Embodiment Construction

[0052] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0053] 1. Integrated measurement data storage format

[0054] The integrated measurement data storage format includes two parts, the common file header and the point data record package (such as figure 1 shown). The common file header describes the overall information of the system integrated measurement data storage file, and the point data record package records specific information such as the measured point, and its record content is optional in the integrated measurement data storage file.

[0055] (1) Public file header

[0056] Common file headers (such as figure 2 shown) is used to record the basic information of the integrated shipborne water shoreline integrated measurement system, such as version number, sensor model, file creation date and other information, as well as the multi-sensor corresponding to the project selected by the...

Abstract

The invention discloses a real-time storage method for ship-borne multi-sensor integrated measurement data, which belongs to the technical field of marine surveying and mapping. Thread network communication, time synchronization control and memory pool technology realize the real-time storage of ship-borne multi-sensor integrated measurement data, and store the collected multi-source data into the same file. The ship-borne multi-sensor integrated measurement data real-time storage method of the present invention effectively improves the integration degree of the ship-borne water shoreline integrated measurement system, overcomes the defect of multi-sensor storage efficiency redundancy, and improves the measurement data storage performance.

Description

technical field [0001] The invention relates to the technical field of marine surveying and mapping, in particular to a method for real-time storage of ship-borne multi-sensor integrated measurement data. Background technique [0002] The ship-borne water shoreline integrated measurement system integrates 3D laser scanner, multi-beam depth sounder, GNSS (Global Navigation Satellite System), IMU (inertial measurement unit), sensor stabilization platform and other sensors, and adopts non-contact measurement Synchronously obtain the topography of the water and underwater, which has great application value in the surveying and mapping of coastal zones and islands and reefs. However, for its measurement data management, there is currently no effective real-time storage method for ship-borne multi-sensor integrated measurement data. At this stage, the method of separately storing above-water and underwater data is used. The data integration degree is not high enough, and there are...
