According to the vehicle foothold generation method, the accuracy of foothold generation is improved.

The embodiment of the invention provides a data processing method, a distributed database system, electronic equipment and a computer storage medium. The data processing method is applied to fragment nodes in the distributed database system. The method comprises the following steps: receiving a physical DDL instruction converted from a logic DDL instruction for changing data in the distributed database system; executing the physical DDL instruction, and after the physical DDL instruction is successfully executed, generating a fragment node mode snapshot for the fragment node; and if it is determined that the fragment node mode snapshot is inconsistent with the global logic mode snapshot of the distributed database system, adjusting log data of the fragment node converged into a global log to be consistent with the global logic mode snapshot. Through the embodiment of the invention, the problem of data processing exception caused by multiple data versions in the DDL change process of the distributed database system is effectively solved.

The invention relates to a continuous data protection method based on a jump recovery chain, which belongs to the technical field of computer storage and aims at reducing the data recovery time of continuous data protection and improving the performance of writing operation and data recovery. The algorithm includes a write operation algorithm and a data recovery algorithm, and adopts the jump recovery chain technology to ensure that the system can recover to any point in time before the failure in a short period of time without inserting a snapshot, that is, the data recovery time and recovery point time The span is irrelevant, effectively solving the problem of fast recovery of long-term data; at the same time, data buffering technology is used in the write operation algorithm and data recovery algorithm to improve the write operation performance and data recovery performance of the jump recovery chain.

A malicious URL detection method, apparatus, and storage medium are provided. The method includes rolling back a virtual machine to an initiating state in response to detecting a trigger event of the virtual machine. In the initiating state, page content of a target URL is loaded using the virtual machine. Using the virtual machine, an application program linked to the page content is run. A system snapshot file of the virtual machine is obtained in at least one state of the initiating state, a state in which the loading of the page content is completed, or a state in which the application program is being run. Malicious URL detection is performed on the target URL based on the obtained system snapshot file.

The invention discloses a motor vehicle snapshot method, a motor vehicle snapshot device and a computer storage medium, and the method comprises the steps: obtaining a real-time monitoring image, obtaining motor vehicle information and non-motor vehicle information in the real-time monitoring image, extracting motor vehicle key points of a motor vehicle based on the motor vehicle information, and storing the motor vehicle key points in the computer storage medium; non-motor vehicle key points of the non-motor vehicles are extracted based on the non- And when the position relationship between the motor vehicle key point and the preset motor vehicle snapshot line meets a first snapshot condition and the position relationship between the non-motor vehicle key point and the preset non-motor vehicle snapshot line meets a second snapshot condition, capturing a motor vehicle image in the real-time monitoring picture. According to the motor vehicle snapshot method, the snapshot line is preset on the real-time monitoring picture, the target motor vehicle in the real-time monitoring picture is subjected to real-time snapshot according to the relative distance relation between the key point positions of the motor vehicle and the non-motor vehicle and the snapshot line, and the snapshot effect of high capture rate and accuracy can be achieved.

The present invention provides a method, device, system, and computer storage medium for identifying persons in the same company. The identifying method for accompanying persons includes: acquiring snapshot data of the target person and generating a first data set; determining an effective snapshot time according to the first data set Segment and predetermined coverage area, obtain the snapshot data of the predetermined coverage area within the effective capture time period, and save it as the second data set; extract the face image in it based on the second data set, and save it as the snapshot data Face collection; cluster the face images in the snapshot data face collection to obtain accurate peer recognition results. According to the method, device, system and computer storage medium of the present invention, accurate and comprehensive snapshot data are obtained through area search and secondary recognition of snapshot images, and peer-to-peer analysis of human faces is performed to ensure the accuracy of the results.

The invention discloses a snapshot recognition method, device and system and a computer storage medium. The method comprises the steps that initial resolution configuration information is sent to an image sensor through a first communication data line, so that the image sensor is initialized; a plurality of different pieces of pre-cached real-time resolution configuration information are sent to the image sensor according to the time sequence through the first communication data line; control information is sent to the FPGA through a second communication data line, so that the FPGA starts to output a time sequence control signal to the image sensor; the initial resolution configuration information and each piece of real-time resolution configuration information respectively correspond to a unique time sequence control signal; all snapshot picture data generated by the image sensor according to all the time sequence control signals are obtained through the differential data line and recognized.
