A method of point cloud data processing includes determining a 3D region of a point cloud data and a 2D region of a point cloud track patch frame onto which one or more points of the point cloud data are projected; and reconstructing, based on patch frame data of the a point cloud ...

A point cloud is a collection of data points in 3D space, where each point represents the X-, Y-, and Z-coordinates of a location on a real-world object’s surface, and the points collectively map the entire surface. Point clouds are commonly produced bylidar scanners, stereo cameras, a...

Below we introduce some commonly used point cloud data storage formats: Obj: The point cloud file in obj format is developed by Wavefront Technologies. It is a text file. It is a simple data format that only represents the geometry, normal, color, and texture information of the 3D data. ...
Hello, I think I found a bug in the file point_cloud2.py I wrote a python ros node for reading a bag with a pointcloud2 format (and 4 fields, x,y,z,intensity). When I read the 3 first fields, it works fine, but when I read "intensity", i...

What are point clouds? What is point cloud processing? How do you create a point cloud? We answer all your questions in this guide.
The value is in the format of File_name.file_number:Event_position. When MongoDB serves as the source database, the source database logs are obtained from within the time range of the oplog, starting with the current start position. To check whether the start position is within the oplog...
