Embodiment Construction
[0049] like Figure 1 to Figure 6 Shown, a kind of non-contact data transmission method based on computer vision of the present invention, comprises the following steps:
[0050] Step 1. Encoding and displaying the image sequence, the process is as follows:
[0051] Step 101, generate a standard calibration image sequence and store it in the first computer: First, generate a frame of M rows and N columns of alternate black and white grid image sequences through the first computer 1, the pixels of each black grid and each white grid are all m×m; then, divide the image sequence of black and white grids into n rows and n columns equally into n 2 image areas, select four black grids or four white grids in each of the image areas, and each of the image areas replaces the selected four black grids or four white grids with four colored grids , the colored grid is a standard marker point with 4n 2 The image sequence of the standard marking points is a standard verification image se...

Abstract
The invention discloses a computer vision based non-contact type data transmission method. The computer vision based non-contact type data transmission method comprises the steps of 1, coding and displaying an image sequence, to be specific, 101, generating a standard checking image sequence, 102, building a standard data image sequence, and 103, displaying the image sequence; and 2, decoding the image sequence, to be specific, 201, obtaining an actual checking image sequence, 202, extracting an actual mark point of the actual checking image sequence and calculating a global transformation homographic matrix, 203, extracting a vertex coordinate of each grid of the actual checking image sequence, 204, resolving each grid affine transformation parameter of the actual checking image sequence and determining binary information carried by each grid of the actual checking image sequence, 205, obtaining an actual data image sequence, and 206, decoding the actual data image sequence. As a camera lens is utilized for acquiring computer image information, single-way transmission of computer intranet and extranet information is realized, and efficient communication of computer information between a secret-relating network and a non-secret-involved network can be solved efficiently.
Description
technical field [0001] The invention belongs to the technical field of computer data transmission, in particular to a non-contact data transmission method based on computer vision. Background technique [0002] The definition of non-contact code reading is to encode computer text information into an image according to a defined encoding format, and obtain the image of the image through physical isolation. Shoot computer information coded images, perform corresponding processing on the obtained images, extract the required information from the images obtained by the camera, and then restore them to the original computer text information according to the defined code, so as to realize one-way high-density computer data retention. transmission. The traditional data transmission adopts the following methods: Scheme 1. Manual copying, two independent networks, the internal network has confidential information, the external network is connected to the Internet, and the internal a...
