Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.

Example one

The embodiment provides a virtual interaction method based on a moving head projection lamp, which is applied to a lighting system, wherein the lighting system comprises an Artnet light controller, different stage lamps and projection lamps are connected to the Artnet light controller, and the Artnet light controller is communicated with a lighting system signal of the embodiment, so that light is controlled. In this embodiment, the projection lamp further includes a shaking head projection lamp capable of rotating in the X-axis and Y-axis directions, and meanwhile, the lighting system of this embodiment further includes a scanning recognition device, and the virtual interaction method of this embodiment is implemented by using the scanning recognition device and the shaking head projection lamp.

As shown in fig. 1 and fig. 2, the virtual interaction method of the present embodiment includes the following steps:

step S0: initializing the lighting system to start various projection lamps and scanning identification equipment in the lighting system, and calibrating the scanning range of the scanning identification equipment and the projection range in the lighting system to ensure that the two ranges are coincident.

Step S1: receiving an animation signal of a virtual target object, converting the animation signal according to a data transmission protocol, and mapping the animation signal to the moving head projection lamp for projection display; and acquiring the position information of the virtual target object in the projection display picture in real time.

In the embodiment, the virtual target object is a virtual butterfly, and the animation signal of the virtual target object is 3D model data of the butterfly continuously executing flying motion according to a time line. The user can also replace the animation signal of the virtual object according to the requirement of the user.

The lighting system obtains an Artnet protocol of an Artnet lighting controller, obtains a DMX512 channel value of the moving head projection lamp through the Artnet protocol, and performs one-to-one mapping on the animation signal of the virtual target object and the DMX512 channel value so as to project the animation signal of the virtual target object through the moving head projection lamp after data conversion processing.

The moving head projection lamp obtains XY dynamic coordinates and animation motion orientation in 3D model data of a virtual target object in real time in the projection process, assigns the XY coordinate plus-minus data to the DMX512 moving head projection lamp according to the orientation, enables the moving head projection lamp to change the projection direction according to the flying orientation of the animation in the 3D model, and updates animation dynamic playing and projection lamp channel value animation timeline states in real time so as to display the projection of the moving virtual target object. After the virtual target object is displayed in a projection mode, the lighting system collects the position information of the virtual target object in real time, namely the current dynamic coordinate point of the virtual target object in the projection display picture.

Step S2: and acquiring the barrier signals acquired by the scanning and identifying equipment, and identifying the position information of the specified part of the barrier according to the barrier signals.

In this embodiment, the scanning and identifying device is a radar device, and ensures that the current position of the obstacle falls within the sensing range of the radar device, and the position information of the specified part of the obstacle can be acquired through the radar device. In this embodiment, the obstacle is a human body, and the designated portion of the obstacle is a hand position of the human body; the electromagnetic wave sent by the radar device is reflected by a human body and then processes the received reflected wave, the outline of the human body is identified through computer simulation, the hand position of the human body is selected, and the signal of the hand position is further analyzed.

When the obstacle signal scanned by the radar device is simulated by the computer to be not the human body outline, the step of identifying the position information of the appointed part of the obstacle is not executed, the radar device is enabled to continue scanning, and the step of identifying the position information of the hand position of the human body is not executed until the obstacle is scanned and identified by the radar device to be the human body.

Because a plurality of noise signals are acquired by the radar device and correspond to the positions of the hands of the human body, the noise signals are filtered and suppressed to output single-point signal coordinates of the hands of the human body; and converting the coordinate system of the single-point signal coordinate of the human hand to obtain the single-point signal coordinate of the human hand in the projection display picture, wherein the effective click event is only if the single-point signal coordinate and the virtual target object have a collision relation.

The single-point signal coordinates of the human hand can be displayed and verified before virtual interaction begins, firstly, a user stands in a scanning range of the radar device before virtual interaction begins, the radar device scans and obtains a basic outline of the user, then the position of the human hand is recognized, and the single-point signal coordinates output after filtering and inhibiting are displayed in a projection display picture in a marking point mode, so that when the hand of the user performs actions, the position of the hand of the user in the projection display picture can be made clear, and the accuracy of butterfly catching of the user is improved.

Step S3: and judging whether a collision relation occurs between the position information of the specified part of the obstacle and the position information of the virtual target object in the projection display picture, and if so, outputting a corresponding dynamic effect to the projection display picture.

The method for judging whether the collision relation occurs between the specified part of the obstacle and the virtual target object comprises the following steps: judging whether the single-point signal coordinates of the human hand coincide with the current dynamic coordinate points of the virtual target object in real time, if so, determining that a collision relation occurs, and if so, outputting a specified dynamic effect in the projection display picture, wherein the human hand can be considered to catch a virtual butterfly; if the virtual butterfly is not overlapped, the collision relation does not occur, the human hand is considered not to catch the virtual butterfly, and the dynamic effect is not output.

In addition, a certain touch error range can exist between the single-point signal coordinates of the human hand in the collision relationship and the dynamic coordinate points of the virtual target object, namely, the dynamic coordinate points of the virtual target object are expanded outwards into a coordinate range, and when the single-point signal coordinates of the human hand fall into the coordinate range of the virtual target object, the collision relationship between the human hand and the virtual target object is determined, so that the success rate of butterfly capturing of a user is improved.

The user can set the output dynamic effect by utilizing the client in advance, the user inputs the dynamic effect of characters, images and/or sounds displayed after the butterfly capturing is successful through the client, and when the virtual butterfly is captured by the hand of the human body, the corresponding dynamic effect of the characters, the images and/or the sounds is output so as to improve the interaction interest. The command action triggered and executed after the butterfly capturing is successful can be preset, for example, the scoring command is triggered and executed after the butterfly capturing is successful, the timing operation can be started when the interactive game is started, and the timing operation is finished after the butterfly capturing is successful, so that the time required by the butterfly capturing is counted, and the like, and the interactive diversity is increased.
