模板匹配
模板匹配是一种图像处理与计算机视觉技术，通过将预先定义的模板图像与目标图像进行像素级相似度比较，定位目标图像中与模板最匹配的区域。其核心原理基于滑动窗口遍历与相似度度量（如均方差、相关系数等），广泛应用于目标检测、工业质检、文档识别及界面自动化等领域，具有实现简单、无需训练数据的特点，但对尺度变化和旋转较为敏感。

Traditional intelligent document processing (IDP) pipelines usually consist of three parts: OCR, template matching, and a rules engine, and their recognition accuracy is decent for known document formats, but they often fail when faced with new formats.
OpenCV's built-in template matching function cv2.matchTemplate slides a template across the target image and computes similarity at each position, with almost no tolerance for scaling and rotation
