Remote appearance inspection and measurement method and system for nuclear power plant containment

Abstract

The invention provides a remote appearance inspection and measurement method and system for a nuclear power plant containment. The method comprises the following steps: photography scheme pre-designing: generating an optical camera station site and a photography scheme; remotely automatic photographic data acquisition: orienting remote photography equipment, calibrating the remote photography equipment, acquiring an appearance image of the containment through the remote photography equipment, transmitting the image to the main control end in real time through a wireless network, and enabling the main control end to transmit a working instruction to the photography equipment through the wireless network; and image data processing: acquiring a panorama expanded view and defect information of the appearance of the containment. A plurality of sites for remote photography are set around a large range of the nuclear power plant containment to automatically acquire a high-resolution containment appearance image to finish data acquisition so as to cover the containment appearance panorama at 360 degrees, and an appearance defect can be checked and measured. The field work scheme for automatically remote photography can acquire a high-precision panorama image of the containment, and the labor operation can be greatly saved, therefore, the working efficiency is greatly improved, and the remote appearance inspection and measurement method is safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of photogrammetry, in particular to a method and a system for obtaining appearance images of nuclear power plant containment shells through remote photography equipment, and inspecting and measuring appearance surface defects. Background technique [0002] The development level of cutting-edge industries symbolizes the speed, scale and level of national economic modernization, and the safety of industrial production is the premise of development. The nuclear power industry has been widely recognized for its huge advantages of economy and cleanliness, and safety has become an important prerequisite for the development of the nuclear power industry. As a key building to ensure the safe production of nuclear power—the nuclear power plant containment (such as figure 1 ), its robustness, durability, compression resistance, heat insulation and other properties must meet high standards, and the defects of the cont...

AI Technical Summary

Problems solved by technology

The working environment and plant structure of the nuclear power plant are complex. The containment vessel is in the form of a double-layer standard cylindrical shell with a large diameter. Various plants are built on the shell, which becomes an obstacle to the photography environment.
