Abstract

The invention relates to a method for realizing an overwater and underwater integrated distributed high-speed video measurement system, which comprises the following steps of: 1) a distributed high-speed video sensor networking method: adopting multi-node data storage and transmission to obtain a high-speed video image sequence of a target structure; and 2) a distributed high-speed sequence image target identification and three-dimensional reconstruction method: adopting distributed parallel calculation for analyzing dynamic deformation parameters of the target structure in the obtained high-speed video image sequence. Compared with the prior art, the method has the advantages of high precision, high real-time performance, strong robustness and high reliability.

Description

technical field [0001] The invention relates to the field of high-speed video measurement, in particular to an implementation method of an integrated distributed high-speed video measurement system above and below water. Background technique [0002] With the continuous expansion and extension of application fields, high-speed video measurement methods have been continuously improved. The massive image data collected by high-speed cameras brings a huge computational burden. In the current research status at home and abroad, the main data processing method of high-speed video measurement is centralized post-processing (Liu et al., 2015; Ye et al., 2018). This traditional data processing method shows problems such as low data processing efficiency and low degree of automation, and cannot meet the requirements of on-site computing. The distributed parallel computing method has greatly improved the data processing efficiency, but the current research on distributed high-speed v...
