For the RANSAC step, I'm using the functionopen3d.pipelines.registration.registration_fgr_based_on_feature_matchingthat is in the latest version of the Open3D package (0.14.1). Running these steps over one pair of images isn't a problem. But, when I'm running it in a loop 100 times,...
How can I access the Feature? I created the fpfh pcd_fpfh = o3d.pipelines.registration.compute_fpfh_feature(pcd_down,o3d.geometry.KDTreeSearchParamHybrid(radius=50, max_nn=100)) pcd_fpfh It would be great to be able to display these feat...

大型点云场景,直接ICP会耗费很大的内存和时间,这里人工提取关键点,将关键点位移配准到关键点,即可得到旋转矩阵,然后作为大点云的旋转矩阵。 Open3d 关键点ICP,人工提点后的一个简单的ICP 前言 ICP算法有很多;Open3d自带的全局快速注册execute_fast_global_registration可以计算FPFH特征,快速对齐点云,这里不做介绍,当你...
点云的粗配准(coarse registration)是指通过快速但不精确的方法,对两个点云进行初步对齐,使它们的大致位置和方向一致;精配准(fine registration)则是在粗配准的基础上,使用精确但计算量较大的算法,如ICP(Iterative Closest Point),对点云进行细致调整,以达到高精度的对齐。 点云配准的本质是通过几何变换(包括旋转、...
