What does the point cloud txt format mean?

Point cloud is usually used in three-dimensional vision, lidar, robot autonomous navigation and other fields, and it is a three-dimensional data set composed of a large number of discrete points. The point cloud txt format refers to saving the point cloud data as a plain text file, and each line represents the position and color information of a point. This format is easy to understand, handle and transmit, and it is also readable and easy to read and edit manually.

The feature of point cloud txt format is that point cloud data can be easily imported into various softwares and platforms for processing, editing and visualization, such as MATLAB and CloudCompare. Moreover, because of its simple format, point cloud data can be added, deleted and checked directly through a text editor. In addition, the point cloud txt format is also very suitable for point cloud data transmission on the network, saving the time and cost of data transmission.

Point cloud txt format has been widely used in various fields. For example, in the field of laser scanning, the point cloud data captured by the laser scanner can be saved in the format of point cloud txt, and then three-dimensional reconstruction can be carried out through subsequent algorithms; In the field of robots, point cloud txt format can be used to save the environmental information detected by lidar and guide robots to navigate autonomously. In the field of 3D vision, 3D models can be saved in point cloud txt format for subsequent editing and application. Generally speaking, the point cloud txt format is a very convenient and universal point cloud data format, and it is gradually becoming an important standard for point cloud data processing and visualization.
