Hologram makers, render 3D projections whether it’s inside a glass tube or suspended in thin air. 3D multidimensional images enable users to interact with content in a totally unique way from a 360-degree seeing point. The way to the operation of holographic projectors is the 3D image. A holographic projector utilizes part illuminations reflected together from multiple viewing angles of the subject in a combined form to reproduce a picture of the subject in a 3D state.

Our system produces holographic projections created through anticipated picture by refraction through the interference design, losing barely any light, and working with substantially more productivity. Our system uses a raspberry pi controller based system to achieve such holographic projections. We then use a display to provide part live videos to the projector setup in order to get the desired 3d hologram. Our frame is constructed to project an image in the 3D state using a clear pyramid frame in an accurately designed 3d reflective state.
Now we use a gesture sensing board for raspberry pi to detect the gestures by the user and then use It to forward or rewind to previous projections without even touching the panel. Thus we successfully an efficiently designed 3D holographic display system with gesture interface controller.
Project Description:
Raspberry Pi 3 B: Raspberry Pi is a Microprocessor which has 40 pins with 27 GPIO pins, it has a 1 Giga Bytes of RAM and a SD card slot for the storage or the ROM,it can be used as a mini computer for low computing operations, it has a dual band LAN, faster Ethernet, Bluetooth, it also has USB and HDMI ports for connecting devices. This device can be used as a server which we are doing in this project.
Micro SD card: You will need a minimum of 8 gigabytes SD card for this project, this SD card is used as the ROM of the raspberry pi. Use 32 Gigabyte or 64 Gigabytes of
Display: You can use any kind of display for the project, like monitors, TV or any size display that fits your requirement to configure the Pi.
Power Supply: Raspberry Pi needs a power supply of 5V and 2A Micro USB type.
Mouse and keyboard: You will need this to control, monitor, and to configure the Pi.
Pyramid structured Glass: You can build a pyramid glass structure for the 3D projections.
GY-521 module: This module has a MPU-6050 sensor which has MEMS accelerometer and MEMS gyro in a single chip, this gives the data of all the three dimensions and the tilt angle of the robot. The module also consists of a magnetometer(compass).
Project Implementation:
Install the Raspbian OS into the SD card, and boot the Raspberry Pi.
Install Python IDE 3 in Raspberry Pi.
Install the Audio dependencies in order to use the speakers to play even the audio.
Connect your Display, keypad to the raspberry pi.
Fix your Glass pyramid, keypad to the display.
Write a Python program with which you can control the video with the gesture sensor.
You can change the video, forward or rewind using the gesture sensor.
Project Brief:The Raspberry Pi when configured and all the required software has been installed then the Pi is ready to be used as a 3D holographic video player.
Software requirements:
Raspbian OS(Debian Linux): Raspbian operating systems are based on Linux, Raspberry pi are also compatible with Windows and IOS but prefer any Linux based OS
Python IDE 3: Python IDE 3 is compiler where you can write and compile python program.
Programing Language:
Linux (terminal commands)
Python
Kit required to develop 3D Holographic Projector:
