Abstract

The invention discloses a correction parameter determining method, device and equipment, applied to automatic exposure control AEC correction. The method comprises the following steps: acquiring a theoretical correction parameter of a target system, wherein the theoretical correction parameter is a corresponding independent variable value when a dependent variable in a linear fitting function of the target system is a preset target dependent variable parameter, and the linear fitting function is a fitting function that the preset dependent variable parameter is in linear change along with a preset correction parameter; acquiring a first dependent variable parameter of the target system, wherein the first dependent variable parameter is obtained by carrying out AEC correction according to the theoretical correction parameter; and determining the theoretical correction parameter as a target correction parameter which is matched with the target dependent variable parameter when an error between the first dependent variable parameter and the target dependent variable parameter is within a preset error range. According to the embodiment disclosed by the invention, correction times are effectively reduced and the target correction parameter, which is matched with the target dependent variable parameter, is rapidly acquired, so that the correction parameter determining efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of parameter calibration, and in particular to a calibration parameter determination method, device and equipment. Background technique [0002] Digital Radiography (DR, Digital Radiography) equipment is widely used because of its low radiation dose, high image quality, high disease detection rate and diagnostic accuracy. The automatic exposure control (AEC, Automatic Exposure Control) correction of the DR system is very important during the use of the DR system. [0003] AEC calibration requires that the corresponding parameters after exposure are within the preset range. To perform AEC calibration on the DR system, it is usually necessary to repeatedly set the parameters to be corrected, perform exposure for each set of parameters to be corrected, and judge whether the corresponding parameters after exposure are within the preset range. scope. [0004] The above-mentioned AEC correction method ...
