Underwater acoustic-optical device precision testing method

Abstract

The invention discloses an underwater acoustic-optical device precision testing method in the technical field of engineering detection and aims to solve the technical problem that in the prior art, the precision of the underwater acoustic-optical device is comprehensively influenced by the device itself and the water environment, resulting in no way to accurately judge the data and detect the credibility of the data. The underwater acoustic-optical device precision testing method comprises the following steps: designing and manufacturing a test platform and a test model; installing the test model and the underwater acoustic-optical device on the test platform; placing the test platform into a test environment; recording measurement data of different measurement distances under the test depth; and obtaining the precision of the underwater acoustic-optical device under the test environment according to the measurement data and the parameters of the test model. According to the underwateracoustic-optical device precision testing method provided by the embedment of the invention, the precision of the underwater acoustic-optical device in the actual detection environment can be determined, accurate judgment on the underwater hidden engineering quality is achieved, and accurate data support is provided for construction quality evaluation or maintenance scheme design.

Description

technical field [0001] The invention belongs to the technical field of engineering detection, and in particular relates to a method for testing the accuracy of underwater acousto-optic equipment. Background technique [0002] At present, with the development of underwater detection technologies such as sonar and underwater laser, the use of underwater acousto-optic equipment to detect underwater concealed projects and evaluate their construction quality has become a common detection method in the engineering field. Sonar and laser have a good display effect on underwater concealed projects, but underwater sound and light transmission is greatly affected by the water environment, such as water temperature will affect the speed of sound wave propagation, turbidity will affect the effect of light transmission, etc. The accuracy of the equipment is all in a certain range or beam angle, and the specific accuracy value of the geometric size is not given, and the data finally given...
