Problems solved by technology

The image correction function of the known projection device is often too cumbersome to operate, and the user must adjust the projected image multiple times so that the projected image can conform to the predetermined projection area, and the user manually adjusts it It is always difficult to achieve the precise projection position
[0003] And if the user needs to project an image with a specific irregular shape, the commonly used projection device does not have this function

Abstract

A projection system comprises an image capturing device, a processor device and a projection device. The image capturing device is used for capturing a first image of a projection surface. The first image includes a plurality of positioning images. The processor device is used for receiving the first image. The processor device calculates a plurality of positioning points according to the positioning image. The projection device is used for projecting the second image to the projection plane according to the positioning point. The second image includes a plurality of deformation points. And the number of the deformation points on the projection surface is consistent with that of the positioning points, so that the projected image can be automatically adjusted to a range predetermined by auser.

Description

technical field [0001] The present invention relates to a projection system and its image projection method, and in particular to a projection system capable of adjusting projected images according to images captured by an image capture device and its image projection method. Background technique [0002] A projection device is a device that can project images onto a projection screen for presentation to users. The image correction function of the known projection device is often too cumbersome to operate, and the user must adjust the projected image multiple times so that the projected image can conform to the predetermined projection area, and the user manually adjusts it It is always difficult to achieve the precise projection position. [0003] And if the user needs to project an image with a specific irregular shape, the commonly used projection device does not have this function. Therefore, how to quickly and automatically adjust the image projected by the projection...
