Multi-element desktop projection interaction realization method and device

Abstract

The invention discloses a method and a device for realizing multi-element desktop projection interaction. The device comprises a desktop, a projector, a computer and a depth camera, the depth camera is positioned right above or obliquely above the desktop; the projector is located above the desktop, and a picture projected on the desktop is not deformed; the method mainly comprises the necessary steps that S1, a depth map image signal and a desktop projection picture are aligned; s2, a depth map position corresponding to any pixel position in the projection picture can be accurately found, so that pixel-level fine interaction is realized; s3, tracking and identifying different objects on the desktop; the system is suitable for various catering, education and entertainment venues, provides a more accurate and finer desktop projection interaction signal processing method, is convenient to install and use, and can promote commercial activities to attract popularity, promote consumption, increase novelty of child projection interaction products, increase cognitive efficiency and improve interaction experience.

Description

technical field [0001] The invention belongs to the technical field of projection interaction, and in particular relates to a method and device for realizing multi-element desktop projection interaction. Background technique [0002] The desktop interactive projection system is an interactive system for advertising and entertainment that integrates the highest technology in the world; the interactive audio-visual system provides an unusual and exciting effect system for advertising and entertainment. It is suitable for all public indoor places, especially for leisure, shopping, In entertainment and educational places, the operating principle of the interactive projection system is to first capture and shoot the target image through the capture device, and then analyze it by the image analysis system to generate the motion of the captured object. Create a close interaction with the screen; [0003] The current desktop projection interaction, its signal sources mainly fall in...

Problems solved by technology

However, none of them can achieve pixel-level fine projection interaction, such as probing into any contour position of the hand in the screen to make a butterfly in the projection screen avoid flying away;

[0004] 2) Detection of depth image changes based on the depth camera: the continuous motion position signal of an object cannot be fixedly tracked; pixel-level fine projection interaction cannot be realized, and the depth camera must be installed vertically above the desktop;

[0005] 3) Bas
