在裁剪的图像上使用pytesseract

Question

我正在裁剪图像，然后在其上使用pytesseract从中读取数字。但是，我必须首先保存裁剪的图像，然后再次加载它以使此代码起作用。有没有办法可以避免这样做并提高效率？如果我将cropped直接传递给image_to_string，则会崩溃：

in image_to_string if len(image.split()) == 4: AttributeError: 'numpy.ndarray' object has no attribute 'split'

cropped = image[1044:2000, 100:1025]
cv2.imwrite("thumbnail.png", cropped)
img = Image.open("thumbnail.png")
print(pytesseract.image_to_string(img, config='-psm 6'))
print("--- %s seconds ---" % (time.time() - start_time))

Answer 1

使用Image.fromarray()

cropped = image[1044:2000, 100:1025] img = Image.fromarray(cropped) print(pytesseract.image_to_string(img, config='-psm 6')) print("--- %s seconds ---" % (time.time() - start_time))
