Multiprojection display system and screen forming method

摘要

Provided is a multiprojection display system that includes a plurality of cameras configured to capture images of predetermined vertex regions including vertexes of projected images projected from two-dimensional scanning projectors onto a screen, an image-capturing timing control unit configured to control the cameras to capture images of the screen for a predetermine period including a display. start row of one frame of the projected image or a predetermined period including a display end row, and a vertex position detection unit configured to detect vertexes of the respective projected images from data relating to the plurality of images captured by the cameras, and to output data relating to image edges indicating positions of the vertexes. A projector control unit adjusts, when the vertex of the projected image shifts from a present reference position, a scanning range of the two-dimensional scanning projector so that the vertex can be matched with the reference position.

1. A multiprojection display system in which a plurality of two-dimensional scanning projectors project images onto a screen, comprising:
a set of cameras that capture images of predetermined vertex regions including vertexes of said projected images; an image-capturing timing control unit that controls said set of cameras to capture a set of images on said screen during a predetermined period, selected based on a scanning direction or scanning timing of said two-dimensional scanning projectors; a vertex position detection unit that determines, based on the captured set of images, for each of the projected images, an edge that is adjacent to a region outside of the projected image, detects the vertexes of said projected images based on the edge determination, and outputs data indicating positions of the detected vertexes; and a projector control unit that adjusts a scanning range of at least one of the two-dimensional scanning projectors based on a determination that at least one of the detected vertexes is shifted from a reference position of the at least one detected vertex.
