--preprocessed results/predictions_conf01.txt \
|
||||
--output results/threshold_comparison.md
|
||||
|
||||
输入格式:
|
||||
识别结果文件应为制表符分隔的文本文件:
|
||||
```
|
||||
文件名 识别结果 置信度 数字个数
|
||||
YZM.jpeg 3809 0.584 4
|

|
||||
|
||||
输出示例:
|
||||
```markdown
|
||||
# 预处理效果对比报告
|
||||
|
||||
## 📊 整体统计
|
||||
| 指标 | 原始模型 | 预处理模型 | 改进 |
|
||||
|------|----------|------------|------|
|
||||
| 识别准确率 | 20.0% (3/15) | 80.0% (12/15) | +60.0% |
|
||||
| 平均置信度 | 0.512 | 0.653 | +0.141 |
|
||||
|
||||
## 🎯 改进案例
|
||||
预处理后新增识别正确的图片(9张):
|
||||
- **YZM-11.jpeg**: 53 (2位) → 5389 (4位) ✅
|
||||
...
|
||||
```
|
||||
|
||||
依赖环境:
|
||||
- Python 3.8+
|
||||
- 无第三方依赖(仅使用标准库)
|
||||
|
||||
注意事项:
|
||||
- 两个结果文件应该是在相同图片集上的识别结果
|
||||
- 文件名必须对应才能正确对比
|
||||
- 结果文件格式必须正确(制表符分隔)

YOLO数字识别 - 基础版本
|
||||
|
||||
功能说明:
|
||||
使用训练好的YOLO模型识别图片中的4位阿拉伯数字。
|
||||
这是基础版本,提供简单的数字检测和识别功能。
|
||||
|
||||
主要特性:
|
||||
- 批量处理图片文件夹
|
||||
- 支持自定义置信度阈值
|
||||
- 从左到右排序数字
|
||||
- 生成可视化结果(可选)
|
||||
- 输出识别结果到文本文件
|
||||
|
||||
算法流程:
|
||||
1. 加载YOLO模型
|
||||
2. 对每张图片进行目标检测
|
||||
3. 提取检测到的数字(0-9)
|
||||
4. 按x坐标从左到右排序
|
||||
5. 组合成完整数字串
|
||||
|
||||
适用场景:
|
||||
- 快速测试模型效果
|
||||
- 简单的数字识别任务
|
||||
- 作为改进版的基准对比
|
||||
|
||||
注意事项:
|
||||
- 不包含智能过滤,可能识别出非4位数字
|
||||
- 对于复杂场景建议使用 predict_digits_improved.py
|
||||
|
||||
使用示例:
|
||||
# 基础使用

YOLO数字识别 - 改进版本(推荐使用)
|
||||
|
||||
功能说明:
|
||||
在基础版本上添加了智能过滤和后处理逻辑,提高4位数字识别的准确率。
|
||||
这是生产环境推荐使用的版本。
|
||||
|
||||
主要特性:
|
||||
- 智能检测过滤(置信度、位置、尺寸)
|
||||
- 检测数量异常处理(<4或>4个数字)
|
||||
- 垂直位置对齐验证
|
||||
- 尺寸一致性检查
|
||||
- 自适应参数调整
|
||||
- 详细的识别质量报告
|
||||
|
||||
算法改进:
|
||||
1. 多级置信度过滤(基础阈值 + 动态调整)
|
||||
2. 位置异常检测(y坐标、尺寸统计分析)
|
||||
3. 数量控制(超过4个时选择最优组合)
|
||||
4. 数量不足时降低阈值重试(可选)
|
||||
|
||||
相比基础版的优势:
|
||||
✓ 更准确:智能过滤减少误检
|
||||
✓ 更稳定:处理各种异常情况
|
||||
✓ 更可靠:提供详细的质量指标
|
||||
✓ 更灵活:自适应不同图片质量
|
||||
|
||||
适用场景:
|
||||
- 生产环境的数字识别
|
||||
- 对准确率有要求的场景
|
||||
- 图片质量参差不齐的情况
|
||||
- 需要质量评估的应用
|
||||
|
||||
使用示例:
|
||||
# 使用最佳模型识别(推荐)
|
||||
python scripts/predict_digits_improved.py \
|
||||
--model runs/digit_yolo/exp_preprocessed_color_150/weights/best.pt \
|
||||
--source valid \
|
||||
--conf 0.2 \
|
||||
--save-vis
|
||||
|
||||
# 低置信度识别(图片模糊时)
|
||||
python scripts/predict_digits_improved.py --conf 0.15
