Paddle打比赛】基于PaddleOCR的AIWIN手写体识别
使用PaddleOCR的 CRNN+CTC对大写金额数字、日期数字进行识别。
·
一、【Paddle打比赛】AIWIN 手写体OCR识别竞赛
1.赛题背景
http://ailab.aiwin.org.cn/competitions/65#learn_the_details
银行日常业务中涉及到各类凭证的识别录入，例如身份证录入、支票录入、对账单录入等。以往的录入方式主要是以人工录入为主，效率较低，人力成本较高。近几年来，OCR相关技术以其自动执行、人为干预较少等特点正逐步替代传统的人工录入方式。但OCR技术在实际应用中也存在一些问题，在各类凭证字段的识别中，手写体由于其字体差异性大、字数不固定、语义关联性较低、凭证背景干扰等原因，导致OCR识别率准确率不高，需要大量人工校正，对日常的银行录入业务造成了一定的影响。
2. 赛题任务
本次赛题将提供手写体图像切片数据集，数据集从真实业务场景中，经过切片脱敏得到，参赛队伍通过识别技术，获得对应的识别结果。即：
输入：手写体图像切片数据集
输出：对应的识别结果
赛题在赛程中分设为两个独立任务，各自设定不同条件的训练集、测试集和建模环境，概述如下：
- 任务一：提供开放可下载的训练集及测试集，允许线下建模或线上提供 Notebook 环境及 Terminal 容器环境（脱网）建模，输出识别结果完成赛题。
- 任务二：提供不可下载的训练集，要求线上通过 Terminal 容器环境（脱网）建模后提交模型，由系统输入测试集（即对选手不可见），输出识别结果完成赛题。
3.数据基本情况
|
| 任务一 | 任务二 |
| 训练集（含验证集，请自行划分） | 8 千张图像，包含年份、金额2种信息 | 3 万张图像，包含银行名称、年份、月份、日期、金额5 种信息。 |
| 测试集 | 2 千张图像 | 设定 AB榜： A 榜：5 千张图像 B 榜：5 千张图像 |
原始手写体图像共分为三类，分别涉及银行名称、年月日、金额三大类，分别示意如下：
相应图片切片中可能混杂有一定量的干扰信息，分别示例如下；
二、环境设置
PaddleOCR https://github.com/paddlepaddle/PaddleOCR 是一款全宇宙最强的用的OCR工具库，开箱即用，速度杠杠的。
# 从gitee上下载PaddleOCR代码，也可以从GitHub链接下载
!git clone https://gitee.com/paddlepaddle/PaddleOCR.git --depth=1
# 升级pip
!pip install -U pip
# 安装依赖
%cd ~/PaddleOCR
%pip install -r requirements.txt
三、数据准备
主要任务有：
- 数据解压缩
- det数据集格式化和数据集划分
- rec数据集格式化和数据集划分
# 解压缩
%cd ~
!unzip -qoa 2021A_T1_Task1_数据集含训练集和测试集.zip
