Embodiment Construction
[0014] The invention provides an image fusion method, a photographing device and a movable platform system. figure 1 It is a system architecture diagram of the mobile platform system involved in the present invention. Such as figure 1 As shown, the movable platform system may include: a movable platform 11 and a shooting device 12 . Wherein, the photographing device 12 can be mounted on the movable platform 11 . It should be noted that the photographing device 12 may be fixedly arranged on the movable platform 11 , or the photographing device 12 may be a device independent of the movable platform 11 . Communication between the movable platform 11 and the photographing device 12 can be performed in a wireless or wired manner based on a communication protocol. The present invention does not limit the types of the movable platform 11 and the shooting device 12 . Optionally, the movable platform 11 may be a drone, an unmanned car, or the like. The drone may be a rotorcraft, e...

The invention provides an image fusion method, shooting equipment and a movable platform system. The image fusion method comprises the following steps: acquiring a flat field correction trigger signal; controlling the first image acquisition device to start a flat field correction function according to the flat field correction trigger signal so as to perform flat field correction on the first image acquisition device; in the flat field correction process, enabling the first image acquisition device to not output the infrared image; and in the flat field correction process, fusing the infrared image acquired by the first image acquisition device and the visible light image acquired by the second image acquisition device to obtain a fused image, and determining the fused image as the fused image in the flat field correction process before the flat field correction starting moment. According to the image fusion method provided by the invention, the flat field correction function is started in the image fusion process, so that the temperature measurement precision is improved, and the image fusion effect is improved.
Description
technical field [0001] The invention relates to the technical field of movable platforms, in particular to an image fusion method, a photographing device and a movable platform system. Background technique [0002] Image fusion refers to the synthesis of complementary information from multiple images of the same scene into one image, which has a more comprehensive and accurate description than any single-source image. [0003] Among them, the fusion of infrared and visible light images has been widely used due to its particularity in aerospace and monitoring convenience. Visible light sensors can collect reflected light with rich appearance information to better establish a discriminant model. The infrared sensor mainly captures the thermal radiation emitted by the object, which is not subject to illumination changes or concealment, so it can work day and night and overcome some obstacles to find the target. Infrared images have lower spatial resolution than visible light ...
