英文:
Crash when reading bit map image in python
问题
使用以下代码块，我正在尝试读取并存储一个BMP图像，以便使用匹配算法进行图像处理。
print("starting read image function")
fimage = glob.glob("test.bmp")
incomingFingerprint = cv2.imread(fimage)
cv2.imwrite(fimage.replace('.bmp', '.jpg'), incomingFingerprint)
我发现我的代码崩溃，并在终端中打印了以下行：
进程以退出码 -1073740791 (0xC0000409) 结束
我想成功地读取并将图像存储在一个变量中，然后应用一些图像处理算法。
英文:
Using the following code block, I am trying to read and store a bmp image in order to make some image processing using a matching algorithm.
print("starting read image function")
fimage = glob.glob("test.bmp")
incomingFingerprint = cv2.imread(fimage)
cv2.imwrite(fimage.replace('.bmp', '.jpg'), incomingFingerprint)
I got my code crashed and printed this line in the terminal:
Process finished with exit code -1073740791 (0xC0000409)
I want to successfully read and store an image in a variable and then apply some image processing algorithms.

你错误地使用了 glob — 它在输出时会给你一个列表。相反，只需将图像名称传递给 imread 和 imwrite 函数：
import cv2
incoming_fingerprint = cv2.imread('test.bmp')
cv2.imwrite('test.jpg', incoming_fingerprint)
英文:
You're incorrectly using glob — it gives you a list on output. Instead, simply pass image name to the imread and imwrite functions:
import cv2
incoming_fingerprint = cv2.imread('test.bmp')
cv2.imwrite('test.jpg', incoming_fingerprint)
