Title:
CALIBRATION METHODS AND SYSTEMS FOR IMAGING FIELD
Document Type and Number:
WIPO Patent Application WO/2022/218438
Kind Code:
A1
Abstract:
The present disclosure may provide a calibration system and a method for imaging field. The method may include obtaining a calibration model of a target imaging device. The calibration model may include at least one convolutional layer, and the at least one convolutional layer may include at least one candidate convolution kernel. The method may also include determining a target convolution kernel based on the at least one candidate convolution kernel of the calibration model. The method may also include determining calibration information of the target imaging device based on the target convolution kernel. The calibration information may be used to calibrate at least one of a device parameter of the target imaging device or imaging data acquired by the target imaging device.
