Problems solved by technology

When users use the above-mentioned image acquisition devices, they must be equipped with drivers that meet the interface standards of image acquisition devices in order to work normally. Generally, device drivers are specially configured for image acquisition devices, and they have fast connection and data communication. The advantage of accurate transmission, but this driver can only drive this type of image acquisition device. When using multiple image acquisition devices with different types, models, brands and interface methods, it is necessary to configure multiple corresponding drivers. program, which brings troubles to users

Embodiment 1

[0019] Embodiment 1: The image acquisition hardware device of the present invention is a scanner named KODAK i4600, which supports the TWAIN interface protocol, and the name of the virtual encapsulation layer corresponding to the hardware device is SV_KODAK4600.

[0020] refer to figure 1 , the image collection method based on virtual hardware device of the present invention, comprises the following steps:

[0021] Encapsulate Kofax interface protocol, TWAIN interface protocol, Folder interface protocol, interface protocol based on DirectShow technology, ISIS interface protocol and API interface protocol in the interface protocol encapsulation module; provide the application program with the interface protocol information encapsulated by the interface protocol encapsulation module Call functions corresponding to each interface protocol;

[0022] Load image acquisition hardware equipment, and carry out the detection of virtual hardware encapsulation layer; The detection of des...

Embodiment 2

[0031]Embodiment 2: The image acquisition hardware device of the present invention is a scanner named BANTEC S-185, which does not support the TWAIN interface protocol and belongs to a non-standard protocol interface. The name of the virtual encapsulation layer corresponding to the hardware device is SV_BANTEC. BANTEC series scanners can scan through the ISIS interface protocol. In order to illustrate the non-standard method, this embodiment adopts the interface encapsulation provided by directly calling the device API interface driver. The process of driving the scanner BANTEC S-185 through the virtual encapsulation layer is similar to that through the TWAIN protocol, except that the interface provided by the virtual encapsulation layer is different.

[0032] refer to figure 1 , the image collection method based on virtual hardware device of the present invention, comprises the following steps:

[0033] Encapsulate Kofax interface protocol, TWAIN interface protocol, Folder i...

Abstract

The invention relates to an image collection method based on virtual hardware equipment, which comprises the following steps of: creating an interface protocol encapsulating module; loading image collection hardware equipment; configuring the attributes of the image collection hardware equipment; using program for driving the image collection hardware equipment through invoking the interface protocol in the interface protocol encapsulating module through invoking functions; and carrying out scanning actions. The method of the invention has the advantages that the hardware interface differences of the bottom layer are shielded in the image collection process, a unified processing mode and interfaces are provided for users, various kinds of collection equipment in different types, different brands and different models are managed in a unified way, the dynamic switching between various kinds of collection equipment is realized in the application, in addition, the virtual hardware encapsulating layer memory function is realized, and the independence between the collection hardware equipment and the software is really realized.

Description

technical field [0001] The invention relates to the technical field of image communication, in particular to an image acquisition method based on virtual hardware equipment. Background technique [0002] Image acquisition is an image acquisition process of obtaining image data through image recording equipment under the control of the image business application system. Commonly used image acquisition devices generally include scanners, cameras, and digital cameras. Such image acquisition devices generally have different types, models, and brands, and use different interface methods. The internationally common image acquisition standard interface technologies mainly include TWAIN interface technology, KOFAX interface technology, ISIS interface technology and DirectShow technology. TWAIN interface technology is used to extract images from static image devices. Most scanners and digital cameras provide TWAIN drivers. Using a unified TWAIN interface, applications can easily obt...
