The invention relates to the technical field of image detection, in particular to a fusion method for polarization angle images of different wavebands based on multi-scale transformation. The method comprises the following steps: acquiring at least two image groups with detection wavelengths belonging to different wavebands, wherein each image group comprises radiation intensity images which are acquired under the conditions of the same detection wavelength and the same field of view and the condition that polarization wire grating directions in front of a lens of a detector are 0 degree, 45 degrees, 90 degrees and 135 degrees respectively; registering the image groups to obtain a registered target scene image group; based on the registered target scene image group, respectively calculating polarization angle images corresponding to different detection wavelengths; and based on multi-scale transformation, fusing the polarization angle images corresponding to different detection wavelengths to obtain a fused polarization angle image. The method can improve the accuracy of the polarization angle images of a target and a scene.
Description
technical field [0001] The present invention relates to the technical field of image detection, in particular to an image fusion method based on multi-scale transformation with different polarization angles, a target detection method, computer equipment, and a computer-readable storage medium. Background technique [0002] The polarization angle image mainly improves the target detection ability through the details such as the outline and edge of the target, but the information it can provide is relatively limited, especially for complex scenes, the environmental radiation may affect the detector to accurately obtain the polarization angle image of the target scene, and then affect to the target detection effect. [0003] Therefore, in view of the above deficiencies, it is necessary to provide a technical solution capable of improving the accuracy of the polarization angle image of the target scene. Contents of the invention [0004] The object of the present invention is...
