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...
