Document Type and Number:
WIPO Patent Application WO/2023/185674
Kind Code:
A1
Abstract:
Disclosed in the embodiments of the present application are a calibration method, a calibration system, a photographing method, an electronic device and a storage medium, which are used for realizing the calibration of a gradually variable iris diaphragm. The calibration method comprises: acquiring a first clear aperture of a diaphragm stop to be calibrated; determining a target location of a diaphragm motor corresponding to the first clear aperture; after a rotor of the diaphragm motor is driven to move to the target location, acquiring an image to be processed which comprises an iris diaphragm light through hole; determining a second clear aperture of the light through hole according to the image to be processed: if an error requirement is not met, determining the next target location of the diaphragm motor according to a first correlation and the second clear aperture, and then returning to the step of acquiring an image to be processed and determining a second clear aperture according to the image to be processed; if the error requirement is met, determining the target location as a motor calibration location of the diaphragm stop to be calibrated; and according to the motor calibration location of each diaphragm stop to be calibrated, obtaining the relationship between the diaphragm stop and the location of the aperture motor.
