[0004] Although the existing file storage method stores the completed target temperature information, which is convenient for post-event image processing and analysis, it also takes up a large amount of storage space. In some occasions where fast transmission is required and the communication bandwidth is very narrow (or the storage space is very small) Occasions), while wasting storage space, it also makes it impossible to transmit data in time

[0057] Table 1 Infrared general data file storage format
[0058]Taking a 320*240 size image as an example, in a 320*240 size JPEG infrared image, the formula Gray=R*0.299+G*0.587+B*0.114 is used to convert the color image into a grayscale image of 0-255 level ( See figure 2 );
[0059] In the grayscale image above, the grayscale value of the brightest point is 255, and the grayscale value of the darkest point is 0;
[0060] In the grayscale image matrix (320*240 points) in the above figure, the grayscale value of any point can be obtained. At the same time, through the coordinates of the point, the temperature value of the point can be obtained. (According to the data structure of Table 1, after the position of any point is determined, the temperature of the point can be obtained from the IRData data segment). See image 3 , the grayscale of the highest point is 255, and the temperature is 60.8℃;
[0061] In the grayscale image matrix of the inf...

The invention discloses an infrared thermogram data compression storage method, which belongs to the technical field of power grid power transmission and transformation equipment state monitoring systems, and comprises the following steps: converting an infrared color image into a gray level image of 0-n levels, and obtaining a gray level numerical value g of any point through a gray level image matrix; obtaining a temperature value of the point through the coordinate of any point; obtaining a group of temperature data with the number of n+1 through the gray level image matrix of the infraredcolor image, and attaching two ASCII code characters ' G0 'behind the infrared color image JPEG format file; and attaching the temperature array to an infrared color image JPEG format file to serve asan additional data segment of the JPEG format file. According to the method, the size of the infrared thermogram file can be effectively reduced, and the temperature of any point can be restored in astationary point mode while the target infrared thermogram can be seen. The storage capacity of the disk is greatly improved, and the transmission rate of the infrared thermogram is greatly improved.
Description
technical field [0001] The invention relates to the technical field of a state monitoring system for power transmission and transformation equipment in a power grid, and more specifically, relates to a method for compressing and storing infrared heat map data. Background technique [0002] Infrared heat map data is an important basic data for analyzing the working status of equipment. The standard format of infrared heat map data files is stipulated in the electric power industry standard of the People's Republic of China "DL / T664-2016 Application Specification for Infrared Diagnosis of Live Equipment". [0003] In the existing infrared heat map data format file, the picture information in JPEG format is first stored, and then the time, version, manufacturer and other information of infrared thermal image collection are stored in the attachment data segment of the JPEG file, and the infrared temperature value is also stored. bitmap data. Taking an image file collected by a ...
