Embodiment Construction

[0023] figure 1 It is a schematic diagram of a laser radar-based stage interaction system in the prior art. The lidar stage interactive system in the prior art includes a lidar detection device 1 , a control host 2 and a stage screen 3 , wherein the lidar detection device 1 is connected to the control host 2 .

[0024] The lidar detection device 1 forms a radial laser scanning surface 11 in front of the performers on the stage, and detects the blocking information of the laser light by the fingers of the performers on the stage or other objects used to determine the polar coordinate information of the touch point 12, and the polar coordinates The coordinate information is transmitted to the control host 2. The control host 2 calculates the spatial position of the touch point 12 according to the polar coordinate information of the touch point 12 and the spatial position information of the lidar detection device 1, and judges whether the display content needs to be updated acco...

Abstract

The present invention discloses a laser radar based stage interaction system. The system comprises at least two laser radar detection devices, a control host and a stage screen, wherein the at least two laser radar detection devices are connected to the control host; the laser radar detection devices form a radial laser scanning surface in front of performers on a stage, detect touch actions on the scanning surface and further locate polar coordinate information of one or more touch points; and the control host calculates the spatial position of the touch point(s) according to the polar coordinate information of the touch point(s) and spatial position information of the corresponding laser radar detection devices. Therefore, by using the system provided by the present invention, real-time interaction between the performers on the stage and the stage screen can be achieved; the problem of decreased detection accuracy of a remote end can be solved; and the detectable amount is effectively enlarged.

Description

technical field [0001] The invention relates to human-computer interaction technology, in particular to a stage interaction system. Background technique [0002] Human-Computer Interaction Techniques (Human-Computer Interaction Techniques) refers to the technology of realizing human-computer dialogue in an effective way through computer input and output devices. Enter the relevant information on the input device. Now, the touch interaction technology represented by smart phones and tablet computers enables people to obtain a very excellent interactive experience when talking with machines. [0003] However, with the further extension of the human-computer interaction technology, the interaction means and interaction design have new content, and the disadvantages of the traditional touch interaction technology (resistive screen, capacitive screen, infrared grating screen, etc.) The range of reach and the area of ​​the touch screen itself are limited, and it is difficult to ...
