Embodiment approach 1

[0062] Embodiment 1: performing binarization processing on the target area to obtain a binarized target area;

[0063] extracting a straight line group from the binarized target area by using a preset boundary detection algorithm;

[0064] Mapping the group of straight lines to a preset distance-angle coordinate system by means of Hough transform;

[0065] In the preset distance-angle coordinate system, obtain the target point with the most frequent mapping;

[0066] The first angle value of the target point is used as an inclination angle when the dual camera device shoots the target area.

[0067] Wherein, the preset boundary detection algorithm may be a Canny operator, a Roberts operator, a Sobel, a Prewitt operator, and the like.

Abstract

The invention provides a calibration method and device for an inclination angle of a double-camera device. The method comprises the steps of acquiring to-be-corrected images and determining target areas in the to-be-corrected images; acquiring the inclination angle when the double-camera device photographs the target area; determining a rotation direction of the images according to an aspect ratioof the target area, calculating a rotation angle of the target area according to the inclination angle when the target area is photographed, according to the rotation angle of the target area, rotating the to-be-corrected image corresponding to a left camera in double cameras based on the rotation angle, and rotating the to-be-corrected image corresponding to a right camera in the double camerasbased on the rotation angle. The image photographed according to certain inclination angle is corrected, so the image or a video is adjusted to a position suitable for a watcher to watch. The condition that the vision of the watcher is unconformable due to the problem of the inclination angle when the image is photographed is eliminated, so the user experience is improved.

Description

technical field [0001] The present invention relates to the field of optics, in particular to a method and device for correcting the inclination angle of a dual camera device. Background technique [0002] The dual-camera device refers to a camera device equipped with dual cameras, such as a binocular camera or a mobile phone or an IPAD equipped with dual cameras. A dual-camera device is generally composed of two horizontally parallel cameras, which can image the same scene from different positions, and the duration of the two cameras is the same as the structure of the human eye. The method of distance can realize the perception of three-dimensional information. When people wear VR (full name in English: Virtual Reality, full name in Chinese: virtual reality) glasses or other 3D display devices, they can see the three-dimensional effect of photos or videos recorded by the camera. [0003] However, when shooting an object through a dual-camera device, the dual-camera device...
