提取出票日期

def text1(new_img):
#提取出票日期
left = 80
top = 143
right = 162
bottom = 162
image_text1 = new_img.crop((left, top, right, bottom))
#展示图片
#image_text1.show()
txt1 = tool.image_to_string(image_text1)
print(txt1)
return str(txt1)

提取金额

def text2(new_img):
#提取金额
left = 224
top = 355
right = 585
bottom = 380
image_text2 = new_img.crop((left, top, right, bottom))
#展示图片
#image_text2.show()
image_text2.save("img/tmp.png")
temp = ocr.ocr("img/tmp.png")
temp="".join(temp[0])
txt2=chineseNumber2Int(temp)
print(txt2)
return txt2

提取出票人

def text3(new_img):
#提取出票人
left = 177
top = 207
right = 506
bottom = 231
image_text3 = new_img.crop((left, top, right, bottom))
#展示图片
#image_text3.show()
image_text3.save("img/tmp.png")
temp = ocr.ocr("img/tmp.png")
txt3="".join(temp[0])
print(txt3)
return txt3

提取付款行

def text4(new_img):
#提取付款行
left = 177
top = 274
right = 492
bottom = 311
image_text4 = new_img.crop((left, top, right, bottom))
#展示图片
#image_text4.show()
image_text4.save("img/tmp.png")
temp = ocr.ocr("img/tmp.png")
txt4="".join(temp[0])
print(txt4)
return txt4

提取汇票到账日期

def text5(new_img):
#提取汇票到日期
left = 92
top = 166
right = 176
bottom = 184
image_text5 = new_img.crop((left, top, right, bottom))
#展示图片
#image_text5.show()
txt5 = tool.image_to_string(image_text5)
print(txt5)
return txt5

提取票据单据

def text6(new_img):
#提取票据号码
left = 598
top = 166
right = 870
bottom = 182
image_text6 = new_img.crop((left, top, right, bottom))
#展示图片
#image_text6.show()
txt6 = tool.image_to_string(image_text6)
print(txt6)
return txt6
