Python+OpenCv制作证件图片生成器的操作方法
作者：不脱发的程序猿
这篇文章主要介绍了Python+OpenCv制作证件图片生成器的操作方法，本文通过实例代码给大家介绍的非常详细，具有一定的参考借鉴价值,需要的朋友可以参考下
本项目使用Python和OpenCv实现身份证图片生成工具，填入信息，选择一张头像图片（即可生成黑白和彩色身份证图片）。可以选择是否自动抠图，自动抠图目前仅支持蓝色背景，对自动抠图效果不满意可以手动抠图。
在线抠图地址:
参照标准：
正面
“姓名”、“性别”、“民族”、“出生年月日”、“住址”、“公民身份号码”为6号黑体字，用蓝色油墨印刷；登记项目中的姓名项用5号黑体字印刷；其他项目则用小5号黑体字印刷；出生年月日 方正黑体简体字符大小：姓名＋号码（11点）其他（9点）字符间距（AV）：号码（50）字符行距：住址（12点）；身份证号码字体 OCR-B 10 BT 文字 华文细黑。
背面
左上角为国徽，用红色油墨印刷;其右侧为证件名称“中华人民共和国居民身份证”，分上下两排排列，其中上排的“中华人民共和国”为4号宋体字，下排的“居民身份证”为2号宋体字;“签发机关”、“有效期限”为6号加粗黑体字;签发机关登记项采用，“xx市公安局”;有效期限采用“xxxx.xx-xxxx.xx.xx”格式，使用5号黑体字印刷，全部用黑色油墨印刷。
这里我用周杰伦的图像制作简单的身份证图片，效果图如下：
实现Demo如下：

# 获取mask
lower_blue = np.array([78, 43, 46])
upper_blue = np.array([110, 255, 255])
mask = cv2.inRange(hsv, lower_blue, upper_blue)
# cv2.imshow('Mask', mask)
# 腐蚀膨胀

dilate = cv2.dilate(erode, None, iterations=1)
# 粘贴
for i in range(rows):
for j in range(cols):
if dilate[i, j] == 0: # 0代表黑色的点
img_back[center[0] + i, center[1] + j] = img[i, j] # 此处替换颜色，为BGR通道
return img_back

之前上传代码使用项目命名：“Python+OpenCv制作身份证图片生成器代码”，额、但是官方宣布违规禁止上传，所示将项目名称修改的不是那么明显，感兴趣的小伙伴可以下载运行：

当然为了方便操作，也可以使用pyinstaller模块自己打包成应用程序，首先需要使用命令安装pyinstaller模块：
pip install pyinstaller
Mac打包(打包成Mac app尚有问题未解决)
pyinstaller -i usedres/ico.icns --windowed --clean --noconfirm --onefile --add-data ./usedres:./usedres idcardgenerator.py
Windows打包
pyinstaller -i usedres/ico.ico --windowed --clean --noconfirm --onefile --add-data usedres;usedres idcardgenerator.py
