Ambient temperature setting (ambient temperature setting in the temperature measurement area) has a great
influence on the accuracy of temperature measurement, so please input the ambient temperature accurately
according to the actual situation.
2.2.1 Image registration
The system adopts the dual cursor synchronous display method of infrared video and visible video, but since the
infrared temperature camera and visible video camera have different field angles, it is impossible to make the two
cameras completely parallel in the installation, resulting in the position of the same target in the two videos looks
inconsistent. In order to accurately find the corresponding relationship between the infrared image and the visible
image, a video registration algorithm is added to the software. The mapping relationship between infrared region and
visible region can be obtained by registering the three pairs of alignment points in visible region and infrared
region. By this mapping relationship, the accurate coordinates of high temperature target coordinates in infrared image in
visible video can be calculated.
