METHOD AND DEVICE FOR DUAL LIGHT FUSION

WIPO Patent Application WO/2020/211576

A1

A method and device used for dual light fusion, the method comprising: determining a first radial distance of an objective lens of a thermal imager currently relative to a preset position, wherein the preset position is a preset position in the thermal imager used for calculating the amount of radial movement of the objective lens; on the basis of the first radial distance, determining the current object distance of a target object; on the basis of the current object distance, obtaining an infrared image of the target object; on the basis of the current object distance, obtaining dual light fusion parameters pre-existing in the thermal imager and corresponding to the current object distance; and on the basis of the dual light fusion parameters, performing dual light fusion on the infrared image and a visible light image of the target object. In the method in the embodiments of the present application, the thermal imager obtains the first radial distance that represents the amount of movement of the objective lens, and may then determine the current object distance by means of the first radial distance. Dual light fusion is automatically completed according to the current object distance, thereby improving the user experience.
