Embodiment 1
[0066] The present invention provides a grid data generation method for multiple projectors to perform projection splicing correction, such as figure 1 shown, including:
[0067] Step 1: Determine the displayed information of the target screen, and at the same time, determine the projection position of each projector based on the target screen based on the displayed information;
[0068] Step 2: Adjust the position of the projector according to the position difference information between the projection position and the preset position, and based on the preset display information, set each projector corresponding to the displayed information at the target The projected data on the screen is corrected;
[0069] Step 3: Generate grid data based on the corrected projected data.
[0070] Preferably, the displayed information includes: the size of the overall display interface on the target screen after projection splicing, the size of the individual display interface projected by...
Embodiment 2
[0077] On the basis of Embodiment 1, in step 1, determining the displayed information of the target screen includes:
[0078] Shooting the target object in real time, and determining the movement information of the target object during the real-time shooting process;
[0079] Constructing a display model based on the target object and the movement information of the target object;
[0080] The display model is transmitted to a corresponding projector for projection to obtain the displayed information, and then determine the displayed information of the target screen.
[0081] In this embodiment, for example, the target object can be composed of a billiard ball and a billiard table, and the movement information is, for example, the rolling track of the billiard ball on the billiard table. Build gets.
[0082] In this embodiment, the preset display information may be obtained based on a display model and is pre-set, and the displayed information is realized by a projector set ...
Embodiment 3
[0086] Based on Embodiment 1, in step 1, determining the projection position of each projector based on the target screen based on the displayed information includes:
[0087] determining a current display model of each projector based on the preset display information;
[0088] Acquiring the displayed information of the target screen, and judging whether the displayed information is completely displayed on the target screen based on the preset display information;
[0089] If it is incomplete, extract the incomplete information, and match the incomplete information with the current display model of each projector to obtain a matched first projector and an unmatched second projector;
[0090] Determine the displayed blur degree and displayed color degree of the current display model corresponding to the unmatched second projector, and determine the position to be adjusted factor of the second projector;
[0091] According to the displayed information, determine the sequential...
