Method and system for adjusting offset of optical fiber display area

Abstract

The present invention provides an optical fiber display area offset regulation method and system. The method comprises: obtaining an image sensor target surface image; extracting edge information in an image to obtain edge information of an electrode bar in the image; performing linear data extraction according to the edge information of the electrode bar, and calculating a straight line intersection to determine the position (pX, pY) of the tip of the electrode bar; calculating a horizontal offset according to the column position pY of the tip of the electrode bar and the width of an optical fiber display area to regulate the horizontal position of the optical fiber display area in the image; and determining the initial offset position of a vertical offset according to the row position pX of the tip of the electrode bar, or the row position pX of the tip of the electrode bar and the height of the optical fiber display area, and taking a certain amount as the vertical regulation offset to regulate vertical offset so as to gradually regulate the vertical position of the optical fiber display area in the image until the brightness of the optical fiber display area accords with an established standard. The offset can be subjected to more rapid and more accurate regulation so as to optimize continuous loss to certain extent.

Description

technical field [0001] The invention relates to the technical field of optical fiber fusion splicing, in particular to a method and system for adjusting the offset of an optical fiber display area. Background technique [0002] In fiber fusion splicing technology, the diameter of the bare fiber is generally 125 μm, and the diameter of the fiber core used to transmit signals is less than 10 μm. If a camera is used to directly image the bare fiber on the target surface of the CMOS image sensor, the imaging size of the bare fiber If it is too small, it occupies very few pixels, and the details of the image are relatively few, which brings great difficulty to the later image recognition and processing. In the practical application of the optical fiber fusion splicer, by amplifying the bare optical fiber, see figure 1 , that is, a microscope M is added between the bare fiber V and the camera C, so that the actual imaging size of the bare fiber V on the CMOS target surface will i...

Problems solved by technology

So, how to capture image data with a specified size and uniform brightness from the CMOS target surface? The existing technology is to manually adjust the CMOS offset to intercept image data with a specified size and uniform brightness. Manually adjusting the CMOS offset is not only inefficient, but also prone to human error, which affects the connection loss.
