Embodiment Construction

[0020] First, terms involved in the embodiments of the present application are described.

[0021] Field of View (FOV): Also known as the angle of view, in optical instruments, the angle formed by the lens of the optical instrument as the vertex and the two edges of the maximum range of the object image that can pass through the lens is called the field of view horn. In a display system, the field of view is the angle between the edge of the display and the line connecting the viewing point (eye).

[0022] Attitude angle: also known as Euler angle, attitude angle / Euler angle is more commonly used in the aerospace field to indicate the attitude of the body relative to the ground. Such as Figure 4 As shown, the attitude angle includes pitch angle, roll angle and yaw angle. The pitch angle is the rotation angle of the body relative to the Y axis, the roll angle is the rotation angle of the body relative to the X axis, and the yaw angle is the rotation angle of the body relativ...

Abstract

The application provides an intelligent live broadcast method, a wearable device and an intelligent live broadcast system, which relate to the field of virtual reality technology, and can intelligently display the target image selected by the user in the live broadcast without the user needing to actively search for the target object, saving the user's time , so that users can get a better live viewing experience. The method is applied to a wearable device, and includes: receiving a target panoramic video and first coordinate information, the target panoramic video contains a target image, and the first coordinate information is used to indicate the position of the target image in the target panoramic video First position; acquire second coordinate information, the second coordinate information is used to indicate the posture of the wearable device; based on the first coordinate information and the second coordinate information, the wearable device displays the A target frame of the target panoramic video, where the target frame includes the target image.

Description

technical field [0001] The present application relates to the field of virtual reality technology, and in particular to an intelligent live broadcast method, a wearable device and an intelligent live broadcast system. Background technique [0002] In a live video solution using virtual reality (virtual reality, VR) technology as a carrier, generally multiple 360° panoramic camera devices are deployed to collect panoramic video. When the position of the target object changes so that the target object moves from the collection range of one panoramic camera device to the collection range of another panoramic camera device, using image recognition technology, the VR device can automatically switch to display the panoramic video including the target object. [0003] However, since the viewing angle of the user of the VR device is 360°, and the field of view (field of view, FOV) of the VR device is usually set to 120°, after the VR device is switched to display a panoramic video i...