|
||||
|
||||
# 高清识别
|
||||
python scripts/predict_digits_improved.py --imgsz 640
|
||||
|
||||
# 自定义输出
|
||||
python scripts/predict_digits_improved.py \
|
||||
--output results/my_predictions.txt
|
||||
|
||||
性能指标:
|
||||
- 识别速度: ~0.5s/张 (CPU M2)
|
||||
- 推荐置信度: 0.15-0.25
|
||||
- 最佳图片尺寸: 320 (速度) 或 640 (精度)

"""
|
||||
从YOLO预测结果中提取并智能处理数字
|
||||
|
||||
完整处理流程:
|
||||
1. 提取所有检测框的坐标、类别、置信度
|
||||
2. 调用filter_detections进行智能过滤
|
||||
3. 按x坐标从左到右排序(数字顺序)
|
||||
4. 根据检测数量采取不同策略:
|
||||
- 正好4个: 直接使用
|
||||
- 超过4个: 选择置信度最高的4个
|
||||
- 少于4个: 返回实际检测到的数字
|
||||
|
||||
智能选择策略:
|
||||
当检测超过4个时,不是简单按位置选择前4个,
|
||||
而是选择置信度最高的4个,这样可以过滤掉低质量检测。
|
||||
|
||||
Args:
|
||||
results: YOLO模型的预测结果对象

- results.boxes: 所有检测框信息

|
||||
- results.boxes.cls: 类别ID (0-9)
|
||||
- results.boxes.conf: 置信度
|
||||
img_width (int): 图片宽度,用于过滤时的参考
|
||||
img_height (int): 图片高度,用于过滤时的参考
|
||||
|
||||
Returns:

COCO到YOLO数据集转换工具
|
||||
|
||||
功能说明:
|
||||
将COCO格式的数字标注数据集转换为YOLO训练所需的格式。
|
||||
COCO格式使用JSON存储标注,YOLO格式使用文本文件存储。
|
||||
|
||||
主要功能:
|
||||
- 解析COCO格式的标注文件(coco.json)
|
||||
- 提取图片和边界框信息
|
||||
- 转换边界框格式:COCO [x,y,w,h] → YOLO [x_center,y_center,w,h] (归一化)
|
||||
- 自动划分训练集和验证集
|
||||
- 创建YOLO标准目录结构
|
||||
- 生成dataset.yaml配置文件
|
||||
|
||||
格式转换详解:
|
||||
COCO格式:
|
||||
- bbox: [x, y, width, height] (像素坐标,左上角)
|
||||
- 绝对坐标,单位为像素
|
||||
|
||||
YOLO格式:
|
||||
- bbox: [x_center, y_center, width, height] (归一化坐标)
|
||||
- 相对坐标,值在0-1之间
|
||||
- x_center = (x + width/2) / img_width
|
||||
- y_center = (y + height/2) / img_height
|
||||
|
||||
目录结构:
|
||||
输入(COCO格式):
|
||||
digit-validation/
|
||||
├── coco.json # 标注文件
|
||||
└── images/ # 图片文件
|
||||
|
||||
输出(YOLO格式):
|
||||
yolo_dataset/
|
||||
├── dataset.yaml # 配置文件
|
||||
├── images/
|
||||
│ ├── train/ # 训练集图片
|
||||
│ └── val/ # 验证集图片
|
||||
└── labels/
|
||||
├── train/ # 训练集标注(.txt)
|
||||
└── val/ # 验证集标注(.txt)
|
||||
|
||||
数据划分:
|
||||
- 使用固定随机种子保证可重复性
|
||||
- 默认20%作为验证集
|
||||
- 保持图片和标注的对应关系
|
||||
|
||||
使用示例:
|
||||
# 基础使用(默认参数)
|
||||
python scripts/prepare_yolo_dataset.py
|
||||
|
||||
# 自定义参数
|
||||
python scripts/prepare_yolo_dataset.py \
|
||||
--root digit-validation \
|
||||
--out yolo_dataset \
|
||||
--val-ratio 0.2 \
