Deploying BiSeNetV2 model with OpenVINO in Ubuntu 20.04 environment
1. Overview
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 ...

3D reconstruction tool -- pclpy tutorial point cloud features
This tutorial is open source: GitHub Welcome, star
1, Normal estimation
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 ...

Timestamp of TF transform in ROS learning
reference resources
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 ...

pclpy statistical filtering
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 ...

Write C + + server by hand (37): tear code by hand -- asynchronous connect, the cornerstone of high concurrency multithreading technology [10000 words long text]
Navigation for this series of articles: Write C + + server by hand (0): column - Summary navigation [updating]
The default blocking mode is used when connect is created, but in reality, the connection speed may be slow due to poor network, intermediate proxy server, gateway and other factors. At this time, in blocking mode, the pr ...
