Embodiment 1

[0026] According to an embodiment of the present invention, an image correction method is provided, such as figure 1 As shown, the method includes:

[0027] S102: Select a reference object corresponding to any one of the multiple types of light from the multiple reference objects;

[0028] S104: When the reference object corresponding to the any type of light is irradiated with the any type of light, an image of the reference object corresponding to the any type of light is acquired, which is recorded as the first reference image;

[0029] S106: When using any type of light to irradiate the target, an image of the target is acquired and recorded as a target image;

[0030] S108: Correct the target image according to the first reference image, and output the corrected target image.

[0031] It should be clear that one of the problems to be solved by the technical solution of the present invention is to provide a method to realize the correction, or optimization, of the target image, in w...

Embodiment 2

[0067] According to an embodiment of the present invention, there is also provided an image correction device for implementing the above image correction method, such as figure 2 As shown, the device includes:

[0068] 1) The selection unit 202 is configured to select a reference object corresponding to any one of the multiple types of light among multiple reference objects;

[0069] 2) The first acquisition unit 204 is configured to acquire the image of the reference object corresponding to any type of light when the reference object corresponding to the any type of light is irradiated with the light of any type, denoted as the first A reference image;

[0070] 3) The second acquisition unit 206 is configured to acquire an image of the target when any type of light is used to irradiate the target, which is recorded as a target image;

[0071] 4) The correction unit 208 is configured to correct the target image according to the first reference image and output the corrected target i...

Abstract

The invention discloses a method and a device for image correction. The method comprises steps that: one reference object which corresponds to any type of light of multiple types of light is selected from multiple reference objects; when the any type of light is utilized to irradiate the reference object corresponding to the any type of light to acquire an image of the reference object corresponding to the any type of light, and the image is marked as the first reference image; when the any type of light is utilized to irradiate a target object to acquire an image of the target object, and the image of the target object is marked as the target image; the target image is corrected according to the first reference image, and the target image after correction is outputted. Through the method and the device, a technical problem that a single white reference prospectus can not realize accurate correction on the target image under application of multiple types of light is solved.

Description

Technical field [0001] The present invention relates to the field of image processing, and in particular to an image correction method and device. Background technique [0002] In the prior art, the scanner can be used for scanning the paper to be scanned, and the banknote detector can be used for the inspection of the banknote to be inspected. For the two, the components used to obtain the target image can be similar. , Both can use sensors that can recognize visible light, such as silicon photocells. The difference between the two is more reflected in the type of light irradiated to the target. Therefore, a feasible solution to combine the two into one The target image is acquired by the same set of image acquisition equipment, but the light irradiated on the target object can be selected from multiple types of light when acquiring the target image. [0003] In the prior art, there are multifunctional all-in-ones that adopt this solution. When capturing images, different types o...
