Problems solved by technology
However, due to the limited computing power of the industrial computer, an industrial computer with the best performance can only realize a small amount of image splicing, which limits the number of splicing units.
Since the splicing screen processors in the current market must also be processed by supporting splicing software, the processing flow adopts the process of "original signal source - splicing software - splicing screen processor - splicing screen unit", which is cumbersome and inflexible for users to operate. For the software to directly call the display unit display, secondary development must be carried out through splicing software, resulting in high development costs, and potential compatibility issues, and there are hidden dangers for later maintenance and troubleshooting
Most of the existing splicing screen processors use serial ports for management and configuration. This device is bulky, consumes a lot of power, and has many cables, which is not conducive to later maintenance.

The invention discloses a multi-screen image screen-projection method, a terminal, a server and system. The method is characterized by comprising receiving spliced screen attribute information sent by the terminal, wherein the spliced screen attribute information comprises number of display units in the spliced screen, an arrangement mode, and display region size of each display unit; selecting display data according to the spliced screen attribute information, and acquiring an address of the display data; establishing an association relation between the display unit and an address of the display data; and returning the address of the display data and the association relation between the display unit and the address of the display data to the terminal. By use of the method disclosed by the invention, the simple and efficient multi-screen image screen-projection is realized without needing a user to perform excessive adjusting operations, the cost, and the maintenance is easy.
Description
technical field [0001] The invention relates to the technical field of image combination and splicing, in particular to a multi-screen image projection method, terminal, server and system. Background technique [0002] The large-screen splicing product first originated in 1992, which is a splicing wall system using DLP. Later, large-screen splicing products of CRT, DPD, and LCD appeared one after another. In terms of splicing effect, "big screen splicing technology" has also gone through three stages of development: hard edge splicing, overlapping splicing and soft edge fusion splicing. There are two main types of existing large-screen splicing technologies, one is the traditional large-screen display wall hard splicing technology, and the other is the projector seamless splicing technology using edge fusion technology. The large-screen seamless splicing system includes hardware splicing screen processors, high-level projectors and display screens, as well as high-end equi...
