Interactive projection method, device and system

Abstract

The invention provides an interactive projection method, device and system. The method includes the steps that an image is projected; the projected image is acquired, a characteristic point is selected, position information of the characteristic point is selected, a coordinate transformation model is built and parameter information is obtained; projected image information including gesture action points is acquired in real time, and corresponding position information is obtained; corresponding control is executed in the corresponding position on an original data input interface. According to the interactive projection method, device and system, the gesture action points in the projected image can be accurately recognized, and the limitation that the projection environment changes continuously is avoided.

Description

technical field [0001] The invention relates to the field of projection, in particular to an interactive projection method, device and system. Background technique [0002] Interactive projection is a popular multimedia display platform in recent years. Using computer vision technology and projection display technology, users can directly use their feet or hands to interact with the virtual scene on the projection area to create a dynamic interactive experience. The interactive projection system collects and shoots the target image through the image acquisition device, and then processes it by the image data processing system to identify and judge the target gesture action point. It has the characteristics of natural, concise and direct. Visual monitoring and other fields have broad application prospects. [0003] However, the gesture recognition applied in existing portable human-computer interaction products, such as projection interactive mobile phones, is mainly based o...

AI Technical Summary

Problems solved by technology

[0003] However, the gesture recognition applied in existing portable human-computer interaction products, such as projection interactive mobile phones, is mainly based on infrared technology, which calculates and determines the point of gesture action by detecting whether there is an obstacle in a fixed plane area, and the interaction effect is affected by factors such as constant changes in the projection environment. Due to the limitation of dynamic gestures, it is difficult to locate accurately in real time, and it is impossible to realize human-computer interaction anytime and anywhere.
