To better understand the challenges of large datasets with clear cardinality, let's assume that your log file contains 16-character IDs, and you want to count the number of different IDs. For example: 4f67bfc603106cb2 These 16 characters need to be represented in 128 bits. 65,000 IDs will require 1MB of space. We receive 30多亿条 event records every day, each with an ID. These IDs require 384 billion-bit or 45GB of storage. And that's just the space the ID field needs. We take an easy way to get

how to get the parameters R (rotation matrix) and T (translation vector) of the coordinate transformation, so that the three-dimensional data measured at two angles of view is the smallest distance after the coordinate transformation, and the current registration algorithm can be divided into the whole registration and the local registration according to the process. There is a separate registration module in the PCL, which realizes the basic data structure of registration and the classical reg
