Scene depth calculation method, device and terminal

Abstract

Embodiments of the present invention relate to a scene depth calculation method, a device and a terminal. The method comprises: obtaining a camera offset of a camera having an OIS system, wherein a first camera and / or a second camera have the OIS system; converting the camera offset into an image offset according to a preset OIS motor sensitivity calibration parameter; calculating the scene depth of a target scene according to a compensated calibration parameter of the first camera and / or a compensated calibration parameter of the second camera, as well as a first image and a second image obtained by the first camera and the second camera photographing the target scene at the same time; wherein the calibration parameter of the first camera is compensated according to the camera offset of the first camera, and the calibration parameter of the second camera is compensated according to the camera offset of the second camera. Therefore, the parallax problem is solved, and the scene depth of a target scene is more accurate as being calculated using the compensated calibration parameters of cameras.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 201610941102.2 and the title of the invention "A Method and Terminal for Image Depth Calculation with Dual Camera Terminal" submitted to the Patent Office of the State Intellectual Property Office of China on October 25, 2016 , the entire contents of which are incorporated in this application by reference. technical field [0002] Embodiments of the present invention relate to the communication field, and in particular to a scene depth calculation method, device and terminal of a target scene with a dual-camera terminal device. Background technique [0003] Currently, the method of implementing depth calculation through dual cameras is being applied to more and more mobile phones, such as the Huawei P9 mobile phone. Optical Image Stabilization (OIS, also commonly referred to as Optical Image Stabilization), as an important means to improve the quality of taking pictures ...

AI Technical Summary

Problems solved by technology

[0005] The embodiment of the present invention provides a scene depth calculation method. When the OIS system exists in one or two cameras, it solves the problem of parallax (positive and negative parallax exist at the same time, or the image cannot be aligned in one direction). Problem with inaccurate depth values
