Embodiment 1

[0022] This embodiment discloses an image splicing processor, such as figure 1 As shown, it is equipped with a switching card and its connected input card, output card and control card, and the control card is also connected with the input card and output card. Wherein, the channel type corresponding to the connection may be divided into a data channel and a signaling channel. In image mosaic processing, usually, the channels connected between the control card and the input card, output card and switching card include signaling channel and data channel, the signaling channel is used for signaling transmission and interaction, and the data channel can be used for the base map Data transmission such as transmission; and the connection between the switching card and the input card and output card is mainly a data channel for data exchange.

[0023] Optionally, the switch card can be a traditional cross point switch, the core of which is an X×Y cross point electronic switch, and ...

Embodiment 2

[0048] Corresponding to the foregoing device embodiments, this embodiment discloses a processing method applied to the foregoing image splicing processor. Such as figure 2 As shown, the method includes:

[0049] Step S1, creating a data channel chain, the data channel chain at least including at least one type of cascaded data channels of types A, B, and C.

[0050] In this step, the type A cascade data channel is a cascade data channel directly connected between the first input card and the second input card; the type B cascade data channel is directly connected between the first output card and the second output card The cascading data channel of type C; the cascading data channel of type C is a directly connected data loopback channel for the first output card and / or the second output card to return data to the switching card.

[0051] Preferably, before this step, a client connected to the control card is provided (the client can be embedded in the control card, or can ...

Abstract

The present invention discloses an image splicing processor, to increase the usage of a switch card interface. The image splicing processor is provided with a switch card and an input card connected therewith, an output card and a control card. The control card is further connected with the input card and the output card, and the image splicing processor is further provided with at least one of the following A, B, C types of cascade data channels the input card includes a first input card and a second input card; the A type cascade data channel is a cascade data channel directly connected between the first input card and the second input card; the output card includes the first output card and the second output card; the B type cascade data channel is a cascade data channel directly connected between the first output card and the second output card; the output card includes the first output card and the second output card; and the C type cascade data channel a data loopback channel directly connected for the first output card and / or second output card to return the data back to the switch card.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an image splicing processor and a processing method thereof. Background technique [0002] The large-screen splicing system is widely used in public security alarm, traffic command, power dispatching, monitoring of government departments, command and monitoring of telecommunications and entertainment venues, centralized dispatching and communication systems. It refers to a high-resolution video wall composed of projectors, liquid crystal or LED displays as display units and image splicing processors. Through the control of the image stitching processor, window opening, roaming, superimposition and zooming of each picture can be realized. The image splicing processor is the core device of the large-screen splicing system. It usually has multiple outputs such as VGA or DVI, and each output is connected to a display unit. The image information in the whole system is gathe...
