Sampling data processing method and product for lidar

A sampling data processing device, comprising a sampling module, at least two intermediate processing modules, a digital center module, a framing module, and a fetching module, wherein:

• the sampling module is configured to sample an echo to obtain sampling data;
• the at least two intermediate processing modules are configured to process the sampling data in sequence to obtain point cloud data, wherein each intermediate processing module is configured to perform data processing on data from an upstream module to obtain intermediate data and then output the intermediate data to a downstream module;
• the digital center module is configured to input the point cloud data into a cache of the digital center module for storage;
• the framing module is configured to read the point cloud data from the cache and generate at least one frame of point cloud data based on the point cloud data;
• the fetching module is configured to, when the module to be analyzed is determined from the at least two intermediate processing modules, fetch data from the module to be analyzed to obtain fetched data;
• the digital center module is further configured to switch to input the fetched data into a cache of the digital center module for storage;
• and
• the framing module is further configured to read the fetched data from the cache and perform fault analysis on the module to be analyzed based on the fetched data.
