Embodiment Construction

[0038] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0039] The present invention provides a multi-projection image display method, such as figure 1 As shown, the method includes the following steps:

[0040] S1. According to a predetermined projection arrangement sequence, the projection device arranged first performs projection display on the saved image.

[0041] According to a predetermined projection arrangement sequence, firstly, the projection device that performs the first arrangement projects and displays the images stored therein. Specifically, the projection arrangement order is as follows: sequentially splicing and displaying...

Abstract

The invention provides a multi-projection image display method and a system. The method comprises the following steps: carrying out projection display on a stored projection image by a first projection device; obtaining the image information projected by the front projection device by the rear projection device, using the obtained image as a fused or splicing target image in sequence, matching feature points of the target image and a to-be-projected image, obtaining a hyomography matrix according to a matching result, adjusting the to-be-projected image according to the hyomography matrix, and carrying out fused or splicing display on the to-be-projected image and the target image. According to the method and the system provided by the invention, the projection image is automatically corrected by the machine vision image algorithm, so that a plurality of machines can play an ultra wide image in a working state, the ultra wide image improves the projection brightness, and convenience is provided for a user to carry out projection display on ultra wide, ultra large or ultra high images by using a miniature projector.

Description

technical field [0001] The present invention relates to the technical field of image display control, in particular to a projection display method and system thereof. Background technique [0002] At present, there are many miniature smart projectors popular in the market. Their projection functions are basically the same as those of traditional projectors, but there are differences in projection quality and projection brightness. Therefore, they are widely used in homes or small meetings. Smart projectors are limited by the optical path design and projection power. If you need to play ultra-wide-frame images / video content, or perform large-area projection in a small indoor space, or use it in a brighter environment, there will be various problems. Restrictions affect the playback effect. [0003] Therefore, prior art awaits further improvement. Contents of the invention [0004] In view of the deficiencies in the above-mentioned prior art, the purpose of the present inv...
