Embodiment 1
[0070] Please refer to figure 1 , an infrared temperature measurement correction method based on an infrared image, comprising the steps of:
[0071] S1. Receive an infrared temperature measurement request, and obtain videos captured by the camera at different room temperature environments;
[0072] S2. According to the corresponding video in each room temperature environment, perform temperature calculation based on infrared images to obtain multiple different room temperature values;
[0073] Wherein, performing the temperature calculation based on the infrared image according to the video corresponding to each room temperature environment includes: performing temperature calculation in a standard room temperature environment and a room temperature environment different from the standard room temperature environment. In this embodiment, the standard room temperature environment The room temperature environment is 25-27°C, and the temperature measured at the standard room te...
Embodiment 2
[0081] The difference between this embodiment and Embodiment 1 is that the steps for calculating room temperature from infrared images are further limited, specifically:
[0082] Please refer to Figure 4 , in this embodiment, the current infrared image frame of the video is obtained, and the infrared image frame is divided into four first image blocks, please refer to Figure 5 , according to the average temperature of the pixels in each first image block, the current temperature of each first image block is obtained, and the temperature of each first image block is sorted from large to small, and the last quarter is selected The image block with a temperature of 26.7°C is selected as the image block to be calculated; please refer to Figure 6 , the image block to be calculated is divided into 4 second image blocks, and the current temperature of each second image block is obtained according to the average temperature of the pixels in each second image block, and the tempera...
Embodiment 3
[0084] Please refer to figure 2 , an infrared temperature measurement and correction terminal based on infrared images, including a memory, a processor, and a computer program stored on the memory and operable on the processor, and the first embodiment is realized when the processor executes the computer program Or the various steps of the infrared temperature measurement correction method based on the infrared image in the second embodiment.
[0085] To sum up, the infrared image-based infrared temperature measurement correction method and terminal provided by the present invention, when receiving an infrared temperature measurement request, obtains the video captured by the camera at different room temperature environments, and according to the corresponding temperature in each room temperature environment The temperature calculation based on the infrared image is carried out on the video image frame to obtain multiple different room temperature values, and the temperature ...
