This application provides an image processing method, including: performing stabilization on two adjacent image frames of a video stream acquired by a camera to obtain cropped areas, and performing perspective distortion correction on the cropped areas obtained through stabilization. Because the cropped areas output after stabilization is performed on the two adjacent frames include same or basically same content, it can be ensured that a subsequently generated video is smooth and stable. In this application, position relationships, for perspective distortion correction, between the cropped areas obtained through stabilization are further mapped, so that degrees or effects of perspective distortion correction of the adjacent frames of the subsequently generated video are the same, in other words, degrees of transformation of a same object in the images are the same.

Image processing method and related device

An image transformation method includes obtaining a first image for a target scenario by using a front-facing camera, where the target scenario includes a face of a target person; obtaining a target distance between the face of the target person and the front-facing camera; and when the target distance is less than a preset threshold, performing first processing on the first image to obtain a second image. The first processing includes performing distortion correction on the first image based on the target distance. The face of the target person in the second image is closer to a real appearance of the face of the target person than the face of the target person in the first image.

An optical path switching method is applied to a surveillance module. The method includes: determining a target magnification; and (i) when the target magnification is less than or equal to a maximum magnification of a camera, setting a magnification of the camera to the target magnification, determining that a reflection element is at a first location or in a first working state, and performing image capture by using the camera alone; or (ii) when the target magnification is greater than a maximum magnification of the camera, setting a magnification of the camera to a first magnification, determining that the reflection element is at a second location or in a second working state, and performing image capture by using both the camera and a teleconverter, where a product of the first magnification and a magnification of the teleconverter is the target magnification. The method increases a surveillance distance while reducing costs.

Optical path switching method and surveillance module

A method can measure the size of an object using a terminal having two cameras. The method includes obtaining, by a terminal using a first camera, a first image that includes a to-be-measured object, and obtaining, using a second camera, a second image that includes the to-be-measured object, where the first camera and the second camera are disposed in a same plane. The method also includes comparing locations of the to-be-measured object in the first image and in the second image, so as to obtain a total location offset of the to-be-measured object. Additionally, the method includes receiving a measurement point selection instruction entered by a user based on the first image, and calculating a distance between selected measurement points according to the total location offset, a distance between a center of the first camera and a center of the second camera, and a focal length of the first camera.
