;各填充色的颜色像素值均包括R值、G值以及B值;
S212,根据各填充色的第一颜色像素值及各填充色对应的像素个数分别计算R值、G值以及B值的平均值,得到R均值、G均值以及B均值;
S213,确定R均值、G均值以及B均值对应的颜色,该颜色为待填充颜色,待填充颜色的颜色像素值为R均值、G均值以及B均值。
可以理解的是,目标图片上填充色的颜色像素值均包括RGB值,因此,利用均值像素筛选,以筛选出目标图片上红色、绿色以及蓝色中出现颜色最多的颜色,将该颜色作为待填充颜色,其颜色像素值即为各RGB均值。
例如:
Ave_PixeRGB(r1,g1,b1) ={“0”,“128”,“255”}//平均值为填充蓝色的像素。
在确定了待填充颜色后,对目标图片进行填充,填充至填充个数达到待填充像素个数如440时停止填充,获取此时停止填充对应的大屏图。这样,填充后得到的大屏图的图片分辨率与屏幕分辨率相同。
S30、系统创建置于大屏图上的悬浮窗图层,并在悬浮窗图层上通过预设算法配置和填充屏幕分辨率所属类别对应的平移拓展区域以及感兴直视区域;其中,平移拓展区域用于将目标图片通过平移操作和拓展操作转化为大屏图;感兴直视区域用于将大屏图通过视差转化为全景图。
S40、系统分别设定平移拓展区域和感兴直视区域所对应的悬浮窗图层的图层透明度。
在本实施例中,屏幕分辨率所属类别分为两类,高清分辨率和超高清分辨率。因此,针对这两类,分别创建对应的平移拓展区域以及感兴直视区域。其中,该平移拓展区域可看成将目标图片投射至大屏进行无缝连接。该感兴直视区域可看成目标图片投射后形成的视差。
(一)、若屏幕分辨率所属类别为高清分辨率,创建置于大屏图上的悬浮窗图层,并在悬浮窗图层上通过预设算法配置和填充屏幕分辨率所属类别对应的平移拓展区域以及感兴直视区域,包括:
S311,根据屏幕分辨率创建悬浮窗图层,以使得悬浮窗图层的大小与大屏相匹配;
S312,将悬浮窗图层置于大屏图上端;
S313,通过预设的平移拓展区域算法根据目标图片在悬浮窗图层上配置第一平移拓展区域;
S314,从水平方向截取目标图片上第一水平比例(如3/4)的第一水平像素;
S315,将第一水平像素填充至第一平移拓展区域;
S316,填充完第一平移拓展区域后增加预设的感兴直视算法,以得到第一感兴直视区域;其中,第一平移拓展区域包括第一感兴直视区域;
S317,截取目标图片中垂直方向上第一垂直比例(如1/2)的第一垂直像素;
S318,将第一垂直像素填充至第一感兴直视区域。
系统分别设定平移拓展区域和感兴直视区域所对应的悬浮窗图层的图层透明度包括:
S411,配置第一感兴直视区域所对应的悬浮窗图层的图层透明度为全透明;
S412,配置第一感兴直视区域所对应的悬浮窗图层的图层透明度为全透明。
具体地,如下表1,若屏幕分辨率为1080p,则目标图片的图片分辨率如为720*640,则选取第一水平比例如3/4截取目标图片水平方向像素,3*720/4=540,此时,截取每条水平线上540个像素,获取每条水平线上所截取的像素长度配置第一平移拓展区域FOV resolution,具体为第一平移拓展区域的长度为540。通过平移拓展算法截取目标图片上每条水平线上540像素填充第一平移拓展区域,并配置该第一平移拓展区域所对应的悬浮窗图层从左到右的图层透明度为半透明即50%。
需要说明的是,第一感兴直视区域是根据悬浮窗图层的第一平移拓展区域而配置。因此,在第一平移拓展区域填充且配置完成后,对最终的第一平移拓展区域从左到右添加感兴直视算法,得到第一感兴直视区域。选取第一垂直比例如1/2截取目标图片垂直方向像素,1*640/2=320,此时,截图目标图片上每条垂直线上320像素,填充至第一感兴直视区域ROI resolution,并设置第一感谢直视区域所对应的悬浮窗图层的图层透明度为全透明即100%。
