Problems solved by technology

Such frequent freezing and unlocking of the image will affect the measurement efficiency, and will also cause the measurement mark to disappear (due to the switching of the image between the frozen and non-frozen states), when a large number of fibers appear in the same field of view, the user may be confused Forget which fibers have been tested before due to the disappearance of measurement marks, resulting in repeated measurements, which ultimately affects the accuracy of the data

Abstract

The invention provides a fiber-measurement non-freezing field-of-view replacement automatic-determination algorithm. The algorithm includes: step 1, setting a judgment variable, and starting a determination thread, which is used for recording whether image field-of-view contents change, and starting a corresponding processing thread, wherein the changes include changes generated by focusing and changes generated by field-of-view switching or moving; and step 2, starting the determination thread for image field-of-view content change determination after image preprocessing, firstly, adopting center-of-gravity and correlation determination, according to a determination result, determining whether a high-frequency component of a compressed image is used to continue determination, finally, sending a determination result to a main thread, and according to the determination result, deciding whether field-of-view replacement action is executed. Through the algorithm, fiber measurement efficiency can be improved, and repeated measurement can be eliminated.

Description

technical field [0001] The invention belongs to the technical field of fiber measurement, and in particular relates to an automatic determination algorithm for non-freezing and field-of-view changes in fiber measurement. Background technique [0002] The traditional microscope linking camera to measure fiber fineness is carried out in the state of image freezing, that is, if you need to measure a fiber in the current field of view, you need to freeze a current field of view to become an image displayed in the window, and then perform Measurement. If there are other fibers in different positions in this field of view, but not in the best focus state, it is necessary to unfreeze the current field of view to make it dynamic in the window, so as to observe the focusing state in real time, when another fiber is to be tested After the fibers are cleared, the field of view is frozen again for measurement. Such frequent freezing and unlocking of the image will affect the measureme...
