圖像識(shí)別說(shuō)白了就是把一張照片上面的文字進(jìn)行提取，提供工作效率
需求分析
身份證識(shí)別主要是把一張身份證照片上面的文字信息進(jìn)行提取，不用再使用人工去手動(dòng)抄寫(xiě)了，下面給大家說(shuō)的這個(gè)身份識(shí)別主要是使用python+flask+華為云OCR進(jìn)行實(shí)現(xiàn)的。
步驟
- 申請(qǐng)華為云OCR接口
- 獲取token
- 調(diào)用身份證識(shí)別接口
- 提取身份證信息
申請(qǐng)華為云OCR接口
圖像識(shí)別主要使用的就是華為云OCR平臺(tái)申請(qǐng)的接口，申請(qǐng)地址為：“https://www.huaweicloud.com”。訪問(wèn)申請(qǐng)的地址后點(diǎn)擊菜單欄中的“控制臺(tái)”，點(diǎn)擊后會(huì)進(jìn)入登錄頁(yè)面。
登錄成功后進(jìn)入控制臺(tái)，依次單擊“服務(wù)列表”-“人工智能”-“文字識(shí)別OCR”
進(jìn)入后點(diǎn)擊身份證識(shí)別后面的“開(kāi)通服務(wù)”即可，（這里需要主要的是免費(fèi)開(kāi)通的身份證識(shí)別服務(wù)僅有1000次的免費(fèi)調(diào)用次數(shù)，超過(guò)次數(shù)將會(huì)收費(fèi)，建議購(gòu)買(mǎi)套餐包，購(gòu)買(mǎi)可以找我，我可以給優(yōu)惠哦）
獲取token
獲取token值時(shí)你需要知道你的以下信息：
- IAM用戶所屬賬號(hào)名
- IAM用戶名
- IAM用戶的登錄密碼
- IAM用戶所屬賬號(hào)的項(xiàng)目名稱
首先就是獲取IAM用戶所屬賬號(hào)名，IAM用戶所屬賬號(hào)名為你登陸的那個(gè)賬號(hào)
獲取IAM用戶名，選擇右上角“用戶名”-點(diǎn)擊“統(tǒng)一身份認(rèn)證”
里面的用戶即為IAM用戶名
獲取IAM用戶所屬賬號(hào)的項(xiàng)目名稱，點(diǎn)擊“項(xiàng)目”
里面的項(xiàng)目很多，你只需要記錄你開(kāi)啟OCR身份證識(shí)別區(qū)域的項(xiàng)目名稱ID就可以了，比如我選擇的北京四所以我的項(xiàng)目名稱就是：“cn-north-4”
知道了這些信息之后，后面就是如何通過(guò)這些信息去獲取token了，下面我就直接上代碼了哦
import requests
# 下面url為華為云獲取token的接口，這個(gè)接口基本一致，需要注意的是“iam.cn-north-4.myhuaweicloud.com”這個(gè)需要根據(jù)具體需求進(jìn)行修改，不同區(qū)域項(xiàng)目不同
url = "https://iam.cn-north-4.myhuaweicloud.com/v3/auth/tokens"
# 頭部信息
headers = {'Content-Type': 'application/json'}
# json內(nèi)容，需要上傳進(jìn)行做驗(yàn)證
payload = {
"auth": {
"identity": {
"methods": [
"password"
],
"password": {
"user": {
# name值為你的IAM賬號(hào)名
"name": "XXX",
# password值為你的IAM密碼
"password": "XXX",
"domain": {
# name值為你的主賬號(hào)的賬號(hào)名
"name": "XXX"
}
}
}
},
"scope": {
"project": {
# name值為你的項(xiàng)目ID
"name": "cn-north-4"
}
}
}
}
# 使用POST上傳頭部?jī)?nèi)容和body內(nèi)容
response = requests.post(url, headers=headers, json=payload)
# 獲取token值
token = response.headers['X-Subject-Token']
# 打印token值
print(token)
打印出來(lái)的值是類似于下面這種的字符串

調(diào)用身份證識(shí)別接口
下面就是調(diào)用識(shí)別接口，調(diào)用這個(gè)接口需要了解以下信息
- URL
- Header參數(shù)
- Body參數(shù)
首先是URL
POST https://{endpoint}/v2/{project_id}/ocr/id-card
| 參數(shù) |
說(shuō)明 |
| endpoint |
項(xiàng)目接口域名，這里還是需要確定開(kāi)通服務(wù)的區(qū)域，每個(gè)區(qū)域不同的域名 |
| project_id |
項(xiàng)目ID，不出意外的話就是你上面獲取token的項(xiàng)目ID |
|
請(qǐng)求參數(shù)
請(qǐng)求Header參數(shù)
| 參數(shù) |
說(shuō)明 |
| X-Auth-Token |
用戶Token，就是上面獲取到的token值 |
| Content-Type |
發(fā)送的實(shí)體的MIME類型，參數(shù)值為“application/json” |
|
請(qǐng)求Body參數(shù)
| 參數(shù) |
說(shuō)明 |
| image |
圖像數(shù)據(jù)，base64編碼，要求base64編碼后大小不超過(guò)10MB。圖片最小邊不小于15px，最長(zhǎng)邊不超過(guò)8000px。支持JPEG、JPG、PNG、BMP、TIFF格式。 |
| url |
圖片的url路徑 |
| side |
front：身份證人像面，back：身份證國(guó)徽面 |
了解了上面的一系列信息之后，后面就是如何寫(xiě)代碼了，下面就是直接代碼
import requests
import base64
# url值
url = https://{endpoint}/v2/{project_id}/ocr/id-card
# 上面獲取到的token值
token = ""
# 設(shè)置頭部信息
headers = {'Content-Type': 'application/json', 'X-Auth-Token': token}
# 圖片路徑
imagepath = r'./static/XXX.jpg'
# 設(shè)置圖片
with open(imagepath, "rb") as bin_data:
image_data = bin_data.read()
# 使用圖片的base64編碼
image_base64 = base64.b64encode(image_data).decode("utf-8")
# url與image參數(shù)二選一
payload = {"image": image_base64}
# 上傳參數(shù)
response = requests.post(url, headers=headers, json=payload)
# 打印識(shí)別的信息
response = response.text
print(response)
最后識(shí)別出來(lái)的結(jié)果類似于下面的信息：
{
"result": {
"name": "XXX",
"sex": "男",
"ethnicity": "漢",
"birth": "XXX",
"address": "XXX",
"number": "XXX"
}
}
如果想獲取其中的某一個(gè)值的話需要先轉(zhuǎn)換為字典，通過(guò)字典再進(jìn)行單一讀取
import json
# 轉(zhuǎn)換為字典
test = json.loads(response)
# 從字典中獲取相應(yīng)的值
username = test['result']['name']
到這里就已經(jīng)完成了這個(gè)項(xiàng)目
總結(jié)
上面已經(jīng)簡(jiǎn)單說(shuō)明了如何調(diào)用相應(yīng)的接口去識(shí)別身份證了，下面我把源碼給到大家吧，大家可以作為參考哦，下面是使用python+flask+redis+華為云OCR實(shí)現(xiàn)的
