Embodiment Construction

[0045] The specific implementation manner of the present invention will be described in more detail below with reference to schematic diagrams. The advantages and features of the present invention will be more apparent from the following description. It should be noted that all the drawings are in a very simplified form and use imprecise scales, and are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention.

[0046] figure 1 It is a flow chart of the high-frequency data storage method provided by the embodiment of the present invention. like figure 1 As shown, the high-frequency data storage method includes:

[0047] Step S1: Register the data types to be stored, and create corresponding memory pools, notification queues, threads, and data block read / write handles for each registered data type;

[0048] Step S2: Monitor the notification queue in real time, and when applying for a data block from the corresponding me...

Abstract

The present invention provides a high-frequency data storage method, device, and computer. After calling the write method, any class with a data block read / write handle will apply for a memory data block from the memory pool and put it into the notification queue. When there are data blocks in the queue, the file stream creation module will be awakened to create independent files and write threads. After the file is written to the thread, the data block will be released and returned to the memory pool. Because each registered data type is allocated an independent memory pool and thread resources, the memory pool and multi-threading technology can be fully utilized to effectively improve data storage efficiency.

Description

technical field [0001] The invention relates to the technical field of laser radar, in particular to a high-frequency data storage method, device and computer. Background technique [0002] LiDAR scanning system is a high-tech tool. LiDAR technology can quickly acquire high-density and high-precision laser point cloud data. Through post-processing point cloud data, a three-dimensional model with centimeter-level accuracy can be established. This technology has been widely used in resource exploration, urban planning, agricultural development, land use, environmental monitoring, earthquake prevention and disaster reduction and other fields. Lidar technology can quickly acquire high-density and high-precision laser point cloud data, and through post-processing point cloud data, it can establish a three-dimensional model with centimeter-level accuracy. However, due to the huge amount of data collected by this technology (usually terabytes), it is also accompanied by various da...
