Embodiment Construction

[0048] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0049] One of the core concepts of the embodiments of the present application is to correct each corner of the original image by obtaining the correction parameters, calculate the clipping line of the original image through the corrected corner coordinates, and finally use the clipping line to clip the original image.

[0050] refer to figure 1 , which is a schematic diagram of correcting the original input image according to the projection area image of the screen in this application. Among them, in 1-1, the frame area is the original input image, the gray area in the middle is the corrected input image, and the black area is the filled area after correction. In 1-2, the outer frame area is the project...

Abstract

The embodiment of the application provides a projected image correction method. The method comprises the following steps: acquiring an original image and a correction parameter input by a user; performing angular coordinate correction on each corner of an original image by the correction parameter in order to determine a correction coordinate of each corner; calculating a shear line of the original image by the correction coordinate; and shearing the original image by the shear line. According to the embodiment of the application, an image shape projected onto a screen is changed by correction of the original image, so that an image projected onto the screen does not need to be debugged by adjustment of the position of a laser television body.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to an image deformation method and an image deformation device. Background technique [0002] Laser TV is a new product that combines laser light source and ultra-short-throw projector technology. The projector can project vertically upwards. It can project a large-size screen when placed on the TV cabinet close to the wall. In order to display the image perfectly, it needs The parallel relationship between the projection plane and the laser reflection mirror is very strict. [0003] When installing a laser TV, professionals are required to adjust the position of the fuselage, and then fix the fuselage to the TV cabinet with screws so that the projection matches the screen. Its installation is complicated, which is not conducive to users' self-installation, and once the fuselage is fixed, the placement position will be limited. But if the fuselage is not fixed, ...
