Problems solved by technology

The price of external thermometers represented by forehead thermometers is close to the people, but they need manual one-to-one close-range detection, which is not suitable for large-scale crowd temperature measurement. At the same time, there are certain errors in measurement accuracy, while thermal imagers can measure many Human body temperature data is suitable for large-scale rapid preliminary screening scenarios, but the price is high and the maintenance cost is high

Abstract

The invention discloses an infrared temperature measurement compensation method based on binocular camera ranging. The infrared temperature measurement compensation method comprises the steps of collecting human body image information by adopting a binocular camera, calculating the distance between the aperture center of the binocular camera and a human body, and compensating the temperature of aninfrared sensor. A binocular camera detection mode is adopted, the parallax of two images is calculated to obtain the distance between the human body and the sensor, an infrared temperature measurement software compensation algorithm is adopted to finally calculate the human body surface measurement temperature, the influence of the environment temperature on the measurement temperature is small,the precision is high, the performance is stable, and the deployment is more convenient.

Description

Technical field: [0001] The invention relates to the technical field of human body surface temperature measurement, in particular to an infrared temperature measurement compensation method based on binocular camera distance measurement. Background technique: [0002] In recent years, with the large-scale outbreak of public health incidents, in the process of epidemic prevention and control, various sensing technologies have played a vital role as technical means. Epidemic facilities are inseparable from the support of sensors, especially infrared temperature sensors, as the core components of body temperature measurement equipment, have attracted the attention of the industry. The price of the external thermometer represented by the forehead thermometer is close to the people, but it needs manual one-to-one close-range detection, which is not suitable for large-scale crowd temperature measurement. At the same time, there is a certain error in the measurement accuracy, while ...
