以下结合附图与具体实施例进一步阐述本发明的优点。
实施例一
如图1所示，为符合本发明实施例中的一种基于智能终端，如手机、平板电脑等设
备的证件照片生成方法的流程示意图。所述证件照片生成方法包括如下步骤：
启动所述智能终端的照相模块，显示一设有人像框的参照图像；
打开智能终端，在智能终端的操作界面上找到拍摄应用程序的图标，点击该图标，打开拍摄应用程序，启动智能终端中的照相模块，启动后，智能终端的操作界面上会显示一设有人像框的参照图像。
优选地，所述参照图像还包括证件照片类型、尺寸、背景颜色、像素中的一种或多种。
智能终端的操作界面上显示出一设有人像框的参照图像，其中，该参照图像进一步包含证件照片的类型(如：签证、驾驶证、结婚证、护照等)、证件照片的尺寸(如：1寸、2寸等)、证件照片的背景颜色(如：白色、蓝色、红色等)及证件照片的像素(如：413像素*295像素、390像素*260像素、626像素*413像素等)等拍摄要求。不同的证件照片类型对应的是不同种类的证件照片尺寸、背景颜色、像素等拍摄要求。例如，对于某个国家的签证照片而言，智能终端会根据该国签证照片的要求，包括照片尺寸大小、照片背景颜色、像素、拍摄要求等信息显示出一参照图像，并且该参照图像中进一步包含一人像框，供用户拍摄时参照。
采集一人像图像；
当智能终端显示出一设有人像框的参照图像后，用户可以开始采集一人像图像。该采集过程既可以由智能终端的前置摄像头完成，也可以由智能终端的后置摄像头完成。基于证件照片的拍摄要求，该人像图像一般为半身像，被拍摄人的免冠(不戴帽子)正面照。
提取所述人像图像中的预览人像，并获取所述预览人像的人像轮廓；
当智能终端采集到被拍摄人的人像图像后，提取该人像图像的预览人像，即可以在智能终端中的参照图像上看到动态的被拍摄人的人像时，进一步地，智能终端可以获取到该预览人像的人像轮廓。
匹配所述人像轮廓及人像框，将所述预览人像叠合至所述人像框内，生成一证件照片。
待智能终端获取到预览人像的人像轮廓后，可以对该人像轮廓与参照图像中提供的人像框进行比较。判断被拍摄人的人像轮廓是否与参照图像中提供的人像框重合，即被拍摄人是否处于参照图像中显示出的人像框中，该人像框为符合参照图像对应的证件照片拍摄要求的位置。该人像框不仅能够为用户提供参考位置，更能提高证件照片的合格率。例如，在某些国家签证办理时会对签证照片中人像的头部位置和肩部位置进行进一步地限定，对于这种要求，本发明实施例中的人像框就能起到很好的参照作用，避免产生用户拍摄的证件照片不满足某些证件照片要求的问题。
当智能终端判断被拍摄人的人像轮廓与参照图像中设定的人像框重合时，即被拍摄人的人像轮廓符合该类证件照片中人像所在位置时，用户按下快门，智能终端即可自行将人像轮廓所对应的预览人像叠合至参照图像的人像框内，此时，智能终端的界面上显示一叠合而成的证件照片。

获取到的人像轮廓尺寸变小。当人像轮廓过大时，用户可以选择减少被拍摄人与智能终端摄像头的距离，使得智能终端获取到的人像轮廓尺寸变大。待完成调整人像轮廓的尺寸后，智能终端进一步获取人像轮廓与人像框的重合度，当获取到的重合度大于等于90％时，智能终端判定人像轮廓与人像框匹配。
优选地，当所述重合度小于90％时，所述人像轮廓与所述人像框不匹配，匹配所述人像轮廓及人像框的步骤进一步包括根据所述人像框微调所述人像轮廓；所述微调包括平移、缩放、填充、剪裁中的一种或多种。
待完成调整人像轮廓的尺寸后，智能终端进一步获取人像轮廓与人像框的重合度，当获取到的重合度小于90％时，智能终端判定人像轮廓与人像框不匹配。此时智能终端对人像轮廓会进行自动微调。该微调能够增加人像轮廓与人像框的重合度到90％以上，例如：平移、缩放、填充、剪裁等等。如：将人像轮廓向与人像框重合的方向平移；通过缩小或放大人像轮廓提高其与人像框的重合度；采用背景颜色填充人像轮廓与人像框的中空部分；剪裁不必要的多余部分等。
