Problems solved by technology

The image quality collected in clear weather is very good, which can meet the pre-designed standard; but in severe weather conditions such as fog and haze, the quality of the image is seriously degraded, and even the target in the image is blurred and difficult to identify
This situation seriously affects the stability of the image acquisition system, and the image degraded by weather interference will also affect the normal work of other systems

Embodiment Construction

[0019] The structural scheme and working process of the present invention are further illustrated in conjunction with examples.

[0020] Such as figure 1 As shown, the anti-weather interference image acquisition system includes a camera 1, an analog-to-digital converter 2, an image acquisition device 3, a data interface 4, a computer 5, a time weight module 6, a parameter input module 7, a filter module 8, and an image memory 9 and image display 10 . The camera 1 sends the captured image signal to the analog-to-digital converter 2, and the analog-to-digital converter 2 converts the analog image into a digital image, and after being collected by the image collector 3, it is input into the computer 5 through the data interface 4, and the parameter input module 7 converts the time The parameters, meteorological parameters and other parameters are input into the computer, and the time weight module 6 uses the time parameters to calculate the time weight, and the refractive index ...

Abstract

This invention relates to an anti-weather interference image collection system, in which, an AD converter converts the picked up image signals to digital image signals to be input to a computer via a communication interface, a time weight module gets time weight by time parameters and a parameter input module transmits the parameter information to a computer to transfer the modulated transferred function signals of the image to a signal filter module to filer the original image to get a recovered image of the weather. The work flow is: 1, initialization, 2,image collection, 3, image pre-process, 4, time weight computation, 5, computation of index of refraction structure constant, 6, computing the atmosphere modulated transferred function, 7, image filter, 8, storing the image 9, displaying the image.

Description

technical field [0001] The invention belongs to the field of weather image processing, in particular to a method for restoring an attenuated image disturbed by weather. Background technique [0002] In today's world, human vision is far from being able to meet the needs in the industrial field and other fields of human life. The emergence of computer vision systems has made up for the lack of human vision. Computer vision has been widely used in many fields such as industrial manufacturing, road traffic management, and real-time monitoring. It plays an increasingly important role in human production and life. . As an important part of computer vision, image acquisition technology has been widely developed in various fields, especially in fields that require real-time monitoring of observation targets and information storage (for example: road traffic management). In the process of collecting outdoor images by ordinary image acquisition systems, the image quality is serious...
