Embodiment 1

[0058] For ease of understanding, see figure 1 , Embodiment 1 of a three-dimensional visualization method for power equipment fused with infrared temperature measurement images provided by the present application, including:

[0059] Step 101: Segment the corresponding infrared power equipment image in the infrared temperature measurement image based on the preset section of the three-dimensional texture image of the power equipment.

[0060] The three-dimensional texture image of the power equipment includes multiple different faces of the power equipment, from which different sections are extracted, that is, a certain face of the power equipment, which is used for the segmentation of the equipment in the two-dimensional infrared temperature measurement image, and the Electrical equipment is roughly separated. It can be understood that the infrared temperature measurement image is an image obtained through a series of preprocessing in the early stage, such as denoising and o...

Embodiment 2

[0072] For ease of understanding, see figure 2 , the present application provides a second embodiment of a three-dimensional visualization method for electric power equipment fused with infrared temperature measurement images, including:

[0073] Step 201. Obtain pixel data of an infrared temperature measurement image, and determine a candidate area according to a rectangular pixel array formed by the pixel data.

[0074] The infrared temperature measurement image can be filtered before the specific segmentation to effectively remove noise interference. Generally, there are more Gaussian noises in the image. Therefore, the Gaussian filter can be used to perform Gaussian filtering on the infrared temperature measurement image. Processing, the specific two-dimensional Gaussian filter function is expressed as:

[0075] F(x,y)=f(x,y)·G(x,y)

[0076]

[0077] Among them, e is the rotational symmetry coefficient of the image, f(x, y) is the infrared temperature measurement ima...

Abstract

The invention discloses a power equipment three-dimensional visualization method and device fused with an infrared temperature measurement image. The method comprises the following steps: segmenting an infrared power equipment image in an infrared temperature measurement image based on a power equipment three-dimensional texture image section; extracting key points from the power equipment three-dimensional texture image and the infrared power equipment image by adopting an SIFT algorithm, performing local image matching according to the calculated Euclidean distance between the key points in the infrared key point image and the three-dimensional texture key point image, and obtaining a power equipment infrared local image; performing three-dimensional formation on the infrared local graph of the power equipment into a three-dimensional infrared image according to a preset rotation translation matrix; performing image fusion on the three-dimensional infrared image and the three-dimensional texture image of the power equipment based on the edge information and the fusion weight to obtain a three-dimensional infrared texture image; and carrying out visual display on the three-dimensional infrared texture image. The technical problems that in the prior art, visualization is single, intuition is poor, and richer power equipment information cannot be provided can be solved.

Description

technical field [0001] The present application relates to the technical field of three-dimensional image display, in particular to a method and device for three-dimensional visualization of electric power equipment fused with infrared temperature measurement images. Background technique [0002] With the continuous progress and development of science and technology, 3D modeling technology is widely used in substations. The 3D model displays the size, location, structure and other information of the substation equipment in a visual way. With the upgrading of the application of 3D technology, it is necessary to provide substation staff with richer information display on the 3D model. It is necessary to enhance the intuition and visualization of abstract spatial information, so as to assist the operation and maintenance personnel to make quick decisions in their work. and precise judgment. [0003] The existing visual display of power equipment is either to obtain infrared th...
