Python拍照加时间戳水印

本程序实现经过笔记本摄像头拍照，而后在照片的右下角处加入时间戳的水印，分为2个函数分别实现拍照和加时间戳水印。用的时候本身先把须要的库都安装了，如下代码在Win七、Python3.6里调试经过__author__ = 'Yue Qingxuan'# -*- coding: utf-8 -*-import cv2import timeimport osfrom PIL import Image, ImageDraw, ImageFontdef TakePhoto(path):    cap = cv2.VideoCapture(0)    while(1):        # get a frame        ret, frame = cap.read()        # show a frame        cv2.imshow("Capture", frame)        if cv2.waitKey(1) & 0xFF == ord('q'):  #按字母q退出            timestr=time.strftime('%Y%m%d%H%M%S', time.localtime(time.time()))            filename=path+'/{0}.jpeg'.format(timestr)   #取当前时间做为照片的文件名            cv2.imwrite(filename, frame)            add_watermark(filename)            break    cap.release()    cv2.destroyAllWindows()def add_watermark(img_file):    # 建立绘画对象    image = Image.open(img_file)    draw = ImageDraw.Draw(image)    myfont = ImageFont.truetype('C:/windows/fonts/Arial.ttf',size=20)    fillcolor = '#ff0000'   #RGB红色    timestr=time.strftime('%Y-%m-%d %H:%M:%S', time.localtime(time.time()))  #格式化时间    width,height = image.size    # 参数一：位置（x轴，y轴）；参数二：填写内容；参数三：字体；参数四：颜色        draw.text((width - 200, height-35), timestr, font=myfont, fill=fillcolor)    image.save(img_file)if __name__ == '__main__':    path="E:/OpencvVideo"    if os.path.exists(path)==False:        os.makedirs(path)  #若是不存在就新建一个目录    TakePhoto(path)
