Abstract

The embodiment of the invention provides a dual-camera calibration method, a device, a system and a mobile terminal; the method comprises the following steps: sending a control order to a robot arm soas to drive the robot arm to carry a calibration board to rotate for many angles, wherein the calibration board has a calibration pattern; invoking the dual-camera to gather multi-image data pieces of the calibration board under many angles; measuring a plurality of position information pieces of the calibration pattern in the plurality of image data pieces according to the color distribution information; calibrating the inner and outer parameters of the dual-camera according to the plurality of position information pieces. The calibration board employs a two-dimensional plate, is low in technical precision, and simple to make; the system formed by the calibration board and the robot arm is simple to operate, low in cost, and suitable for applications on industrial streamlines.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a dual-camera calibration method, a dual-camera calibration device, a dual-camera calibration system and a mobile terminal. Background technique [0002] With the development of mobile communication technology, mobile terminals such as mobile phones and smart wearable devices are becoming more and more popular, bringing great convenience to people's life, study and work. [0003] Mobile terminals are usually equipped with a camera to complete functions such as large aperture, dark light enhancement, object size measurement, and three-dimensional imaging that simulate a single-lens reflex digital camera. [0004] However, when the relative positions of the dual cameras are fixed, the optical axes of the two cameras are not parallel due to positional errors, resulting in vertical ( The offset in the horizontal) direction leads to the deterioration of the effects of t...
