Problems solved by technology

[0003] At present, in the desktop cloud computing infrastructure, the USB mapping method can be used to solve the problem of using the local camera, but this implementation has the following disadvantages: 1. Due to the large amount of camera data, the USB mapping method is used as a general USB The device mapping method cannot be specially optimized for devices such as cameras
2. Due to the high demand for bandwidth, in the actual use process, there are often phenomena such as screen flickering and frame dropping, which affect the use effect

Embodiment Construction

[0018] In the desktop cloud computing infrastructure, the local cloud terminal captures the running view of the virtual desktop running in the data center to the local display through the remote desktop connection protocol client, making the user feel like using the remote virtual desktop. Access the same as a traditional locally installed desktop. Since the real system environment runs on the server in the data center, the physical connection is separated, so the remote virtual desktop cannot directly use the local camera of the cloud terminal. When the camera is used in the desktop cloud environment, there are mainly two data streams, one is the camera image data stream uploaded locally to the server, and the other is the local video image data stream for human-computer interaction. The present invention is based on the characteristics of the Microsoft DirectShow framework, improves and expands it, builds a virtual camera Source in the virtual desktop, then establishes a con...

Abstract

The invention relates to a method for seamlessly using a cloud terminal local camera in a VDI (Virtual Device Interface) virtual desktop. An original DirectShow technical framework is improved, a virtual camera and a virtual player are constructed, the virtual camera transmits a data request to a redirection client through a redirection server, the redirection client operates terminal local real camera equipment to obtain image data of a frame, then the image data are compressed through a streaming media compression algorithm and then is transmitted back to the virtual camera and the image data are decompressed by the virtual camera and transmitted to the virtual player through a DirectShow framework; at the same time, the redirection client directly displays images at a screen coordinate position provided by the virtual player to complete the echoing of camera data. The method for seamlessly using the cloud terminal local camera in the VDI virtual desktop enables a user to log in the virtual desktop to seamlessly use the cloud terminal local camera and solves the problem that the echo data of the camera occupy network bandwidth when the camera is used.

Description

【Technical field】 [0001] The invention belongs to the technical field of computer software, and specifically refers to a method for seamlessly using a local camera of a cloud terminal in a VDI virtual desktop. 【Background technique】 [0002] The VDI virtual desktop infrastructure concentrates computing resources and storage resources in the data center, but there is no perfect solution for user-side operating resources (input and output devices such as various peripherals). [0003] At present, in the desktop cloud computing infrastructure, the USB mapping method can be used to solve the problem of using the local camera, but this implementation has the following disadvantages: 1. Due to the large amount of camera data, the USB mapping method is used as a general USB The device mapping method cannot be specially optimized for devices such as cameras. 2. Due to the high demand for bandwidth, in the actual use process, there are often phenomena such as screen flickering and f...
