Embodiment Construction

[0024] The specific embodiment of the present invention is described below in conjunction with accompanying drawing:

[0025] step:

[0026] 1. Image feature point extraction

[0027] 1.1 Image acquisition:

[0028] Obtain book illustrations in the form of scanners or photographs.

[0029] 1.2 Image preprocessing:

[0030] S1: Brightness correction: Add or subtract a specific value to the RGB value of each pixel at the same time.

[0031] S2:: Grayscale transformation: Histogramize the grayscale image, calculate the number of pixels at each pixel level; form a cumulative histogram, and then perform histogram equalization; create a new brightness lookup table.

[0032] S3: smoothing processing, the length and width of the image are ×2, and Gaussian filtering is used for smoothing.

[0033] 1.3 Surf algorithm implementation and feature point generation:

[0034] This part is mainly divided into 5 steps:

[0035] S1: Construct the Hessian matrix, replace the function value...

Abstract

The invention relates to an augmented reality based mobile platform three-dimensional biomolecule display system and an augmented reality based mobile platform three-dimensional biomolecule display method. The identification of the traditional paper print biomolecule two-dimensional picture and the three-dimensional real-time display of the corresponding molecule are realized on a mobile platform. The image feature point detection and matching method is improved, so that the display is collaboratively completed by a mobile client and a cloud server, the flexibility is improved, and the client resources are reduced. Three-dimensional molecular modeling data is derived from a PDB (Protein Data Bank), so that the accuracy and the authority are ensured. The augmented reality technology is expanded, a typical application is provided in biochemistry and molecular biology education learning aspects, and the technical means and the framework can be applied to any education and teaching fields; because of the development and popularization of a mobile terminal, and the portable characteristic of the mobile terminal, the system can be used by users at any time and any place, so that the teaching efficiency and the interest in learning are greatly improved.

Description

technical field [0001] The invention is a real-time rendering, interaction and tracking technology of three-dimensional proteins and nucleic acid molecules realized on a mobile platform, and relates to the application of augmented reality technology. Background technique [0002] For a long time, in basic medical science, especially in the teaching and research of subjects like biochemistry and molecular biology, one of the biggest problems is the microscopic nature and invisibility of the research objects. With the advent of the post-genome era and the proteome era, this contradiction is becoming more and more prominent. The rapid development of disciplines requires students and practitioners to master new theories and technologies as soon as possible. The traditional teaching and research methods using paper media as the carrier can no longer keep up with the requirements. [0003] Augmented reality (AR, augmented reality) technology is a technology that uses computer tec...
