There are three prime sensor cameras on hand, fixed at different angles, with the intention of stitching up the point cloud data of three cameras according to RGBD information.Device limit + capacity is not enough, the point Cloud Library 1.8 environment has not been built up, so it is unable to read the information in real-time. In addition, the laptop USB chip bus Interrupt protocol limit, also cannot use three cameras simultaneously.In such a pit Dad's situation, share how I do three-dimensio

is the nature of the covariance matrix? is one of the steps in singular value decomposition .... Singular value decomposition is the need to multiply the matrix by its own transpose to obtain a symmetric matrix.Of course, the benefit of covariance calculation is that you can attach different weights to points at different distances.　　Method 2: Based on homogeneous coordinates1. Convert point coordinates to homogeneous coordinates2. Singular value decomposition for the second coordinate3. The ve

PCL is a relatively superior laser point cloud processing library, usually is compiled from the source code, but the compiled dynamic library in the use of the process in the header file will be reported some strange errors, at first naïve thought it is impossible to be the source of the problem, is the problem of their own environment configuration, by Sun Shi brother, suddenly understand the header file errors, The reason for the error is that part

Recently in the construction of point cloud system, the main combination of Point Cloud Library PCL, Visual library VTK and image processing open Source Library OpenCV to combine image and point cloud data collaboration of rock mass analysis system. Here I would like to share with you the overall construction process, the shortage of places I hope you can help to point out in order to improve. Because it is still in the construction process, so the up

B. In this figure there is an interval value of not 0, which has a certain value. The picture below shows a PFH map of the different points in a point cloud. In some cases, D is not a good feature. For 2.5D datasets, such as robots, distance varies with the viewpoint. So, sometimes it's better to omit D. The PFH feature is inside the PCL inside the Pcl_features library. The default PFH is distributed in 5 intervals and does not include distances, s

The filtering, edge detection and segmen

There is a separate registration module in the PCL, which realizes the basic data st

Point Cloud Segmentation is based on the characteristics of space, geometry and texture to divide the point cloud, so that the same division within the point cloud has similar characteristics, point cloud effective segmentation is often the premise of many applications, such as reverse work, the CAD field of parts of the different scanning surface segmentation, and then to better the hole repair surface reconstruction, Feature description and extraction, and then the retrieval based on 3D conten

Introduction Given two sets of three-dimensional data points from different coordinate systems, the transformation relationships of two point set spaces are found, so that the two point sets can be unified into the same coordinate system, that is, the registration process. The goal of the registration is to find the relative position and direction of the separately acquired views in the global coordinate frame, so that the intersecting areas between them are completely overlapping. For each set
