Intrinsic color restoration method based on visual acuity curve

Abstract

The invention discloses an intrinsic color restoration method based on a visual acuity curve, which comprises the steps of obtaining target radiation energy according to an infrared camera, and obtaining a target temperature on the basis by using a Stefan-Boltzmann law formula; substituting the target temperature into a Planck radiation law formula to obtain a radiation curve within a visible light range; and solving definite integrals within the visible light range according to visual acuity curve formulas of the human eyes to red, green and blue light and the Planck radiation law formula toobtain a red component, a green component and a blue component. According to the invention, a brightness curve within a visible light region corresponding to the target is inversely deduced accordingto a black-body radiation curve, and then integral computation is performed by combining a sensitivity curve of the human eyes for the color, thereby restoring the intrinsic color of the target, avoiding the loss or distortion of the color, thus improving the definition of an image, realizing high definition of image information and improving the recognition capability for the image information.

Problems solved by technology

[0004] The purpose of the present invention is to provide an intrinsic color restoration method based on the visual acuity curve, which deduces the luminance curve in the visible light region corresponding to the target according to the black body radiation curve, and then integrates the human eye's sensitivity curve to the color for integral calculation. Restore the intrinsic color of the target, and solve the problem that the existing network camera has poor recognition ability of the monitored image information, which causes the color to be easily lost or distorted, resulting in poor image clarity
