Laser-scan Assisted Repoussé Layout
激光扫描辅助浮雕放样
标签：激光扫描, 放样, 等高线, 浮雕小稿, 数字化
先用油泥或 3D 软件做浮雕小稿，激光扫描（精度 0.05–0.1 mm）生成点云并输出等高线图；按 0.5–1 mm 高差打印分层纸样贴于铜板背面，指导顶出顺序与深度。相比自由手捏，此法大幅减少比例失调，退火次数由 6–8 轮降至 2–3 轮，适合人像、动物等复杂题材的浮雕底稿转移。
Make a maquette in clay or 3D software, laser-scan it (0.05–0.1 mm accuracy) into a point cloud, and output contour maps; print layered paper patterns at 0.5–1 mm height steps and glue them to the sheet back to guide punch order and depth. Versus freehand, proportions hold true and annealing rounds drop from 6–8 to 2–3—well suited to figures and animal subjects. ---
