There is a baseline you can run as-is — starting from it is usually far faster than building from scratch.
Document-image dataset: 2,797 training and 597 test samples
If the items below still feel unfamiliar, you usually get a better result by preparing first instead of rushing in.
PaddlePaddle 2.0+
文档边缘检测
图像分割与热力图
四角点坐标回归
OpenCV 图像处理
Python 推理脚本与 ZIP 打包
The real friction is usually not library usage. It is validation, time allocation, and task framing.
难点不只是识别文档边缘，还要在真实拍摄背景下稳定定位文档四个角，并兼顾泛化效果与推理速度。若想取得更高分，页面明确建议直接回归四个角点；同时必须按指定的 predict.py、结果目录和 ZIP 结构提交可运行的模型。
