Embodiment

[0066] Such as figure 1 , figure 2 and image 3 as shown, figure 1 It is a schematic flowchart of the first method for adaptively performing image true color restoration in this embodiment; figure 2 For the embodiment of the present invention figure 1 A schematic flow chart of the method for adaptively performing image true color restoration; image 3 For the embodiment of the present invention figure 1 A schematic flowchart of the principle of the image restoration processing method for adaptively performing image true color restoration. By finding out the influence of several kinds of ambient light that are common in real life on the true color of objects, and by building a deep learning network to learn this rule, the real color of the object during imaging can be restored in real time according to the learned rule. Providing an adaptive true color reproduction monitoring system will be an effective idea to greatly improve the accuracy and reliability of security. ...

Abstract

The invention provides a method and a system for adaptively restoring the true color of an image. The method comprises the following steps: performing training according to the pixel gray value of a reference object in a training set and the true color information of the reference object to obtain the corresponding relationship between the pixel gray value of an image captured under the conditionof environmental spectral information and the true color information of the image; receiving a current photographed image of the imaging device and current ambient spectral information of a spectral probe balanced with the center of the optical axis of the imaging device; analyzing the current photographed image to obtain the gray value of each pixel of the current photographed image; obtaining apixel gray level compensation value of the current photographed image according to the corresponding relationship between the pixel gray level value of the photographed image under the current environmental information and the true color information of the image; obtaining a restored image of the currently captured image according to the pixel gray compensation value of the currently captured image and the gray value of each pixel of the currently captured image. The invention can quickly and accurately restore the image color.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a method and system for adaptively performing true color restoration of an image. Background technique [0002] Security monitoring is very important for maintaining social stability, enhancing urban public security management, and improving people's sense of security and happiness in life. In various interactive scenarios, the security system can record and store scene events in real time through images, which is convenient for subsequent viewing and restoration of the scene at that time, and provides a large amount of original data and evidence for tracing illegal and criminal acts. [0003] However, most of the current security systems still use traditional imaging equipment, that is, RGB images or videos are generated by fixed optical filters and band response functions. The RGB image or video generated by the traditional imaging system conforms to the ima...
