Embodiment Construction

[0124] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0125] Before introducing the projection image adjustment method, device, storage medium, and electronic device of the present disclosure, the application scenarios of the present disclosure are firstly introduced, and various embodiments provided in the present disclosure can be applied to projection image adjustment scenarios. Wherein, the projection image may be, for example, an image formed by various types of projectors projecting a source image into a projection area.

[0126] Taking the ultra-short-throw projector as an example, it can project a picture with a diagonal of 250 centimeters at a distance of 50 centimeters from the wall, that is, it can pr...

Abstract

The present disclosure relates to a projection image adjustment method, device, storage medium, and electronic equipment, the method comprising: acquiring a target image obtained by shooting a projection area with a camera; determining a first imaging image and a second imaging image in the imaging coordinate system of the target image Two imaging images; calculate the first mapping relationship between the first imaging image and the source image in the projected coordinate system; calculate the second mapping relationship between the second imaging image and the preset user perspective image; based on the The first mapping relationship and the second mapping relationship map the source image to the user perspective coordinate system; determine the intersection area of ​​the source image and the second imaging image in the user perspective coordinate system, and obtain from the determining a target area in the intersection area; mapping the target area to the projection coordinate system to obtain a target projection area on the projection screen, and adjusting the projection image according to the target projection area.

Description

technical field [0001] The present disclosure relates to the field of projection technology, and in particular, to a projection image adjustment method, device, storage medium, and electronic equipment. Background technique [0002] A projector is a device that can project images or videos onto a screen. It can be connected to computers, game consoles, storage devices, etc. through different interfaces to play corresponding video signals. [0003] Generally speaking, the size of the projected screen is positively related to the distance between the projector and the wall. As for the ultra-short-throw projector, it can project a picture with a diagonal of 250 centimeters at a distance of 50 centimeters from the wall, that is, it can project a larger projection picture in a limited space. However, even if the angle of the ultra-short-throw projector changes by 1° during installation and use, it will cause a huge shift in the projection screen, which affects the user experienc...
