Real-time large-scale image synthesis algorithm of microscopic system

Abstract

The invention discloses a real-time large-scale image synthesis algorithm of a microscopic system, and relates to the technical field of microscopic optical imaging and image processing, the algorithm adopts a multi-thread parallel image acquisition mode, and is convenient and rapid; according to the method, features are only extracted from a region of interest (ROI) by using a multi-thread technology, so that calculation of feature points which do not contribute to a synthesized image is avoided, the calculation time and the calculation steps are greatly reduced, the influence of wrong feature points is avoided, and the accuracy and the efficiency of extracting the feature points are improved; in a GPU acceleration environment, a matching pair set of each image is solved in parallel according to a dense-to-sparse method, so that calculation of sparse regions of feature points is greatly reduced, matching of dense feature sets is preferentially ensured, and processing efficiency and precision are improved; the optimal matching pair is screened based on the length and slope of the reference line, and the calculation process is simplified; the algorithm is easy to realize real-time large-scale image synthesis of the microscopic system.

Description

technical field [0001] The invention relates to the technical field of microscopic optical imaging and image processing, in particular to a real-time large-scale image synthesis algorithm for a microscopic system. Background technique [0002] Due to the limitations of optical imaging principles, the field of view of traditional optical microscopes is limited to a relatively small range, and the field of view of most traditional optical microscopes (10×) is limited to less than 2.5mm, and relatively awkward scanning is used The method (lens scanning, turntable scanning) and the way of moving the stage are used for microscopic imaging. This not only brings great inconvenience to the observation of a specific area of ​​the sample, especially the control of local details in the area of ​​interest, but also is powerless to quickly observe small objects in a large area. Processing time in the microscope field is precious, and it is unscientific to scan and go back to process the...

Problems solved by technology

However, although there are already image synthesis algorithms that can be used for microscopic imaging, traditional image synthesis algorithms either cannot perform real-time imaging due to their slow speed, and often adopt the method of collecting and saving images before selecting post-processing; Due to low precision and other reasons, large-scale imaging cannot be formed, which has caused great trouble to our real-time large-scale microscopic imaging
