Public place image real-time projection method and system

Abstract

The invention provides a public place image real-time projection method and system. The method comprises the steps: carrying out the analysis and processing of a photographed public place environment image, determining the personnel existence state information and projectable region range information of a public place, and correspondingly obtaining a projection position and a projection area corresponding to image projection; and finally, adjusting the projection resolution and / or projection contrast of the current image projection in combination with the projection position and the personnel existence state information, so that image viewers in different areas can view clear projection images without obvious aberration deformation. Therefore, the automation degree and the intelligence degree of image projection in public places are effectively improved.

Description

Technical field

[0001] The present invention relates to the technical field of image projection, and in particular, to public places, real-time projection methods and systems.Background technique

[0002] At present, the image projection is performed in a dedicated projection screen, and the area of ​​the projection screen is large and the need to be set on the corresponding plane to achieve high quality image projection. However, in a general public place, there is no dedicated projection screen to receive a projected image, which can only project the image in a blank wall area corresponding to the public place, and the position of the people in public places is more frequent and the corresponding blank wall. The surface area does not match the projection position / projection area demand, which puts higher requirements for real-time projection of high quality images in public places. The prior art urgently needs high quality, high projection clarity, and video real-time projection modes...
