Abstract

The embodiment of the invention provides an infrared anti-interference method and device based on spectral characteristic difference. The method comprises the steps that when a target object is located in the air, acquiring an infrared image sequence containing infrared interference and corresponding to the target object; performing filtering and bicolorimetering on the infrared image sequence based on a moving pipeline, and determining a target position of the target object; tracking the target object based on the target position to obtain a tracking result; and positioning the target objectaccording to the tracking result. According to the embodiment of the invention, the method can effectively irons out the defect that a single-target tracking method cannot detect a target again afterthe target is lost, can effectively alleviate the impact on the target positioning from a background edge, and achieves the quick estimation of the target position between continuous frames.

Description
