Embodiment Construction

[0041] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0042] Such as figure 1 As shown, the hardware equipment used in the inventive method includes: intelligent mobile terminal 9, computer (including controlled machines 1, 2, 3 in the computer cluster network, and main control machine 4), projectors 5, 6, 7, Wireless router 8, large screen 11, etc., controlled machines 1, 2, 3 are connected with projectors 5, 6, 7 through connection lines 13, 14, 15; The whole system uses the smart mobile terminal as the foreground user interface, and transmits the geometric correction data generated by user interaction to the computers in the cluster in real time for recalculation of the projection surface and real-time display on the large screen. The wireless router not only needs to connect the master computer and the controlled computer through the LAN interface to meet the needs of real-time and fast info...

Abstract

The invention relates to an interactive multi-channel projection geometric correction method based on an intelligent mobile terminal. The method comprises the following steps that: (1) equipment in a system is started, and the intelligent mobile terminal is accessed to a computer network; (2) a user holding the intelligent mobile terminal stands in front of a splicing screen and performs geometric correction; (3) a geometric correction program of each controlled computer is run, the user determines projection channels to be corrected by observing the alignment status of interpolation points, an auxiliary line and an auxiliary geometric pattern in the overlapping area of neighboring projection channels on a projection screen, and chooses all interpolation points on a geometric correction auxiliary software interface of the intelligent mobile terminal, and the all interpolation points of the projection channel are displayed on the auxiliary software interface; (4) the user chooses the interpolation point to be adjusted in the channel through the intelligent mobile terminal and adjusts the screen coordinate of the selected interpolation point to make the screen coordinate of the selected interpolation point coincide with the corresponding interpolation point of the other projection channel, the projection plane is recalculated by the controlled computer and a calculation result is stored by the controlled computer; and (5) the geometric correction of other channels is finished by repeating the step (3) and the step (4).

Description

technical field [0001] The invention relates to an interactive multi-channel projection geometric correction method based on an intelligent mobile terminal, in particular to an interactive multi-channel projection geometric correction method based on an intelligent mobile terminal in the field of virtual reality and film and television entertainment, belonging to computer network clusters and large Screen splicing display technology field. Background technique [0002] There are usually two implementation methods for multi-channel projection, hardware implementation and software implementation. The hardware implementation method is fast but expensive, and the flexibility is insufficient, so it is difficult to carry out secondary development according to the specific needs on the basis of the original system; the software implementation method uses consumer-grade PCs to form a computer cluster network, which is cheap and realizes multi-channel projection through software.
