[0037] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0038] like figure 1 As shown, the present invention provides a natural color fusion method based on color contrast enhancement, and its design principle is: obtain the fusion coefficient according to the pseudo-color fusion effect of the dual-band grayscale image; then, according to the brightness of each pixel in the infrared image to the center The average distance corrects the b-channel color transfer equation, and according to the linear and nonlinear color transfer effects, an appropriate expansion index factor is obtained; finally, the natural sense color fusion of the dual-band video is carried out using the determined fusion coefficient and expansion index factor, and the establishment In practical applications, it is beneficial for different observers to perceive the operation mode of the scene.
[0039] The present invent...
