Abstract

The method is suitable for the technical field of data processing, and provides a projection interaction method, device and system and terminal equipment, and the method comprises the steps: obtaininga projection image collected by an image collection device on a projection plane, carrying out the processing of the projection image, obtaining a light spot change track of light spots, wherein thelight spots are generated when light rays emitted by a control device irradiate the projection plane; Obtaining an operation track according to the light spot change track and a coordinate transformation relationship between the projection image and a projection operation interface, and generating an operation instruction according to the operation track; And operating the projection operation interface according to the operation instruction. The interactive projection system can solve the problems that an existing interactive projection system is high in projection cost and difficult to carryand move.

Description

technical field [0001] The present application belongs to the technical field of data processing, and in particular relates to a projection interaction method, device, system and terminal equipment. Background technique [0002] With the development of science and technology, interactive projection technology has gradually entered people's lives. The current common interactive projection technology mostly adopts rear-projection projection. The projection screen is connected to the computer. Identification devices such as pressure sensors or grating structures are set in the projection screen. When the stylus or finger touches the projection screen, the projection screen passes After the recognition device detects the position of the stylus or the finger, the operation of the stylus or the finger is input into the computer to operate the projected operation interface instead of the mouse. [0003] However, when using identification devices such as pressure sensors or grating...
