图片转为字符串（蔡徐坤之舞动人生）

一、直接看效果

源代码图像：

结果图像（转为彩色字符串）：

2、上代码

解释：下面的path是视频路径，结果就会显示如上图所示；想要黑白效果自需要将代码下面的（b，g，r）改为（255，255，255）黑白的，具体代码里有注释

import cv2
import numpy as np
def readVideo(path):videoCapture = cv2.VideoCapture()videoCapture.open(path)frames = videoCapture.get(cv2.CAP_PROP_FRAME_COUNT)fps = videoCapture.get(cv2.CAP_PROP_FPS)for i in range(int (0),int(fps*10)):ret,frame = videoCapture.read()#     ret是bool类型，frame是image ndarray类型src = cv2.resize(frame,(int (frame.shape[1]*0.6),int (frame.shape[0]*0.6)))src = imageToChar(src)cv2.imshow('frame',src)cv2.waitKey(1)
#         cv2.destroyAllWindows()def imageToChar(img):   string = "&*qwertyuiopasdfghjklzxcvbnmQWERTYUIOPASDFGHJKLZXCVBNM"count = len(string)u, v, _= img.shapec = img*0 + 0# c = np.zeros((u,v))gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)# cv2.imshow('output', c)for i in range(0, u-1,10):for j in range(0, v-1,10):pix = gray[i, j]b, g, r = img[i, j]zifu = string[int(((count - 1) * pix) / 256)]cv2.putText(c, zifu, (j, i), cv2.FONT_HERSHEY_COMPLEX, 0.5,(int(b),int(g),int(r)))
#     想要将图像转化为黑白的只需要把(int(b),int(g),int(r))改成（0，255，255）return c
readVideo('../image/cai.mp4')
cv2.waitKey(0)
