Embodiment

[0038] like figure 1 As shown in Fig. 1, a convenient touch interaction system based on image processing technology, the user uses palms, books, printouts, whiteboards and other surfaces as interactive carriers, and can move the interactive carrier naturally, and the system can track it and adjust the interactive interface Display on an interactive carrier. By clicking the interactive interface displayed on the interactive carrier with a finger, a series of operations can be completed. With the palm as the interactive carrier, the problem to be solved urgently is how to recognize the fingertips under the interference of the background of the same skin color, and ensure the recognition rate that can meet the requirements. The portable touch interactive system based on image processing technology includes projector 4, camera 3, processing center 2 and steering gear pan / tilt 1, and processing center 2 is connected to projector 4, camera 3, steering gear pan / tilt 1 respectively, ...

Abstract

The invention relates to a portable touch interactive system based on an image processing technology and is used for performing human-machine interaction on an interactive carrier. The portable touch interactive system comprises a projector, a camera, a processing center and a steering engine holder, wherein the processing center is respectively connected with the projector, the camera and the steering engine holder; the steering engine holder is connected with the projector and the camera respectively, tracks the interactive carrier, controls the projector to project an interactive interface on the interactive carrier, and simultaneously controls the shooting angle of the camera; the camera shoots the human-machine interaction process and sends images to the processing center; and the processing center preprocesses the received images and recognizing gestures of a person by a fingertip recognition algorithm. The steering engine holder tracts the interactive carrier, and fingertips are recognized by the novel fingertip recognition algorithm, so that compared with the prior art, the portable touch interactive system has the advantages that the portable touch interactive system is portable, high in recognition rate, easy to implement and convenient to configure.

Description

technical field [0001] The invention relates to a human-computer interaction system, in particular to a portable touch interaction system based on image processing technology. Background technique [0002] At present, various mobile Internet terminals have become an indispensable part of people's lives, such as smart phones, tablet computers, etc. These terminals have gradually become the main means of Internet access for modern people. Even in today's developed areas, smart terminals such as IPad are gradually entering the classrooms of primary and secondary schools, replacing the original textbooks. At the same time, people have put forward higher requirements for mobile smart devices. Such as more portable, more convenient to use and so on. The traditional interaction methods mainly include keyboards, resistive and capacitive touch screens, etc., but the traditional interactive methods have great limitations. For example, hands cannot be freed during use; the screen ha...
