Abstract

The problems caused by the cavitation bubble and caused many adverse effects on the ship propeller, hydraulic machinery and equipment. In order to research the production mechanism of cavitation bubble under different conditions, cavitation bubble zone parameter fine measurement and analysis technology is indispensable, this paper adopts a non-contact measurement method of optical autonomous construction of binocular stereo vision measurement system according to the characteristics of cavitation bubble, the texture features are not clear, transparent and difficult to obtain, 3D imaging measurement of cavitation bubble using composite dynamic lighting, and 3D reconstruction of cavitation bubble region and obtained the characteristics of more accurate parameters, test results show that the cavitation bubble characteristics of the fine technology can obtain and analyze cavitation bubble region and instability.
