摘　　要：为提高TiC颗粒增强钨基复合材料烧蚀形貌重构精度和抗烧蚀性能,提出基于数字图像处理的TiC颗粒增强钨基复合材料烧蚀形貌重构方法。用氧乙炔烧蚀装置进行烧蚀试验,利用三目立体视觉系统采集烧蚀图像,通过阈值分割法,将图像转换为二维图像数据。用微分算子法提取二维图像轮廓,用NURBS曲线延拓、拟合二维图像轮廓曲线,通过匹配点的空间坐标曲线拟合图像轮廓特征数据,实现TiC颗粒增强钨基复合材料烧蚀形貌重构。结果表明:该方法对TiC颗粒增强钨基复合材料烧蚀形貌数据重构精度较高,重构目标点与原始数据点误差较小,对提高TiC颗粒增强钨基复合材料抗烧蚀性能有一定指导。In order to improve the accuracy and anti ablation performance of Ti C particle reinforced tungsten matrix composites,adigital image processing based ablation morphology reconstruction method of Ti C particle reinforced tungsten matrix compositeswas proposed. The ablation experiment was carried out with oxyacetylene ablation device. The image of ablation morphology wascollected by three eyes stereo vision system. The image was converted into two-dimensional image data by threshold segmentationmethod. The two-dimensional image contour was extracted by differential operator method. The NURBS curve was used to extendand fit the two-dimensional image contour curve. The feature data of the image contour was fitted by the spatial coordinate curveof the matching points. The ablation morphology reconstruction of Ti C particle reinforced tungsten matrix composites wasrealized. The results show that the ablation morphology data reconstruction accuracy of Ti C particle reinforced tungsten matrixcomposites is high,and the error between reconstruction target point and original data point is small,which has certain guidancefor improving the ablation resistance of Ti C particle reinforced tungsten matrix composites.
