What is the reason why the infrared thermal image of the image taken by the infrared thermal imager does not coincide with the visible light image? How to make up?

There are two situations that can cause this problem:

1) out of focus;

2) The shooting distance is too close-each infrared thermal imager has two minimum focusing distances (infrared lens and visible lens respectively).

Only when the shooting distance is greater than the minimum focusing distance of the two lenses at the same time, the infrared and visible images can be completely merged, and the close-range shooting may have a picture dislocation.

When you find that the infrared thermal image is inconsistent with the visible image, you can use the image editing function of SmartViewR software to eliminate the deviation from the infrared image by moving the position of the visible image.
