The present invention relates to the technical field of point cloud data compression, and in particular to a method, device, computer equipment, and medium for compressing dynamic point cloud data. The method divides a target space into subspaces, counts the number of data containing point cloud data in the subspaces, sorts them using the number of data as a spatial identifier, obtains a primary identifier sequence, determines a subspace that meets preset conditions as a target subspace, determines the sorting position of the target subspace, obtains a secondary identifier sequence of the target subspace using the above steps, forms target description information based on the sorting positions and secondary identifier sequences of all target subspaces, obtains a target probability distribution based on the target description information and reference description information, encodes the target probability distribution as a compression result, obtains a refined spatial domain description through spatial averaging, and extracts the time domain correlation of dynamic point cloud data, thereby improving the compression efficiency and compression rate of dynamic point cloud data, thereby reducing the storage pressure of point cloud modeling in medical scenarios.

This invention relates to a method, apparatus, electronic device, and storage medium for automated accounting testing. The automated accounting testing method includes the following steps: acquiring order information and corresponding merchant configuration information and marketing information; calculating and generating order data to form a basic dataset based on the acquired information and acquiring business logic; comparing the order information in the basic dataset with the corresponding order data in the acquiring system to generate a primary identifier field; calculating the settlement amount using the correct order data from the comparison and merchant revenue sharing information according to the clearing rules, comparing it with the settlement amount of the acquiring system's batch clearing tasks to generate a secondary identifier field for the corresponding order data; generating corresponding accounting entries based on the order data using an account table and rule table, verifying them against the entries generated by the acquiring system to generate a tertiary identifier field for the corresponding order data; and generating a test report based on the identifiers at each level and the basic data information.
