Embodiment 1

[0019] This embodiment discloses an image stitching processor.

[0020] Such as figure 1 As shown, the image splicing processor disclosed in this embodiment includes: at least three card slots connected sequentially to data channels on its backplane, one card slot is for the control card, and the remaining at least two card slots are for at least two The input cards are sequentially cascaded to form an input card chain, and the input card slot at the end of the input card chain is arranged adjacent to the control card slot. For ease of description, the present invention marks the data channel of the input card chain cascade and the data channel between it and the control card as the first type of data channel.

[0021] In this embodiment, the above-mentioned input card can usually be connected to a single or multiple external signal source and perform input processing on it. The input processing includes but is not limited to one or more combinations of subsequent processing: input...

Embodiment 2

[0026] This embodiment discloses an image stitching processor.

[0027] Such as figure 2 As shown, the image splicing processor disclosed in this embodiment includes at least three card slots connected sequentially to data channels on its backplane, one card slot is used for the control card, and the remaining at least two card slot portions are for at least two The output cards are sequentially cascaded to form an output card chain, and the output card slot at the head end of the output card chain is arranged adjacent to the control card slot. As in the first embodiment, the present invention also records the cascaded data channel in the output card chain and the data channel between it and the control card as the first type of data channel.

[0028] In this embodiment, the above-mentioned output card can usually process the single-channel or multi-channel signals transmitted by the switching card and then output to the corresponding splicing wall display unit. The output process...

Embodiment 3

[0032] This embodiment discloses an image stitching processor.

[0033] The image splicing processor disclosed in this embodiment has at least five card slots connected to the data channels in sequence on its backplane, one card slot is used by the control card, and the remaining at least two card slots are used for at least two input cards to be cascaded sequentially Form an input card chain, and the input card slot at the end of the input card chain is arranged adjacent to the control card slot; the remaining at least two card slots are for at least two output cards to be sequentially cascaded to form an output card chain, and the output card chain The output card slot at the head end is arranged adjacent to the control card slot.

[0034] Among them, the cascaded data channel in the input card chain and the output card chain and the data channel between it and the control card are collectively called the first type data channel.

[0035] In this way, the first-type data channel d...

Abstract

The invention discloses an image splicing processor and an image processing method thereof, so as to improve the cost performance and expansibility of the image splicing processor. In the image processor disclosed by the present invention, at least three card slots connected in sequence by data channels are arranged on the backboard, one card slot is used for the control card, and the remaining at least two card slots are arranged as follows: for at least two input cards in sequence Linked into an input card chain, and the input card slot at the end of the input card chain is adjacent to the control card slot; and / or at least two output cards are sequentially cascaded into an output card chain, and the output card chain The output card slot at the head end is set adjacent to the control card slot; wherein, the data channel cascaded in the input card chain and / or the output card chain and the data channel between the control card and the control card are marked as the first class data channel.

Description

Technical field [0001] The invention relates to the technical field of image processing, in particular to an image splicing processor and an image processing method thereof. Background technique [0002] Image splicing processors are widely used in municipal units and enterprises as applications in formal occasions such as information release, real-time monitoring, and conferences. The existing image splicing processor usually includes a switch card (or called a switch module) and its connected input card (or called an input module), which is used for data processing of input signals, including signal adaptation, frame rate and resolution adjustment ), output card (or called output module, used for data processing of output signals, including window overlay, etc.) and control card (or called control module). The control card is also connected to the input card and output card. In specific splicing, the input cards 1 to n are used to convert the original data of each input source...
