Microscopic image splicing method and system

Abstract

The invention discloses a microscopic image splicing method and system, and belongs to the field of image processing, and the method comprises the steps: controlling an image collection unit to successively translate and collect microscopic images at all positions of a sample, and enabling the size of an overlapping region of adjacent images to be equal to a set value; searching source feature points in the source image overlapping area, determining corresponding target feature points in the microscopic image corresponding to the target image overlapping area, and the target image is the microscopic image after current splicing; searching all feature points in a window taking any target feature point as the center, calculating the distance between the corresponding source feature point and each feature point in the window, and judging whether the source feature point is matched with the feature point corresponding to the minimum distance according to the ratio of the minimum distance to the second minimum distance; splicing the source image and the target image according to a matching result, and taking the spliced image as the target image; and so on, until the last microscopic image is spliced to the target image. The calculated amount is small, the consumed time is short, and the splicing efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the field of image processing, and more specifically relates to a microscopic image splicing method and system. Background technique [0002] In many scientific research fields, it is necessary to observe the microscopic morphology of the target to be detected, such as medical, biological, material and precision manufacturing and other fields. In order to obtain the microscopic shape of the target to be detected, a camera and lens with sufficient resolution are needed to obtain a suitable observation image. However, the increase in resolution will inevitably lead to a decrease in the field of view of the camera, which leads to direct observation of only a part of the target to be detected. On the premise of ensuring a suitable resolution, directly increasing the size of the photosensitive element of the camera will not only greatly increase the cost, but also cannot solve the demand for a larger observation range, which requir...
