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

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] Such as figure 1 As shown, the hardware device of the present invention includes a main control computer 3, a projector 2, a laser locator 1, and a projection screen 4. The main control computer 3 is connected to the projector 2 and the laser locator 1 respectively. The projector 2 and the laser locator 1 are aimed at the projection screen 4 respectively.

[0021] 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 start of the project, and adjust the position and correct the surface of the image on the projection screen, and then use the present invention to correct After the image is positioned and recorded on the projection screen, even if the projector and other equipment need to be adjusted later,...

Abstract

The invention relates to curved surface correction information processing method and device based on a laser locator, wherein the method comprises the following steps: 1) firstly, adjusting projection hardware equipment to locate a projector and projection screen equipment at set positions and directions, and performing step 2); 2) correcting a projection image through a main control machine, adjusting the edge fusion part to enable the image to be tangent to the screen, and performing step 3); 3) locating the specific information of the projection image through the laser locator; 4) judging whether to receive a projection equipment adjusting command through the main control machine, if so, performing step 5); and if not, performing step 7); and 5) adjusting the projection equipment and performing step 6), wherein the device comprises the main control machine, the projector, the laser locator and a projection screen. Compared with the prior art, the method and device disclosed by the invention have the advantages of low cost, convenience in operation and accurate locating data.

Description

technical field [0001] The invention relates to a method and device for correcting projection equipment, in particular to a method and device for processing curved surface correction information based on a laser locator. 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 ot...
