A method and system for self-adaptive image true color restoration

Abstract

The present application provides a method and system for self-adaptive image true color restoration, the method includes: training according to the pixel gray value of the reference object in the training set and the true color information of the reference object to obtain the image captured under the condition of environmental spectral information The corresponding relationship between the pixel gray value and the image true color information; receive the current captured image of the imaging device and the current environmental spectral information of the spectral probe balanced with the optical axis center of the imaging device; analyze the current captured image to obtain the gray level of each pixel of the current captured image value; according to the corresponding relationship between the pixel gray value of the captured image under the current environment information and the true color information of the image, the pixel gray compensation value of the current captured image is obtained; according to the pixel gray compensation value of the currently captured image and the value of each pixel of the current captured image The grayscale value is the restored image of the currently captured image. The invention can quickly and accurately restore 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...
