Semantic segmentation is the basis of computer vision's understanding of the real world, ranging from automatic driving to personal applications. As long as you observe carefully, you can find the application places of semantic segmentation everywhere. In fact, semantic segmentation is equivalent to image segmentation + understandi ...

1. Parameter description
Since almost all classes in PCL inherit from the basic pcl::PCLBase class, the pcl::Feature class accepts input data in two different ways:
A complete point cloud data set is forced through setinputcloud (pointcloudconstptr &) Any ...

1. Time stamp of TF coordinate broadcast
1.1. Function of timestamp
First clarify what is the coordinate transformation of TF: in fact, it is the pose represented by the child coordinate system in the parent coordinate system, which can also be regarded as the coordinate transformation relationship from the child coo ...

1, Algorithm principle
1. Principle overview
the point cloud data set generated by lidar sometimes receives echo signals incorrectly, which will lead to some wrong values. Due to the influence of measurement errors caused by scanning results, errors will inevitably occur in other processing of the point cloud, and some noise ...
