Abstract

The invention provides a large-breadth interactive tabletop synchronization signal acquisition system, which comprises a large-breadth interactive tabletop, a master control computer, a controller, an LED array, a camera array and n signal acquisition computers, wherein the large-breadth interactive tabletop consists of n sub-tabletops; the master control computer is used for transmitting control parameters to the controller and receiving image data from the signal acquisition computers; the controller is used for synchronously controlling the LED array and the camera array according to the control parameters and/or synchronization pulse signals; the LED array comprises n LED units and is used for illuminating the large-breadth tabletop; the camera array comprises 2n cameras and is used for acquiring the image data of the large-breadth interactive tabletop and transmitting the synchronization pulse signals to the controller when a shutter of one camera is taken down; and the n signal acquisition computers are used for processing the acquired image data and transmitting the processed image data to the master control computer. The large-breadth interactive tabletop synchronization signal acquisition system meets requirements on signal acquisition of a large field of view, high brightness and wide angle of field, and keeps synchronous switches of the cameras and LEDs.

Description

technical field [0001] The invention relates to the technical field of signal acquisition, in particular to a large-format interactive desktop synchronous signal acquisition system. Background technique [0002] In recent years, interactive desktop technology has received more and more attention. The interactive desktop provides a harmonious and natural interaction channel between the user and the computer, allowing one or more users to directly interact with multiple points on the display surface of the interactive desktop. Touch input. A robust interactive signal acquisition system is the prerequisite for the stable operation of the entire interactive desktop. [0003] In the signal acquisition method of the interactive desktop, the existing implementation methods include based on the frustrated total internal reflection technology; one long side and short side of the rectangular screen (that is, the interactive desktop) emits infrared signals, and the other long side and...
