Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings of the description.

[0020] Step 1: Use laser focusing technology to obtain continuous sample slices. The selection of sample images is carried out under the same magnification and the same lighting conditions, and the intervals between slices are continuous and the same. Perform a series of operations such as grayscale, denoising, and enhancement on the collected original image set.

[0021] Step 2: Extract the reconstruction target from the background, which can not only shorten the reconstruction time, but also improve the accuracy of the reconstruction model. After the fiber is extracted from the background, its coordinates, shape, and normal vector information must also be stored. Specific steps are as follows:

[0022] (1) According to the difference of the gray level, the threshold segmentation is adopted to highlight the contrast between the fiber and the backg...

Abstract

The invention discloses a solid fiber feature detection method based on three-dimensional information, and belongs to the technical field of fiber solid three-dimensional reconstruction. According to the invention, the method comprises the steps: acquiring continuous fiber solid slice images, employing the digital image processing related knowledge for preprocessing the images, and segmenting a background from a reconstructed target; detecting features of reconstructed targets in a certain field of adjacent slice images by using a solid fiber feature detection algorithm, and matching the targets with high feature similarity; and building a three-dimensional reconstruction platform, and outputting a solid-state fiber reconstruction model by using a three-dimensional reconstruction algorithm. According to the method, the technical problem that the physical property of the fiber solid is difficult to observe is solved, and the accuracy of the reconstructed solid fiber model is improved.

Description

technical field [0001] The invention relates to the reproduction of the distribution of a linear structure represented by fibers in a solid space through a three-dimensional reconstruction method of feature detection. Background technique [0002] Due to the opacity of solids, common optical methods cannot obtain their complete structural information. The traditional analysis of solid tissue generally infers its three-dimensional spatial structure through two-dimensional photos, but this method of estimation mainly relies on experience and subjective factors, which makes the inferred three-dimensional spatial structure different from the real situation. Therefore, eliminating this discrepancy requires a more precise, less subjective, more scientific approach. [0003] Three-dimensional reconstruction technology can solve the above problems very well. In medicine, nuclear magnetic resonance and other methods are used to obtain specific physical information and reconstruct al...
