Mobile terminal camera calibration parameter writing method and system and mobile terminal

Abstract

The invention provides a mobile terminal camera calibration parameter writing method and system and a mobile terminal. The method specifically comprises following steps: dividing two storage spaces with equal volumes in the memory of the mobile terminal in advance, wherein the storage spaces are used for storing camera calibration parameters, setting a variable X for marking the storage space in which the camera calibration parameters are stored currently; if detecting that the mobile terminal successfully starts a camera, obtaining the value of the current variable X, obtaining a corresponding storage space according to the value of the current variable X, writing the camera calibration parameters stored in the storage space in the camera of the mobile terminal; or if detecting that the mobile terminal is failed to start the camera, storing the value of the current variable X to the memory, and prompting a user that the camera calibration parameters are updated. According to the method, the system and the mobile terminal, the complex process of re-burning the camera calibration parameter by the user is eliminated; the camera parameter debugging efficiency is improved; the camera calibration time of the user is saved; and the convenience is provided to the user.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a method and system for writing camera calibration parameters of a mobile terminal and a mobile terminal. Background technique [0002] At present, the camera performance and image performance of mobile terminals are crucial to the user experience. Therefore, each mobile terminal manufacturer spends a lot of time debugging the camera performance and image performance. The professional term is called camera tuning (camera tuning). ). For camera calibration, the most important thing is to determine a set of camera calibration parameters to achieve the best camera performance and image expression. Determine an optimal set of camera calibration parameters to optimize camera performance and image representation. [0003] In the prior art, the camera calibration parameters are fixed in the mobile terminal software. Every time the camera calibration parameters are cha...

Problems solved by technology

[0003] In the prior art, the camera calibration parameters are fixed in the mobile terminal software. Every time the camera calibration parameters are changed, it is necessary to modify the relevant code, recompile and generate the software, and burn the software to the mobile terminal before observing this group. The effect of camera calibration parameters, so it takes a long time; in addition, when the camera calibration needs to be upgraded, the user also needs to download the entire software from the Internet (or go to the service network) and burn it into the mobile terminal, and the time spent is also Longer, which brings a lot of inconvenience to users