|
||||
--seed 42
|
||||
|
||||
# 只使用训练集(不划分验证集)
|
||||
python scripts/prepare_yolo_dataset.py --val-ratio 0.0
|
||||
|
||||
注意事项:
|
||||
- 确保coco.json中的file_name与实际图片文件匹配
|
||||
- 类别ID必须是0-9(数字)
|
||||
- 边界框坐标不能超出图片范围
|
||||
- 输出目录会被覆盖,注意备份

图片预处理工具 - 提升数字识别效果
|
||||
|
||||
功能说明:
|
||||
对数字图片进行多种预处理,以提升YOLO模型的识别效果。
|
||||
支持多种预处理方法,可单独使用或组合使用。
|
||||
|
||||
主要特性:
|
||||
- 多种预处理方法(6种)
|
||||
- 支持批量处理
|
||||
- 可保持彩色或转为灰度
|
||||
- 实时进度显示
|
||||
- 可预览处理效果
|
||||
- 自动创建输出目录
|
||||
|
||||
预处理方法详解:
|
||||
1. auto (自动增强):
|
||||
- 去噪 + 锐化
|
||||
- 适合一般场景
|
||||
|
||||
2. clahe (对比度限制自适应直方图均衡化):
|
||||
- 增强局部对比度
|
||||
- 突出数字边缘
|
||||
- 推荐用于低对比度图片 ⭐
|
||||
|
||||
3. binary (自适应二值化):
|
||||
- 将图片转为黑白
|
||||
- 适合文档类图片
|
||||
- 可能丢失信息,谨慎使用
|
||||
|
||||
4. denoise (去噪):
|
||||
- 去除图片噪点
|
||||
- 保持边缘清晰
|
||||
- 适合噪声较大的图片
|
||||
|
||||
5. sharpen (锐化):
|
||||
- 增强边缘和细节
|
||||
- 使数字更清晰
|
||||
- 可能放大噪声
|
||||
|
||||
6. combined (组合方法):
|
||||
- CLAHE + 去噪 + 锐化
|
||||
- 综合效果最好
|
||||
- 处理时间较长
|
||||
|
||||
重要提示:
|
||||
- 训练和预测必须使用相同的预处理方法!
|
||||
- 建议使用 --keep-color 保持彩色,避免训练/预测不一致
|
||||
- clahe + keep-color 是推荐的最佳组合 ⭐
|
||||
|
||||
使用场景:
|
||||
场景1: 预处理训练数据
|
||||
python scripts/preprocess_images.py \
|
||||
--input digit-validation/images \
|
||||
--output digit-validation-processed \
|
||||
--method clahe \
|
||||
--keep-color
|
||||
|
||||
场景2: 预处理验证数据
|
||||
python scripts/preprocess_images.py \
|
||||
--input valid \
|
||||
--output valid-processed \
|
||||
--method clahe \
|
||||
--keep-color
|
||||
|
||||
场景3: 预览效果(处理前3张)
|
||||
python scripts/preprocess_images.py \
|
||||
--input valid \
|
||||
--output test-output \
|
||||
--method clahe \
|
||||
--show-preview
|
||||
|
||||
场景4: 测试不同方法
|
||||
for method in auto clahe binary denoise sharpen combined; do
|
||||
python scripts/preprocess_images.py \
|
||||
--input valid \
|
||||
--output valid-${method} \
|
||||
--method ${method} \
|
||||
--keep-color
|
||||
done
|
||||
|
||||
输出:
|
||||
- 处理后的图片(与输入文件名相同)
|
||||
- 图片质量分析报告
|
||||
- 处理统计信息
|
||||
|
||||
性能:
|
||||
- 处理速度: ~0.1s/张(CPU)
|
||||
- 支持格式: JPG, JPEG, PNG, BMP
|
||||
- 保持原图尺寸不变
|
||||
|
||||
依赖环境:
|
||||
- opencv-python >= 4.0.0
|
||||
- numpy
|
||||
- tqdm(进度条)

YOLO数字识别模型训练脚本
