摘要
复杂曲面的建模是计算机视觉和计算机图形学领域的重要研究内容,在工业制造、目标检测和过程质量控制中具有重要的应用价值。提出一种基于标志点约束的自动匹配建模方法,该方法利用粘贴在目标物体表面的标志点进行匹配,把局部采集的深度像数据匹配到同一坐标系下,实现复杂曲面的自动建模。该方法能有效地实现自由曲面的深度像匹配,并且过程中不需要人工操作就能实现复杂曲面的自动建模,操作简便,在实际工程中具有重要的应用价值。实验结果验证了算法的鲁棒性和有效性。
The modeling of complex surfaces is an important research content in the field of computer vision and computer graphics. It has important application value in industrial manufacturing, target detection and process quality control. An automatic matching modeling method based on marker point constraint is proposed. This method uses the marker points pasted on the surface of the target object to match, and the locally acquired depth image data is matched to the same coordinate system to realize the automatic modeling of complex surfaces. The method can effectively realize the depth image matching of the free-form surface, and the automatic modeling of the complex surface can be realized without manual operation in the process, and the operation is simple, and has important application value in practical engineering. The experimental results verify the robustness and effectiveness of the algorithm.
