Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

准备 CR2 原始数据

  • 在导入前应用相同白平衡以统一灰度映射,避免每张图不同阈值输出差异
  • 对高 ISO 的 CR2 先进行降噪,否则噪点会在二值 PBM 中被放大为黑点
  • 使用相机或 RAW 解码器的线性光或曝光补偿以确保阴影细节在阈值阶段可控
  • 检查 CR2 的黑电平与光学裁切参数并在解码时修正以避免边缘假黑
  • 对来自不同机型的 CR2 批量预先应用相同色彩矩阵以减少解码差异

设置 PBM 导出参数

  • 选择明确的阈值或自适应局部阈值来控制二值化结果的连通性
  • 在需要平滑边缘的场景使用轻度模糊或抗锯齿滤波器再二值化
  • 设定目标分辨率以匹配后续 CNC/印刷要求,避免现场再缩放
  • 若目标需要掩模,考虑导出为高分辨率 PBM 以减少细节丢失
  • 将每组输出打包为 ZIP 以便在设备间传输并记录对应的阈值配置

验证与质量控制

  • 在 100% 缩放下检查边缘连通性以确认切割路径或掩模无断点
  • 对比 CR2 灰度直方图与 PBM 黑白占比,确保阈值未过度偏移
  • 随机抽样几张 PBM 在目标设备(激光/相机)上进行实测以验证耐用性
  • 保存 CR2 原始以便出现问题时回退并调整预处理参数
  • 记录每次批处理的参数集以便重现或审计输出差异

工作流与隐私考量

  • 在本地设备完成 CR2 解码以避免上传敏感拍摄内容
  • 对于大批量转换,分组 20–50 张以平衡内存占用和吞吐量
  • 在低内存设备上减少并行转换任务并关闭其他内存密集型应用
  • 立即下载并备份生成的 PBM,以防浏览器会话清除临时数据
  • 将原始 CR2 与其对应 PBM 配对命名以便于后续追踪
