Embodiment Construction

[0017] refer to Figure 1-4 . Taking nine projectors forming a 3*3 projector array as an example, the method for constructing a projection array high dynamic range display system of the present invention specifically includes the following steps:

[0018] 1. Fix 9 projectors with brackets in three rows and three columns, and ensure that each projector can be adjusted horizontally and vertically. In order to facilitate the alignment of the projected images, the 9 projectors are numbered sequentially, namely projector No. 1, projector No. 2, projector No. 3, projector No. 4, projector No. 5, projector No. 6 6, No. 7 projector 7, No. 8 projector 8, and No. 9 projector 9. The fifth projector 5 defining the central position is the reference projector. At the same time, the projection screen 10 is defined. Adjust and fix each projector so that the projection axes of the 9 projectors are perpendicular to the projection screen, and make the projection axes of No.

Abstract

The invention discloses a construction method of a projection array high dynamic range display system, which is used to solve the technical problem of complex construction methods of the existing projection array display system. The technical solution is to install a projector array that is fixed and perpendicular to the projection plane, and adjust the lens displacement of a single projector, so that multiple projectors are aligned and projected to a projection screen without an external controller; They are respectively assigned to the corresponding projectors for projection, so as to obtain natural mixed high dynamic range images. The high dynamic range display system constructed by this method utilizes the lens shift function and the automatic geometric correction function that modern projectors generally have, and eliminates the complicated geometric correction of multiple projectors projecting the same picture. Moreover, the multi-exposure low dynamic range image is naturally mixed and displayed by the projection array to display the high dynamic range image, the method is simple, no color conversion is required, and the dynamic range of the display result can be doubled.

Description

technical field [0001] The invention relates to a construction method of a projection array display system, in particular to a construction method of a projection array high dynamic range display system. Background technique [0002] High dynamic range research mainly includes two parts: high dynamic range imaging and high dynamic range display. The display terminals that can be purchased in the domestic and foreign markets are basically low dynamic range display devices, while high dynamic range display devices are mostly dedicated systems for research purposes. These dedicated high dynamic range display systems are often expensive and in an immature research stage . In order to solve the problem of high dynamic range display, a large number of high dynamic range researchers have devoted themselves to the tone mapping method, which maps high dynamic range images to low dynamic range images for display on low dynamic range display devices. The complexity of dynamic imaging...
