我有旋转文本的图像。我正在获取此文本的位置并将其裁剪,然后旋转此文本。到此为止,我可以看到文字完美显示。但是现在,如果我将旋转后的文本发送到“pytesseract.image_to_string”,则无法识别该文本。这是代码。
croped = orig[y:y+h, x:x+w].copy()
cv2.imshow('cropped ',croped)
text_img = cv2.cvtColor(croped, cv2.COLOR_BGR2GRAY)
text_img_nt = cv2.bitwise_not(text_img)
cv2.imshow('text img not ',text_img_nt)
thresh = cv2.threshold(text_img_nt, 0, 255,cv2.THRESH_BINARY | cv2.THRESH_OTSU)[1]
coords = np.column_stack(np.where(thresh > 0))
angle = cv2.minAreaRect(coords)[-1]
if angle < -45:
angle = -(90 + angle)
else:
angle = -angle
(h, w) = text_img_nt.shape[:2]
center = (w // 2, h // 2)
M = cv2.getRotationMatrix2D(center, angle, 1.0)
rotated = cv2.warpAffine(text_img_nt, M, (w, h),flags=cv2.INTER_CUBIC, borderMode=cv2.BORDER_REPLICATE)
cv2.imshow('rotated',rotated)
cv2.waitKey(100000)
config='-l eng --oem 1 --psm 3'
textRecognized = pytesseract.image_to_string(rotated, config = config, lang ='eng')
print(textRecognized)
Cropped ImageRotated Image
识别的文本:“Ol Ey”
我的代码有什么问题吗?任何帮助都感激不尽。

关于python-3.x - 无法使用pytesseract.image_to_string识别单词,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/64038556/
