A method for precise delamination of contaminated soil based on three-dimensional gridding
By using the intersection calculation of three-dimensional voxel mesh and global equipment envelope surface and generating guide trajectories through dynamic cutoff points, the problems of equipment overload and trajectory deviation in the layered stripping of contaminated soil were solved, achieving precise separation of contaminated soil and efficient operation of equipment.

Abstract
本申请涉及污染土壤修复技术领域，公开了一种基于三维网格化的污染土壤精准分层剥离方法，包括构建含污染浓度属性的三维体素网格，提取目标浓度曲面，建立挖掘设备运动学方程生成局部机具包络曲面并映射至全局坐标系；对目标浓度曲面与全局机具包络曲面执行三维布尔交集运算，生成初始随形挖掘轨迹，沿该轨迹进行体素体积积分计算，当累积切削土体积达到设备容积阈值时确立动态截断点，生成收斗闭合轨迹并合成引导轨迹；最后根据实际扫掠体移除体素更新地质模型，将截断点作为下一周期起始约束点。本发明解决了固定深度切削不贴合污染曲面、机具超载溢出散落以及缺乏动态更新导致连续作业轨迹偏离实际地表的问题。
