Projection interaction method, projection interaction device and intelligent terminal

Abstract

The invention discloses a projection interaction method, a projection interaction device and an intelligent terminal. The method comprises steps as follows: receiving a gesture image captured by a camera in a projection process; acquiring a projection image at the same moment with the gesture image, and magnifying the projection image to the same size with the gesture image; comparing the magnified projection image with the gesture image, and cutting different areas of the two images to serve as target areas; performing static gesture recognition on the target areas, extracting gestures in the target areas, and matching the gestures with preset gesture templates to obtain commands corresponding to the gestures; controlling the projection process according to the obtained commands. Only the target areas are subjected to gesture recognition processing, so that image processing area is greatly reduced, image processing time is shortened, then the gesture recognition efficiency is improved, the problem of time delay caused by the fact that the corresponding commands are executed through gesture recognition is effectively solved, and user's experience is enhanced.

Description

technical field [0001] The present invention relates to the technical field of projection, and in particular, to a projection interaction method, a projection interaction device and an intelligent terminal. Background technique [0002] In the pursuit of high-efficiency, fast-paced modern office and modern life, projection technology has been widely used as a new type of office technology. Projection technology can not only be used in temporary meetings, technical lectures, network centers, command and monitoring centers, but also can be connected to computers, workstations, etc., or to video recorders, TVs, DVD players, and physical booths. It can be said that it is an application. Very extensive large-screen imaging technology. [0003] Gesture recognition technology is to accurately end human gestures through computer equipment, which is mainly divided into static gesture recognition and dynamic gesture recognition. Among them, static gesture recognition mainly recogniz...

Problems solved by technology

[0005] In view of the problems that the gesture recognition in the prior art directly processes all the images captured by the camera, the efficiency is low, the time consumption is long, and the processing is difficult, a projection interaction method, projection interaction device and intelligent terminal of the present invention are proposed, in order to solve or at least partly solve the above problems
