Example Embodiment

[0092] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, but not to limit the present invention.

[0093] Usually, a visible image is a plane energy distribution map, which can be a radiation source of a luminous object itself, or the energy reflected or transmitted by the object after being irradiated by a light radiation source.

[0094] Digital images can be represented by two-dimensional discrete functions:

[0095] I=f(x, y)

[0096] Among them, (x, y) represents the coordinates of the image pixel, and the function value f(x, y) represents the gray value of the pixel at the coordinates.

[0097] It can also be represented by a two-dimensional matrix:

[0098] I=A(M, N)

[0099] Among them, A is the matrix representation, and M and N are the matrix row and column lengt...

Abstract

The invention discloses a vehicle infrared image compression and enhancement method and system, and the method comprises the steps: intercepting infrared image data from a video stream collected by a vehicle, converting the hexadecimal image data into the position information and the pixel value of each pixel point according to a transmission protocol, and forming an infrared bitmap image in a BMP format; compressing the infrared bitmap image to a size suitable for transmission to obtain a compressed image, and storing the compressed image in a memory for backup; and converting the compressed image into a 8-bit byte code according to the base64 code. The infrared imaging and image compression and enhancement principle is utilized to solve the problems of low precision and low speed of a visual sensor and large image occupation space in the Internet of Vehicles.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and system for compressing and enhancing an infrared image of a vehicle. Background technique [0002] The research on image compression coding can be traced back to the digitization of television signals in 1984. Until now, the longest and most widely used image compression technology is the JPEG (Joint Photographic Experts Group) compression standard formally established in 1992, whose official name is "Digital Compression Coding for Continuous-tone Still Images in Information Technology". It adopts the joint coding method of predictive coding, discrete cosine transform and entropy coding, and achieves a higher compression ratio with lower algorithm complexity, and the compressed image also has good reconstruction quality. But when the compression ratio is too high, the image quality is easily damaged, so JPEG is not suitable for displaying high-definition im...
