Problems solved by technology

But in fact, as far as the focal length is concerned, each camera device has a certain error during assembly, and its actual focal length is also different from the theoretical reference value given by the lens manufacturer; as for the optical axis, the two camera devices assembled in When they are together, the optical axes will also produce errors instead of being absolutely parallel, resulting in incomplete observation directions of the two cameras, which will lead to poor user experience when switching cameras

Abstract

The invention provides an image processing method and device, electronic equipment and a computer readable medium, and relates to the technical field of image processing. The method comprises the steps: obtaining a first image collected by a first camera device; determining a target ROI region in the first image; calculating the ROI offset of the target ROI in the first image and the second image;acquiring a current magnification of the first image, and slicing the ROI offset according to the current magnification to obtain a current superposition offset for performing image stereo correctionon the first image at the current moment; performing image three-dimensional correction on the first image based on the current superposition offset to obtain a corrected first image; if the currentmagnification is the preset switching magnification, switching the mobile terminal from the first camera device to the second camera device for display,. The technical problem that in the prior art, when imaging switching of the camera devices is conducted, hopping is obvious is solved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method, device, electronic equipment and computer readable medium. Background technique [0002] For a mobile terminal, its camera device is usually a fixed-focus lens, which can only achieve digital zoom. As consumers have higher and higher requirements for functions such as shooting and video recording, in order to solve the defects of digital zoom at high zoom ratios, more and more mobile terminals are equipped with two or more cameras with different focal lengths. The camera devices are matched, for example, one lens FOV (field angle, field angle)=80°, and one lens FOV=40°. At this time, digital zoom and optical zoom can be combined to satisfy consumers. The combination of digital zoom and optical zoom means that one camera device is used to enlarge the image and then switch to another camera device for imaging. The above method is also ...
