Curved surface laser cladding rapid track planning method based on point cloud model

The invention discloses a curved surface laser cladding rapid track planning method based on a point cloud model. The curved surface laser cladding rapid track planning method is implemented by the following steps that (1), the surface of a part with manufacturing defects of a certain depth, or mistaken machining damage or service damage is scanned and subjected to noise point removing and simplifying treatment by using software to obtain point cloud data omega; (2), parallel planes are set and called cutting pieces, a point cloud is cut through the parallel planes, and it is stipulated that the motion direction of a laser head is the direction of the cutting pieces; (3), intersections of the cutting pieces and the point cloud are calculated; (4), interpolation points are searched; and (5), the posture of a laser beam is calculated. 本发明公开种基于点云模型的曲面激光熔覆快速轨迹规划方法，它包括以下步骤予以实现：1)使用软件对具有定深度制造缺陷、误加工损伤或服役损伤的零件表面扫描并去噪声点及简化处理后得到个点云数据Ω，2)设定平行平面称为切片，以平行平面切割点云；规定激光头的运动方向为切片的方向；3)计算切片与点云的交点；4)插补点搜索；5)计算激光束的姿态。
