Embodiment 1

[0023] figure 1 A flow chart of an image fusion method provided by the first embodiment of the present invention is shown, and the details are as follows:

[0024] Step S101, acquiring visible light images and infrared remote sensing raw data.

[0025] Among them, the visible light image refers to the image that can be recognized by the human eye. The visible light image can be obtained by the CCD camera, and the original infrared remote sensing data can be obtained by the sensor used for infrared remote sensing. In the embodiment of the present invention, visible light images and infrared remote sensing raw data are acquired synchronously.

[0026] Step S102, acquiring a first infrared pseudo-color image based on the infrared remote sensing raw data.

[0027] In the embodiment of the present invention, the infrared remote sensing data may be converted into the first infrared pseudo-color image by adopting but not limited to linear transformation.

[0028] Optionally, the s...

Embodiment 2

[0056] figure 2 It shows a flow chart of an image fusion method provided by the second embodiment of the present invention, which is described in detail as follows:

[0057] Step S201, acquiring visible light images and infrared remote sensing raw data.

[0058] Step S202, based on the infrared remote sensing raw data, acquire a first infrared pseudo-color image.

[0059] Step S203, according to the parameter interval of the preset temperature filtering parameter, filter the first infrared pseudo-color image to obtain a second infrared pseudo-color image.

[0060] In this embodiment, for the specific steps from step S201 to step S203, refer to step S101 to step S103 in the first embodiment, which will not be repeated here.

[0061] Step S204, performing target recognition based on the second infrared pseudo-color image, and extracting an infrared target image. For example, when the target object is a person, target recognition is human figure recognition.

Embodiment 3

[0076] Corresponding to the image fusion method described in the above embodiment, image 3 A structural block diagram of an image fusion device provided by an embodiment of the present invention is shown, and for convenience of description, only parts related to the embodiment of the present invention are shown.

[0077] refer to image 3 , the image fusion device includes: an image data acquisition unit 31, a first infrared pseudo-color image acquisition unit 32, a second infrared pseudo-color image acquisition unit 33, and a fusion unit 34, wherein:

[0078] The image data acquisition unit 31 is configured to acquire visible light images and infrared remote sensing raw data. Among them, the visible light image refers to the image that can be recognized by the human eye. The visible light image can be obtained by the CCD camera, and the original infrared remote sensing data can be obtained by the sensor used for infrared remote sensing. In the embodiment of the present inv...

Abstract

The present invention is applicable to the technical field of image processing, and provides an image fusion method and apparatus. The method comprises: acquiring a visible light image and infrared remote sensing raw data; acquiring a first infrared pseudo color image based on the infrared remote sensing raw data; according to a parameter interval of preset temperature filtering parameters, performing filtering processing on the first infrared pseudo color image to obtain a second infrared pseudo color image; and fusing the second infrared pseudo color image with the visible light image to obtain a target fused image. According to the method provided by the present invention, people can efficiently and accurately identify the target object in a facilitated manner.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to an image fusion method and device. Background technique [0002] Visible light images are similar and vivid descriptions or portraits of objective objects in the material world, and are the most commonly used information carriers in human social activities. Infrared rays are one of the many invisible rays in the sun's rays. Thermal infrared images are converted images obtained by collecting and recording infrared radiation emitted by objects by thermal infrared cameras. Infrared thermal images obtained by using infrared rays are widely used used in various fields. Due to the various limitations of the image sensor's own physical characteristics, imaging mechanism, and viewing angle, a single image sensor is often unable to extract enough information from the scene. The fusion of visible light images and infrared images can adapt to various illumination envir...
