Embodiment Construction

[0053] In order to make the technical means that the present invention realizes, creation feature, reach purpose and effect easy to understand, further set forth the present invention below.

[0054] Such as figure 1 A nuclear fuel rod size detection system based on telecentric optics shown includes a detection platform 100 and a positioning installation module 200, an image acquisition module 300, an illumination module 400 and an industrial computer 500 arranged on the detection platform 100. The positioning installation module 200 includes a fixed pressing block 210 installed on the test platform 100 and a movable pressing block 220 hinged and fastened on the fixed pressing block 210. The fixed briquetting block 210 cooperates with the movable briquetting block 220 to realize the positioning installation of the standard pipe rod (not shown in the figure) or the nuclear fuel rod 600 to be tested, and the positioning installation of the standard pipe rod (not shown in the fig...

Abstract

The invention discloses a nuclear fuel rod dimension detecting method and system based on telecentric optics. The method comprises filtering an original image by an adaptive median filter and extracting the edge of the filtered image by using an anti-noise grayscale morphology operator, scanning the edge image of the nuclear fuel rod, and unfolding the edge; and detecting the external dimension ofthe nuclear fuel rod by a telecentric imaging system. The nuclear fuel rod dimension detecting system can overcome the far-smallness near-bigness phenomenon of a traditional pinhole imaging system, can clearly acquire the contour shape of an isolation block in the middle part of the nuclear fuel rod, and has the advantages of small distortion, clear edges and a large depth of field. Compared witha conventional edge detection algorithm, the algorithm for detecting the contour edge of the nuclear fuel rod by using dilation-erosion edge detection operator resistant positive and negative pulse noise is good in anti-noise ability and accurate in edge location.

Description

technical field [0001] The invention relates to the field of intelligent measurement and detection, in particular to a method and system for detecting the size of nuclear fuel rods based on telecentric optics. Background technique [0002] With the rapid development of society and rapid industrialization, traditional fossil energy sources such as oil, natural gas, and coal are gradually being exhausted. At the same time, environmental problems such as air pollution, water pollution, and soil pollution are becoming more and more serious. It is urgent to increase the utilization rate of new clean energy. [0003] The appearance and size of nuclear fuel elements will vary according to the needs of the reactor, but their essence is composed of nuclear fuel core and cladding. Nuclear fuel elements are an important part of nuclear reactors, which form the basic elements of nuclear reactors and provide energy for nuclear power generation. At the same time, nuclear fuel elements ...
