數組轉換為圖片的方法

import numpy as np
import cv2 as cv
path_image_data = 'C:/Users/10107472/Desktop/my_yolo/data/image/'
image = np.zeros((5, 416, 416, 3))
print(image.shape)
for i in range(5):              # 讀取5張圖片
    a = str(i)
    b = cv.imread(path_image_data+a+'.bmp')
    b = cv.resize(b, (416, 416))
    image[i] = b  # 將圖片保存該矩陣中，這一步實際已經將值保存在了image中了
print(image.shape)
cv.imshow("original_image", image[2])
image=np.asanyarray(image,dtype=np.uint8)  # 關鍵 np.uint8 ，使其可以打印出圖片
cv.imshow('change_image', image[2])
cv.waitKey()
