Desktop interaction projection system and control method

Abstract

The invention provides a desktop interaction projection system and a control method. The interaction projection system comprises an image projection module, an image analysis module, infrared laser, an infrared induction module, a wireless power supply module, a Bluetooth module and a signal processing module. By use of the control method, a user is subjected to real-time capture and shooting, then, an information processor carries out quick and accurate analysis so as to generate the movement of a captured object, the movement corresponds to various input functions, movement data is combinedwith a real-time image interaction system, and therefore, a participant and a projection screen generate a tightly combined interaction effect. Meanwhile, the infrared induction module automatically detects whether a user is in the presence or not, in addition, intelligent mobile equipment can access projection through the Bluetooth module, the power supply of the whole device is uniformly provided through the wireless power supply module, energy is stored through wireless charging, and operation is convenient.

Description

technical field [0001] The present invention relates to the field of interactive projection, in particular to an interactive projection system and control method capable of realizing interaction on a desktop. Background technique] [0002] Interactive projection equipment, also known as projection equipment that can complete input on the projection surface in real time. With the popularization of the use of projection equipment, the advantages of interactive projection over ordinary projection are more obvious. With the development of science and technology, interactive projection equipment mainly used in teaching has emerged. This type of projection belongs to wall projection. It is used together with the matching curtain and laser pointer equipment. It can write and leave comments on the projection surface with a laser pointer while projecting. , but this type of input is an additional input, which has no effect on the projection content, but is only projected at the same...

AI Technical Summary

Problems solved by technology

However, these types of interactive projections need to be fixed in advance before use, because they cannot be moved because they need to be connected to a power source, and they are bulky and inconvenient to carry

The projection content and projection input area of ​​the above projections are too fixed and cannot be changed at any time according to user needs to apply to various scenarios

Moreover, the above-mentioned projection device is limited by the projection focal length, and can only be used by multiple people in large-scale occasions, and cannot be used by a single person anytime, anywhere.

At present, most of the new interactive projection devices are wearable devices, which can only complete relatively simple input functions and are not practical.

In restaurants or libraries, there is no interactive projection for ordering dishes or flipping books, so a small desktop interactive projection device is urgently needed