|
||||
|
||||
功能说明:
|
||||
使用YOLOv8在准备好的数字数据集上训练目标检测模型。
|
||||
支持从预训练模型开始进行迁移学习,加速训练过程。
|
||||
|
||||
主要功能:
|
||||
- 加载YOLO预训练模型(yolov8n.pt等)
|
||||
- 在数字数据集上进行训练
|
||||
- 自动保存最佳模型和最后模型
|
||||
- 训练完成后自动验证
|
||||
- 可选:在valid文件夹上进行推理测试
|
||||
|
||||
训练流程:
|
||||
1. 加载预训练模型(ImageNet或COCO预训练)
|
||||
2. 在数字数据集上微调
|
||||
3. 每个epoch保存检查点
|
||||
4. 根据验证集mAP保存最佳模型
|
||||
5. 训练完成后加载最佳模型进行验证
|
||||
|
||||
输出文件:
|
||||
runs/digit_yolo/<name>/
|
||||
├── weights/
|
||||
│ ├── best.pt # 最佳模型(验证集mAP最高)
|
||||
│ └── last.pt # 最后一个epoch的模型
|
||||
├── results.csv # 训练指标(loss, mAP等)
|
||||
├── results.png # 训练曲线图
|
||||
├── confusion_matrix.png # 混淆矩阵
|
||||
└── args.yaml # 训练参数记录
|
||||
|
||||
训练参数说明:
|
||||
- epochs: 训练轮数(100-200推荐)
|
||||
- batch: 批次大小(根据显存调整,CPU建议8-16)
|
||||
- imgsz: 输入图片大小(320快速,640精确)
|
||||
- model: 预训练模型(yolov8n最轻量,yolov8s/m更准确)
|
||||
|
||||
性能优化建议:
|
||||
CPU训练:
|
||||
- batch=8-16
|
||||
- imgsz=320
|
||||
- workers=4
|
||||
- 训练时间: ~2-3小时/100轮
|
||||
|
||||
GPU训练:
|
||||
- batch=32-64
|
||||
- imgsz=640
|
||||
- 训练时间: ~10-20分钟/100轮
|
||||
|
||||
使用示例:
|
||||
# 基础训练(100轮)
|
||||
python scripts/train_yolo.py
|
||||
|
||||
# 长时间训练(200轮)
|
||||
python scripts/train_yolo.py --epochs 200 --name exp_200
|
||||
|
||||
# 使用更大模型
|
||||
python scripts/train_yolo.py --model yolov8s.pt --epochs 150
|
||||
|
||||
# 高清训练
|
||||
python scripts/train_yolo.py --imgsz 640 --batch 8 --name exp_hd
|
||||
|
||||
# 自定义输出目录
|
||||
python scripts/train_yolo.py \
|
||||
--project my_runs \
|
||||
--name my_experiment \
|
||||
--epochs 150
|
||||
|
||||
监控训练:
|
||||
# 实时查看训练指标
|
||||
tail -f runs/digit_yolo/<name>/results.csv
|
||||
|
||||
# TensorBoard可视化(可选)

主函数:执行YOLO模型训练流程
|
||||
|
||||
完整流程:
|
||||
1. 解析命令行参数
|
||||
2. 加载YOLO预训练模型
|
||||
3. 开始训练(自动保存检查点)
|
||||
4. 训练完成后加载最佳模型
|
||||
5. 在验证集上评估性能
|
||||
6. 可选:在valid文件夹上进行推理
|
||||
|
||||
训练输出:
|
||||
- 每个epoch的训练和验证指标
|
||||
- 混淆矩阵
|
||||
- PR曲线
|
||||
- 训练曲线图
|
||||
- 最佳和最后模型权重
|
||||
|
||||
验证指标:
|
||||
- mAP50: IoU=0.5时的mAP(主要指标)
|
||||
- mAP50-95: IoU从0.5到0.95的平均mAP
|
||||
- Precision: 精确率
|
||||
- Recall: 召回率
|
||||
- 每个类别(数字0-9)的性能
|
||||
|
||||
异常处理:
|
||||
- FileNotFoundError: 数据集配置文件不存在
|
||||
- RuntimeError: 训练失败或模型加载失败
