Projected image real-time correction method based on planar screen

Abstract

The invention discloses a projected image real-time correction method based on a planar screen. The method includes the steps: S1, projecting an original image on the planar screen; S2, capturing a projected image by a monocular camera; S3, subjecting the projected image captured by the monocular camera to three-dimensional reconstruction; S4, judging whether the image is deformed or not; S5, if the image is not deformed, directly displaying the original image without processing the image; if the image is deformed, obtaining a corrected original image through an image correction procedure, and projecting the corrected original image onto the screen to realize normality in image display; on the basis of real-time correction, if the image correction procedure is not terminated, repeating the above steps until real-time correction of the image is realized. By the projected image real-time correction method based on the planar screen, receiving of the image information captured by the camera, analyzing of the image information and processing and displaying of the image are realized.

Description

technical field The invention relates to a method for real-time correction of projected images based on a flat screen. Background technique Now, projection technology is becoming more and more popular in education, training, entertainment, simulation and other fields. During the use of the projector, the projector cannot be moved after its position is fixed to ensure the correctness of the projected image. However, in moving vehicles, such as airplanes, ships, and buses, it is difficult to ensure that the position of the projector does not change. When the position or projection angle of the projector changes, it is necessary to manually adjust the projector to meet It will be a very cumbersome task to meet the needs of the user's viewing habits. The real-time correction of planar projection requires a camera as an auxiliary tool. The main job of the camera is to obtain the projection information of the current screen, that is, the degree of deformation of the projected p...
