The reconstructed point cloud obtained by binocular stereo vision usually has more noise points. The main reason for this phenomenon is that the error of algorithm matching point leads to the error of disparity calculation. SGBM algorithm is good in traditional binocular stereo vision, but it still has ...

Recently, point cloud data processing needs to be used, so PCL point cloud library needs to be installed, which has been struggling for a long time. Due to various reasons such as test delay, etc., it has not been configured successfully for a long time. Only 1.9.1 PCL is configured on VS2017, and conso ...

Using PCL segmentation algorithm  pcl::SACSegmentation<pcl::PointXYZ> seg; , do not use the normal parameters, only get the segmentation patch according to the model parameters, which is far from the imagined patch, 1 pcl::ModelCoefficients::Ptr coefficients (new pcl::ModelCoefficients ()); 2 pcl::PointIndices::Ptr inliers (new ...

Classes and multithreading In the project, a client is needed to communicate with lidar. The main function of the client is to receive the original byte stream sent by the radar and parse it into pcl::PointXYZ type three-dimensional coordinate points which can be directly processed by pcl. The specif ...

Firstly, there are a lot of noise information inevitably in the point cloud in the large scene range. In order to prevent these noise points from interfering in feature extraction of point cloud data, the point cloud data is preprocessed to elimi ...
