Camera mapping method based on virtual equipment

Abstract

The invention discloses a camera mapping method based on virtual equipment. The method comprises the steps that a virtual camera drive is created according to a Windows system WDM camera drive frame, and a virtual equipment bus drive is created according to a Windows system general drive frame; a camera operation plugin is created on a cloud terminal, and a client side communication module is created; the virtual equipment bus drive obtains physical information of a local camera through the client side communication module and the camera operation plugin, and meanwhile a virtual camera with the same physical information as the local camera is created; the Windows system automatically loads the virtual camera drive to the virtual camera, then the virtual camera can be in communication with Windows DirectShow middleware through the virtual camera drive, and communication between the virtual camera and the Windows application program is achieved. By means of the camera mapping method based on the virtual equipment, a user application program can operate the virtual camera as the local camera.

Description

technical field [0001] The invention specifically relates to a virtual device-based camera mapping method. Background technique [0002] With the development of cloud computing technology, cloud desktop technology is more and more widely used. As a remote desktop technology, cloud desktop technology has many problems in the use of peripherals, such as USB peripherals, serial and parallel port peripherals, etc., which need to be mapped to the server through special mapping technology. Although our commonly used camera is used as a USB device, it cannot be used in a cloud desktop environment by using a common USB mapping technology due to the need to transmit a large amount of image data in practical applications. [0003] For the camera device, the existing solution is based on the Windows DirectShow framework, and the data in the terminal camera is transmitted to the application program in the cloud desktop by developing the DirectShow camera middleware, but the existing te...

AI Technical Summary

Problems solved by technology

[0004] 1. The method relies on the Windows DirectShow framework. The middleware of a camera device implemented under this framework cannot find the actual device in the system.

[0005] 2. The camera middleware implemented using this method always has the same name, which is created when the middleware is created and cannot be modified later

[0006] 3. There are differences between the middleware developed by the third party and the camera DirectShow middleware that comes with the Windows system. User applications are generally developed in the local environment. Using the Microsoft standard DirectShow middleware may have compatibility issues

[0007] 4. Because the old implementation method does not have hardware information in the system, some applications will enumerate the camera device information before using the camera and match their own company's products, resulting in the old camera mapping mode not working well in many environments Use with business systems
