摘要
本文提出一种基于图像轮廓进行相机自标定并计算投影矩阵从而恢复物体三维模型的方法。首先使用镜面反射从图像中获取物体的多角度成像并利用阈值和边缘提取得到图像的轮廓信息,再结合对极几何对图像轮廓的限制条件确定相机的投影参数,最后使用可视外壳技术拟合出物体三维模型。
This paper proposes a camera self-calibration and image modeling method based on image silhouette. First mirror reflection is used to show five views of an object, and silhouette is estimated through setting threshold and edge detection. Then the projection matrix is determined based on epipotar geometry constraints. With the camera calibration matrix known, visual hull is used to combine five-view silhouettes to obtain object＇s 3D model.
