Abstract
A kind of high-definition image collecting device reorientation method in virtual desktop environment, solve how to realize the operation to high photographing instrument by TWAIN dynamic bases, how by network by picture transfer the problem of, in former scheme, high photographing instrument is to be redirected to by desktop connection protocol in virtual desktop, due to the limitation of network bandwidth, the redirection of usb equipment has certain delay, if high photographing instrument obtains view data with higher resolution ratio, the delay of device redirection can cause high photographing instrument equipment can not use at all.The scheme of patent document realizes the remote control of high photographing instrument equipment, distally takes pictures, and picture is then forwarded into virtual desktop after having clapped.
Description
Technical field
The present invention relates to a kind of desktop virtualization, and in particular to the high-definition image collecting device in a kind of virtual desktop environment
Reorientation method.
Background technology
In production environment, some client needs the electronic photo of captured identity card, certificate, papery certificate etc., high
Clap instrument and aim at such Scenario Design, the object for needing to shoot need to be only put on pallet by client, in the application point
Hit crawl button and be obtained with photo.But in the application scenarios of virtual desktop, if high photographing instrument redirected by usb
Mode be transparent in virtual machine, then by the client software capturing pictures in virtual machine, because network delay is led
Cause capturing pictures failure.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, it is an object of the invention to provide the high definition in a kind of virtual desktop environment
How image capture device reorientation method, solution are realized the operation to high photographing instrument by TWAIN dynamic bases, how to pass through network
The problem of by picture transfer.
To achieve these goals, the technical solution adopted by the present invention is：
High-definition image collecting device reorientation method in a kind of virtual desktop environment, it is characterised in that comprise the following steps：
1）High photographing instrument serve end program is realized in FTP client FTP, for including the high photographing instrument of all connections on the client
Equipment, and device name list is stored in local memory data, when high photographing instrument client is initiated to ask, by list of devices
It is sent to high photographing instrument client；
2）High photographing instrument client-side program is realized in virtual desktop system, for connecting high photographing instrument serve end program.When successfully connecting
After being connected to serve end program, the list of devices that service end is sent can be received, and list of devices is inserted into list of devices and got off dish
Dan Zhong；
3）When high photographing instrument client selects some high photographing instrument equipment, and after clicking on button of taking pictures, high photographing instrument client is by equipment
Title and photographing command are sent to high photographing instrument serve end program, and high photographing instrument serve end program is carried by windows systems
TWAIN protocol dynamic libraries, high photographing instrument is operated, take pictures and picture is stored in the catalogue that client specifies；
4）After high photographing instrument service end grabs picture, picture is sent to by high photographing instrument client by socket.
The beneficial effects of the invention are as follows：
In former scheme, high photographing instrument is to be redirected to by desktop connection protocol in virtual desktop, due to Netowrk tape
Wide limitation, the redirection of usb equipment have certain delay, when high photographing instrument obtains view data with higher resolution ratio
Words, the delay of device redirection can cause high photographing instrument equipment can not use at all.The scheme of patent document realizes high photographing instrument
The remote control of equipment, is distally taken pictures, and picture is then forwarded into virtual desktop after having clapped.
Brief description of the drawings
Fig. 1 is this principle flow chart of the invention.
Fig. 2 is the implementation photo of the present invention.
Fig. 3 is the implementation photo of the present invention.
Fig. 4 is the implementation photo of the present invention.
Embodiment
The present invention is further discussed below below in conjunction with accompanying drawing.
As shown in Figure 1,2,3, 4, the high-definition image collecting device reorientation method in a kind of virtual desktop environment, its feature
It is, comprises the following steps：
1）High photographing instrument serve end program is realized in FTP client FTP, for including the high photographing instrument of all connections on the client
Equipment, and device name list is stored in local memory data, when high photographing instrument client is initiated to ask, by list of devices
It is sent to high photographing instrument client；
2）High photographing instrument client-side program is realized in virtual desktop system, for connecting high photographing instrument serve end program.When successfully connecting
After being connected to serve end program, the list of devices that service end is sent can be received, and list of devices is inserted into list of devices and got off dish
Dan Zhong；
3）When high photographing instrument client selects some high photographing instrument equipment, and after clicking on button of taking pictures, high photographing instrument client is by equipment
Title and photographing command are sent to high photographing instrument serve end program, and high photographing instrument serve end program is carried by windows systems
TWAIN protocol dynamic libraries, high photographing instrument is operated, take pictures and picture is stored in the catalogue that client specifies；
4）After high photographing instrument service end grabs picture, picture is sent to by high photographing instrument client by socket.
