Problems solved by technology

Therefore, the traditional projection display device does not have the rich functions similar to PDA.
[0004] In terms of mobile phone projection, although there are products that directly embed the projection lens into the mobile phone, there are still shortcomings such as poor projection quality, lack of integration of existing projection resources, and lack of adaptability.

Embodiment Construction

[0029] Hereinafter, the present invention will be further described in detail with reference to the examples and drawings, but the implementation of the present invention is not limited thereto.

[0030] The human-computer interaction projection method for visual processing based on Android includes the following steps:

[0031] S1. The projector projects the picture in the Android device onto a predetermined area, and the camera collects the original image in real time in the predetermined area, and transmits the collected original image in RGB888 format to the microcontroller; at the same time, the infrared laser tube is directed to the predetermined area Emit infrared light; the camera is equipped with an infrared filter;

[0032] S2. Change the original image collected in the microcontroller from RGB888 format to YUV422 format;

[0033] S3. Take out the Y score in the YUV422 format image, and binarize the Y score to obtain the final image: if there are no hands in the predetermine...

Abstract

The invention discloses a method for visual processing human-machine interactive projection based on Android. The method comprises the following steps of enabling Android equipment to access into a projector through an HDMI (high-definition multimedia interface), and enabling the projector to project an Android interface onto a plane in real-time and high-definition ways; enabling embedded visual processing equipment to collect an image of a finger on a screen in real time, and finding the contour of a hot spot; filtering to obtain the finger coordinate of the effective operation; enabling the embedded visual processing equipment to access into the Android equipment through an USB (universal serial bus) interface; enabling an USB response function to process the finger coordinate obtained by the embedded visual processing equipment in real time, so as to operate an operation interface of the Android equipment in real time. The method and the system have the advantages that the operation disengaging from a host end is realized, the operation is easy, convenient and free, the physical operation sense is strong, and the like.

Description

Technical field [0001] The present invention relates to the field of human-computer interaction, in particular to an Android-based visual processing human-computer interaction projection method and system. Background technique [0002] There are two trends in the current technological society, the popularization of the Android platform and the increasing demand for projection image technology. Android is a free and open source operating system based on Linux, mainly used in mobile devices, such as smart phones and tablets. Because the portability of Android system devices is destined to have smaller screens and poor experience, it is necessary to use projection technology to project the interface of the Android device during work or entertainment. At the same time, people will control the Android operating system through embedded vision processing human gestures This system will greatly facilitate people’s work and life, and will be a revolutionary innovation. [0003] Nowadays, ...
