PCL点云配准(1) is a project mainly written in , based on the .在逆向工程,计算机视觉,文物数字化等领域中,由于点云的不完整,旋转错位,平移错位等,使得要得到的完整的点云就需要对局部点云进行配准,为了得到被测物体的完整数据模型,需要确定一个合适的坐标系,将从各个视角得到的点集合并到统一的坐标系下形成一个完整的点云,然后就可以方便进行可视化的操作,这就是点云数据的配准。点云的配准有手动配准依赖仪器的...

PCL点云分割(2) is a project mainly written in , based on the .关于点云的分割算是我想做的机械臂抓取中十分重要的俄一部分,所以首先学习如果使用点云库处理我用kinect获取的点云的数据,本例程也是我自己慢慢修改程序并结合官方API 的解说实现的,其中有很多细节如果直接更改源程序,可能会因为数据类型,或者头文件等各种原因编译不过,会导致我们比较难得找出其中的错误,首先我们看一下我自己设定的一个场景,...
PCL行人检测 is a project mainly written in , based on the .首先我们知道Hog特征结合SVM分类器已经被广泛应用于图像识别中,尤其在行人检测中获得了极大的成功,HOG+SVM进行行人检测的方法是法国研究人员Dalal在2005的CVPR上提出的,而如今虽然有很多行人检测算法不断提出,但基本都是以HOG+SVM的思路为主,那么PCL中也是利用这一思想来进行行人的检测, 总体思路: 1、提取...
