Problems solved by technology

Existing projectors use one projector in general occasions such as meeting rooms, so the projection brightness is not high, and it is inconvenient to use in practice
However, the existing manual projectors use multiple projections to synthesize and superimpose, which will inevitably cause image distortion, and manual adjustment cannot accurately complete the correction of distortion.

Embodiment Construction

[0028] As shown in the figure, a multi-projection composite optical projection system includes a plurality of projectors 1, a server 21 capable of displaying images, a single-chip microcomputer 22 for signal processing, and a set of projectors arranged on a projection scene 5 and fixed in position with each other. Four photosensitive sensors 3 for positioning the projected image of projector 1, projector 1 is connected and communicated with server 21 through wires, single-chip microcomputer 22 is connected and communicated with server 21 through communication equipment interface 23, there is display 211 on server 21, photosensitive sensor 3 is connected to the single-chip microcomputer 22 through wires. After scanning, the server 21 positions the four photosensitive sensors 3 on the projection scene 5 as the positioning coordinate points of the projected images, so that the projected images of each projector 1 can be positively projected on the city surrounded by the four photo...

Abstract

The invention discloses a multiple projection synthetic optical projection system and a method for projection by utilizing the optical projection system; wherein the multiple projection complex optical projection system comprises a plurality of projectors, a server capable of displaying images, a single chip used for signal processing and four photosensitive sensors which are arranged on projection scenery in fixed relative position and used for positioning images projected by the projector, each photosensitive sensor is connected with the single chip by a wire, the single chip is connected with the server for communication by a communication device interface, and the projector is connected with the server for communication by a wire. The invention aims at providing a multiple projection synthetic optical projection system which adopts two or more projectors to be projected in plane of the same position and realizes synthesis and overlaying of images of a plurality of projectors for improving projection brightness and avoiding projection image distortion as well as method for projection by utilizing the optical projection system.

Description

[technical field] [0001] The invention relates to a multi-projection composite optical projection system and a projection method using the optical projection system. [Background technique] [0002] In existing projectors, generally, manual vertical keystone correction and manual horizontal keystone correction are available, so that the size and position of the projected image can be adjusted on the scene. Existing projectors adopt a projector in general occasions such as a meeting room, so the projection brightness is not high, and it is inconvenient to use it in practice. However, the existing manual projectors will inevitably cause image distortion by using multiple projections to synthesize and superimpose, and manual adjustment cannot accurately complete the correction of distortion. For this reason, it is necessary to improve the projection system of the existing projector. [Content of the invention] [0003] The purpose of the present invention is to overcome the d...
