Problems solved by technology

[0003] Today's surface correction software has very high requirements for the position and angle of projectors, projection screens and other hardware. Once the projector or projection screen needs to be adjusted during the project, the adjustment and configuration made by the previous surface correction will need to be repeated. Brings a lot of redundant workload

Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] Such as figure 1 As shown, the hardware device of the present invention includes a main control machine 3, a projector 2, a camera 1, a projection screen 4 and a user terminal, and the main control machine 3 is connected to the projector 2, the camera 1, and the user terminal respectively, so that The above-mentioned projector 2 and camera 1 are aimed at the projection screen 4 respectively.

[0020] The present invention provides the positioning of image projection on the projection screen. The user only needs to project the projector onto the projection screen at any time after the project starts, and adjust the position and correct the surface of the image on the projection screen, and then use the present invention to correct the image. Survey the information on the projection screen. If the projector and other equipment need to b...

Abstract

The invention relates to a method and a device for processing projection calibration information on the basis of information feedback. The method includes the steps of 1) adjusting a projector and a projection screen to locate at preset positions and directions, then executing the step 2); 2) calibrating a projected image by a main controller, adjusting edges and integration borders to enable the image to be fit with the screen, and then executing the step 3); 3) acquiring specific information about the projected image by a camera, and the like. The device for processing projection calibration information on the basis of information feedback comprises the main controller, the projector, the camera, the projection screen and a user terminal. The main controller is connected with the projector, the camera and the user terminal respectively, and the projector and the camera are arranged in alignment to the projection screen. Compared with the prior art, the method and the device have the advantages that cost is lower, operation is more convenient, and positioning data is more accurate and the like.

Description

technical field [0001] The present invention relates to a projection correction method and device, in particular to a projection correction information processing method and device based on information feedback. Background technique [0002] In the display and control technology mainly based on splicing, the seamless splicing technology used to realize the seamless fusion display of images is one of the important technologies. Seamless splicing technology is a special projection display application with relatively high requirements, which can realize the fusion of multiple screen images and minimize the splicing gap to completely overlap. In recent years, with the development of software and hardware technology, seamless splicing technology has been widely used in exhibitions, visual entertainment, advertising and other fields. [0003] Today's surface correction software has very high requirements for the position and angle of projectors, projection screens and other hardw...
