Embodiment

[0021] refer to figure 1 , figure 2 , the workflow of the present invention is as follows,

[0022] Output test image: After placing the first projector 8 and the second projector 9 at the same level, the custom control module 12 and the machine vision processing module 10 control the first video image fusion processing module 4 and the second video image fusion processing The module 5 generates a test image, which is output and displayed by the first projector 8 and the second projector 9 .

[0023] Collecting images once: the camera module 11 collects images and transmits the data to the machine vision processing module 10 .

[0024] Calculating rough parameters: the machine vision processing module 10 calculates the roughly estimated size of the fusion region after image binarization, gradient operator and edge detection.

[0025] Update the fine-tuning image: the machine vision processing module 10 updates the image produced by the first video image fusion processing m...

Abstract

The invention discloses a self-adaptive projection fusion device. The self-adaptive projection fusion device includes an HDMI video input module, a DDR3 video data caching module, a video segmentationmodule, a first video image fusion processing module, a second video image fusion processing module, a first HDMI video output module, a second HDMI video output module, a first projector, a second projector, a machine vision processing module, a camera module and a user-defined control module. The machine vision processing module is matched with the camera module to dynamically identify a videofusion area, a video is segmented according to an identification result, and the video is output and displayed by equipment such as a projector after fusion preprocessing. A plurality of videos with common resolutions are output through a plurality of common projectors, and then are displayed as a high-resolution, high-brightness and large-picture video through boundary fusion, so that a high-costengineering projector is replaced;the fusion area can be recognized in a self-adaptive mode, the video fusion area is processed, and therefore the projection fusion device is easier to operate and the higher in flexibility.

Description

technical field [0001] The invention relates to a projection device in the technical field of machine vision, in particular to an adaptive projection fusion device. Background technique [0002] In modern society, video technology is closely related to people's life, and the pursuit of larger picture, higher resolution, more realistic color and ultra-high brightness is becoming more and more intense. The highest resolution supported by the display devices of household TVs, computer monitors, and theater projectors in the prior art is 4K, and there are problems such as insufficient brightness and insufficient definition while the screen size is limited. In the application scenarios of other large display screens other than homes and theaters, such as: large-scale monitoring and command centers, product launches, and multimedia exhibitions, the demand for ultra-high-resolution, ultra-large-size images is more urgent. High-lumen, high-resolution engineering projectors can well...
