Distributed infrared vision detection and projection fusion automatic correction-based touch display system

Abstract

The invention belongs to the technical field of computer software and projection, particularly relates to a distributed infrared vision detection and projection fusion automatic correction-based touchdisplay system, and aims to solve the problems of a time delay of touch event detection and relatively long time of a splicing fusion process. The system comprises a projection device, a vision collection module, an infrared emitter module, a camera calibration module, a detection processing client, a data fusion module, an image processor, a multi-thread projection rendering module and an automatic projection fusion correction module. According to the system, a touch event of a large touch region can be detected in real time, so that the timeliness of touch detection is ensured; multiple projection images can be rendered at the same time, so that the rendering efficiency is improved; and the establishment, in an early stage of projection fusion correction, and the later maintenance of the system are facilitated.

Description

technical field [0001] The invention belongs to the technical field of computer software and projection, and specifically relates to a touch display system for automatic correction of distributed infrared vision detection and projection fusion. Background technique [0002] With the development of science and technology, the experience of human-computer interaction tends to pursue intelligence, immersion, and interactivity. The large touch screen integrates display and interaction functions. While providing an intuitive interactive experience, it can also support The viewing experience of multiple people at the same time has become a display method widely used in commercial project promotion, museum theme display, game interactive entertainment, etc. At present, the working method of large-scale touch screen is to add a layer of electric signal sensing surface between the glass bottle and the LCD screen to sense the touch of the finger to achieve the effect of real-time dete...
