Abstract

The invention discloses an infrared temperature measurement correction method based on infrared images and a terminal, and the method comprises the steps of: acquiring videos shot by a camera in different room temperature environments when an infrared temperature measurement request is received, and carrying out temperature calculation based on the infrared images according to a video image framecorresponding to each room temperature environment to obtain a plurality of different room temperature values, acquiring a plurality of different room temperature values and the temperatures measuredat the plurality of different room temperature values to obtain a temperature error correction function, and correcting the temperature measured through infrared temperature measurement according to the temperature error correction function. The temperature of each image frame is calculated through the infrared images, the indoor temperature can be precisely measured, the temperature error correction function can precisely obtained, and the temperature measured through infrared temperature measurement is corrected through the temperature error correction function, therefore the high-precisionhuman body temperature is obtained. The room temperature is calculated by using the infrared images, and the temperature measurement precision can be ensured while the calculated amount is small, so that the influence of an environment temperature factor on the human body temperature measurement precision is reduced.

Description

technical field [0001] The invention relates to the technical field of infrared temperature measurement, in particular to an infrared image-based correction method for infrared temperature measurement and a terminal. Background technique [0002] Because thermal infrared temperature measurement is non-contact measurement and fast measurement speed, it is often used as a quick screening in quarantine. Atmospheric thermal radiation exchange, i.e. high or low ambient temperature, can cause deviations in the measurement results. In the prior art, one is to manually input the ambient temperature to correct the measurement results, and the other is to solve and correct all the measurement results in a day so that the measurement results are consistent, thereby eliminating the influence of the ambient temperature. However, the former has a poor correction effect due to the single data; while the latter requires a large enough data set and has a huge amount of calculation. Conten...
