A method and device for image splicing based on multiple cameras

Abstract

The present invention relates to a multi-camera-based picture splicing method and device, wherein: a main camera and a plurality of sub-cameras are provided, and the main camera and a plurality of sub-cameras are arranged sequentially from the center to both sides based on the user's frontal gaze direction , and make the field of view radially distributed around the user's head; read the motion state of the user's head, and extract the angular velocity of the user's head in the direction of the heading angle; compare the acquired angular velocity in the direction of the heading angle with the preset threshold , when the angular velocity in the direction of the heading angle is less than the threshold value, the screen of the main camera is displayed directly, and when the angular speed in the direction of the heading angle direction is greater than the threshold value, according to the heading angle displacement of the user's head, the picture is cut out from the screen of the secondary camera and the corresponding screen is selected. , and scaled and displayed after calculating the field of view of the human eye. The multi-camera-based image splicing method and device according to the present invention can solve the problem that the user is easily dizzy due to the slow update speed of the main field of view in the fast turning state.

Description

technical field [0001] The invention relates to the field of optoelectronic information, in particular to a method and device for splicing images based on multiple cameras. Background technique [0002] A vision aid is a device or device used to improve the visual ability of people with low vision, so that the limited vision of people with low vision can be used to the maximum extent. As a kind of vision aids, electronic vision aids can realize diversified functions and excellent performance by being equipped with different electronic devices, and occupy an important position in the vision aid family. Electronic vision aids can generally be divided into handheld, desktop, and head-mounted in terms of usage methods. Among them, head-mounted electronic vision aids have broad development prospects because they allow users to use them in a mobile state and conform to natural eye habits. . Nevertheless, in the case of wearing a conventional head-mounted electronic vision aid, w...
