Embodiment Construction

[0064] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0065] Such as figure 1 Shown is a functional block diagram of an image defogging device based on an unmanned vehicle provided by the present invention, including an image acquisition device, an ambient light estimation module, an atmospheric light curtain estimation module, an image restoration module, and an image adjustment module.

[0066] The image acquisition device can use a camera, which is installed on the windshield of the driverless car, collects the surrounding environment images of the car in time and transmits them to the ambient light estimation module and the atmospheric light curtain estimation module respectively.

[0067] The ambient light estimation module partitions the env...

Abstract

The invention discloses an image defogging device based on a pilotless automobile. The image defogging device comprises an image collecting device, an ambient light estimating module, an atmosphere light curtain estimating module, an image restoring module and an image adjusting module, wherein the image restoring module is used for calculating a restoring image according to the ambient light, an atmosphere light curtain and an atmosphere scattering model, and the image adjusting module comprises a brightness adjusting module and a tone adjusting module and is used for adjusting the brightness and the tone of the restored image. The invention further discloses an image defogging device based on the pilotless automobile. The method comprises the steps of carrying out ambient light estimation and atmosphere light curtain estimation on the ambient image; calculating a restoration image; carrying out brightness and tone adjustment on the restored image according to the visual characteristics of the human eyes. By means of the image defogging device and method based on the pilotless automobile, a three-dimensional visual system of the pilotless automobile can be improved, firstly, defogging processing is carried out on a front road image, then a real-time 3D image is synthesized, the definition and the accuracy rate of the 3D image can be increased, and potential danger can be found in time earlier.

Description

technical field [0001] The invention relates to an image defogging device and a defogging method, in particular to an image defogging device and a defogging method based on an unmanned vehicle, and belongs to the technical field of image processing. Background technique [0002] The high level of intelligence of unmanned vehicles lies in the large number of powerful sensors, among which there is a stereo vision system, whose main function is to form a real-time 3D image from the images taken by the camera installed on the windshield , find potential hazards, such as: pedestrians, bicycles and predict their direction. However, many experiments do not consider the impact of harsh environments, such as this year's severe smog weather. In this environment, objects on the road are likely to be blocked by smog, which will affect the synthesis of real-time 3D images, and thus affect the potential hazards. judgment. In view of the above scenario, the influence of haze on the image...
