Problems solved by technology

[0002] At present, when shooting outdoor scenes, the camera effect is seriously affected by weather conditions
When the weather is good, the shooting effect is relatively clear, but in bad weather conditions (such as: haze, fog and other weather conditions) the shooting effect is relatively blurred, and serious distortion and information loss will occur in severe cases
Weather conditions have a significant impact on the images captured by the camera system, seriously affecting the performance and stability of the camera system

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, an anti-fog interference camera system includes a camera 1, an analog-to-digital converter 2, an image collector 3, a data interface 4, a threshold judgment device 5, a computer 6, a defogging processing module 7, an image enhancement module 8 and an image monitor9. 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 signal into a digital image signal, which is collected by the image collector 3 and sent to the threshold value judger 5 through the data interface 4, and the threshold value judger 5 Use the contrast to judge the degree of attenuation of the image. If the weather conditions are bad, the attenuated contrast signal of the image is sent to the computer 6 to calculate the scattering model parameters, and then se...

Abstract

This invention relates to a camera system for anti-fog disturbances including transmitting image signals collected by a camera to an AD converter, transmitting digital image signals to a threshold judger via a data interface collected by an image collector, which judges the clearness of the image and transmits the image contrast signal to a computer, if the image is degenerated due to the fog, then a fog-removing module processes it to get the recovered one, the signal of which is transmitted to an image strengthening module to process it. The work flow is: 1, initialization, 2, image collection, 3, image pre-process, 4, threshold judgment, 5, computing of scattered model parameters, 6, fog-removing, 7, image-strengthening 8, if ití»s over the threshold, 9 image display.

Description

technical field [0001] The invention belongs to the outdoor camera technology, in particular to an anti-fog interference camera system and a method for restoring images attenuated by fog. Background technique [0002] At present, when shooting outdoor scenes, the camera effect is seriously affected by weather conditions. When the weather is good, the shooting effect is relatively clear, but in bad weather conditions (such as: haze, fog and other weather conditions) the shooting effect is relatively blurred, and serious distortion and information loss will occur in severe cases. Weather conditions have a significant impact on the images captured by the camera system, seriously affecting the performance and stability of the camera system. Aiming at this problem encountered by the outdoor camera system, it is necessary to design a camera system with anti-fog interference. The camera system should effectively suppress the influence of weather conditions on camera effects when ...
