Embodiment

[0053] like Figure 1 to Figure 3 As shown, the present invention provides an augmented reality method and system for gamma radiation sources to ensure social order in important areas such as ports, large conferences, and major events, and to realize effective supervision of radiation sources. In this embodiment, only 6 NaI(T1) scintillator detectors are set in three-dimensional space as an example for illustration, and other situations where 4 or more organic or inorganic scintillator detectors are set are the same as the process of this embodiment, and will not be described here. I will repeat.

[0054] Select a point in the three-dimensional space as the reference origin of the Cartesian coordinate system, and the equivalent three-dimensional position coordinates of the six scintillator detectors are shown in Table 1:

Abstract

The invention discloses a gamma radioactive source augmented reality method and system, and mainly solves the problems existing in the prior art that accurate locating and tracking of the moving unknown radioactive source and real-time display of the radioactive source cannot be realized. The system comprises at least four scintillator detectors which are discretely distributed and configured in atwo-dimensional or three-dimensional space; a camera which is arranged at the edge of the space area and used for performing video image photographing of the space; an industrial control computer which is connected with the scintillator detectors and the camera and used for acquiring the counting rate and the energy spectrum detected by the scintillator detectors to realize nuclide identification, locating and surface dose rate calculation of the radioactive source; and a terminal machine which is connected with the industrial control computer and used for transformation of the three-dimensional locating coordinates and the two-dimensional video image coordinates, fusion of the radioactive source icon and the video image and storage and display of the video image and the radioactive source parameters. The gamma radioactive source augmented reality method and system have the advantages of accurate locating of the radioactive source, nuclide identification, surface dose rate calculation, continuous tracking and visual real-time image display.

Description

technical field [0001] The invention relates to the field of nuclear technology, in particular to a method and system for augmenting reality of gamma radiation sources. Background technique [0002] With the continuous development of nuclear energy technology, nuclear energy, as an important part of sustainable clean energy, has been gradually used in power generation, submarines and other fields due to the huge energy released by nuclear energy fission and the absence of air pollutants in the nuclear energy reaction process. However, nuclear energy also has huge risks, such as radiation, radioactive waste disposal, etc., which bring economic benefits to society, but also cause considerable troubles to society and the ecological environment. Because the radiation of its radioactive source will affect the normal operation of electronics and communications, it is strictly forbidden to carry radioactive materials in the transportation industry, especially in the fields of ports...
