Embodiment Construction

[0039] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0040] refer to figure 1 , shows a schematic structural diagram of an embodiment of an image enhancement system suitable for traffic control according to the present invention. As shown, including:

[0041] The receiving unit 11 is used to obtain the original image.

[0042] The original image here may be a real-time traffic state image captured by a camera.

[0043] The contrast stretching unit 12 is configured to perform contrast stretching on the obtained original image.

[0044] The purpose of stretching is to make it easier to identify a certain area. For the specific stretching process, please refer to figure 2 Relevant steps in the example shown.

[0045] The image fusion unit 13 is configured to perform image fusion on the contrast stretched image.

[0046] For the specific process of image fusion, please refer to figure 2 Relevant steps for the illu...

Abstract

The invention discloses a method applicable to the traffic control, which comprises the following steps: a. obtaining an original image; b. carrying out contrast grade stretching on the original image; and c. carrying out image merging on the original image and the image after the contract grade stretching; and d, outputting the merged images. In the invention, because of the adoption of the contract stretching and image merging on the candid images, the identification effect of the image is high. The invention discloses an image enhancement system used for the traffic control.

Description

technical field [0001] The invention relates to the field of traffic control, in particular to an image enhancement system and method for traffic control. Background technique [0002] With the process of urbanization in our country, the rapid increase of car ownership and the coordinated development of regional economy, the traffic situation in our country has become a serious problem, especially the traffic jam and traffic safety problems. Intelligent transportation system becomes the preferred solution to solve these problems, such as detection of traffic flow, adaptive control of signals. Among them, various products based on vision technology have become the focus of attention in recent years, and it is also one of the development trends of the future intelligent transportation industry. The key to vision technology is image capture. Although there is an auxiliary effect of additional light sources, there is still a problem, that is, the captured image is blurred, the ...
