X-ray chest radiography image quality determination method and device

The invention relates to an X-ray chest radiography image quality determination method. The invention further relates to an X-ray chest radiography image quality determination device. The method comprises the following steps: carrying out normalization processing on an X-ray chest radiography image; inputting the normalized image into a deep learning model for image separation and recognition to obtain at least one separation result, wherein the deep learning model at least comprises one of the following formulas: a lung lobe segmentation model, a spine segmentation model, a scapula segmentation model and a foreign matter detection model; and determining the image quality of the X-ray chest radiograph based on the separation result. According to the invention, the X-ray chest radiography image quality is fully automatically evaluated, and the image quality determination speed is high; and a technician can be helped to control the image quality of the chest radiograph, so that the radiograph reading accuracy i
