Embodiment Construction

[0011] Refer to attached figure 1 The present invention provides an image noise reduction processing system of an X-ray inspection apparatus, which is characterized in that the system includes an image storage unit, an image processing unit, and an image display control unit.

[0012] When the image data information collected by the X-ray inspection instrument passes through the X-ray image data memory, the image data is buffered and stored, and then the data is transmitted to the central processing unit, and the central processing unit sends a signal to the program memory of the image processing unit to call its program The algorithm performs histogram equalization and multi-frame average filtering algorithm processing on the image data, and the processed clear image is then transmitted to the image display unit through the central processing unit, and the image display unit presents high-quality, clear images to people.

[0013] The histogram equalization algorithm is charac...

Abstract

The invention relates to an image denoising processing system of an X-ray inspection instrument. The image denoising processing system of the X-ray inspection instrument comprises an image storage unit, an image processing unit and an image display control unit. The image storage unit adopts a high-definition image storage mode and saves images in a BMP format. The image processing unit mainly comprises histogram equalization and noise reduction by using a multiframe average filtering algorithm, the module of the image processing unit adopts an embedded control system and can read data signals of an image memory at any time, the noise signals in X-ray images can be effectively reduced through the programmed algorithm of the image processing unit, and image quality can be improved. The image display control unit carries out an encoding process and an electrical level transformation process on output parallel signals through an internal programmable array design, and enables the data signals to be capable of being displayed as clear images through a display part. The image denoising processing system of the X-ray inspection instrument is widely involved in application, and improves the image quality.

Description

technical field [0001] The invention relates to the technical field of X-ray image processing, in particular to an image noise reduction processing system of an X-ray inspection instrument. Background technique [0002] X-ray imaging detection technology is an important non-destructive testing method in the current high-tech society, and has been widely used in medicine, industry, security inspection, national defense and other fields. However, because of the introduction of CCD and other devices in the portable X-ray inspection instrument, there are some problems that cannot be ignored. In the process of digital imaging system, due to various reasons, noise must be introduced, which will cause the decline of image quality and greatly affect the quality of doctors. diagnostic accuracy. Therefore, the present invention provides an image noise reduction processing method for a portable X-ray inspection instrument, which can effectively process various noises existing in image...
