Problems solved by technology

When using the information of the pixels at the splicing part of the linear array detector module to correct, because the data of the pixels at the edge of the single crystal silicon linear array detector module is not stable enough and its value change law is not unique with the temperature, it will cause a negative effect on the correction. come with great difficulty

Abstract

The application provides a real-time correction method, device, equipment and medium for line array detector image mosaic, by obtaining the imaging data collected in real time by the line array detector; performing pre-correction processing on the imaging data; The pixel values ​​of the pixel point set to be corrected in each frame of the imaging data are subjected to single-frame fitting correction. This application can well avoid the influence of PD leakage current, electronic circuit noise, temperature change and PD module manufacturing process on the image splicing without increasing other costs such as hardware, and can not only ensure the correction speed well And calibration quality, but also to achieve good application results.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a real-time correction method, device, equipment and medium for image splicing of line array detectors. Background technique [0002] X-ray linear array detectors are commonly used in security inspection, vehicle inspection, food inspection and industrial non-destructive inspection and other fields. The X-ray line array detector imaging system is composed of a data acquisition card and several line array detector modules. A line array detector module is composed of multiple line array detector modules and circuit boards. Multiple line array detector modules The detector module is connected to the data acquisition card through a "daisy chain" interface, and the data acquisition card uploads the data of all linear array detector modules to the PC to form an image. Due to the daisy-chain working method of the line array detector modules and the cutting process at t...
