Embodiment Construction

[0035] The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples cited are only used to explain the present invention, not to limit the scope of the present invention.

[0036] As attached image 3 As shown, a multi-camera live broadcast method includes the following steps:

[0037] S1. Fix at least two depth cameras in the live scene, and obtain and store the background depth value of each live scene through the depth cameras;

[0038] The depth camera uses a color / depth camera (RGBD camera) to obtain the depth image in the live scene, and finds the exact location of the current anchor through the skeleton detection technology (open source OpenNI / NiTE technology).

[0039] Due to the lighting of the live broadcast scene and the clothes of the host, the hairstyle and styling change greatly, and the shooting angle of the camera varies greatly on different host platforms. If you use an ordinary RGB camera, thr...

Abstract

The invention discloses a multi-camera live method and system. The method comprises the following steps: S1, fixing at least two depth camera positions in a live scene, acquiring and storing a background depth value of each live scene through each depth camera; S2, acquiring the current position depth image of an anchor through the depth camera, generating an optimal depth camera serial number according to the depth image, and switching the live picture to the camera picture; S3, detecting whether the anchor position is changed through the depth camera, and repeating the step S2 when the anchor position is changed. The system comprises a storage module, a camera group, and a processor; the camera group comprises at least two depth cameras; the storage module is used for storing the background depth value of each live scene; a live scene processor is used for the optimal camera serial number. By use of the method disclosed by the invention, the switching of the optimal camera is automatically realized, and the smoothness of the live process can be maintained in various interaction processes of the network anchor and the audience.

Description

Technical field [0001] The present invention relates to the field of web live broadcast technology, and in particular to a multi-camera live broadcast method and system. Background technique [0002] With the rapid development of high-speed wired and wireless IP networks, large-capacity data storage, digital video compression, and large-scale computing technologies, based on various video sensors, our visual tentacles have been continuously extended to a greater breadth and depth. At the same time, with the continuous development of social networks, people's requirements for the richness of information that can be grabbed are increasing. Therefore, rich media came into being. The demand for live real-time video information is becoming more and more prominent, and live video broadcasting has quickly become the most direct and popular form of rich media. Live broadcast usually refers to a way to synchronously collect, produce, and publish video (usually including audio) informati...
