摘要
文章提出了一种基于OpenCV的圆形标记点的提取方法,通过对图像进行平滑处理、边缘检测、轮廓查找、几何约束以及椭圆拟合,实现圆形标记点的提取,求出中心坐标。该方法主要应用于多视点云拼接以及其他有关圆形物体识别的场合。实验结果证明,该方法能快速有效的提取圆形标记点。
This study proposes a circular markers extraction method based on OpenCV. After image smoothing, edge detection, contour finding geometric constraints and ellipse fitting, the circular markers are extracted, and the center coordinates are computed. This method is mainly used in multi-view point clouds registration and other round object recognition occasions. Experiments results prove that this meth- od is fast and efficient to extract circular markers.
