As you can see, the world of virtual reality is gradually molding; Google has also taken the lead in launching a virtual reality equipment based on smartphones, Xiaobian also experiences, feeling not bad.
There is no doubt that virtual reality is entering our lives, and virtual reality live broadcast is gradually emerging. But in general, virtual reality live broadcast is also very small, there are not many resources; and many virtual reality live broadcasts have restrictions on the number of access devices due to bandwidth limits. Since this, let's come to DIY a set of virtual reality live broadcast systems! (Note: This project comes from instructables.)
Step 1: Materials and components configuration
To achieve this project, you need the following hardware:
A mobile phone supporting cardboard
Google Cardboard (because Google has publicly designed design, there are many different manufacturers' compatible versions)
Two computers
Two different network cameras (must be driven, otherwise the Windows system cannot identify)
Three standard servir
Camera bracket and related 3D printing components (file click here to download)
Small bread board
12 jumpers
USB A turn USB B line
AA battery box
4 AA batteries
Arduino Uno
Some screws
In addition, you also need these software:
Processing 2.0 (optional, if you don't want to change the source code, no use)
TrinusVR
Arduino
Skype
VRTD
Step 2: Motion unit assembly
First 3D printing the necessary structural pieces.
Different steering machines cooperate with different structures, specific views.
Step 3: Electronic parts
The wiring diagram is as above, and Arduino is used to control three steering gears that are powered by 4 AA batteries because Arduino cannot simultaneously. These three steering gears provide three degrees of freedom for the final equipment. The actual connection is as follows:
Step 4: Upload code
This project is based on a standard Firmata protocol that allows Arduino-based real-time communication interactions more simple, and data can be processed to the PC. The steps to set the standard Firmata protocol are as follows:
Use USB A to the USB B line, open Arduino IDE and connect Arduino UNO to PC;
Click File->examples->firmata->standardFirmata, load the necessary code templates into IDE;
Click Tools->board->Arduino UNO to determine the development board;
Tools->serial port-> (Serial interface name), set the interface connected to Arduino here;
Click the arrow symbol to upload the Standard Firmata protocol to Arduino, if there is no error, upload success.
You can use the FIRMATA TEST application to test the standard Firmata protocol to be successful. In these, you can see the definition of the interface, here we use the pins 8, 9, and 10, change the type of these three pins to "servo".
Step 5: Set virtual reality applications
Most of the virtual reality applications are wearing, we choose a Cardboard compatible version here. Our data processing is performed on the computer, and we need TRINUSVR software to provide video streams for Cardboard. TrinusVR Download and Installation Method Click here.
Step 6: VRTD software
This project will use the custom software VRTD (Virtual Reality Teleconferencing device "written using Processing 2.0 to implement remote control of the virtual reality device, which is divided into two parts VRTD_SENDER and VRTD_RECEIVER.
VRTD_Sender uses on a computer that tracks the header motion generating data and uploads the data to a specific IP address. The IP address belongs to another computer, which is running on the computer, which can accept video data generated by the left and right cameras connected thereto, and simultaneously control the camera according to the data transmitted by VRTD_Sender. Sports of the steering gear.
So how do users see the video broadcast? A very clever method is used here: directly transmit shared video data through video software such as Skype or QQ. The specific configuration steps are as follows:
Prepare two computers that have been installed on the Windows system, named A and B, respectively;
Connect computer A to Cardboard and run VRTD_Sender;
Connect computer B to a virtual reality device and run VRTD_Receiver;
Set the interface of the left and right network cameras and Arduino in VRTD_Receiver;
Run Skype software on both computers and turn on the screen sharing;
Enter the IP address of computer B in VRTD_Sender;
Wear a virtual reality device that controls the cursor of the mouse and thereby controls the servo connected to the Arduino connected to the computer B.
Note: Only one computer can also complete this item, running VRTD_RECEIVER and VRTD_SENDER, entering the local 127.0.0.1 when entering an IP address.
Step 7: Finish
It is done here, and the author John Choi of the project has been open to the relevant CAD and handling documents, it is too good!
