A mapping method for a fulldome display, wherein the fulldome display comprises at least one first displaying module, at least one second displaying module, at least one first receiving device connected to the at least one first displaying module, and at least one second receiving device connected to the at least one second displaying module;
- the at least one first displaying module has a plurality of display pixels, and the at least one second displaying module has a plurality of display pixels;
- the at least one second displaying module has a first area and a second area;
- the mapping method comprising steps of:
- converting an original image into a deformed image corresponding to the fulldome display;
- dividing the deformed image into at least one first image, at least one second image, and at least one third image, wherein the at least one first image corresponds to the at least one first displaying module;
- the at least one second image corresponds to the first area of the at least one second displaying module and the at least one third image corresponds to the second area of the at least one second displaying module;
- incorporating the at least one third image with the at least one second image to form at least one intermediate image, wherein a plurality of image pixels of the at least one second image comprises at least one first valid image area and at least one invalid image area;
- a plurality of image pixels of the at least one third image comprises at least one second valid image area;
- wherein a number of image pixels in the at least one second valid image area of the image pixels of the at least one third image is smaller than or equal to a number of image pixels in the at least one invalid image area of the image pixels of the at least one second image, so that when the at least one third image is incorporated into the at least one second image, the at least one second valid image area of the image pixels of the at least one third image is incorporated into the at least one invalid image area of the image pixels of the at least one second image to form the at least one intermediate image;
- displaying a plurality of image pixels of the at least one first image on the display pixels of the at least one first displaying module of the fulldome display based on a first mapping relation by the at least one first receiving device, and displaying a plurality of image pixels of the at least one intermediate image on the display pixels of the at least one second displaying module of the fulldome display based on a second mapping relation by the at least one second receiving device, wherein the at least one second receiving device displays a part of the image pixels of the at least one intermediate image, which originally belongs to the at least one first valid image area of the at least one second image, on the display pixels of the first area of the at least one second displaying module based on the second mapping relation, and displays another part of the image pixels of the at least one intermediate image, which originally belongs to the at least one second valid image area of the at least one third image, on the display pixels of the second area of the at least one second displaying module based on the second mapping relation.