(二)、若屏幕分辨率所属类别为超高清分辨率,创建置于大屏图上的悬浮窗图层,并在悬浮窗图层上通过预设算法配置和填充屏幕分辨率所属类别对应的平移拓展区域以及感兴直视区域,包括:
S321,根据屏幕分辨率创建悬浮窗图层,以使得悬浮窗图层的大小与大屏相匹配;
S322,将悬浮窗图层置于大屏图上端;
S323,计算目标图片的高清分辨率对应的高清图片;其中,高清图片的图片分辨率大于目标图片的图片分辨率;
S324,通过预设的平移拓展区域算法根据高清图片在悬浮窗图层上配置第二平移拓展区域;
S325,从水平方向截取高清图片上第二水平比例的第二水平像素;
S326,将第二水平像素填充至第二平移拓展区域;
S327,填充完第二平移拓展区域后增加预设的感兴直视算法,得到第二感兴直视区域;其中,第二平移拓展区域包括第二感兴直视区域;
S328,截取高清图片中垂直方向上第二垂直比例的第二垂直像素;
S329,将第二垂直像素填充至第二感兴直视区域。
分别设定平移拓展区域和感兴直视区域所对应的悬浮窗图层的图层透明度包括:
S421,配置第二平移拓展区域所对应的悬浮窗图层的图层透明度为半透明;
S422,配置第二感兴直视区域所对应的悬浮窗图层的图层透明度为全透明。
具体地,如下表1,若屏幕分辨率为3840p,则目标图片的图片分辨率如为720*640,需要将目标图片转换为高清图片,再有高清图片转换为超高清图片即大屏图。具体为计算目标图片的高清分辨率对应的高清图片;高清图片的图片分辨率大于目标图片的图片分辨率。即该高清图片可为上述(一)中大屏图。
选取第二水平比例如4/3截取高清图片水平方向像素,4*1080/3=1440,此时,截取每条水平线上1440个像素,获取每条水平线上所截取的像素长度配置第二平移拓展区域FOV resolution,具体为第二平移拓展区域的长度为1440。通过平移拓展算法截取高清图片上每条水平线上1440像素填充第二平移拓展区域,并配置该第二平移拓展区域所对应的悬浮窗图层从左到右的图层透明度为半透明即50%。
需要说明的是,第二感兴直视区域是根据悬浮窗图层的第二平移拓展区域而配置。因此,在第二平移拓展区域填充且配置完成后,对最终的第二平移拓展区域从左到右添加感兴直视算法,得到第二感兴直视区域。选取第二垂直比例如3/4截取高清图片垂直方向像素,3*720/4=540,此时,截图高清图片上每条垂直线上540像素,填充至第二感兴直视区域ROI resolution,并设置第二感谢直视区域所对应的悬浮窗图层的图层透明度为全透明即100%。

S50、系统将不同图层透明度的悬浮窗图层与大屏合成,得到目标图片的全景图。
具体地,针对步骤S30、S40中所屏幕分辨率不同,利用将不同图层透明度的悬浮窗图层与大屏合成,得到目标图片的不同分辨率的全景图。具体为:屏幕分辨率所属类别为高清分辨率,利用无缝叠加技术,将不同图层透明度的悬浮窗图层与大屏合成,得到目标图片的高清全景图;屏幕分辨率所属类别为超高清分辨率,利用无缝叠加技术,将不同图层透明度的悬浮窗图层与大屏合成,得到目标图片的超高清全景图。
这样,基于步骤S10-S50,本申请利用分辨率差值将目标图片生成与屏幕分辨率匹配的大屏图(即平面全景图),然后通过悬浮窗图层的不同图层透明度、平移拓展区域算法和感兴直视算法以及无缝叠加技术,使得该大屏图转化为三维全景图,从而将智能大屏与VR技术相结合,使得智能大屏也能提供360°全景图,提高用户视觉感受,扩大推广,方便用户。
