SHOT-QC-AUTOMATION
|
|||
|
|
镜头QC自动化 — 每个镜头自动拆帧，检查竖屏、字幕、换脸、牌匾、遮挡、现代物品。
|
|||
|
|
|
|||
|
|
功能:
|
|||
|
|
1. 输入视频文件
|
|||
|
|
2. 自动拆帧
|
|||
|
|
3. 检查:
|
|||
|
|
- 竖屏 (9:16)
|
|||
|
|
- 字幕存在性和位置
|
|||
|
|
- 换脸 (与参考图对比)
|
|||
|
|
- 牌匾文字正确性
|
|||
|
|
- 遮挡 (人物被遮挡)
|
|||
|
|
- 现代物品 (手机、汽车等)
|
|||
|
|
4. 输出 QC 报告 JSON
|
|||
|
|
|
|||
|
|
依赖:
|
|||
|
|
pip install opencv-python numpy # 基础
|
|||
|
|
pip install pytesseract # OCR (需要系统安装 tesseract)
|
|||
|
|
# YOLO 可选: pip install ultralytics
|
|||
|
|
|
|||
|
|
用法:
|
|||
|
|
python shot-qc-automation.py --video input.mp4 --character CHAR-003-SuBai
|
|||
|
|
python shot-qc-automation.py --batch video_list.json
|

python shot-qc-automation.py --video input.mp4 --output qc_report.json
