Abstract

The embodiment of the invention discloses a method for eliminating a vignetting phenomenon in surgical microimaging, and relates to the technical field of image processing, and the method comprises the steps: obtaining a response function and a maximum illuminance ratio of a surgical microimaging system; constructing a vignetting compensation model; correcting the vignetting compensation model; obtaining the vignetting intensity of a microsurgery image, and setting a vignetting compensation threshold value and a gamma correction threshold value, wherein the vignetting compensation threshold value is larger than the gamma correction threshold value; and judging the size relationship between the vignetting intensity and a vignetting compensation threshold and the gamma correction threshold,and carrying out iterative correction to obtain an output image without a vignetting effect. According to the embodiment of the invention, the problem that a vignetting phenomenon in the existing surgical microimaging influences an imaging effect can be solved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of image processing, and in particular to a method for eliminating vignetting in surgical microscopic imaging. Background technique [0002] In an optical imaging system, the amount of light entering an object point farther away from the optical axis gradually decreases relative to an object point near the optical axis, resulting in a non-linear attenuation of the illuminance of the image plane from the center of the optical axis to the edge. This phenomenon is called vignetting. effect. Surgical microscopic imaging is more and more widely used in the field of microsurgery, and the optical vignetting effect directly affects the image quality of the surgical microscopic imaging acquisition system, thus affecting the effect of surgical microscopic imaging. [0003] The existing solution has the following two methods, one is to narrow the imaging range according to the radius of the micro...
