Intelligent high-precision bubble three-dimensional shape obtaining system

Abstract

The invention provides an intelligent high-precision bubble three-dimensional shape obtaining system, which comprises a virtual binocular three-dimensional visual photo taking platform, a steel wire rope ascending and descending table and a bubble three-dimensional shape rebuilding algorithm, wherein the virtual binocular three-dimensional visual photo taking platform comprises an article carryingplatform, a four-side plane mirror and a high-speed camera; a shooting object respectively forms images on the high-speed camera through the reflection of the plane mirrors symmetrical at the left side and the right side; the steel wire ascending and descending table is used for carrying the virtual binocular three-dimensional visual photo taking platform to perform vertical lifting and descending; a driving device comprises a step motor and a control system; the control system is used for controlling the ascending and descending mechanism. The bubble three-dimensional shape rebuilding algorithm module supposes each layer of the bubble is in an ellipse shape, determines the major and minor axis of the ellipse according to the bubble edge information obtained on the basis of image processing; finally, the ellipses are laminated layer by layer. The system can be used for performing high-precision tracking shooting on the moving process of bubbles in fluid with different flow speeds andthe bubble three-dimensional shape obtaining.

Description

technical field [0001] The present invention relates to the technical field of high-precision acquisition of the three-dimensional shape of bubbles in fluids, and in particular relates to an intelligent high-precision three-dimensional shape acquisition system of bubbles. Background technique [0002] The thorium-based molten salt reactor has become one of the six candidate reactor types for the fourth-generation reactor nuclear energy system due to its advantages such as good safety, long-term supply of nuclear fuel, minimization of nuclear waste, high production capacity, and physical nuclear proliferation resistance. The energy generated by thorium fuel of the same quality is 200-250 times that of uranium fuel, and the reserves of thorium resources in the earth's crust are three times that of uranium resources. Especially in China, thorium resources rank second in the world, and its reserves are about It is 6 times that of uranium resources, and thorium-based molten salt r...
