- 🖼️ 滑动验证码(缺口检测) / Slide CAPTCHA (gap detection)
### API解决 / API Solving (付费/APIs)
- reCAPTCHA v2/v3
- hCaptcha
- Cloudflare Turnstile
- 2Captcha / Anti-Captcha
## 使用方法 / Usage
```bash
# 识别图片验证码
python solve.py --image captcha.png
# 解决reCaptcha
python solve.py --recaptcha "site_key" --url "page_url"
# 滑动验证码
python solve.py --slide background.png --template slider.png
```
## 配置 / Configuration
### 本地OCR
```python
# 默认使用Tesseract
TESSERACT_CMD = "/usr/bin/tesseract"
LANG = "eng+chi_sim" # 支持中英文
```

```python
# 2Captcha
API_2CAPTCHA = "your_api_key"
# Anti-Captcha
API_ANTI_CAPTCHA = "your_api_key"
```

- 灰度转换 / Grayscale
- 二值化 / Binarization
- 去噪 / Denoising
- 锐化 / Sharpening
### 2. 字符分割
- 连通域分析 / Connected component analysis
- 投影法 / Projection method
### 3. 字符识别

- 轨迹生成 / Trajectory generation
## 示例 / Examples
### 简单文本识别
```python
from solver import CaptchaSolver
solver = CaptchaSolver()
result = solver.solve_image("captcha.png")
print(result) # 输出识别的字符
```
### 滑动验证码
```python
result = solver.solve_slide(bg_img, slider_img)
print(result) # 输出滑动距离
```
### reCaptcha
```python
result = solver.solve_recaptcha(site_key, page_url)
print(result) # 输出token
```
