Embodiment Construction

[0057] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0058] Such as figure 1 As shown, in one embodiment, an application environment diagram of a 3D display method of a radiation field is provided, and the application environment diagram includes a collection device 110 and a terminal 120. The collection device 110 can communicate with the terminal 120. The collection device 110 is placed in a real radiation scene (nuclear power plant) to collect radiation source item data in the scene, such as radiation source distribution information, radiation source nuclide, and nuclide activity. The collection device 110 sends the collected radiation sour...

Abstract

The invention relates to a 3D display method of a radiation field. The method includes the following steps that: radiation source item data collected from a real radiation scene and a pre-constructedthree-dimensional scene model are coupled, so that a three-dimensional radiation field model can be obtained; a radiation source identifier specified by a user, in the three-dimensional scene model, is obtained, and a device identifier corresponding to the radiation source identifier is searched, the outer contour of the device identifier is a target projection surface; distance information inputted by the user is acquired, a to-be-displayed surface wrapping the target projection surface is determined according to the distance information; the sub-point sets of the to-be-displayed surface areselected from all point sets included in the to-be-displayed surface, wherein the selected sub-point sets can be accommodated by the target projection surface; and the radiation dose rate of all points in the sub-point sets is calculated according to the three-dimensional radiation field model, and the calculated radiation dose rate of all the points in the sub-point sets is projected onto the target projection surface so as to be displayed visually. The method of the invention can display of the radiation level of the radiation field in a 3D realistic manner.

Description

Technical field [0001] The present invention relates to the technical field of radiation protection, in particular to a 3D display method and device for a radiation field. Background technique [0002] In nuclear power plant operation, overhaul, maintenance and difficult nuclear decommissioning work, radiation protection is the key to safe operation of the nuclear industry. The key to radiation protection is to visually display the radiation field in the environment of nuclear facilities clearly and without blind spots. [0003] The traditional visual display of the radiation field generally displays the 3D of the radiation field in 2D form of two-dimensional slices, which can only display the radiation field information on a certain section, and cannot distinguish the front and rear positions of the radiation field, and cannot achieve any angle in all directions. 3D display effect. Summary of the invention [0004] Based on this, it is necessary to address the above-mentioned pro...
