摘要： Determining a rectangular area with a given aspect ratio within a global boundary formed by multiple projectors. An iterated process is repeated at moved locations along the global boundary, until a stopping condition is met. According to the iterated process, a point at a location of the global boundary is selected, a minimum rectangle with the given aspect ratio is grown from identified directions, and the largest rectangle encountered is delivered when the stopping condition has been met. For each such direction, the minimum rectangle is grown in the direction from the selected point until it intersects with a boundary, the grown rectangle is grown in another direction responsive to a determination that the grown rectangle can grow in another direction. The largest rectangle encountered previously is replaced, responsive to a comparison which indicates that the grown rectangle is larger than the largest rectangle encountered previously.

摘要： A projector array includes a plurality of projectors, which together project images into a projection area on a projection surface. Aspect ratios are normalized for all of multiple images designated for display. The normalized aspect ratios are aligned at a common central point. An aspect ratio of a minimum rectangular shape is determined that will encompass all of the aligned aspect ratios. A maximum rectangular projection area is determined within the projection area having the same aspect ratio as the minimum rectangular shape. The center of the maximum rectangular area is designated as a centralization point. Each of all of the multiple images is sequentially projected into the projection area. Each image is scaled for display at its aspect ratio and is displayed centered at the centralization point.

摘要： Control of a multiprojector system having multiple projectors arranged in a projector array. It is determined whether the projector array is positioned to form one object or two or more objects. A first keystone correction mode is selected if it is determined that the projector array is positioned to form one object. A second keystone correction mode is selected if it is determined that the projector array is positioned to form two or more objects. In the first keystone correction mode, a homography transformation for each of the projectors is derived so as to accommodate keystone correction of all projectors in the projector array involved in the projection of the single object. In the second keystone correction mode, a homography transformation for each of the projectors is derived so as to accommodate keystone correction of all projectors involved in the projection of each object.

摘要： A projection system distributed on a network, the projection system comprising a projection server and at least one projection client. The projection client hosts a projector array of multiple projectors which together project a tiling of an image onto a projection surface. The projection server accepts an incoming request from the projection client via the network, the request providing the projection server with area information for a projection area of the projector array onto the projection surface. The projection server determines a layout for the image by calculations using the area information. Layout information based on the layout is transmitted via the network to the projection client in response to the request, and image data is projected in accordance with the layout information received from the projection server.
