Embodiment 1

[0070] figure 1 The flow chart of the image processing method provided by Embodiment 1 of the present invention, such as figure 1 As shown, the image processing method provided by Embodiment 1 of the present invention includes:

[0071] S100: Obtain a strobe image of a vehicle captured by a frame capture unit;

[0072] In step S100, the snapping unit is used to capture a flash image of the window area on the vehicle, wherein the window area referred to in this embodiment includes the windshield, side glass, sunroof and other possible transparent areas of the vehicle. Specifically, the capture unit may collect multiple consecutive frames of strobe images, or may only collect one frame of strobe images. When collecting multiple frames of strobe images, one frame of strobe images can be selected.

[0073] In this embodiment, only one frame of strobe image is collected. It should be noted that the strobe image can also be referred to as a capture frame, which is a frame indepe...

Embodiment 2

[0135] Embodiment 2 of the present invention provides an image processing device, the image processing device includes a snapping unit, an image enhancement processing unit, and a reflection image area removal unit, the snapping unit is used to collect images; the image enhancement processing unit is used to obtain an initial frame of image, And image enhancement processing is performed on the initial image to obtain the first image; the reflection image area removal unit is used to remove the reflection image area in the first image, and output the image of the object captured through the glass, and the reflection image area is the reflection image area on the glass The image area formed by the reflector.

[0136] The image processing device provided by this embodiment can be applied in a variety of scenarios, for example, it can be applied to photographing indoor objects through the glass of a building, and processing the image of the photographed objects; Indoor environment...

Embodiment 3

[0154] The image processing system provided by Embodiment 3 of the present invention includes: a monocular camera, which is used to collect images; a processor connected in communication with the monocular camera, which is used to obtain an initial frame of an image, and perform processing on the initial image Image enhancement processing to obtain the first image; and removing the reflected image area in the first image and outputting the image of the object captured through the glass, where the reflected image area is the image area formed by the reflective object on the glass. Corresponding to the image processing apparatus provided in Embodiment 2, the image processing system provided in this embodiment may also be applied in various scenarios.

[0155] The following describes an image processing system that takes pictures and processes a moving vehicle as an example. Figure 4 A schematic diagram of the application of the image processing system provided in the embodiment...

Abstract

The invention provides an image processing method, an image processing device and an image processing system, and relates to the field of image processing. The image processing method comprises the steps that a frame of image is collected, image enhancement processing is carried out on the image to obtain a first image, the first image comprises a reflection image region and a background image region, the reflection image region comprises an image region formed by a reflection object on glass, and the background image region comprises an image region formed by an object shot through the glass; and the reflection image region is removed to obtain a clear image of the object behind the glass. The invention also provides an image processing device comprising a snapshot unit, an image enhancement processing unit and a reflection image region removal unit, and an image processing system comprising the monocular camera and a processor. According to the invention, by removing the reflection image region in the image, the definition of the object in the image is improved, and the problem that the image shot through the glass is not clear is solved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method, an image processing device and an image processing system. Background technique [0002] When shooting objects through glass, the glass tends to reflect light due to factors such as illumination, resulting in unclear images. When the window is photographed and imaged, the permeability is poor, so that there are more obvious color stripes in the image of the environment inside the car captured by the surveillance, resulting in unclear images of the environment inside the car, and it is difficult to recognize faces in the car. [0003] In related technologies, it is usually necessary to remove the flash spots left by the flashing lamp in the image, the glass reflection image, and the attachment image, etc., so as to obtain a high-quality main image. Generally, it is necessary to collect multiple frames of image information for dereflecti...
