Abstract

The invention relates to an optical fiber image correction method and device and a computer readable storage medium. The method comprises the steps of obtaining a current optical fiber image and an optical fiber center reference position; in the current optical fiber image, correcting the central position of each optical fiber unit in the current optical fiber image according to a position difference condition between the optical fiber central reference position and a target position determined based on a gray value in a neighborhood range of the optical fiber central reference position; and according to the currently determined brightness correction coefficient, performing brightness correction on the current optical fiber image of which the position correction is completed. Therefore, in the process of observing an object by using the microendoscope, not only can the optical fiber drift correction be quickly and efficiently realized on the acquired optical fiber image, but also the real-time parameter correction can be quickly and efficiently realized, so that the optical fiber image quality in the observation process is improved, the consistency of the optical fiber image quality is ensured, and the accuracy of subsequent diagnosis is improved.

Description

technical field [0001] The present disclosure relates to the field of image processing, and in particular, relates to an optical fiber image correction method, device, and computer-readable storage medium. Background technique [0002] Microendoscopes are widely used in medical observation and detection. Optical fibers and vibrating mirrors are important components of microendoscopes. A whole optical fiber is usually composed of tens of thousands of optical fiber units. Usually, each The center position of each fiber unit is fixed. In actual use, due to the limitation of the scanning accuracy of the galvanometer and the bending change of the optical fiber during use, it is impossible to ensure that each scan is at the exact same position when the end face is fixed. Therefore, as time changes, the scanning position of the galvanometer and the position of the fiber will change, and correspondingly, the center position of each fiber unit in a whole fiber will also change. Thi...

Problems solved by technology

Ideally, the centers of the optical fiber units in the same optical fiber are completely coincident at each moment in the same use process. However, if figure 1 As shown in , due to the fiber drift phenomenon, there is a certain pixel difference in the center position between the two moments

In the process of image reconstruction, it is necessary to determine the position of the center of each fiber unit to implement a fast degriding method, and the existence of fiber drift will make fiber information in the wrong position be extracted during fiber image processing, which greatly affects Image Quality

And the deviation of the gray value of the center of each fiber unit from each other will also significantly affect the image quality
