Problems solved by technology

[0003] At this stage, based on the surround-view calibration method, 360-degree surround-view image stitching can be realized. However, during the actual driving of the terminal, due to changes in the load on the terminal, road conditions, and centrifugal force when turning, the images cannot be stitched well, which will lead to splicing. The completed surrounding environment image has image misalignment, fracture, and large-scale ghosting, which makes the image difficult to identify, reduces the driving experience, and may also cause driving safety hazards

Abstract

The embodiment of the invention discloses an image processing method and a related terminal device, wherein the method may comprise the steps: determining the pose change amount of M cameras on a target terminal, M being an integer greater than 1; according to the pose change amount of the M cameras, updating the camera parameters of the M cameras, each camera parameter comprising a mapping relation between a coordinate system of an image shot by the corresponding camera and a world coordinate system; and on the basis of the updated camera parameters of the M cameras, splicing images shot by the M cameras to obtain a target image of which the visual angle corresponding to the world coordinate system exceeds a preset visual angle threshold. By implementing the embodiment of the invention, the environment image around a terminal can be accurately spliced, and the driving safety of the terminal is ensured.

Description

technical field [0001] The present application relates to the field of terminal technologies, and in particular to an image processing method and a related terminal device. Background technique [0002] With the development of electronic technology, computer technology, sensor technology and new materials, the safety and experience of mobile terminals are more and more valued by everyone. Compared with many other sensors, the camera system can provide users with more intuitive and accurate surrounding environment information during the movement of the terminal through visual information, and can change the original image into a bird's-eye view through the transformation of the viewing angle. Environmental information around the terminal. For example: in the field of intelligent vehicles, the panoramic surround view system installs wide-angle cameras with a large field of view around the car, which can collect 360-degree environmental pictures around the vehicle at the same ...
